Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 56% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:10.02pt;font-weight:bold;">PRINCIPAL INVESTMENT STRATEGIES</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund seeks to exceed the total return of the S&P 500® Index (the “Index”). The Fund pursues its objective by investing, under normal circumstances, at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in: (i) equity securities issued by companies that have market capitalizations within the range of companies in the Index; (ii) investment vehicles that provide exposure to companies that have market capitalizations within the range of companies in the Index; and (iii) equity derivatives that, when purchased, provide exposure to (i.e., economic characteristics similar to) equity securities of companies with market capitalizations usually within the range of companies in the Index and equity derivatives based on large-capitalization indices, including large-capitalization growth indices and large-capitalization value indices deemed appropriate by Security Investors, LLC, also known as Guggenheim Investments (the “Investment Manager”). The Fund will usually also invest in fixed-income instruments and cash investments to collateralize derivatives positions and to increase investment return. As of December 31, 2023, the Index consisted of securities of companies with market capitalizations that ranged from approximately $6.5 billion to $3 trillion.Equity securities in which the Fund may invest include common stocks, rights and warrants, and American Depositary Receipts (“ADRs”). Derivatives in which the Fund may invest include options, futures contracts, swap agreements (including, but not limited to, total return swap agreements), and forward contracts (some of these instruments may be traded in the over-the-counter market). Fixed-income securities and other securities in which the Fund may invest include debt securities selected from a variety of sectors and credit qualities (principally, investment grade), principally, corporate bonds, participations in and assignments of syndicated bank loans, asset-backed securities (including mortgage-backed securities, collateralized debt obligations (“CDOs”), collateralized loan obligations (“CLOs”) and other structured finance investments), U.S. government and agency securities (including those not backed by the full faith and credit of the U.S. government), mezzanine and preferred securities, commercial paper, zero-coupon bonds, non-registered or restricted securities (consisting of securities originally issued in reliance on Rule 144A and Regulation S), step-up securities (such as step-up bonds) and convertible securities that the Investment Manager believes offer attractive yield and/or capital appreciation potential. The Fund may invest in securities listed, traded or dealt in other countries. The Fund may hold securities of any duration or maturity. Fixed-income securities in which the Fund may invest may pay fixed or variable rates of interest. The Fund may invest in a variety of investment vehicles, principally closed-end funds, exchange-traded funds (“ETFs”) and other mutual funds.Allocation decisions within the actively managed equity, passive equity and actively managed fixed-income sleeves are at the discretion of the Investment Manager and are based on the Investment Manager’s judgment of the current investment environment (including market volatility), the attractiveness of each asset category, the correlations among Index components, individual positions or each asset category, and expected returns. In selecting investments for the Fund, the Investment Manager uses quantitative analysis, credit research and due diligence on issuers, regions and sectors to select the Fund’s investments and other proprietary strategies to identify securities and other assets that, in combination, are expected to contribute to exceeding the total return of the Index.Derivative instruments may be used extensively by the Investment Manager to maintain exposure to the equity and fixed-income markets, to hedge the Fund’s portfolio, or to increase returns. The Investment Manager may determine to sell a security for several reasons including the following: (1) to meet redemption requests; (2) to close-out or unwind derivatives transactions; (3) to realize gains; or (4) if market conditions change.The Fund invests a substantial portion of its assets in investment companies advised by the Investment Manager, or an affiliate of the Investment Manager, that invest in short-term fixed-income or floating rate securities (“Guggenheim short-term funds”). These funds are designed primarily to provide an alternative to investing directly and separately in various short-term fixed-income or floating rate securities. The Fund invests in these investment companies for various portfolio management purposes, including for cash management and liquidity management purposes and to seek to obtain exposure with a higher level of return on investments used to collateralize derivatives positions and achieve greater diversification and trading efficiency than would usually be experienced by investing directly and separately in fixed-income or floating rate securities. Investments by the Fund in these investment companies significantly increase the Fund’s exposure to the following asset categories: (i) a broad range of high yield, high risk debt securities rated below the top four long-term rating categories by a nationally recognized statistical rating organization (also known as “junk bonds”) or, if unrated, determined by the Investment Manager, to be of comparable quality; (ii) CLOs, other asset-backed securities and similarly structured debt investments; and (iii) other short-term fixed or floating rate debt securities. Such investments expose the Fund to the risks of these asset categories and decreases in the value of these investments may cause the Fund to deviate from its investment objective.Under adverse or unstable market conditions or abnormal circumstances, the Fund could invest some or all of its assets in cash, derivatives, fixed-income instruments, government bonds, money market instruments, repurchase agreements or securities of other investment companies. The Fund may be unable to pursue or achieve its investment objective during that time and temporary investments could reduce the benefit from any upswing in the market.

A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Asset Backed Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Asset-Backed Securities Risk—Investors in asset-backed securities, including residential mortgage-backed securities, commercial mortgage-backed securities and other structured finance investments (such as collateralized mortgage obligations), generally receive payments that are part interest and part return of principal. These payments may vary based on the rate at which the underlying borrowers pay off their loans. As a result, asset-backed securities are particularly subject to credit risk and borrower defaults on the obligations underlying the asset-backed security will result in losses. In addition, asset-backed securities are typically particularly sensitive to changes in interest rates, which can cause the prices of asset-backed securities to be increasingly volatile and adversely affect the Fund’s holdings of asset-backed securities. Some asset-backed securities, including mortgage-backed securities, may have structures that make their performance based on changes in interest rates and other factors difficult to predict, causing their prices to be volatile. Asset-backed securities are also particularly subject to market, liquidity and valuation, prepayment and extension risks, and are also subject to risk of impairment of the value of the underlying asset. Additional risks relating to investments in asset-backed securities may arise principally because of the type of asset-backed securities in which the Fund invests, with such risks primarily associated with the particular assets collateralizing the asset-backed securities, the structure of such asset-backed securities or the tranche or priority of the asset-backed security held by the Fund.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Collateralized Loan Obligations and Collateralized Debt Obligations Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Collateralized Loan Obligations and Collateralized Debt Obligations Risk—CLOs bear many of the same risks as other forms of asset-backed securities, including interest rate risk, credit risk and default risk. As they are backed primarily by commercial loans, CLOs also bear many of the same risks as investing in loans directly. However, in addition to the risks associated with investing in commercial loans, the complex structure and highly leveraged nature of a CLO poses additional risks. CLOs incur indebtedness by issuing classes or “tranches” that vary in risk and yield. CLOs may experience substantial losses attributable to loan defaults or trading losses. Such losses on the underlying assets are borne first by the holders of subordinate tranches, which may take the form of an equity interest. The Fund’s investments in CLOs may decrease in market value when the CLO’s assets experience loan defaults or credit impairment, losses that exceed the most subordinate tranches, or market anticipation of loan defaults and investor aversion to CLO securities as a class.CDOs are structured similarly to CLOs and bear many of the same risks as CLOs including interest rate risk, credit risk and default risk. CDOs are subject to additional risks because they are backed by pools of assets other than commercial loans, including securities (such as other asset-backed securities), synthetic instruments or bonds, and may be highly leveraged. Like CLOs, losses incurred by a CDO are borne first by holders of the most subordinate tranches. Accordingly, the risks of CDOs depend largely on the type of underlying collateral and the tranche of CDOs in which the Fund invests. Moreover, CDOs that obtain their exposure through synthetic investments are exposed to risks associated with derivative instruments.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Commercial Paper Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Commercial Paper Risk—The value of the Fund’s investment in commercial paper, which is an unsecured promissory note that generally has a maturity date between one and 270 days and is issued by a U.S. or foreign entity, is susceptible to changes in the issuer’s financial condition or credit quality. Investments in commercial paper are usually discounted from their value at maturity. Commercial paper can be fixed-rate or variable rate and can be adversely affected by changes in interest rates.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Convertible Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Convertible Securities Risk—Convertible securities may be subordinate to other securities. The total return for a convertible security depends, in part, upon the performance of the underlying security into which it can be converted. The value of convertible securities tends to decline as interest rates increase. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Counterparty Credit Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Counterparty Credit Risk—The Fund makes investments in financial instruments and OTC-traded derivatives involving counterparties to gain exposure to a particular group of securities, index, asset class or other reference asset without actually purchasing those securities or investments, to hedge a position, or for other investment purposes. Through these investments and related arrangements (e.g., prime brokerage or securities lending arrangements or derivatives transactions), the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments or otherwise to meet its contractual obligations. If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease. Counterparty credit risk also includes the related risk of having concentrated exposure to such a counterparty.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Credit Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income or other debt instrument or a counterparty to a derivatives transaction or other transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time, defaults or otherwise fails to meet its obligations. Actual or perceived changes in economic, social, public health, financial or political conditions in general or that affect a particular type of instrument, issuer, guarantor or counterparty can reduce the ability of the party to meet its obligations, which can affect the credit quality, liquidity and/or value of an instrument. The value of an instrument also may decline for reasons that relate directly to the issuer, guarantor or counterparty, such as management performance, financial leverage and reduced demand for goods and services or an actual or perceived change in financial condition or reputation. The issuer, guarantor or counterparty could also suffer a rapid decline in credit rating, which would adversely affect the value, price volatility and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Depositary Receipt Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Depositary Receipt Risk—The Fund may hold the securities of non-U.S. companies in the form of depositary receipts. The underlying securities of the depositary receipts in the Fund’s portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Fund’s portfolio. In addition, the value of the securities underlying the depositary receipts may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Derivatives Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Derivatives Risk—Derivatives and other similar instruments (collectively referred to in this paragraph as “derivatives”) pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, market conditions and market risk, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, illiquidity, valuation, operational and legal restrictions and risk. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in leverage, which may cause the Fund to be more volatile and riskier than if it had not been leveraged. Changes in the value of a derivative may also create sudden margin delivery or settlement payment obligations for the Fund, which can materially affect the performance of the Fund and its liquidity and other risk profiles. If the Investment Manager is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. In addition, the Fund’s use of derivatives may cause the Fund to realize higher amounts of short term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened counterparty credit, legal, liquidity and valuation risks. Certain risks also are specific to the derivatives in which the Fund invests.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Futures Contracts Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Futures Contracts Risk—Futures contracts are exchange-traded contracts that call for the future delivery of an asset at a certain price and date, or cash settlement of the terms of the contract. Risks of futures contracts may be caused by an imperfect correlation between movements in the price of the instruments and the price of the underlying assets. In addition, there is a risk that the Fund may not be able to enter into a closing transaction because of an illiquid market. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Investment Manager, thus limiting the ability to implement the Fund’s strategies. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s net asset value (“NAV”). Futures are also subject to leverage and liquidity risks.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Options Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Options Risk—Options and options on futures contracts give the holder of the option the right, but not the obligation, to buy (or to sell) a position in a security or in a contract to the writer of the option, at a certain price. Options are subject to correlation risk because there may be an imperfect correlation between the options and the markets for underlying instruments that could cause a given transaction to fail to achieve its objectives. The successful use of options depends on the Investment Manager’s ability to predict correctly future price fluctuations and the degree of correlation between the markets for options and the underlying instruments. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Investment Manager, thus limiting the ability to implement the Fund’s strategies. Options are also particularly subject to leverage risk and can be subject to liquidity risk.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Swap Agreements Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Swap Agreements Risk—Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the underlying index). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, for certain standardized swaps, must be exchange-traded through a futures commission merchant and/or cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. While exchange trading and central clearing are intended to reduce counterparty credit risk and increase liquidity, they do not make swap transactions risk-free. Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Equity Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Equity Securities Risk—Equity securities include common stocks and other equity and equity-related securities (and securities convertible into stocks). The prices of equity securities generally fluctuate more than those of fixed-income investments, may rise or fall rapidly or unpredictably, and may reflect real or perceived changes in the issuing company’s financial condition and changes in the overall market or economy. A decline in the value of equity securities held by the Fund will adversely affect the value of your investment in the Fund. Common stocks generally represent the riskiest investment in a company and dividend payments (if declared) to preferred stockholders generally rank junior to payments due to a company’s debtholders. The Fund may lose a substantial part, or even all, of its investment in a company’s stock.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Extension Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Extension Risk—Certain debt instruments, including mortgage- and other asset-backed securities, are subject to the risk that payments on principal may occur at a slower rate or later than expected. In this event, the expected maturity could lengthen and the Fund’s investment may sharply decrease in value and the Fund’s income from the investment may quickly decline. These types of instruments are particularly subject to extension risk, and offer less potential for gains, during periods of rising interest rates. In addition, the Fund may be delayed in its ability to reinvest income or proceeds from these instruments in potentially higher yielding investments, which would adversely affect the Fund.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Foreign Securities and Currency Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Foreign Securities and Currency Risk—Foreign securities carry unique or additional risks when compared to U.S. securities, including currency fluctuations, adverse political (including geopolitical) and economic developments, unreliable or untimely information, less liquidity and more volatility, limited legal recourse and higher transactional costs.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Growth Stocks Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Growth Stocks Risk—Growth stocks typically invest a high portion of their earnings back into their business and may lack the dividend yield that could cushion their decline in a market downturn. Growth stocks may be more volatile than other stocks because they are more sensitive to investor perceptions regarding the growth potential of the issuing company.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | High Yield and Unrated Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	High Yield and Unrated Securities Risk—High yield, below investment grade and unrated high risk debt securities (which also may be known as “junk bonds”) are regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. These securities generally present additional risks compared to investment grade bonds and are typically less liquid, and therefore more difficult to value accurately and sell at an advantageous price or time, and present more credit and default risk than investment grade bonds. The price of high yield securities tends to be subject to greater volatility due to issuer-specific factors, such as operating results and outlook and to real or perceived adverse economic and competitive industry conditions. This exposure may be obtained through investments in other investment companies. Based on its investment strategies, a significant portion of the Fund’s investments (directly or indirectly) can be comprised of high yield, below investment grade and unrated securities and thus particularly prone to the foregoing risks, which may result in losses to the Fund.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Interest Rate Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Interest Rate Risk—Fixed-income and other debt instruments are subject to the possibility that interest rates could change. Changes in interest rates may adversely affect the Fund’s investments in these instruments, such as the value or liquidity of, and income generated by, the investments. Interest rates may change as a result of a variety of factors, and the change may be sudden and significant, with unpredictable impacts on the financial markets and the Fund’s investments. Fixed-income and other debt instruments with longer durations are more sensitive to changes in interest rates and, thus, subject to more volatility than similar instruments with shorter durations. Generally, when interest rates increase, the values of fixed-income and other debt instruments decline, sometimes suddenly and significantly. When interest rates decrease, the values of fixed-income and other debt instruments generally rise. During periods of rising interest rates, because changes in interest rates on adjustable rate securities may lag behind changes in market rates, the value of such securities may decline until their interest rates reset to market rates. During periods of declining interest rates, because the interest rates on adjustable rate securities generally reset downward, their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities. The Fund’s yield, returns and performance may be adversely affected by changing interest rates. Changes in monetary policy may exacerbate the risks associated with changing interest rates.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Investment in Investment Vehicles Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Investment in Investment Vehicles Risk—Investing in other investment vehicles, including ETFs, closed-end funds, Guggenheim short-term funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles’ expenses, which will reduce the Fund’s performance. In addition, investments in an ETF or a listed closed-end fund are subject to, among other risks, the risk that the shares may trade at a discount or premium relative to the net asset value of the shares and the listing exchange may halt trading of the shares.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Investment in Loans Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Investment in Loans Risk—The Fund may invest in loans directly or indirectly through assignments or participations. Investments in loans, including loan syndicates and other direct lending opportunities, involve special types of risks, including credit risk, interest rate risk, counterparty risk, prepayment risk, risk of subordination to other creditors, extension risk and risk of insufficient or lack of protection under the federal securities law. Loans may offer a fixed or floating interest rate. Loans are often below investment grade and may be unrated. The Fund’s investments in loans can also be difficult to value accurately because of, among other factors, limited public information regarding the loan or the borrowers and may be more susceptible to liquidity risk than fixed-income instruments of similar credit quality and/or maturity. The Fund is also subject to the risk that the value of any collateral for the loan may be insufficient or unavailable to cover the borrower’s obligations should the borrower fail to make payments, become insolvent, or otherwise default. This risk is increased if the Fund’s loans are secured by a single asset. The Fund may also invest in loans that are not secured by collateral which typically present greater risks than collateralized loans. Transactions in loans are often subject to long settlement periods and often require consent from borrowers and/or an agent acting for the lenders, thus potentially limiting the ability of the Fund to invest sale proceeds in other investments and to use proceeds to meet its current redemption obligations. The Fund (or an underlying fund) thus is subject to the risk of selling other investments at disadvantageous times or prices or taking other actions necessary to raise cash to meet its redemption obligations. Participations in loans may subject the Fund to the credit risk of both the borrower and the seller of the participation and may make enforcement of loan covenants, if any, more difficult for the Fund as legal action may have to go through the seller of the participation (or an agent acting on its behalf). Covenants contained in loan documentation are intended to protect lenders and investors by imposing certain restrictions and other limitations on a borrower’s and the credit group’s operations or assets and by providing certain information and consent rights to lenders. In addition to operational covenants, loans and other debt obligations often contain financial covenants, which require a borrower and the related credit group to satisfy certain financial tests at periodic intervals or to maintain compliance with certain financial metrics. The Fund is exposed to, including through investment in underlying funds, loans and other similar debt obligations that are sometimes referred to as “covenant-lite” loans or obligations, which generally are loans or other similar debt obligations that lack financial maintenance covenants or possess fewer or contingent financial maintenance covenants and other financial protections for lenders and investors. These “covenant-lite” loans or similar debt obligations are particularly subject to the risks associated with investments in loans as described above.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Large Capitalization Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Large-Capitalization Securities Risk—The Fund is subject to the risk that large-capitalization securities may underperform other segments of the equity market or the equity market as a whole. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and may not be able to attain the high growth rate of smaller companies, especially during extended periods of economic expansion.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Leverage Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Leverage Risk—The Fund’s use of leverage, through borrowings or instruments such as derivatives and reverse repurchase agreements, may cause the Fund to be more volatile and riskier and magnify the Fund's losses to an extent greater than if it had not been leveraged.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Liquidity and Valuation Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Liquidity and Valuation Risk—It may be difficult for the Fund to purchase and sell particular investments to meet redemption requests or otherwise within a reasonable time at a fair price, or the price at which it has been valued by the Investment Manager for purposes of the Fund’s net asset value, causing the Fund to be less liquid and unable to realize what the Investment Manager believes should be the price of the investment. Valuation of portfolio investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks are heightened in a changing interest rate or volatile environment.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Management Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Management Risk—The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns. As a result of these and other factors, the Fund may lose value or fail to meet its investment objective or underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active and frequent trading that can accompany active management, also called “high turnover,” may have a negative impact on performance. Active and frequent trading may result in higher brokerage costs or mark-up charges and tax costs, which are ultimately passed on to shareholders of the Fund. Active and frequent trading may also result in adverse tax consequences.In addition, the Fund is subject to the risks associated with the Investment Manager's allocation of assets between or among sleeves, including the timing and amount of such allocations.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Risk—The value of, or income generated by, the investments held by the Fund may fluctuate rapidly and unpredictably. These fluctuations may be frequent and significant. In addition, the Fund may incur losses as a result of various market and economic factors, such as those affecting individual companies or issuers or particular industries, or from broader influences, such as general market conditions. In addition, developments related to economic, political (including geopolitical), social, public health, market, extreme weather, natural or man-made disasters or other conditions or events may cause volatility in financial markets and reduced liquidity in equity, credit and/or debt markets, which could adversely impact the Fund and its investments and their value and performance. Under such conditions, the Fund may experience significant redemption activity by shareholders and could be forced to sell portfolio securities or other assets at unfavorable prices in an effort to generate sufficient cash to pay redeeming shareholders. The Fund's investments may perform poorly or underperform the general securities markets or other types of securities.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Preferred Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Preferred Securities Risk—A company’s preferred stock generally pays dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the company’s financial condition or prospects.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Prepayment Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Prepayment Risk—Certain debt instruments, including loans and mortgage- and other asset-backed securities, are subject to the risk that payments on principal may occur more quickly or earlier than expected. If this occurs, the Fund might be forced to forego future interest income on the principal repaid early and to reinvest income or proceeds at generally lower interest rates, thus reducing the Fund’s yield. These types of instruments are particularly subject to prepayment risk, and offer less potential for gains, during periods of declining interest rates.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Regulatory and Legal Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Regulatory and Legal Risk—U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund (such as regulations related to investments in derivatives and other transactions). These regulations and laws impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Restricted Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | U.S. Government Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	U.S. Government Securities Risk—U.S. government securities may or may not be backed by the full faith and credit of the U.S. government. U.S. government securities are subject to the risks associated with fixed-income and debt securities, particularly interest rate risk and credit risk. In addition, U.S. government securities not backed by the full faith and credit of the U.S. government involve credit risk that is greater than other types of U.S. government securities.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Value Stocks Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Value Stocks Risk—Value stocks are subject to the risk that the intrinsic value of the stock may never be realized by the market or that the price goes down.
A C Inst P Shares | Guggenheim StylePlus-Large Core Fund | Zero Coupon and Payment In Kind Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Zero Coupon and Payment-In-Kind Securities Risk—Zero coupon and payment-in-kind securities pay no cash interest income and usually are sold at substantial discounts from their value at maturity. Zero coupon and payment-in-kind securities are subject to greater market value fluctuations from changing interest rates than debt obligations of comparable maturities that make current cash-pay interest payments.
