INVESTMENT OBJECTIVE

The Guggenheim Large Cap Value Fund (the “Fund”) seeks long-term growth of capital.

¹  Security Investors, LLC, also known as Guggenheim Investments (the “Investment Manager”), has contractually agreed through February 1, 2016 to waive fees and/or reimburse expenses to the extent necessary to limit the ordinary operating expenses (including distribution (12b-1) fees, 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-1.15%, Class B-1.90%, Class C-1.90% and Institutional Class-0.90%. The Fund may have “Total Annual Fund Operating Expenses After Fee Waiver” greater than the expense cap as a result of any acquired fund fees and expenses or other expenses that are excluded from the calculation. The Investment Manager has also agreed through February 1, 2016, to waive the amount of the Fund’s management fee to the extent necessary to offset the proportionate share of any management fee paid by the Fund with respect to any Fund investment in an underlying fund for which the Investment Manager or any of its affiliates also serves as investment manager. 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 the Operating Expenses do not exceed the then-applicable expense cap. Each 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:

The above Example reflects applicable contractual fee waiver/expense reimbursement arrangements for the 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 40% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund pursues its objective by investing, under normal market conditions, at least 80% of its assets (net assets, plus the amount of any borrowing for investment purposes) in equity securities, which include common stocks, rights, options, warrants, convertible debt securities of both U.S. and U.S. dollar-denominated foreign issuers, and American Depositary Receipts (“ADRs”), of companies that, when purchased, have market capitalizations that are usually within the range of companies in the Russell 1000 Value Index. Although a universal definition of large market capitalization companies does not exist, the Fund generally defines large market capitalization companies as those whose market capitalization is similar to the market capitalization of companies in the Russell 1000 Value Index, which is an unmanaged index measuring the performance of the large cap value segment of the U.S. equity universe and which includes companies with lower price-to-book ratios and lower expected growth values.

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 analysis and fundamental research to identify securities that appear favorably priced and that may be able to sustain or improve their pre-tax ROIC (Return on Invested Capital) over time. The Fund may, consistent with its status as a non-diversified mutual fund, focus its investments in a limited number of issuers.

The Fund may invest a portion of its assets in futures contracts, options on futures contracts, and options on securities. 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, while maintaining liquidity.

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, from time to time, invest a portion of its assets in technology stocks.

Under adverse or unstable market conditions, the Fund could invest some or all of its assets in cash, fixed-income securities, government bonds, money market securities, or repurchase agreements. The Fund may be unable to pursue or achieve its investment objective during that time and temporary defensive investments could reduce the benefit from any upswing in the market.

PRINCIPAL RISKS

The value of an investment in the Fund will fluctuate and is subject to investment risks, which means investors could lose money. The principal risks of investing in the Fund are summarized below.

Depositary Receipt Risk—The Fund may hold the securities of non-U.S. companies in the form of ADRs and GDRs. The underlying securities of the ADRs and Global Depositary Receipts ("GDRs") 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 ADRs and GDRs 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.

SUMMARY PROSPECTUS | 3

Derivatives Risk—Derivatives may pose risks in addition to and greater than those associated with investing directly in securities 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. Some of the derivatives in which the Fund invests are traded (and privately negotiated) in the over-the-counter ("OTC") market. OTC derivatives are subject to heightened credit, liquidity and valuation risks.

Equity Securities Risk—Equity securities include common stocks and other equity securities (and securities convertible into stocks), and the prices of equity securities fluctuate in value more than other investments. They reflect changes in the issuing company’s financial condition and changes in the overall market. Common stocks generally represent the riskiest investment in a company. The Fund may lose a substantial part, or even all, of its investment in a company’s stock. Growth stocks may be more volatile than value stocks.

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

Investment in Investment Vehicles Risk—Investing in other investment vehicles, including 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.

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.

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—In certain circumstances, 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 believes should be the price of the investment.

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 trading that can accompany active management, also called “high turnover,” may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund.

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 because of the interconnected global economies and financial markets.

Non-Diversification Risk—The Fund is considered non-diversified because it invests a large portion of its assets in a small number of issuers. As a result, the Fund is more susceptible to risks associated with those issuers than a more diversified portfolio, and its performance may be more volatile.

Regulatory and Legal Risk—U.S. and other regulators and governmental agencies may implement additional regulations and legislators may 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). These may impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Technology Stocks Risk—Stocks of companies involved in the technology sector may be very volatile.

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.

SUMMARY PROSPECTUS | 5

MANAGEMENT OF THE FUND

Security Investors, LLC, also known as Guggenheim Investments (the “Investment Manager”), serves as the investment manager of the Fund. Mark Mitchell is primarily responsible for the day-to-day management of the Fund and holds the title of Portfolio Manager with the Investment Manager. He has managed the Fund since July 2005.

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 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. Class B shares are closed to new subscriptions from either new or existing shareholders. 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 advance 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. Fund shares will be redeemed at net asset value on the day the account is closed.

TAX INFORMATION

Fund distributions are taxable as ordinary income or capital gains (or a combination of both), unless your investment is in 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.
