³  Security Investors, LLC, also known as Guggenheim Investments (the "Investment Manager") has contractually agreed through February 1, 2019 to waive fees and/or reimburse expenses to the extent necessary to limit the ordinary operating expenses (including distribution (12b-1) fees (if any), but exclusive of brokerage costs, dividends on securities sold short, acquired fund fees and expenses, interest, taxes, litigation, indemnification, and extraordinary expenses) (“Operating Expenses”) of the Fund to the annual percentage of average daily net assets for each class of shares as follows: Class A-1.30%, Class C-2.05%, Institutional-1.05%, and Class P-1.30%. The Investment Manager is entitled to reimbursement by the Fund of fees waived or expenses reimbursed during any of the previous 36 months beginning on the date of the expense limitation agreement, provided that the Operating Expenses do not exceed the then-applicable expense cap. The agreement will expire when it reaches its termination or when the Investment Manager ceases to serve as such and it can be terminated by the Fund’s Board of Trustees, with certain waived fees and reimbursed expenses subject to the recoupment rights of the Investment Manager.

EXAMPLE

This 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 then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although the actual costs may be higher or lower, based on these assumptions your costs would be:

	Class A	Class C		Institutional	Class P
		Redeemed	Not Redeemed
1 Year	$603	$310	$210	$109	$134
3 Years	$964	$762	$762	$440	$873
5 Years	$1,349	$1,341	$134	$795	$1,634
10 Years	$2,425	$2,913	$2,913	$1,795	$3,638

The above Example reflects applicable contractual fee waiver/expense reimbursement arrangements for the current duration of the arrangements only.

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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 48% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

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 a diversified portfolio of equity securities, which include common stocks, rights, options, warrants, convertible debt securities, and American Depositary Receipts (“ADRs”), that, when purchased, have market capitalizations that are usually within the range of companies in the Russell 2000 Value Index. Although a universal definition of small-capitalization companies does not exist, the Fund generally defines small-capitalization companies as those whose market capitalization is similar to the market capitalization of companies in the Russell 2000 Value Index, which is an unmanaged index measuring the performance of the small cap value segment of the U.S. equity universe and which includes companies with lower price-to-book ratios and lower forecasted growth values. As of December 31, 2017, the Russell 2000 Value Index consisted of securities of companies with market capitalizations that ranged from $3.94 million to $8.9 billion.

In choosing securities, Security Investors, LLC, also known as Guggenheim Investments (the “Investment Manager”), primarily invests in value-oriented companies. Value-oriented companies are companies that appear to be undervalued relative to assets, earnings, growth potential or cash flows. The Investment Manager uses a blend of quantitative and fundamental analysis to identify securities that appear favorably priced and have the potential to appreciate in value. The Investment Manager regularly evaluates the metrics and data underlying the quantitative model and, from time to time, may make adjustments for a variety of reasons, including, without limitation, to account for changing market, financial or economic conditions.

The Fund may invest a portion of its assets in derivatives, including options and futures contracts. These instruments are used to hedge the Fund’s portfolio, to maintain exposure to the equity markets or to increase returns.

The Fund may invest in a variety of investment vehicles, including those that seek to track the composition and performance of a specific index, such as exchange-traded funds (“ETFs”) and other mutual funds. The Fund may use these investments as a way of managing its cash position or to gain exposure to the equity markets or a particular sector of the equity markets. These investments may be more liquid than investing directly in individual issuers. Certain investment vehicles’ securities and other securities in which the Fund may invest are restricted securities (consisting of securities originally issued in reliance on Rule 144A and Regulation S securities), which may be illiquid.

The Fund may actively trade its investments without regard to the length of time they have been owned by the Fund, which may result in higher portfolio turnover.

The Fund typically sells a security when its issuer is no longer considered a value company, shows deteriorating fundamentals or falls short of the Investment Manager’s expectations, among other reasons.

The Fund may invest in a limited number of industries or industry sectors, including the technology and financial sectors.

Under adverse, unstable or abnormal market conditions, 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.

SUMMARY PROSPECTUS | 3

PRINCIPAL RISKS

The value of an investment in the Fund will fluctuate and is subject to investment risks, which means investors could lose money. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any governmental agency. There is no assurance that the Fund will achieve its investment objective. The principal risks of investing in the Fund are summarized below.

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.

Counterparty Credit Risk—The Fund makes investments in financial instruments and over-the-counter-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, or to hedge a position. Through these investments, the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments to meet its contractual obligations. If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment 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 held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease.

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.

Derivatives Risk—Derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation and legal restrictions. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. 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.

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 in value more than 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.

Foreign Securities and Currency Risk—Foreign securities carry unique or additional risks when compared to U.S. securities, including currency fluctuations, adverse political and economic developments, unreliable or untimely information, less liquidity and more volatility, limited legal recourse and higher transactional costs.

Investment in Investment Vehicles Risk—Investing in other investment vehicles, including exchange-traded funds ("ETFs"), closed-end 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 are subject to, among other risks, the risk that the ETF's 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 ETF's shares.

Leverage Risk—The Fund’s use of leverage, through borrowings or instruments such as derivatives, may cause the Fund to be more volatile and riskier than if it had not been leveraged.

Liquidity and Valuation Risk—It may be difficult for the Fund to purchase and sell particular investments 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

4 | SUMMARY PROSPECTUS

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 may be heightened for fixed-income instruments because of the near historically low interest rate environment as of the date of this prospectus.

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, causing the Fund to 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, which are ultimately passed on to shareholders of the Fund. Active and frequent trading may also result in adverse tax consequences.

Market Risk—The value of, or income generated by, the securities held by the Fund may fluctuate rapidly and unpredictably as a result of factors affecting individual companies or changing economic, political, social or financial market conditions throughout the world. The performance of these investments may underperform the general securities markets or other types of securities.

Quantitative Model Risk—There is no guarantee that a quantitative model or algorithm used by the Investment Manager, and the investments selected based on the model or algorithm, will produce the desired results. The Fund may be adversely affected by imperfections, errors or limitations in the construction and implementation of the model or algorithm and the Investment Manager’s ability to properly analyze or timely adjust the metrics or update the data underlying the model or features of the algorithm.

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.

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.

Small-Capitalization Securities Risk—The Fund is subject to the risk that small-capitalization securities may underperform other segments of the equity market or the equity market as a whole. Securities of small-capitalization companies may be more speculative, volatile and less liquid than securities of larger companies. Small-capitalization companies tend to have inexperienced management as well as limited product and market diversification and financial resources, and may be more vulnerable to adverse developments than mid- or large- capitalization companies.

Sector Emphasis Risk-Financial Sector Risk—The financial sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and the impact of more stringent capital requirements. The Fund may be adversely affected by events or developments negatively impacting the financial sector or issuers within the financial sector, including banks.

Sector Emphasis Risk-Technology Stocks Risk—Stocks of companies involved in the technology sector, including information technology companies, may be very volatile. The Fund may be adversely affected by events or developments negatively impacting the technology sector or issuers within the technology sector.

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.

MANAGEMENT OF THE FUND

Security Investors, LLC, also known as Guggenheim Investments, serves as the investment manager of the Fund. James P. Schier, Scott Hammond, Farhan Sharaff, Gregg Strohkorb and David G. Toussaint are primarily responsible for the day-to-day management of the Fund. They hold the titles of Senior Managing Director and Portfolio Manager; Managing Director and Portfolio Manager; Assistant Chief Investment Officer, Equities, Senior Managing Director and Portfolio Manager; Director and Portfolio Manager; and Director and Portfolio Manager, respectively, with the Investment Manager. Mr. Schier has managed the Fund since its inception (July 2008). Messrs. Hammond, Sharaff, and Strohkorb have co-managed the Fund since 2015. Mr. Toussaint has co-managed the Fund since 2017.

PURCHASE AND SALE OF FUND SHARES

You may purchase or redeem Fund shares through your broker/dealer, other financial intermediary that has an agreement with Guggenheim Funds Distributors, LLC, the Fund’s distributor, or, for shares of each class other than Class P shares, through the Fund’s transfer agent. You may purchase, redeem or exchange shares of any class of the Fund on any day the New York Stock Exchange is open for business. The minimum initial investment for Class A and Class C shares is $2,500. The minimum subsequent investment is $100. Class A and Class C do not have a minimum account balance.

The Institutional Class minimum initial investment is $2 million, although the Investment Manager may waive this requirement at its discretion. The Institutional Class has a minimum account balance of $1 million. Due to the relatively high cost of maintaining accounts below the minimum account balance, the Fund reserves the right to redeem shares if an account balance falls below the minimum account balance for any reason. Investors will be given 60 days' notice to reestablish the minimum account balance. If the account balance is not increased, the account may be closed and the proceeds sent to the investor. Institutional Class shares of the Fund will be redeemed at net asset value on the day the account is closed.

Class P shares of the Fund are offered through broker/dealers and other financial intermediaries with which Guggenheim Funds Distributors, LLC has an agreement for the use of Class P shares of the Fund in investment products, programs or accounts. Class P shares do not have a minimum initial investment amount, subsequent investment amount or a minimum account balance. The Fund reserves the right to modify its minimum investment amount and account balance requirements at any time, with or without prior notice to you.

TAX INFORMATION

Fund distributions are taxable as ordinary income or capital gains (or a combination of both), unless your investment is through an IRA or other tax-advantaged retirement account. Investments through tax-advantaged accounts may sometimes become taxable upon withdrawal.

PAYMENTS TO BROKER/DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase Fund shares through a broker/dealer or other financial intermediary, the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker/dealer or other intermediary and your sales person to recommend the Fund over another investment. Ask your sales person or visit your financial intermediary’s website for more information.
