| FEES AND EXPENSES OF THE FUND | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund. Each share class has different expenses, but represents an investment in the same Fund. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| For Class A Shares, you may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund or in other Janus mutual funds. More information about these and other discounts, as well as eligibility requirements for each share class, is available from your financial professional and in the “Purchases” section on page 36 of the Fund’s Prospectus and in the “Purchases” section on page 55 of the Fund’s Statement of Additional Information. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| EXAMPLE: | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The following Example is based on expenses without waivers. The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The Example assumes that you invest $10,000 in the Fund for the time periods indicated and reinvest all dividends and distributions. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, including the maximum amount of the capital protection fee, without waivers, remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| If Shares are not redeemed: | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
|
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Portfolio Turnover: | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| PRINCIPAL INVESTMENT STRATEGIES | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The Fund seeks growth of capital to the extent consistent with maintaining protection against significant downside movement of the net asset value (“NAV”) per share of each share class of the Fund. Specifically, the portfolio manager manages the Fund’s assets in an effort to ensure that the NAV for each share class will not fall below 80% of the highest NAV attained separately by each share class during the life of the Fund, reduced for dividends, distributions, any extraordinary expenses, and certain extraordinary items (for each share class, the “Protected NAV”). A reduction of the NAV can be described further by using distributions as an example. In the event the Fund declares dividends from net investment income and capital gains distributions, which normally occurs in December, the Protected NAV per share will be adjusted down so that the relative protection level remains at the level in place prior to the distribution. While the Protected NAV per share is changed as a result of a distribution, the protected value of your account balance does not change, assuming you reinvest your distribution. For example, on a day the highest NAV per share of a share class is reached at $11.00, the Protected NAV per share is set at $8.80, which is 80% of the highest NAV per share. When the highest NAV per share increases to $12.50, the Protected NAV per share is set at $10.00, which is 80% of the highest NAV. On a day the NAV per share is $12.00, the Fund declares a per share distribution of $1.00. The result of the distribution is that the NAV per share is reduced from $12.00 to $11.00. The Protected NAV per share is also reduced so that the Protected NAV per share is the same relative to the post-distribution NAV per share of $11.00 as it was to the pre-distribution NAV per share of $12.00. The Protected NAV per share of $10.00 was 83.3% of the pre-distribution NAV per share of $12.00 per share and the post-distribution Protected NAV per share is adjusted to $9.17, which is 83.3% of the post-distribution NAV per share. Additional information regarding how the Protected NAV per share is adjusted following a distribution is included in Appendix A. The reduction for extraordinary expenses and extraordinary items from the NAV would have a similar result. In general, protection for the Fund means, as the NAV per share for a share class rises, the Protected NAV also rises and becomes the new Protected NAV regardless of whether the share class’ NAV per share subsequently declines or fails to achieve a new high threshold. However, as a share class’ NAV declines towards the Protected NAV, more of the Fund’s assets will be comprised of cash and other investments, called the “Protection Component,” as further described below. In order to minimize the effect of equity market volatility on the NAV per share for a share class, the Fund allocates its portfolio assets between two investment components. Through its first component, the “Equity Component,” the Fund seeks to achieve growth of capital by investing primarily in common stocks selected for their growth potential. Although the Fund may invest in companies of any size, it generally invests in larger, more established companies. The Equity Component may also consist of derivatives such as options and futures. Through its second component, the “Protection Component,” the Fund seeks to limit downside risk by investing in cash and other investments including, but not limited to, money market instruments, U.S. Treasuries, and other equity market risk reducing instruments, such as short index futures. Due to equity market conditions and the Fund’s overall risk profile, the amount of Fund assets allocated to the Protection Component may, at times, be significant. The Fund’s allocation between the Equity Component and the Protection Component will vary over time. Up to 100% of assets may be allocated to either component. The portfolio manager applies a “bottom up” approach in choosing common stock investments for the Equity Component. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. As part of the Equity Component, the Fund may invest in foreign equity and debt securities, which may include investments in emerging markets. As noted above, the Fund may also invest the assets of either component in derivatives, which are instruments that have a value derived from an underlying asset, such as stocks, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) including, but not limited to, futures and over-the-counter and exchange-traded put or call options for various purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. In an effort to protect against significant downward movement of the NAV per share for a share class, the Fund has entered into a Capital Protection Agreement with BNP Paribas Prime Brokerage, Inc., a U.S. registered broker-dealer and a member of FINRA (the “Capital Protection Provider”). Pursuant to the Capital Protection Agreement, under certain conditions, the Capital Protection Provider will provide capital protection to the Fund (the “Protection”) in the event that any share class’ NAV per share falls below its Protected NAV. Any one share class falling below its Protected NAV will trigger the Protection and liquidation of the Fund and each of its share classes, regardless of whether the NAV of any other share class is above its Protected NAV. The Capital Protection Provider has agreed to initially extend $1.5 billion in aggregate protection coverage to the Fund with such amount being reviewed periodically to determine whether additional coverage is necessary or available to support the Fund’s rising assets (the “Maximum Settlement Amount”). As such, under the Capital Protection Agreement, the NAV of each share class is protected to at least the Protected NAV for such share class, subject to an aggregate limit on the overall payout to the Fund of the Maximum Settlement Amount. In the event that the Protection is triggered, meaning at least one share class’ NAV is below its Protected NAV, the Capital Protection Provider is obligated to pay the Fund the “Settlement Amount,” which is the lesser of (i) the sum of the shortfall amounts per share class (the “Aggregate Shortfall Amount”) and (ii) the Maximum Settlement Amount. For each share class, the shortfall amount is calculated by first establishing, among those share classes that have a NAV below their Protected NAV, the highest percentage difference among all of those share classes between the Protected NAV per share and the then-current NAV per share, and applying that percentage to each Fund share class’ then-current NAV per share. The Aggregate Shortfall Amount is thus allocated on a pro rata basis to each share class. In order to comply with the terms of the Capital Protection Agreement, the Fund must provide certain information to the Capital Protection Provider and the Fund’s portfolio manager is required to manage the Fund within certain risk parameters as identified on a daily basis by the Capital Protection Provider based on a risk allocation methodology. This risk allocation methodology factors in, among other things, market volatility, the Fund’s exposure to industries, sectors, or countries, and liquidity of the Fund’s holdings. In general, as equity markets are rising, the Fund’s allocation to the Equity Component will rise with a goal of taking advantage of any potential future market increase, and as equity markets are falling, the Fund’s portfolio manager will allocate more of the Fund’s assets to the Protection Component in an effort to protect the Fund from a potential ongoing decrease in the market. The Fund’s asset allocation will vary over time depending on equity market conditions and the Fund’s portfolio composition. As a result, the Fund’s allocation to each investment component could change as frequently as daily, resulting in a higher portfolio turnover rate than other mutual funds. The Capital Protection Agreement has an initial term of 10 years and may be extended for additional 10-year terms by mutual agreement of the Fund and the Capital Protection Provider. Under certain circumstances, the Capital Protection Agreement may be terminated prior to the expiration of any effective term, which in any case would become the “Termination Date.” Only shareholders who hold their shares on such Termination Date will be covered by the Protection. In the event of such termination of the Capital Protection Agreement, the Fund will terminate and liquidate and the Capital Protection Provider will pay the Fund any amounts due related to the Protection. This Prospectus serves as advance notice to you of any such liquidation. There are limited circumstances in which the Protection also terminates on the Termination Date, meaning the Capital Protection Provider is not obligated to pay any amounts to the Fund even where the NAV of a share class is below its Protected NAV. These circumstances are described further below under “Principal Investment Risks” as “Capital Protection Termination Risk.” It is important to understand that the Capital Protection Agreement is a financial product that is intended to protect the Fund against significant market declines and does not in any way constitute any form of insurance. In addition, the Capital Protection Provider is not an insurance company or an insurance provider, nor is it acting as an adviser or subadviser for the Fund. |

| PRINCIPAL INVESTMENT RISKS | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The biggest risk is that the Fund’s returns will vary, and you could lose money, despite the Capital Protection Agreement. Common stocks tend to be more volatile than many other investment choices. Because the NAV per share for a share class is protected to at least 80%, and not 100%, of its highest attained NAV since the inception of the share class (as reduced to account for dividends, distributions, any extraordinary expenses, and certain extraordinary items), it is possible that in the event that equity markets fall, you could lose money, even if the Protection is triggered. In addition, if the Capital Protection Agreement does not work as intended or has been terminated, you could lose money. Because the Protected NAV is reduced by dividends, distributions, any extraordinary expenses, and certain extraordinary items, the amount of Protection could be less than 80% of the highest attained NAV for your class of shares, meaning the Protected NAV does not become a static number that only increases. To the extent that the protected amount owed to the Fund exceeds the Maximum Settlement Amount ($1.5 billion), neither the Fund nor Janus Capital will cover any shortfall amount, so you could lose money including amounts that would have otherwise been protected. The Protected NAV for each share class will be posted on the Janus websites at janus.com/advisor/mutual-funds, or janus.com/allfunds for shareholders of Class D Shares. Any change to the Protected NAV will be updated within one business day. Because any one share class falling below its Protected NAV can alone trigger the Protection and liquidation of the Fund, shareholders should review the Protected NAV for each share class prior to purchasing shares of this Fund, keeping in mind that each share class has different fees and expenses that impact the NAV. Shareholders considering an investment in Class A Shares should pay particular attention to the Protected NAV of each share class as part of their investment decision given that Class A Shares have an upfront sales load that once paid, is not reimbursed when the Fund liquidates. Allocation Risk. Because there are risk parameters within which the portfolio manager must manage the Fund’s assets in order to maintain the Protection, the Fund’s ability to take certain investment actions that the portfolio manager might otherwise take may be limited. More specifically, complying with the provisions of the Capital Protection Agreement may impact the Fund’s allocation of assets to and within the Equity Component during the life of the Fund and/or affect the portfolio manager’s ability to respond to changing equity market conditions. This could limit the Fund’s ability to capture certain market gains when the allocations are more heavily weighted to the Protection Component. Conversely, as equity markets are rising or displaying signs of relative stability, the Fund may have more of the portfolio weighted towards assets considered to have higher risk which could increase the potential for loss of return for the Fund. Generally, the risk parameters may lead the portfolio manager to take certain investment actions that he otherwise would not take when allocating the Fund’s assets between and within the Equity Component and the Protection Component. This allocation process can have an adverse effect on the performance of the Fund, especially during periods of increased equity market volatility. The risk allocation methodology is designed so that the NAV of each share class does not fall below its Protected NAV and, if successful, protection payments are not triggered. It is possible, however, that the risk allocation methodology may not work as designed or intended and may cause the Fund to trigger the Protection, resulting in the termination of the Fund. In addition, the allocation of the Fund’s assets between and within the Equity Component and the Protection Component may result in a high portfolio turnover rate and additional transaction costs, such as brokerage commissions, which can impact the Fund’s returns. Because the portfolio manager allocates the Fund’s assets between and within the Equity Component and Protection Component daily according to a risk allocation methodology, there is the risk that a sudden intraday market drop may occur before the Fund’s Equity Component exposure can be reduced. Additionally, if the Fund fails to allocate its assets according to the risk allocation methodology, the Capital Protection Provider will have the option to terminate the Capital Protection Agreement, resulting in the Fund allocating 100% of its assets solely to cash and the liquidation of the Fund. Under these circumstances, the Capital Protection Provider will pay any amounts it is obligated to pay to the Fund. Market Underperformance Risk. The Fund’s use of the risk allocation methodology and the resulting allocation between and within the Equity Component and the Protection Component may cause the Fund to underperform its primary benchmark and/or other similarly situated growth funds. This underperformance may be a result of the portfolio manager’s inability to reallocate Fund assets to respond to rising equity market conditions as quickly as another fund that invests primarily in equity securities. In addition, to maintain compliance with the risk parameters, the Fund may need to liquidate a position, or forego an investment that could have otherwise contributed to Fund performance. Under certain circumstances, the Capital Protection Agreement may require that all of the Fund’s assets be fully allocated to the Protection Component, thus limiting the upside potential for Fund returns during this period. The use of the risk allocation methodology may also impact the Fund’s performance in the event that it does not work as intended, potentially subjecting the Fund to additional expenses as a result of increased trading or allocating a larger portion of the Fund’s assets than necessary to either the Equity Component or Protection Component. Because the Fund may reallocate its assets between and within the Equity Component and the Protection Component as frequently as daily, the Fund’s reallocation may cause it to experience an increase in its portfolio turnover rate resulting in higher costs, which may have a negative effect on the Fund’s performance, particularly during periods of relative instability in equity markets. The Fund’s payment of the capital protection fee to the Capital Protection Provider may also result in the Fund underperforming its primary benchmark and/or other similarly situated growth funds that do not pay a protection fee. Capital Protection Termination Risk. There is a risk that the Protection could terminate. The terms and conditions of the Capital Protection Agreement are designed to protect against certain market risks inherent in any equity investment. It does not protect against certain actions or omissions that constitute gross negligence, fraud, bad faith, willful misconduct, or a criminal act on the part of the Fund, Janus Capital or certain key employees of Janus Capital, or the Fund’s custodian, that negatively impacts a share class’ NAV. Such events will result in the termination of the Protection without any obligation by the Capital Protection Provider, and therefore by the Parent Guarantor, to make any payment to the Fund. The Fund will liquidate in these events, and shareholders will receive the then-current NAV of their share class, which could be below the Protected NAV. Neither the Fund nor Janus Capital is obligated to make any payment to the Fund or cover any shortfall. Therefore, in the event that the Protection is terminated as a result of such events, you could lose money as a result of the Fund losing the Protection under the Capital Protection Agreement, including amounts that would have otherwise been protected. This means that you could receive less than 80% of your investment. Early Termination Events Risk. While the Capital Protection Agreement has an initial 10-year term that may be extended, there is a risk that the Capital Protection Agreement could terminate earlier under various scenarios at the option of the Capital Protection Provider, which are considered Early Termination Events. In such events, the Capital Protection Provider will be obligated to make the payment of the Settlement Amount, if due, to the Fund and the Fund will liquidate. Shareholders receive the higher of their Protected NAV or the then-current NAV for their share class, which will include any Settlement Amount due to the Fund. Examples of “Early Termination Events” include, but not are not limited to (1) if the Fund, Janus Capital, or the Fund’s custodian, fails to comply with certain terms and conditions of the Capital Protection Agreement, including the failure to reallocate Fund assets when such assets fall outside the specified risk parameters, or (2) if the aggregate value of the Fund’s shares outstanding results in the Protection exceeding the Maximum Settlement Amount. The Fund is also expected to liquidate and the Capital Protection Agreement will terminate if, pursuant to the terms of the Capital Protection Agreement, the Protection is triggered. In addition, to the extent that the introduction of laws or a change of law, in each case, not known as of the date of the Capital Protection Agreement results in a new or increased cost of capital or collateral for the Capital Protection Provider or its parent company, the Fund’s Board of Trustees will make a determination whether to approve the Fund paying such increased costs to the Capital Protection Provider or to terminate the Capital Protection Agreement. Only shareholders who hold their shares on the Termination Date are covered by the Protection. Shareholders who redeem prior to the Termination Date receive the then-current NAV which will be higher than the Protected NAV for their share class and will not include any payment of the Protection. Maximum Settlement Amount Risk. The Capital Protection Agreement currently covers the outstanding shares of each class of shares offered by the Fund having an aggregate protected amount up to an initial value of $1.5 billion. If the Maximum Settlement Amount exceeds $1.5 billion without any additional coverage being extended to the Fund, the Capital Protection Provider will not be liable for any Settlement Amount payment in excess of $1.5 billion. None of the Fund, Janus Capital, or any affiliate thereof, will be responsible for any portion of the Settlement Amount, including any amounts which may exceed the Maximum Settlement Amount. Therefore, although the Protection applies, you could lose money to the extent the Aggregate Shortfall Amount exceeds the Maximum Settlement Amount including amounts that would have otherwise been protected. This means that you could receive less than 80% of your investment. In any event, as the Fund’s assets grow, the Fund intends to take such actions as may be deemed necessary, including limiting purchases, to limit the Aggregate Shortfall Amount to a level so that it does not exceed the Maximum Settlement Amount, but there is no guarantee that such efforts will be successful. There is no guarantee that the Capital Protection Provider will agree to extend coverage beyond $1.5 billion. Liquidation Risk. Although the risk allocation methodology is designed so that the NAV of each share class does not fall below its Protected NAV, there is the possibility that the risk allocation methodology may not work as designed or redemptions, particularly a large redemption, may impact the allocation process, and the NAV of any share class falls below its Protected NAV. If this happens, it is expected that the Fund will liquidate as soon as possible following the event and receive payment of the Settlement Amount from the Capital Protection Provider. The NAV of one share class falling below its Protected NAV will result in the Protection being triggered and, as a result, the liquidation of the entire Fund, even though the NAV of one or more other share classes remains at or above its Protected NAV. Other events described in this Prospectus may, at the discretion of the Fund or Capital Protection Provider, as applicable, also terminate the Capital Protection Agreement resulting in payment of the Settlement Amount and liquidation of the Fund. In the event the Protection is triggered and the Fund begins the liquidation process, no other purchases will be permitted, and the payment of redemption proceeds will be suspended, likely from the day the Protection is triggered; shareholders will receive the higher of the then-current NAV per share or the Protected NAV per share for their share class, which will include any Settlement Amount due to the Fund. Redemptions are taxable events. This Prospectus serves as advance notice to shareholders of any rejection of purchases, suspension of the payment of redemption proceeds, and liquidation of the Fund. In the event that the Capital Protection Agreement is terminated and the Fund begins the liquidation process, Janus Capital will make such information available at janus.com/advisor/mutual-funds or janus.com/allfunds for shareholders of Class D Shares. Notice of the Fund liquidation will otherwise be made when you receive your redemption proceeds. For illustrative purposes to understand a scenario where the Protection is triggered and the Fund proceeds to liquidation, see below: Protected NAV across all share classes is $10.00 –
Opportunity Cost Risk. It is possible that under the terms of the Capital Protection Agreement, the Fund’s allocation to the Equity Component could drop to a low level or be eliminated altogether, especially during periods of heightened volatility in equity markets. This would reduce the Fund’s ability to participate in upward equity market movements, and therefore, represents loss of opportunity compared to a fund that is fully invested in equity securities. Counterparty Risk (Capital Protection Provider and its Parent Company). A shareholder’s ability to receive the Protected NAV from the Fund is dependent on the Fund’s ability to collect the Settlement Amount from the Capital Protection Provider pursuant to the terms of the Capital Protection Agreement or from the Capital Protection Provider’s parent under a separate parent guaranty. Fund transactions involving a counterparty, such as the Capital Protection Provider, are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. As such, the Fund’s ability to benefit from the Protection may depend on the Capital Protection Provider’s, as well as its parent company’s, financial condition. As an added measure of protection, BNP Paribas, the parent company of the Capital Protection Provider, has issued an absolute, irrevocable and continuing guaranty pursuant to which it guarantees any and all financial obligations of the Capital Protection Provider under the Capital Protection Agreement. There is, however, a risk that the Capital Protection Provider’s parent company may not fulfill its obligations under the guaranty it has issued. Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or multiple companies in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. The Fund’s use of the risk allocation methodology is intended to protect against significant downward movement of the NAV per share for a share class, particularly in times of heightened volatility in the equity markets, but the methodology may not protect the Fund if equity markets take a sudden and/or significant fall. Growth Securities Risk. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. The price of a “growth” security may be impacted if the company does not realize its anticipated potential or if there is a shift in the market to favor other types of securities. Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations to the Fund. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited. Foreign Exposure Risk. The Fund may have significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. A market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries. Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities are exposed to a number of additional risks, which may result from less government supervision and regulation of business and industry practices, stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. Portfolio Turnover Risk. Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders. The risk allocation methodology utilized by the Fund may increase the level of portfolio turnover. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. |

These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. | ||||||

| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund seeks growth of capital to the extent consistent with maintaining protection against significant downside movement of the net asset value (“NAV”) per share of each share class of the Fund. Specifically, the portfolio manager manages the Fund’s assets in an effort to ensure that the NAV for each share class will not fall below 80% of the highest NAV attained separately by each share class during the life of the Fund, reduced for dividends, distributions, any extraordinary expenses, and certain extraordinary items (for each share class, the “Protected NAV”). A reduction of the NAV can be described further by using distributions as an example. In the event the Fund declares dividends from net investment income and capital gains distributions, which normally occurs in December, the Protected NAV per share will be adjusted down so that the relative protection level remains at the level in place prior to the distribution. While the Protected NAV per share is changed as a result of a distribution, the protected value of your account balance does not change, assuming you reinvest your distribution. For example, on a day the highest NAV per share of a share class is reached at $11.00, the Protected NAV per share is set at $8.80, which is 80% of the highest NAV per share. When the highest NAV per share increases to $12.50, the Protected NAV per share is set at $10.00, which is 80% of the highest NAV. On a day the NAV per share is $12.00, the Fund declares a per share distribution of $1.00. The result of the distribution is that the NAV per share is reduced from $12.00 to $11.00. The Protected NAV per share is also reduced so that the Protected NAV per share is the same relative to the post-distribution NAV per share of $11.00 as it was to the pre-distribution NAV per share of $12.00. The Protected NAV per share of $10.00 was 83.3% of the pre-distribution NAV per share of $12.00 per share and the post-distribution Protected NAV per share is adjusted to $9.17, which is 83.3% of the post-distribution NAV per share. Additional information regarding how the Protected NAV per share is adjusted following a distribution is included in Appendix A. The reduction for extraordinary expenses and extraordinary items from the NAV would have a similar result. In general, protection for the Fund means, as the NAV per share for a share class rises, the Protected NAV also rises and becomes the new Protected NAV regardless of whether the share class’ NAV per share subsequently declines or fails to achieve a new high threshold. However, as a share class’ NAV declines towards the Protected NAV, more of the Fund’s assets will be comprised of cash and other investments, called the “Protection Component,” as further described below. In order to minimize the effect of equity market volatility on the NAV per share for a share class, the Fund allocates its portfolio assets between two investment components. Through its first component, the “Equity Component,” the Fund seeks to achieve growth of capital by investing primarily in common stocks selected for their growth potential. Although the Fund may invest in companies of any size, it generally invests in larger, more established companies. The Equity Component may also consist of derivatives such as options and futures. Through its second component, the “Protection Component,” the Fund seeks to limit downside risk by investing in cash and other investments including, but not limited to, money market instruments, U.S. Treasuries, and other equity market risk reducing instruments, such as short index futures. Due to equity market conditions and the Fund’s overall risk profile, the amount of Fund assets allocated to the Protection Component may, at times, be significant. The Fund’s allocation between the Equity Component and the Protection Component will vary over time. Up to 100% of assets may be allocated to either component. The portfolio manager applies a “bottom up” approach in choosing common stock investments for the Equity Component. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. As part of the Equity Component, the Fund may invest in foreign equity and debt securities, which may include investments in emerging markets. As noted above, the Fund may also invest the assets of either component in derivatives, which are instruments that have a value derived from an underlying asset, such as stocks, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) including, but not limited to, futures and over-the-counter and exchange-traded put or call options for various purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. In an effort to protect against significant downward movement of the NAV per share for a share class, the Fund has entered into a Capital Protection Agreement with BNP Paribas Prime Brokerage, Inc., a U.S. registered broker-dealer and a member of FINRA (the “Capital Protection Provider”). Pursuant to the Capital Protection Agreement, under certain conditions, the Capital Protection Provider will provide capital protection to the Fund (the “Protection”) in the event that any share class’ NAV per share falls below its Protected NAV. Any one share class falling below its Protected NAV will trigger the Protection and liquidation of the Fund and each of its share classes, regardless of whether the NAV of any other share class is above its Protected NAV. The Capital Protection Provider has agreed to initially extend $1.5 billion in aggregate protection coverage to the Fund with such amount being reviewed periodically to determine whether additional coverage is necessary or available to support the Fund’s rising assets (the “Maximum Settlement Amount”). As such, under the Capital Protection Agreement, the NAV of each share class is protected to at least the Protected NAV for such share class, subject to an aggregate limit on the overall payout to the Fund of the Maximum Settlement Amount. In the event that the Protection is triggered, meaning at least one share class’ NAV is below its Protected NAV, the Capital Protection Provider is obligated to pay the Fund the “Settlement Amount,” which is the lesser of (i) the sum of the shortfall amounts per share class (the “Aggregate Shortfall Amount”) and (ii) the Maximum Settlement Amount. For each share class, the shortfall amount is calculated by first establishing, among those share classes that have a NAV below their Protected NAV, the highest percentage difference among all of those share classes between the Protected NAV per share and the then-current NAV per share, and applying that percentage to each Fund share class’ then-current NAV per share. The Aggregate Shortfall Amount is thus allocated on a pro rata basis to each share class. In order to comply with the terms of the Capital Protection Agreement, the Fund must provide certain information to the Capital Protection Provider and the Fund’s portfolio manager is required to manage the Fund within certain risk parameters as identified on a daily basis by the Capital Protection Provider based on a risk allocation methodology. This risk allocation methodology factors in, among other things, market volatility, the Fund’s exposure to industries, sectors, or countries, and liquidity of the Fund’s holdings. In general, as equity markets are rising, the Fund’s allocation to the Equity Component will rise with a goal of taking advantage of any potential future market increase, and as equity markets are falling, the Fund’s portfolio manager will allocate more of the Fund’s assets to the Protection Component in an effort to protect the Fund from a potential ongoing decrease in the market. The Fund’s asset allocation will vary over time depending on equity market conditions and the Fund’s portfolio composition. As a result, the Fund’s allocation to each investment component could change as frequently as daily, resulting in a higher portfolio turnover rate than other mutual funds. The Capital Protection Agreement has an initial term of 10 years and may be extended for additional 10-year terms by mutual agreement of the Fund and the Capital Protection Provider. Under certain circumstances, the Capital Protection Agreement may be terminated prior to the expiration of any effective term, which in any case would become the “Termination Date.” Only shareholders who hold their shares on such Termination Date will be covered by the Protection. In the event of such termination of the Capital Protection Agreement, the Fund will terminate and liquidate and the Capital Protection Provider will pay the Fund any amounts due related to the Protection. This Prospectus serves as advance notice to you of any such liquidation. There are limited circumstances in which the Protection also terminates on the Termination Date, meaning the Capital Protection Provider is not obligated to pay any amounts to the Fund even where the NAV of a share class is below its Protected NAV. These circumstances are described further below under “Principal Investment Risks” as “Capital Protection Termination Risk.” It is important to understand that the Capital Protection Agreement is a financial product that is intended to protect the Fund against significant market declines and does not in any way constitute any form of insurance. In addition, the Capital Protection Provider is not an insurance company or an insurance provider, nor is it acting as an adviser or subadviser for the Fund. |

| Risk [Heading] | rr_RiskHeading | PRINCIPAL INVESTMENT RISKS | ||||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | The biggest risk is that the Fund’s returns will vary, and you could lose money, despite the Capital Protection Agreement. Common stocks tend to be more volatile than many other investment choices. Because the NAV per share for a share class is protected to at least 80%, and not 100%, of its highest attained NAV since the inception of the share class (as reduced to account for dividends, distributions, any extraordinary expenses, and certain extraordinary items), it is possible that in the event that equity markets fall, you could lose money, even if the Protection is triggered. In addition, if the Capital Protection Agreement does not work as intended or has been terminated, you could lose money. Because the Protected NAV is reduced by dividends, distributions, any extraordinary expenses, and certain extraordinary items, the amount of Protection could be less than 80% of the highest attained NAV for your class of shares, meaning the Protected NAV does not become a static number that only increases. To the extent that the protected amount owed to the Fund exceeds the Maximum Settlement Amount ($1.5 billion), neither the Fund nor Janus Capital will cover any shortfall amount, so you could lose money including amounts that would have otherwise been protected. The Protected NAV for each share class will be posted on the Janus websites at janus.com/advisor/mutual-funds, or janus.com/allfunds for shareholders of Class D Shares. Any change to the Protected NAV will be updated within one business day. Because any one share class falling below its Protected NAV can alone trigger the Protection and liquidation of the Fund, shareholders should review the Protected NAV for each share class prior to purchasing shares of this Fund, keeping in mind that each share class has different fees and expenses that impact the NAV. Shareholders considering an investment in Class A Shares should pay particular attention to the Protected NAV of each share class as part of their investment decision given that Class A Shares have an upfront sales load that once paid, is not reimbursed when the Fund liquidates. Allocation Risk. Because there are risk parameters within which the portfolio manager must manage the Fund’s assets in order to maintain the Protection, the Fund’s ability to take certain investment actions that the portfolio manager might otherwise take may be limited. More specifically, complying with the provisions of the Capital Protection Agreement may impact the Fund’s allocation of assets to and within the Equity Component during the life of the Fund and/or affect the portfolio manager’s ability to respond to changing equity market conditions. This could limit the Fund’s ability to capture certain market gains when the allocations are more heavily weighted to the Protection Component. Conversely, as equity markets are rising or displaying signs of relative stability, the Fund may have more of the portfolio weighted towards assets considered to have higher risk which could increase the potential for loss of return for the Fund. Generally, the risk parameters may lead the portfolio manager to take certain investment actions that he otherwise would not take when allocating the Fund’s assets between and within the Equity Component and the Protection Component. This allocation process can have an adverse effect on the performance of the Fund, especially during periods of increased equity market volatility. The risk allocation methodology is designed so that the NAV of each share class does not fall below its Protected NAV and, if successful, protection payments are not triggered. It is possible, however, that the risk allocation methodology may not work as designed or intended and may cause the Fund to trigger the Protection, resulting in the termination of the Fund. In addition, the allocation of the Fund’s assets between and within the Equity Component and the Protection Component may result in a high portfolio turnover rate and additional transaction costs, such as brokerage commissions, which can impact the Fund’s returns. Because the portfolio manager allocates the Fund’s assets between and within the Equity Component and Protection Component daily according to a risk allocation methodology, there is the risk that a sudden intraday market drop may occur before the Fund’s Equity Component exposure can be reduced. Additionally, if the Fund fails to allocate its assets according to the risk allocation methodology, the Capital Protection Provider will have the option to terminate the Capital Protection Agreement, resulting in the Fund allocating 100% of its assets solely to cash and the liquidation of the Fund. Under these circumstances, the Capital Protection Provider will pay any amounts it is obligated to pay to the Fund. Market Underperformance Risk. The Fund’s use of the risk allocation methodology and the resulting allocation between and within the Equity Component and the Protection Component may cause the Fund to underperform its primary benchmark and/or other similarly situated growth funds. This underperformance may be a result of the portfolio manager’s inability to reallocate Fund assets to respond to rising equity market conditions as quickly as another fund that invests primarily in equity securities. In addition, to maintain compliance with the risk parameters, the Fund may need to liquidate a position, or forego an investment that could have otherwise contributed to Fund performance. Under certain circumstances, the Capital Protection Agreement may require that all of the Fund’s assets be fully allocated to the Protection Component, thus limiting the upside potential for Fund returns during this period. The use of the risk allocation methodology may also impact the Fund’s performance in the event that it does not work as intended, potentially subjecting the Fund to additional expenses as a result of increased trading or allocating a larger portion of the Fund’s assets than necessary to either the Equity Component or Protection Component. Because the Fund may reallocate its assets between and within the Equity Component and the Protection Component as frequently as daily, the Fund’s reallocation may cause it to experience an increase in its portfolio turnover rate resulting in higher costs, which may have a negative effect on the Fund’s performance, particularly during periods of relative instability in equity markets. The Fund’s payment of the capital protection fee to the Capital Protection Provider may also result in the Fund underperforming its primary benchmark and/or other similarly situated growth funds that do not pay a protection fee. Capital Protection Termination Risk. There is a risk that the Protection could terminate. The terms and conditions of the Capital Protection Agreement are designed to protect against certain market risks inherent in any equity investment. It does not protect against certain actions or omissions that constitute gross negligence, fraud, bad faith, willful misconduct, or a criminal act on the part of the Fund, Janus Capital or certain key employees of Janus Capital, or the Fund’s custodian, that negatively impacts a share class’ NAV. Such events will result in the termination of the Protection without any obligation by the Capital Protection Provider, and therefore by the Parent Guarantor, to make any payment to the Fund. The Fund will liquidate in these events, and shareholders will receive the then-current NAV of their share class, which could be below the Protected NAV. Neither the Fund nor Janus Capital is obligated to make any payment to the Fund or cover any shortfall. Therefore, in the event that the Protection is terminated as a result of such events, you could lose money as a result of the Fund losing the Protection under the Capital Protection Agreement, including amounts that would have otherwise been protected. This means that you could receive less than 80% of your investment. Early Termination Events Risk. While the Capital Protection Agreement has an initial 10-year term that may be extended, there is a risk that the Capital Protection Agreement could terminate earlier under various scenarios at the option of the Capital Protection Provider, which are considered Early Termination Events. In such events, the Capital Protection Provider will be obligated to make the payment of the Settlement Amount, if due, to the Fund and the Fund will liquidate. Shareholders receive the higher of their Protected NAV or the then-current NAV for their share class, which will include any Settlement Amount due to the Fund. Examples of “Early Termination Events” include, but not are not limited to (1) if the Fund, Janus Capital, or the Fund’s custodian, fails to comply with certain terms and conditions of the Capital Protection Agreement, including the failure to reallocate Fund assets when such assets fall outside the specified risk parameters, or (2) if the aggregate value of the Fund’s shares outstanding results in the Protection exceeding the Maximum Settlement Amount. The Fund is also expected to liquidate and the Capital Protection Agreement will terminate if, pursuant to the terms of the Capital Protection Agreement, the Protection is triggered. In addition, to the extent that the introduction of laws or a change of law, in each case, not known as of the date of the Capital Protection Agreement results in a new or increased cost of capital or collateral for the Capital Protection Provider or its parent company, the Fund’s Board of Trustees will make a determination whether to approve the Fund paying such increased costs to the Capital Protection Provider or to terminate the Capital Protection Agreement. Only shareholders who hold their shares on the Termination Date are covered by the Protection. Shareholders who redeem prior to the Termination Date receive the then-current NAV which will be higher than the Protected NAV for their share class and will not include any payment of the Protection. Maximum Settlement Amount Risk. The Capital Protection Agreement currently covers the outstanding shares of each class of shares offered by the Fund having an aggregate protected amount up to an initial value of $1.5 billion. If the Maximum Settlement Amount exceeds $1.5 billion without any additional coverage being extended to the Fund, the Capital Protection Provider will not be liable for any Settlement Amount payment in excess of $1.5 billion. None of the Fund, Janus Capital, or any affiliate thereof, will be responsible for any portion of the Settlement Amount, including any amounts which may exceed the Maximum Settlement Amount. Therefore, although the Protection applies, you could lose money to the extent the Aggregate Shortfall Amount exceeds the Maximum Settlement Amount including amounts that would have otherwise been protected. This means that you could receive less than 80% of your investment. In any event, as the Fund’s assets grow, the Fund intends to take such actions as may be deemed necessary, including limiting purchases, to limit the Aggregate Shortfall Amount to a level so that it does not exceed the Maximum Settlement Amount, but there is no guarantee that such efforts will be successful. There is no guarantee that the Capital Protection Provider will agree to extend coverage beyond $1.5 billion. Liquidation Risk. Although the risk allocation methodology is designed so that the NAV of each share class does not fall below its Protected NAV, there is the possibility that the risk allocation methodology may not work as designed or redemptions, particularly a large redemption, may impact the allocation process, and the NAV of any share class falls below its Protected NAV. If this happens, it is expected that the Fund will liquidate as soon as possible following the event and receive payment of the Settlement Amount from the Capital Protection Provider. The NAV of one share class falling below its Protected NAV will result in the Protection being triggered and, as a result, the liquidation of the entire Fund, even though the NAV of one or more other share classes remains at or above its Protected NAV. Other events described in this Prospectus may, at the discretion of the Fund or Capital Protection Provider, as applicable, also terminate the Capital Protection Agreement resulting in payment of the Settlement Amount and liquidation of the Fund. In the event the Protection is triggered and the Fund begins the liquidation process, no other purchases will be permitted, and the payment of redemption proceeds will be suspended, likely from the day the Protection is triggered; shareholders will receive the higher of the then-current NAV per share or the Protected NAV per share for their share class, which will include any Settlement Amount due to the Fund. Redemptions are taxable events. This Prospectus serves as advance notice to shareholders of any rejection of purchases, suspension of the payment of redemption proceeds, and liquidation of the Fund. In the event that the Capital Protection Agreement is terminated and the Fund begins the liquidation process, Janus Capital will make such information available at janus.com/advisor/mutual-funds or janus.com/allfunds for shareholders of Class D Shares. Notice of the Fund liquidation will otherwise be made when you receive your redemption proceeds. For illustrative purposes to understand a scenario where the Protection is triggered and the Fund proceeds to liquidation, see below: Protected NAV across all share classes is $10.00 –
Opportunity Cost Risk. It is possible that under the terms of the Capital Protection Agreement, the Fund’s allocation to the Equity Component could drop to a low level or be eliminated altogether, especially during periods of heightened volatility in equity markets. This would reduce the Fund’s ability to participate in upward equity market movements, and therefore, represents loss of opportunity compared to a fund that is fully invested in equity securities. Counterparty Risk (Capital Protection Provider and its Parent Company). A shareholder’s ability to receive the Protected NAV from the Fund is dependent on the Fund’s ability to collect the Settlement Amount from the Capital Protection Provider pursuant to the terms of the Capital Protection Agreement or from the Capital Protection Provider’s parent under a separate parent guaranty. Fund transactions involving a counterparty, such as the Capital Protection Provider, are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. As such, the Fund’s ability to benefit from the Protection may depend on the Capital Protection Provider’s, as well as its parent company’s, financial condition. As an added measure of protection, BNP Paribas, the parent company of the Capital Protection Provider, has issued an absolute, irrevocable and continuing guaranty pursuant to which it guarantees any and all financial obligations of the Capital Protection Provider under the Capital Protection Agreement. There is, however, a risk that the Capital Protection Provider’s parent company may not fulfill its obligations under the guaranty it has issued. Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or multiple companies in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. The Fund’s use of the risk allocation methodology is intended to protect against significant downward movement of the NAV per share for a share class, particularly in times of heightened volatility in the equity markets, but the methodology may not protect the Fund if equity markets take a sudden and/or significant fall. Growth Securities Risk. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. The price of a “growth” security may be impacted if the company does not realize its anticipated potential or if there is a shift in the market to favor other types of securities. Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations to the Fund. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited. Foreign Exposure Risk. The Fund may have significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. A market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries. Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities are exposed to a number of additional risks, which may result from less government supervision and regulation of business and industry practices, stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. Portfolio Turnover Risk. Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders. The risk allocation methodology utilized by the Fund may increase the level of portfolio turnover. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. |

| Principal Investment Strategies | jif277751_PrincipalInvestmentStrategiesAbstract | Â | ||||||
| Strategy [Heading] | rr_StrategyHeading | PRINCIPAL INVESTMENT STRATEGIES | ||||||
| Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund seeks growth of capital to the extent consistent with maintaining protection against significant downside movement of the net asset value (“NAV”) per share of each share class of the Fund. Specifically, the portfolio manager manages the Fund’s assets in an effort to ensure that the NAV for each share class will not fall below 80% of the highest NAV attained separately by each share class during the life of the Fund, reduced for dividends, distributions, any extraordinary expenses, and certain extraordinary items (for each share class, the “Protected NAV”). A reduction of the NAV can be described further by using distributions as an example. In the event the Fund declares dividends from net investment income and capital gains distributions, which normally occurs in December, the Protected NAV per share will be adjusted down so that the relative protection level remains at the level in place prior to the distribution. While the Protected NAV per share is changed as a result of a distribution, the protected value of your account balance does not change, assuming you reinvest your distribution. For example, on a day the highest NAV per share of a share class is reached at $11.00, the Protected NAV per share is set at $8.80, which is 80% of the highest NAV per share. When the highest NAV per share increases to $12.50, the Protected NAV per share is set at $10.00, which is 80% of the highest NAV. On a day the NAV per share is $12.00, the Fund declares a per share distribution of $1.00. The result of the distribution is that the NAV per share is reduced from $12.00 to $11.00. The Protected NAV per share is also reduced so that the Protected NAV per share is the same relative to the post-distribution NAV per share of $11.00 as it was to the pre-distribution NAV per share of $12.00. The Protected NAV per share of $10.00 was 83.3% of the pre-distribution NAV per share of $12.00 per share and the post-distribution Protected NAV per share is adjusted to $9.17, which is 83.3% of the post-distribution NAV per share. Additional information regarding how the Protected NAV per share is adjusted following a distribution is included in Appendix A. The reduction for extraordinary expenses and extraordinary items from the NAV would have a similar result. In general, protection for the Fund means, as the NAV per share for a share class rises, the Protected NAV also rises and becomes the new Protected NAV regardless of whether the share class’ NAV per share subsequently declines or fails to achieve a new high threshold. However, as a share class’ NAV declines towards the Protected NAV, more of the Fund’s assets will be comprised of cash and other investments, called the “Protection Component,” as further described below. In order to minimize the effect of equity market volatility on the NAV per share for a share class, the Fund allocates its portfolio assets between two investment components. Through its first component, the “Equity Component,” the Fund seeks to achieve growth of capital by investing primarily in common stocks selected for their growth potential. Although the Fund may invest in companies of any size, it generally invests in larger, more established companies. The Equity Component may also consist of derivatives such as options and futures. Through its second component, the “Protection Component,” the Fund seeks to limit downside risk by investing in cash and other investments including, but not limited to, money market instruments, U.S. Treasuries, and other equity market risk reducing instruments, such as short index futures. Due to equity market conditions and the Fund’s overall risk profile, the amount of Fund assets allocated to the Protection Component may, at times, be significant. The Fund’s allocation between the Equity Component and the Protection Component will vary over time. Up to 100% of assets may be allocated to either component. The portfolio manager applies a “bottom up” approach in choosing common stock investments for the Equity Component. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. As part of the Equity Component, the Fund may invest in foreign equity and debt securities, which may include investments in emerging markets. As noted above, the Fund may also invest the assets of either component in derivatives, which are instruments that have a value derived from an underlying asset, such as stocks, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) including, but not limited to, futures and over-the-counter and exchange-traded put or call options for various purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. In an effort to protect against significant downward movement of the NAV per share for a share class, the Fund has entered into a Capital Protection Agreement with BNP Paribas Prime Brokerage, Inc., a U.S. registered broker-dealer and a member of FINRA (the “Capital Protection Provider”). Pursuant to the Capital Protection Agreement, under certain conditions, the Capital Protection Provider will provide capital protection to the Fund (the “Protection”) in the event that any share class’ NAV per share falls below its Protected NAV. Any one share class falling below its Protected NAV will trigger the Protection and liquidation of the Fund and each of its share classes, regardless of whether the NAV of any other share class is above its Protected NAV. The Capital Protection Provider has agreed to initially extend $1.5 billion in aggregate protection coverage to the Fund with such amount being reviewed periodically to determine whether additional coverage is necessary or available to support the Fund’s rising assets (the “Maximum Settlement Amount”). As such, under the Capital Protection Agreement, the NAV of each share class is protected to at least the Protected NAV for such share class, subject to an aggregate limit on the overall payout to the Fund of the Maximum Settlement Amount. In the event that the Protection is triggered, meaning at least one share class’ NAV is below its Protected NAV, the Capital Protection Provider is obligated to pay the Fund the “Settlement Amount,” which is the lesser of (i) the sum of the shortfall amounts per share class (the “Aggregate Shortfall Amount”) and (ii) the Maximum Settlement Amount. For each share class, the shortfall amount is calculated by first establishing, among those share classes that have a NAV below their Protected NAV, the highest percentage difference among all of those share classes between the Protected NAV per share and the then-current NAV per share, and applying that percentage to each Fund share class’ then-current NAV per share. The Aggregate Shortfall Amount is thus allocated on a pro rata basis to each share class. In order to comply with the terms of the Capital Protection Agreement, the Fund must provide certain information to the Capital Protection Provider and the Fund’s portfolio manager is required to manage the Fund within certain risk parameters as identified on a daily basis by the Capital Protection Provider based on a risk allocation methodology. This risk allocation methodology factors in, among other things, market volatility, the Fund’s exposure to industries, sectors, or countries, and liquidity of the Fund’s holdings. In general, as equity markets are rising, the Fund’s allocation to the Equity Component will rise with a goal of taking advantage of any potential future market increase, and as equity markets are falling, the Fund’s portfolio manager will allocate more of the Fund’s assets to the Protection Component in an effort to protect the Fund from a potential ongoing decrease in the market. The Fund’s asset allocation will vary over time depending on equity market conditions and the Fund’s portfolio composition. As a result, the Fund’s allocation to each investment component could change as frequently as daily, resulting in a higher portfolio turnover rate than other mutual funds. The Capital Protection Agreement has an initial term of 10 years and may be extended for additional 10-year terms by mutual agreement of the Fund and the Capital Protection Provider. Under certain circumstances, the Capital Protection Agreement may be terminated prior to the expiration of any effective term, which in any case would become the “Termination Date.” Only shareholders who hold their shares on such Termination Date will be covered by the Protection. In the event of such termination of the Capital Protection Agreement, the Fund will terminate and liquidate and the Capital Protection Provider will pay the Fund any amounts due related to the Protection. This Prospectus serves as advance notice to you of any such liquidation. There are limited circumstances in which the Protection also terminates on the Termination Date, meaning the Capital Protection Provider is not obligated to pay any amounts to the Fund even where the NAV of a share class is below its Protected NAV. These circumstances are described further below under “Principal Investment Risks” as “Capital Protection Termination Risk.” It is important to understand that the Capital Protection Agreement is a financial product that is intended to protect the Fund against significant market declines and does not in any way constitute any form of insurance. In addition, the Capital Protection Provider is not an insurance company or an insurance provider, nor is it acting as an adviser or subadviser for the Fund. |

| Principal Investment Risks | jif277751_PrincipalInvestmentRisksAbstract | Â | ||||||
| Risk [Heading] | rr_RiskHeading | PRINCIPAL INVESTMENT RISKS | ||||||
| Risk Narrative [Text Block] | rr_RiskNarrativeTextBlock | The biggest risk is that the Fund’s returns will vary, and you could lose money, despite the Capital Protection Agreement. Common stocks tend to be more volatile than many other investment choices. Because the NAV per share for a share class is protected to at least 80%, and not 100%, of its highest attained NAV since the inception of the share class (as reduced to account for dividends, distributions, any extraordinary expenses, and certain extraordinary items), it is possible that in the event that equity markets fall, you could lose money, even if the Protection is triggered. In addition, if the Capital Protection Agreement does not work as intended or has been terminated, you could lose money. Because the Protected NAV is reduced by dividends, distributions, any extraordinary expenses, and certain extraordinary items, the amount of Protection could be less than 80% of the highest attained NAV for your class of shares, meaning the Protected NAV does not become a static number that only increases. To the extent that the protected amount owed to the Fund exceeds the Maximum Settlement Amount ($1.5 billion), neither the Fund nor Janus Capital will cover any shortfall amount, so you could lose money including amounts that would have otherwise been protected. The Protected NAV for each share class will be posted on the Janus websites at janus.com/allfunds, or janus.com/advisor/mutual-funds for share classes other than Class D Shares. Any change to the Protected NAV will be updated within one business day. Because any one share class falling below its Protected NAV can alone trigger the Protection and liquidation of the Fund, shareholders should review the Protected NAV for each share class prior to purchasing shares of this Fund, keeping in mind that each share class has different fees and expenses that impact the NAV. Allocation Risk. Because there are risk parameters within which the portfolio manager must manage the Fund’s assets in order to maintain the Protection, the Fund’s ability to take certain investment actions that the portfolio manager might otherwise take may be limited. More specifically, complying with the provisions of the Capital Protection Agreement may impact the Fund’s allocation of assets to and within the Equity Component during the life of the Fund and/or affect the portfolio manager’s ability to respond to changing equity market conditions. This could limit the Fund’s ability to capture certain market gains when the allocations are more heavily weighted to the Protection Component. Conversely, as equity markets are rising or displaying signs of relative stability, the Fund may have more of the portfolio weighted towards assets considered to have higher risk which could increase the potential for loss of return for the Fund. Generally, the risk parameters may lead the portfolio manager to take certain investment actions that he otherwise would not take when allocating the Fund’s assets between and within the Equity Component and the Protection Component. This allocation process can have an adverse effect on the performance of the Fund, especially during periods of increased equity market volatility. The risk allocation methodology is designed so that the NAV of each share class does not fall below its Protected NAV and, if successful, protection payments are not triggered. It is possible, however, that the risk allocation methodology may not work as designed or intended and may cause the Fund to trigger the Protection, resulting in the termination of the Fund. In addition, the allocation of the Fund’s assets between and within the Equity Component and the Protection Component may result in a high portfolio turnover rate and additional transaction costs, such as brokerage commissions, which can impact the Fund’s returns. Because the portfolio manager allocates the Fund’s assets between and within the Equity Component and Protection Component daily according to a risk allocation methodology, there is the risk that a sudden intraday market drop may occur before the Fund’s Equity Component exposure can be reduced. Additionally, if the Fund fails to allocate its assets according to the risk allocation methodology, the Capital Protection Provider will have the option to terminate the Capital Protection Agreement, resulting in the Fund allocating 100% of its assets solely to cash and the liquidation of the Fund. Under these circumstances, the Capital Protection Provider will pay any amounts it is obligated to pay to the Fund. Market Underperformance Risk. The Fund’s use of the risk allocation methodology and the resulting allocation between and within the Equity Component and the Protection Component may cause the Fund to underperform its primary benchmark and/or other similarly situated growth funds. This underperformance may be a result of the portfolio manager’s inability to reallocate Fund assets to respond to rising equity market conditions as quickly as another fund that invests primarily in equity securities. In addition, to maintain compliance with the risk parameters, the Fund may need to liquidate a position, or forego an investment that could have otherwise contributed to Fund performance. Under certain circumstances, the Capital Protection Agreement may require that all of the Fund’s assets be fully allocated to the Protection Component, thus limiting the upside potential for Fund returns during this period. The use of the risk allocation methodology may also impact the Fund’s performance in the event that it does not work as intended, potentially subjecting the Fund to additional expenses as a result of increased trading or allocating a larger portion of the Fund’s assets than necessary to either the Equity Component or Protection Component. Because the Fund may reallocate its assets between and within the Equity Component and the Protection Component as frequently as daily, the Fund’s reallocation may cause it to experience an increase in its portfolio turnover rate resulting in higher costs, which may have a negative effect on the Fund’s performance, particularly during periods of relative instability in equity markets. The Fund’s payment of the capital protection fee to the Capital Protection Provider may also result in the Fund underperforming its primary benchmark and/or other similarly situated growth funds that do not pay a protection fee. Capital Protection Termination Risk. There is a risk that the Protection could terminate. The terms and conditions of the Capital Protection Agreement are designed to protect against certain market risks inherent in any equity investment. It does not protect against certain actions or omissions that constitute gross negligence, fraud, bad faith, willful misconduct, or a criminal act on the part of the Fund, Janus Capital or certain key employees of Janus Capital, or the Fund’s custodian, that negatively impacts a share class’ NAV. Such events will result in the termination of the Protection without any obligation by the Capital Protection Provider, and therefore by the Parent Guarantor, to make any payment to the Fund. The Fund will liquidate in these events, and shareholders will receive the then-current NAV of their share class, which could be below the Protected NAV. Neither the Fund nor Janus Capital is obligated to make any payment to the Fund or cover any shortfall. Therefore, in the event that the Protection is terminated as a result of such events, you could lose money as a result of the Fund losing the Protection under the Capital Protection Agreement, including amounts that would have otherwise been protected. This means that you could receive less than 80% of your investment. Early Termination Events Risk. While the Capital Protection Agreement has an initial 10-year term that may be extended, there is a risk that the Capital Protection Agreement could terminate earlier under various scenarios at the option of the Capital Protection Provider, which are considered Early Termination Events. In such events, the Capital Protection Provider will be obligated to make the payment of the Settlement Amount, if due, to the Fund and the Fund will liquidate. Shareholders receive the higher of their Protected NAV or the then-current NAV for their share class, which will include any Settlement Amount due to the Fund. Examples of “Early Termination Events” include, but not are not limited to (1) if the Fund, Janus Capital, or the Fund’s custodian, fails to comply with certain terms and conditions of the Capital Protection Agreement, including the failure to reallocate Fund assets when such assets fall outside the specified risk parameters, or (2) if the aggregate value of the Fund’s shares outstanding results in the Protection exceeding the Maximum Settlement Amount. The Fund is also expected to liquidate and the Capital Protection Agreement will terminate if, pursuant to the terms of the Capital Protection Agreement, the Protection is triggered. In addition, to the extent that the introduction of laws or a change of law, in each case, not known as of the date of the Capital Protection Agreement results in a new or increased cost of capital or collateral for the Capital Protection Provider or its parent company, the Fund’s Board of Trustees will make a determination whether to approve the Fund paying such increased costs to the Capital Protection Provider or to terminate the Capital Protection Agreement. Only shareholders who hold their shares on the Termination Date are covered by the Protection. Shareholders who redeem prior to the Termination Date receive the then-current NAV which will be higher than the Protected NAV for their share class and will not include any payment of the Protection. Maximum Settlement Amount Risk. The Capital Protection Agreement currently covers the outstanding shares of each class of shares offered by the Fund having an aggregate protected amount up to an initial value of $1.5 billion. If the Maximum Settlement Amount exceeds $1.5 billion without any additional coverage being extended to the Fund, the Capital Protection Provider will not be liable for any Settlement Amount payment in excess of $1.5 billion. None of the Fund, Janus Capital, or any affiliate thereof, will be responsible for any portion of the Settlement Amount, including any amounts which may exceed the Maximum Settlement Amount. Therefore, although the Protection applies, you could lose money to the extent the Aggregate Shortfall Amount exceeds the Maximum Settlement Amount including amounts that would have otherwise been protected. This means that you could receive less than 80% of your investment. In any event, as the Fund’s assets grow, the Fund intends to take such actions as may be deemed necessary, including limiting purchases, to limit the Aggregate Shortfall Amount to a level so that it does not exceed the Maximum Settlement Amount, but there is no guarantee that such efforts will be successful. There is no guarantee that the Capital Protection Provider will agree to extend coverage beyond $1.5 billion. Liquidation Risk. Although the risk allocation methodology is designed so that the NAV of each share class does not fall below its Protected NAV, there is the possibility that the risk allocation methodology may not work as designed or redemptions, particularly a large redemption, may impact the allocation process, and the NAV of any share class falls below its Protected NAV. If this happens, it is expected that the Fund will liquidate as soon as possible following the event and receive payment of the Settlement Amount from the Capital Protection Provider. The NAV of one share class falling below its Protected NAV will result in the Protection being triggered and, as a result, the liquidation of the entire Fund, even though the NAV of one or more other share classes remains at or above its Protected NAV. Other events described in this Prospectus may, at the discretion of the Fund or Capital Protection Provider, as applicable, also terminate the Capital Protection Agreement resulting in payment of the Settlement Amount and liquidation of the Fund. In the event the Protection is triggered and the Fund begins the liquidation process, no other purchases will be permitted, and the payment of redemption proceeds will be suspended, likely from the day the Protection is triggered; shareholders will receive the higher of the then-current NAV per share or the Protected NAV per share for their share class, which will include any Settlement Amount due to the Fund. Redemptions are taxable events. This Prospectus serves as advance notice to shareholders of any rejection of purchases, suspension of the payment of redemption proceeds, and liquidation of the Fund. In the event that the Capital Protection Agreement is terminated and the Fund begins the liquidation process, Janus Capital will make such information available at janus.com/allfunds, or janus.com/advisor/mutual-funds for share classes other than Class D Shares. Notice of the Fund liquidation will otherwise be made when you receive your redemption proceeds. For illustrative purposes to understand a scenario where the Protection is triggered and the Fund proceeds to liquidation, see below: Protected NAV across all share classes is $10.00 –
Opportunity Cost Risk. It is possible that under the terms of the Capital Protection Agreement, the Fund’s allocation to the Equity Component could drop to a low level or be eliminated altogether, especially during periods of heightened volatility in equity markets. This would reduce the Fund’s ability to participate in upward equity market movements, and therefore, represents loss of opportunity compared to a fund that is fully invested in equity securities. Counterparty Risk (Capital Protection Provider and its Parent Company). A shareholder’s ability to receive the Protected NAV from the Fund is dependent on the Fund’s ability to collect the Settlement Amount from the Capital Protection Provider pursuant to the terms of the Capital Protection Agreement or from the Capital Protection Provider’s parent under a separate parent guaranty. Fund transactions involving a counterparty, such as the Capital Protection Provider, are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. As such, the Fund’s ability to benefit from the Protection may depend on the Capital Protection Provider’s, as well as its parent company’s, financial condition. As an added measure of protection, BNP Paribas, the parent company of the Capital Protection Provider, has issued an absolute, irrevocable and continuing guaranty pursuant to which it guarantees any and all financial obligations of the Capital Protection Provider under the Capital Protection Agreement. There is, however, a risk that the Capital Protection Provider’s parent company may not fulfill its obligations under the guaranty it has issued. Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or multiple companies in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. The Fund’s use of the risk allocation methodology is intended to protect against significant downward movement of the NAV per share for a share class, particularly in times of heightened volatility in the equity markets, but the methodology may not protect the Fund if equity markets take a sudden and/or significant fall. Growth Securities Risk. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. The price of a “growth” security may be impacted if the company does not realize its anticipated potential or if there is a shift in the market to favor other types of securities. Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations to the Fund. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited. Foreign Exposure Risk. The Fund may have significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. A market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries. Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities are exposed to a number of additional risks, which may result from less government supervision and regulation of business and industry practices, stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. Portfolio Turnover Risk. Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders. The risk allocation methodology utilized by the Fund may increase the level of portfolio turnover. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. |

| FUND SUMMARY Janus Protected Series – Growth | |||||||||||||||||||||||||
| INVESTMENT OBJECTIVE | |||||||||||||||||||||||||
| Janus Protected Series – Growth seeks long-term growth of capital and capital preservation. | |||||||||||||||||||||||||
| FEES AND EXPENSES OF THE FUND | |||||||||||||||||||||||||
| This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund. There are no shareholder fees (fees paid directly from your investment). | |||||||||||||||||||||||||
| ANNUAL FUND OPERATING EXPENSES (expenses that you pay each year as a percentage of the value of your investment) | |||||||||||||||||||||||||
|
|||||||||||||||||||||||||
| EXAMPLE: | |||||||||||||||||||||||||
| The following Example is based on expenses without waivers. The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. | |||||||||||||||||||||||||
| The Example assumes that you invest $10,000 in the Fund for the time periods indicated, reinvest all dividends and distributions, and then redeem all of your Shares at the end of each period. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses, including the maximum amount of the capital protection fee, without waivers, remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | |||||||||||||||||||||||||
|
|||||||||||||||||||||||||
| Portfolio Turnover: | |||||||||||||||||||||||||
| The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. | |||||||||||||||||||||||||
| PRINCIPAL INVESTMENT STRATEGIES | |||||||||||||||||||||||||
The Fund seeks growth of capital to the extent consistent with maintaining protection against significant downside movement of the net asset value (“NAV”) per share of each share class of the Fund. Specifically, the portfolio manager manages the Fund’s assets in an effort to ensure that the NAV for each share class will not fall below 80% of the highest NAV attained separately by each share class during the life of the Fund, reduced for dividends, distributions, any extraordinary expenses, and certain extraordinary items (for each share class, the “Protected NAV”). A reduction of the NAV can be described further by using distributions as an example. In the event the Fund declares dividends from net investment income and capital gains distributions, which normally occurs in December, the Protected NAV per share will be adjusted down so that the relative protection level remains at the level in place prior to the distribution. While the Protected NAV per share is changed as a result of a distribution, the protected value of your account balance does not change, assuming you reinvest your distribution. For example, on a day the highest NAV per share of a share class is reached at $11.00, the Protected NAV per share is set at $8.80, which is 80% of the highest NAV per share. When the highest NAV per share increases to $12.50, the Protected NAV per share is set at $10.00, which is 80% of the highest NAV. On a day the NAV per share is $12.00, the Fund declares a per share distribution of $1.00. The result of the distribution is that the NAV per share is reduced from $12.00 to $11.00. The Protected NAV per share is also reduced so that the Protected NAV per share is the same relative to the post-distribution NAV per share of $11.00 as it was to the pre-distribution NAV per share of $12.00. The Protected NAV per share of $10.00 was 83.3% of the pre-distribution NAV per share of $12.00 per share and the post-distribution Protected NAV per share is adjusted to $9.17, which is 83.3% of the post-distribution NAV per share. Additional information regarding how the Protected NAV per share is adjusted following a distribution is included in Appendix A. The reduction for extraordinary expenses and extraordinary items from the NAV would have a similar result. In general, protection for the Fund means, as the NAV per share for a share class rises, the Protected NAV also rises and becomes the new Protected NAV regardless of whether the share class’ NAV per share subsequently declines or fails to achieve a new high threshold. However, as a share class’ NAV declines towards the Protected NAV, more of the Fund’s assets will be comprised of cash and other investments, called the “Protection Component,” as further described below. In order to minimize the effect of equity market volatility on the NAV per share for a share class, the Fund allocates its portfolio assets between two investment components. Through its first component, the “Equity Component,” the Fund seeks to achieve growth of capital by investing primarily in common stocks selected for their growth potential. Although the Fund may invest in companies of any size, it generally invests in larger, more established companies. The Equity Component may also consist of derivatives such as options and futures. Through its second component, the “Protection Component,” the Fund seeks to limit downside risk by investing in cash and other investments including, but not limited to, money market instruments, U.S. Treasuries, and other equity market risk reducing instruments, such as short index futures. Due to equity market conditions and the Fund’s overall risk profile, the amount of Fund assets allocated to the Protection Component may, at times, be significant. The Fund’s allocation between the Equity Component and the Protection Component will vary over time. Up to 100% of assets may be allocated to either component. The portfolio manager applies a “bottom up” approach in choosing common stock investments for the Equity Component. In other words, the portfolio manager looks at companies one at a time to determine if a company is an attractive investment opportunity and if it is consistent with the Fund’s investment policies. As part of the Equity Component, the Fund may invest in foreign equity and debt securities, which may include investments in emerging markets. As noted above, the Fund may also invest the assets of either component in derivatives, which are instruments that have a value derived from an underlying asset, such as stocks, bonds, commodities, currencies, interest rates, or market indices, as substitutes for securities in which the Fund invests. The Fund may invest in derivative instruments (by taking long and/or short positions) including, but not limited to, futures and over-the-counter and exchange-traded put or call options for various purposes, including hedging, to increase or decrease the Fund’s exposure to a particular market, to manage or adjust the risk profile of the Fund related to an investment or currency exposure, and to earn income and enhance returns. The Fund’s exposure to derivatives will vary, is not limited to those derivatives listed, and could be significant at times. In an effort to protect against significant downward movement of the NAV per share for a share class, the Fund has entered into a Capital Protection Agreement with BNP Paribas Prime Brokerage, Inc., a U.S. registered broker-dealer and a member of FINRA (the “Capital Protection Provider”). Pursuant to the Capital Protection Agreement, under certain conditions, the Capital Protection Provider will provide capital protection to the Fund (the “Protection”) in the event that any share class’ NAV per share falls below its Protected NAV. Any one share class falling below its Protected NAV will trigger the Protection and liquidation of the Fund and each of its share classes, regardless of whether the NAV of any other share class is above its Protected NAV. The Capital Protection Provider has agreed to initially extend $1.5 billion in aggregate protection coverage to the Fund with such amount being reviewed periodically to determine whether additional coverage is necessary or available to support the Fund’s rising assets (the “Maximum Settlement Amount”). As such, under the Capital Protection Agreement, the NAV of each share class is protected to at least the Protected NAV for such share class, subject to an aggregate limit on the overall payout to the Fund of the Maximum Settlement Amount. In the event that the Protection is triggered, meaning at least one share class’ NAV is below its Protected NAV, the Capital Protection Provider is obligated to pay the Fund the “Settlement Amount,” which is the lesser of (i) the sum of the shortfall amounts per share class (the “Aggregate Shortfall Amount”) and (ii) the Maximum Settlement Amount. For each share class, the shortfall amount is calculated by first establishing, among those share classes that have a NAV below their Protected NAV, the highest percentage difference among all of those share classes between the Protected NAV per share and the then-current NAV per share, and applying that percentage to each Fund share class’ then-current NAV per share. The Aggregate Shortfall Amount is thus allocated on a pro rata basis to each share class. In order to comply with the terms of the Capital Protection Agreement, the Fund must provide certain information to the Capital Protection Provider and the Fund’s portfolio manager is required to manage the Fund within certain risk parameters as identified on a daily basis by the Capital Protection Provider based on a risk allocation methodology. This risk allocation methodology factors in, among other things, market volatility, the Fund’s exposure to industries, sectors, or countries, and liquidity of the Fund’s holdings. In general, as equity markets are rising, the Fund’s allocation to the Equity Component will rise with a goal of taking advantage of any potential future market increase, and as equity markets are falling, the Fund’s portfolio manager will allocate more of the Fund’s assets to the Protection Component in an effort to protect the Fund from a potential ongoing decrease in the market. The Fund’s asset allocation will vary over time depending on equity market conditions and the Fund’s portfolio composition. As a result, the Fund’s allocation to each investment component could change as frequently as daily, resulting in a higher portfolio turnover rate than other mutual funds. The Capital Protection Agreement has an initial term of 10 years and may be extended for additional 10-year terms by mutual agreement of the Fund and the Capital Protection Provider. Under certain circumstances, the Capital Protection Agreement may be terminated prior to the expiration of any effective term, which in any case would become the “Termination Date.” Only shareholders who hold their shares on such Termination Date will be covered by the Protection. In the event of such termination of the Capital Protection Agreement, the Fund will terminate and liquidate and the Capital Protection Provider will pay the Fund any amounts due related to the Protection. This Prospectus serves as advance notice to you of any such liquidation. There are limited circumstances in which the Protection also terminates on the Termination Date, meaning the Capital Protection Provider is not obligated to pay any amounts to the Fund even where the NAV of a share class is below its Protected NAV. These circumstances are described further below under “Principal Investment Risks” as “Capital Protection Termination Risk.” It is important to understand that the Capital Protection Agreement is a financial product that is intended to protect the Fund against significant market declines and does not in any way constitute any form of insurance. In addition, the Capital Protection Provider is not an insurance company or an insurance provider, nor is it acting as an adviser or subadviser for the Fund. |

| PRINCIPAL INVESTMENT RISKS | |||||||||||||||||||||||||
The biggest risk is that the Fund’s returns will vary, and you could lose money, despite the Capital Protection Agreement. Common stocks tend to be more volatile than many other investment choices. Because the NAV per share for a share class is protected to at least 80%, and not 100%, of its highest attained NAV since the inception of the share class (as reduced to account for dividends, distributions, any extraordinary expenses, and certain extraordinary items), it is possible that in the event that equity markets fall, you could lose money, even if the Protection is triggered. In addition, if the Capital Protection Agreement does not work as intended or has been terminated, you could lose money. Because the Protected NAV is reduced by dividends, distributions, any extraordinary expenses, and certain extraordinary items, the amount of Protection could be less than 80% of the highest attained NAV for your class of shares, meaning the Protected NAV does not become a static number that only increases. To the extent that the protected amount owed to the Fund exceeds the Maximum Settlement Amount ($1.5 billion), neither the Fund nor Janus Capital will cover any shortfall amount, so you could lose money including amounts that would have otherwise been protected. The Protected NAV for each share class will be posted on the Janus websites at janus.com/allfunds, or janus.com/advisor/mutual-funds for share classes other than Class D Shares. Any change to the Protected NAV will be updated within one business day. Because any one share class falling below its Protected NAV can alone trigger the Protection and liquidation of the Fund, shareholders should review the Protected NAV for each share class prior to purchasing shares of this Fund, keeping in mind that each share class has different fees and expenses that impact the NAV. Allocation Risk. Because there are risk parameters within which the portfolio manager must manage the Fund’s assets in order to maintain the Protection, the Fund’s ability to take certain investment actions that the portfolio manager might otherwise take may be limited. More specifically, complying with the provisions of the Capital Protection Agreement may impact the Fund’s allocation of assets to and within the Equity Component during the life of the Fund and/or affect the portfolio manager’s ability to respond to changing equity market conditions. This could limit the Fund’s ability to capture certain market gains when the allocations are more heavily weighted to the Protection Component. Conversely, as equity markets are rising or displaying signs of relative stability, the Fund may have more of the portfolio weighted towards assets considered to have higher risk which could increase the potential for loss of return for the Fund. Generally, the risk parameters may lead the portfolio manager to take certain investment actions that he otherwise would not take when allocating the Fund’s assets between and within the Equity Component and the Protection Component. This allocation process can have an adverse effect on the performance of the Fund, especially during periods of increased equity market volatility. The risk allocation methodology is designed so that the NAV of each share class does not fall below its Protected NAV and, if successful, protection payments are not triggered. It is possible, however, that the risk allocation methodology may not work as designed or intended and may cause the Fund to trigger the Protection, resulting in the termination of the Fund. In addition, the allocation of the Fund’s assets between and within the Equity Component and the Protection Component may result in a high portfolio turnover rate and additional transaction costs, such as brokerage commissions, which can impact the Fund’s returns. Because the portfolio manager allocates the Fund’s assets between and within the Equity Component and Protection Component daily according to a risk allocation methodology, there is the risk that a sudden intraday market drop may occur before the Fund’s Equity Component exposure can be reduced. Additionally, if the Fund fails to allocate its assets according to the risk allocation methodology, the Capital Protection Provider will have the option to terminate the Capital Protection Agreement, resulting in the Fund allocating 100% of its assets solely to cash and the liquidation of the Fund. Under these circumstances, the Capital Protection Provider will pay any amounts it is obligated to pay to the Fund. Market Underperformance Risk. The Fund’s use of the risk allocation methodology and the resulting allocation between and within the Equity Component and the Protection Component may cause the Fund to underperform its primary benchmark and/or other similarly situated growth funds. This underperformance may be a result of the portfolio manager’s inability to reallocate Fund assets to respond to rising equity market conditions as quickly as another fund that invests primarily in equity securities. In addition, to maintain compliance with the risk parameters, the Fund may need to liquidate a position, or forego an investment that could have otherwise contributed to Fund performance. Under certain circumstances, the Capital Protection Agreement may require that all of the Fund’s assets be fully allocated to the Protection Component, thus limiting the upside potential for Fund returns during this period. The use of the risk allocation methodology may also impact the Fund’s performance in the event that it does not work as intended, potentially subjecting the Fund to additional expenses as a result of increased trading or allocating a larger portion of the Fund’s assets than necessary to either the Equity Component or Protection Component. Because the Fund may reallocate its assets between and within the Equity Component and the Protection Component as frequently as daily, the Fund’s reallocation may cause it to experience an increase in its portfolio turnover rate resulting in higher costs, which may have a negative effect on the Fund’s performance, particularly during periods of relative instability in equity markets. The Fund’s payment of the capital protection fee to the Capital Protection Provider may also result in the Fund underperforming its primary benchmark and/or other similarly situated growth funds that do not pay a protection fee. Capital Protection Termination Risk. There is a risk that the Protection could terminate. The terms and conditions of the Capital Protection Agreement are designed to protect against certain market risks inherent in any equity investment. It does not protect against certain actions or omissions that constitute gross negligence, fraud, bad faith, willful misconduct, or a criminal act on the part of the Fund, Janus Capital or certain key employees of Janus Capital, or the Fund’s custodian, that negatively impacts a share class’ NAV. Such events will result in the termination of the Protection without any obligation by the Capital Protection Provider, and therefore by the Parent Guarantor, to make any payment to the Fund. The Fund will liquidate in these events, and shareholders will receive the then-current NAV of their share class, which could be below the Protected NAV. Neither the Fund nor Janus Capital is obligated to make any payment to the Fund or cover any shortfall. Therefore, in the event that the Protection is terminated as a result of such events, you could lose money as a result of the Fund losing the Protection under the Capital Protection Agreement, including amounts that would have otherwise been protected. This means that you could receive less than 80% of your investment. Early Termination Events Risk. While the Capital Protection Agreement has an initial 10-year term that may be extended, there is a risk that the Capital Protection Agreement could terminate earlier under various scenarios at the option of the Capital Protection Provider, which are considered Early Termination Events. In such events, the Capital Protection Provider will be obligated to make the payment of the Settlement Amount, if due, to the Fund and the Fund will liquidate. Shareholders receive the higher of their Protected NAV or the then-current NAV for their share class, which will include any Settlement Amount due to the Fund. Examples of “Early Termination Events” include, but not are not limited to (1) if the Fund, Janus Capital, or the Fund’s custodian, fails to comply with certain terms and conditions of the Capital Protection Agreement, including the failure to reallocate Fund assets when such assets fall outside the specified risk parameters, or (2) if the aggregate value of the Fund’s shares outstanding results in the Protection exceeding the Maximum Settlement Amount. The Fund is also expected to liquidate and the Capital Protection Agreement will terminate if, pursuant to the terms of the Capital Protection Agreement, the Protection is triggered. In addition, to the extent that the introduction of laws or a change of law, in each case, not known as of the date of the Capital Protection Agreement results in a new or increased cost of capital or collateral for the Capital Protection Provider or its parent company, the Fund’s Board of Trustees will make a determination whether to approve the Fund paying such increased costs to the Capital Protection Provider or to terminate the Capital Protection Agreement. Only shareholders who hold their shares on the Termination Date are covered by the Protection. Shareholders who redeem prior to the Termination Date receive the then-current NAV which will be higher than the Protected NAV for their share class and will not include any payment of the Protection. Maximum Settlement Amount Risk. The Capital Protection Agreement currently covers the outstanding shares of each class of shares offered by the Fund having an aggregate protected amount up to an initial value of $1.5 billion. If the Maximum Settlement Amount exceeds $1.5 billion without any additional coverage being extended to the Fund, the Capital Protection Provider will not be liable for any Settlement Amount payment in excess of $1.5 billion. None of the Fund, Janus Capital, or any affiliate thereof, will be responsible for any portion of the Settlement Amount, including any amounts which may exceed the Maximum Settlement Amount. Therefore, although the Protection applies, you could lose money to the extent the Aggregate Shortfall Amount exceeds the Maximum Settlement Amount including amounts that would have otherwise been protected. This means that you could receive less than 80% of your investment. In any event, as the Fund’s assets grow, the Fund intends to take such actions as may be deemed necessary, including limiting purchases, to limit the Aggregate Shortfall Amount to a level so that it does not exceed the Maximum Settlement Amount, but there is no guarantee that such efforts will be successful. There is no guarantee that the Capital Protection Provider will agree to extend coverage beyond $1.5 billion. Liquidation Risk. Although the risk allocation methodology is designed so that the NAV of each share class does not fall below its Protected NAV, there is the possibility that the risk allocation methodology may not work as designed or redemptions, particularly a large redemption, may impact the allocation process, and the NAV of any share class falls below its Protected NAV. If this happens, it is expected that the Fund will liquidate as soon as possible following the event and receive payment of the Settlement Amount from the Capital Protection Provider. The NAV of one share class falling below its Protected NAV will result in the Protection being triggered and, as a result, the liquidation of the entire Fund, even though the NAV of one or more other share classes remains at or above its Protected NAV. Other events described in this Prospectus may, at the discretion of the Fund or Capital Protection Provider, as applicable, also terminate the Capital Protection Agreement resulting in payment of the Settlement Amount and liquidation of the Fund. In the event the Protection is triggered and the Fund begins the liquidation process, no other purchases will be permitted, and the payment of redemption proceeds will be suspended, likely from the day the Protection is triggered; shareholders will receive the higher of the then-current NAV per share or the Protected NAV per share for their share class, which will include any Settlement Amount due to the Fund. Redemptions are taxable events. This Prospectus serves as advance notice to shareholders of any rejection of purchases, suspension of the payment of redemption proceeds, and liquidation of the Fund. In the event that the Capital Protection Agreement is terminated and the Fund begins the liquidation process, Janus Capital will make such information available at janus.com/allfunds, or janus.com/advisor/mutual-funds for share classes other than Class D Shares. Notice of the Fund liquidation will otherwise be made when you receive your redemption proceeds. For illustrative purposes to understand a scenario where the Protection is triggered and the Fund proceeds to liquidation, see below: Protected NAV across all share classes is $10.00 –
Opportunity Cost Risk. It is possible that under the terms of the Capital Protection Agreement, the Fund’s allocation to the Equity Component could drop to a low level or be eliminated altogether, especially during periods of heightened volatility in equity markets. This would reduce the Fund’s ability to participate in upward equity market movements, and therefore, represents loss of opportunity compared to a fund that is fully invested in equity securities. Counterparty Risk (Capital Protection Provider and its Parent Company). A shareholder’s ability to receive the Protected NAV from the Fund is dependent on the Fund’s ability to collect the Settlement Amount from the Capital Protection Provider pursuant to the terms of the Capital Protection Agreement or from the Capital Protection Provider’s parent under a separate parent guaranty. Fund transactions involving a counterparty, such as the Capital Protection Provider, are subject to the risk that the counterparty or a third party will not fulfill its obligation to the Fund (“counterparty risk”). Counterparty risk may arise because of the counterparty’s financial condition (i.e., financial difficulties, bankruptcy, or insolvency), market activities and developments, or other reasons, whether foreseen or not. As such, the Fund’s ability to benefit from the Protection may depend on the Capital Protection Provider’s, as well as its parent company’s, financial condition. As an added measure of protection, BNP Paribas, the parent company of the Capital Protection Provider, has issued an absolute, irrevocable and continuing guaranty pursuant to which it guarantees any and all financial obligations of the Capital Protection Provider under the Capital Protection Agreement. There is, however, a risk that the Capital Protection Provider’s parent company may not fulfill its obligations under the guaranty it has issued. Market Risk. The value of the Fund’s portfolio may decrease if the value of an individual company or multiple companies in the portfolio decreases or if the portfolio manager’s belief about a company’s intrinsic worth is incorrect. Further, regardless of how well individual companies perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions. The Fund’s use of the risk allocation methodology is intended to protect against significant downward movement of the NAV per share for a share class, particularly in times of heightened volatility in the equity markets, but the methodology may not protect the Fund if equity markets take a sudden and/or significant fall. Growth Securities Risk. Securities of companies perceived to be “growth” companies may be more volatile than other stocks and may involve special risks. The price of a “growth” security may be impacted if the company does not realize its anticipated potential or if there is a shift in the market to favor other types of securities. Derivatives Risk. Derivatives can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Gains or losses from a derivative can be substantially greater than the derivative’s original cost, and can therefore involve leverage. Derivatives can be complex instruments and may involve analysis that differs from that required for other investment types used by the Fund. If the value of a derivative does not correlate well with the particular market or other asset class to which the derivative is intended to provide exposure, the derivative may not produce the anticipated result. Derivatives can also reduce the opportunity for gain or result in losses by offsetting positive returns in other investments. Derivatives can be less liquid than other types of investments and entail the risk that the counterparty will default on its payment obligations to the Fund. If the counterparty to a derivative transaction defaults, the Fund would risk the loss of the net amount of the payments that it contractually is entitled to receive. To the extent the Fund enters into short derivative positions, the Fund may be exposed to risks similar to those associated with short sales, including the risk that the Fund’s losses are theoretically unlimited. Foreign Exposure Risk. The Fund may have significant exposure to foreign markets, including emerging markets, which can be more volatile than the U.S. markets. As a result, its returns and net asset value may be affected to a large degree by fluctuations in currency exchange rates or political or economic conditions in a particular country. A market swing in one or more countries or regions where the Fund has invested a significant amount of its assets may have a greater effect on the Fund’s performance than it would in a more geographically diversified portfolio. The Fund’s investments in emerging market countries may involve risks greater than, or in addition to, the risks of investing in more developed countries. Emerging Markets Risk. The risks of foreign investing mentioned above are heightened when investing in emerging markets. Emerging markets securities are exposed to a number of additional risks, which may result from less government supervision and regulation of business and industry practices, stock exchanges, brokers, and listed companies, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. To the extent that the Fund invests a significant portion of its assets in the securities of issuers in or companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region which could have a negative impact on the Fund’s performance. Some of the risks of investing directly in foreign and emerging market securities may be reduced when the Fund invests indirectly in foreign securities through various other investment vehicles including derivatives, which also involve specialized risks. Portfolio Turnover Risk. Increased portfolio turnover may result in higher costs, which may have a negative effect on the Fund’s performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders. The risk allocation methodology utilized by the Fund may increase the level of portfolio turnover. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. |
