* The Funds are very different from most mutual funds in that they seek to provide leveraged or leveraged inverse investment results on a daily basis. The Inverse Funds pursue investment goals which are inverse to the performance of their respective benchmark, a result opposite of most other mutual funds. The pursuit of such investment goals has the following implications: — The Funds are riskier than alternatives that do not use leverage because the performance of an investment in a Leveraged or Leveraged Inverse Fund is magnified. The effect of leverage on a fund will generally cause the Fund’s performance to not match the performance of the Fund’s benchmark over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will very likely differ from the return of the Fund’s benchmark stated in the Fund’s investment objective for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., 2x) and the cumulative performance of the Fund’s benchmark. The risk of a Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, the Fund’s performance for periods greater than one day is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Fund’s investment objective, before accounting for fees and fund expenses. — The Funds are not suitable for all investors and are designed to be utilized only by sophisticated investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting, and (d) intend to actively monitor and manage their investments. Investors who do not understand the Funds or do not intend to actively manage their funds and monitor their investments should not buy shares of the Funds. — There is no assurance that any Fund will achieve its objectives and an investment in a Fund could lose money. No single Fund is a complete investment program.

The U.S. Securities and Exchange Commission has not approved or disapproved these securities or passed upon the accuracy or adequacy of this Prospectus. Any representation to the contrary is a criminal offense.

The Nova Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified.

The effect of leverage on the Fund will generally cause the Fund’s performance to not match the performance of the Fund’s benchmark (as described below) over a period of time greater than a single trading day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will very likely differ from 1.5x of the return of the Fund’s underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below).

The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is 150% of the performance of the S&P 500^® Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

This table describes the fees and expenses that you may pay if you buy and hold Advisor Class Shares or Investor Class Shares of the Fund.

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 your actual costs may be higher or lower, based on these assumptions your costs would be:

performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 116% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and leveraged derivative instruments, which primarily consist of equity index swap agreements, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the Fund’s benchmark. The Fund’s use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The S&P 500^® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poor’s Corporation (“S&P”) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $1.3 billion to $546 billion as of June 30, 2012. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

As with all mutual funds, a shareholder is subject to the risk that his or her investment could lose money. In addition to this risk, the Fund is subject to a number of additional risks that may affect the value of its shares, including:

Active Trading Risk – Active trading, also called “high portfolio turnover,” may result in higher brokerage costs or mark-up charges, which may negatively affect Fund performance and result in short-term capital gains, which have a negative tax effect. Large movements of assets into and out of the Fund due to active trading also may adversely affect the Fund’s ability to achieve its investment objective.

Compounding affects all investments, but has a more significant impact on a leveraged index fund. In general, particularly during periods of higher index volatility, compounding will cause longer-term results to be more or less than the return of the Fund’s benchmark. This effect becomes more pronounced as volatility increases.

Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) underlying index performance; (b) underlying index volatility; (c) financing rates associated with leverage; (d) other Fund expenses; (e) dividends paid by companies in the underlying index; and (f) period of time. The chart below illustrates the impact of two principal factors – volatility and index performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no dividends paid by the companies included in the underlying index; (b) no Fund expenses; and (c) a cost of leverage of zero percent. If Fund expenses were included, the Fund’s performance would be lower than shown.

Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 150% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 150% of the performance of the underlying index.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2012 is 19.12%. The underlying index’s highest one-year volatility rate during the five year period is 30.42%. The underlying index’s annualized performance for the five year period ended June 30, 2012 is -0.60%.

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.

Counterparty Credit Risk – The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments, including swap agreements, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Fund’s investment.

Derivatives Risk – The Fund’s investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Fund’s investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested.

Early Closing Risk – The Fund is subject to the risk that unanticipated early closings of securities exchanges and other financial markets may result in the Fund’s inability to buy or sell securities or other financial instruments on that day and may cause the Fund to incur substantial trading losses.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Leveraging Risk – The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Fund’s investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Fund’s investment strategy involves consistently applied leverage, the value of the Fund’s shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error.

such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.

Market Risk – The Fund’s investments in securities and derivatives, in general, are subject to market risks that may cause their prices, and therefore the Fund’s value, to fluctuate over time. An investment in the Fund may lose money.

Non-Diversification Risk – The Fund is considered non-diversified and can invest a greater portion of its assets in securities of individual issuers than a diversified fund. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.

OTC Trading Risk – Certain of the derivatives in which the Fund may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.

Passive Investment Risk – The Fund is not actively managed and the Advisor does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that is actively managed.

Repurchase Agreement Risk – The Fund’s investment in repurchase agreements may be subject to market and credit risk with respect to the collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.

Tracking Error Risk – The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Fund’s performance to be less than you expect.

Trading Halt Risk – If a trading halt occurs, the Fund may temporarily be unable to purchase or sell securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Fund’s ability to use leverage and may prevent the Fund from achieving its investment objective.

The following bar chart shows the performance of the Investor Class Shares of the Fund from year to year. The variability of performance over time provides an indication of the risks of investing in the Fund. The following table shows the average annual total returns of the Investor Class Shares and Advisor Class Shares of the Fund over different periods of time in comparison to the performance of a broad-based market index. The figures in the bar chart and table assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.rydex-sgi.com or by calling Guggenheim Investments Client Services at 800.820.0888.

The performance information shown below for Investor Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 13.66%.

The after-tax returns presented in the table below are calculated using highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold shares of the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

Advisor Class Shares and Investor Class Shares held through a third party (e.g., a brokerage account) are subject to the following minimum initial investment amounts:

Advisor Class Shares held directly at Guggenheim Investments generally do not require a minimum investment amount. For Investor Class Shares, non-managed accounts (including retirement accounts) held directly at Guggenheim Investments generally require a minimum account balance of $25,000. Accounts managed by financial professionals are not subject to minimum account balance requirements. However, accounts opened through a financial intermediary (non-direct) will be subject to your financial intermediary’s minimum initial investment amount and account balance requirements, which may be different than the amounts above.

There are no minimum amounts for subsequent investments in the Fund except for subsequent investments made via Automated Clearing House (“ACH”). Guggenheim Investments reserves the right to modify its minimum account balance requirements at any time, with or without prior notice to you.

The Fund redeems its shares continuously and investors may sell their shares back to the Fund on any day that the New York Stock Exchange (the “NYSE”) is open for business (a “Business Day”). You will ordinarily submit your transaction order through your financial intermediary or other securities dealers through which you opened your shareholder account or through Guggenheim Investments if you opened your account directly with the Fund. The Fund also offers you the option to send redemption orders to Guggenheim Investments by mail, fax or telephone.

Fund distributions are generally 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.

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), 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.

The S&P 500^® Fund (the “Fund”) seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is the S&P 500^® Index (the “underlying index”).

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 196% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its objective without investing directly in the securities included in the underlying index, or in the same proportion that those securities are represented in the underlying index. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P 500^® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poor’s Corporation (“S&P”) on a statistical basis, and which generally represent large-capitalization companies with capitalizations ranging from $1.3 billion to $546 billion as of June 30, 2012. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Tracking Error Risk – The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Fund’s performance to be less than you expect.

Updated performance information is available on the Fund’s website at www.rydex-sgi.com or by calling Guggenheim Investments Client Services at 800.820.0888.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 8.79%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

Accounts managed by financial professionals are not subject to minimum account balance requirements. Accounts opened through a financial intermediary (non-direct) will be subject to your financial intermediary’s minimum initial investment amount and account balance requirements, which may be different than the amounts above.

H-Class accounts held directly at Guggenheim Investments (other than those that are managed by financial professionals) are subject to a minimum account balance of $25,000 for non-managed accounts (including retirement accounts).

Fund distributions are generally 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.

The Inverse S&P 500^® Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that match the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.

Because the Fund seeks daily inverse investment results, the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will very likely differ from the inverse return of the Fund’s underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., -1x) and the cumulative performance of the underlying index.

The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the consequences of seeking daily inverse investment results, (b) understand the risk of shorting and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is the inverse (opposite) of the performance of the S&P 500^® Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio. However, the Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Unlike a traditional index fund, the Fund’s investment objective is to perform exactly opposite the underlying index, and the Fund generally will not own the securities included in the underlying index. Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Fund’s investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The S&P 500^® Index is a capitalization-weighted index composed of 500 common stocks, which are chosen by the Standard & Poor’s Corporation (“S&P”) on a statistical basis, and which generally represent large-capitalization companies with a capitalizations ranging from $1.3 billion to $546 billion as of June 30, 2012. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry.

Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the underlying index. This effect becomes more pronounced as volatility increases.

Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the underlying index.

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may outperform other segments of the equity market or the equity market as a whole.

Liquidity 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. While the Fund only intends to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a “limit move,” it may be difficult or impossible for the Fund to liquidate such investments. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.

Passive Investment Risk – The Fund is not actively managed and the Advisor does not attempt to take defensive positions in rising markets. Therefore, the Fund may be subject to greater losses in a rising market than a fund that is actively managed.

Short Sales Risk – Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Fund’s ability to engage in short selling.

Tracking Error Risk – The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Fund’s performance to be less than you expect.

The NASDAQ-100^® Fund (the “Fund”) seeks to provide investment results that correspond, before fees and expenses, to a benchmark for over-the-counter securities on a daily basis. The Fund’s current benchmark is the NASDAQ-100 Index^® (the “underlying index”).

This table describes the fees and expenses that you may pay if you buy and hold Advisor Class Shares or Investor Class Shares of the Fund.

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 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 Total 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 94% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Depositary Receipt Risk – The Fund may hold the securities of non-U.S. companies in the form of ADRs. The underlying securities of the ADRs 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 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.

Foreign Issuer Exposure Risk – The Fund may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.

Industry and Technology Sector Concentration Risk – The risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Fund’s investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology companies also may fluctuate widely in response to such events.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Tracking Error Risk – The Advisor may not be able to cause the Fund’s performance to correspond to that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Fund’s performance to be less than you expect.

The Inverse NASDAQ-100^® Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that match the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.

The Fund seeks to provide investment results that match, before fees and expenses, the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is the inverse (opposite) of the performance of the NASDAQ-100 Index^® (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

This table describes the fees and expenses that you may pay if you buy and hold Advisor Class Shares or Investor Class Shares of the Fund.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

Unlike a traditional index fund, the Fund’s investment objective is to perform exactly opposite the underlying index, and the Fund generally will not own the securities included in the underlying index. Instead, the Fund employs as its investment strategy a program of engaging in short sales of securities included in the underlying index and investing to a significant extent in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Fund’s investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse exposure to the underlying index. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also may invest in American Depositary Receipts (“ADRs”) to gain inverse exposure to international companies included in the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to the securities of companies included in the underlying index. The NASDAQ-100 Index^® is a modified capitalization-weighted index composed of 100 of the largest non-financial companies listed on The Nasdaq Stock Market with capitalizations ranging from $24 billion to $542.7 billion as of June 30, 2012. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. Currently, the NASDAQ-100 Index^® is concentrated in technology companies. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2012 is 22.52%.

Fund distributions are generally 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.

The Mid-Cap 1.5x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified.

The effect of leverage on the Fund will generally cause the Fund’s performance to not correlate to the performance of the Fund’s benchmark (as described below) over a period of time greater than a single trading day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will very likely differ from 1.5x of the return of the Fund’s underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., 1.5x) and the cumulative performance of the underlying index (as defined below).

The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark for mid-cap securities on a daily basis. The Fund’s current benchmark is 150% of the performance of the S&P MidCap 400^® Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 141% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Advisor will attempt to consistently apply leverage to increase the Fund’s exposure to 150% of the underlying index. As a result, the Fund’s use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies included in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P MidCap 400^® Index is a modified capitalization-weighted index composed of 400 mid cap stocks chosen by S&P for market size, liquidity, and industry group representation. The S&P MidCap 400^® Index covers approximately 7% of the U.S. equities market and generally represents mid-capitalization companies with capitalizations ranging from $113 million to $11.8 billion as of June 30, 2012. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks.

The S&P 500^® Pure Growth Fund (the “Fund”) seeks to provide investment results that match, before fees and expenses, the performance of a benchmark for large-cap growth securities on a daily basis. The Fund’s current benchmark is the S&P 500 Pure Growth Index (the “underlying index”).

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 586% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The S&P 500 Pure Growth Index is narrow in focus, containing only those S&P 500^® companies with strong growth characteristics. As of June 30, 2012, the S&P 500 Pure Growth Index included companies with capitalizations ranging from $1.3 billion to $546 billion. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold short-term U.S. government securities or cash equivalents to collateralize its derivative positions. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

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.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Tracking Error Risk – The Advisor may not be able to cause the Fund’s performance to match that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and those of the underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Fund’s performance to be less than you expect.

The Fund also may purchase American Depositary Receipts (“ADRs”) to gain exposure to foreign Banking Companies and U.S. government securities. Under U.S. Securities and Exchange Commission regulations, the Fund may not invest more than 5% of its total assets in the equity securities of any company that derives more than 15% of its revenues from brokerage or investment management activities.

Banking Sector Risk – To the extent that the Fund’s investments are exposed to issuers conducting business in the banking sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Banking Companies also may fluctuate widely in response to such events.

Mid-Capitalization Securities Risk – The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Small-Capitalization Securities Risk – The Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Temporary Defensive Investment Risk – The Fund does not attempt to take defensive positions in declining markets. Therefore, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions in declining markets.

If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Precious Metals Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund will invest to a significant extent in the securities of Precious Metals Companies that have small to mid-sized capitalizations. Precious metals include gold, silver, platinum and other precious metals. Precious Metals Companies include precious metal manufacturers; distributors of precious metal products, such as jewelry, metal foil or bullion; mining and geological exploration companies; and companies that provide services to Precious Metals Companies. The Fund also may purchase American Depositary Receipts (“ADRs”) to gain exposure to foreign Precious Metals Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the precious metals sector and, therefore, may be concentrated in an industry or group of industries within the precious metals sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Mid-Capitalization Securities Risk – The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Precious Metals Sector Risk – To the extent that the Fund’s investments are exposed to issuers conducting business in the precious metals sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Precious Metals Companies also may fluctuate widely in response to such events.

Small-Capitalization Securities Risk – The Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

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 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 Total 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 822% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Advisor Class Shares and Investor Class Shares held through a third party (e.g., a brokerage account) are subject to the following minimum initial investment amounts:

Fund distributions are generally 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.

The Europe 1.25x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks leveraged investment results. As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified.

The effect of leverage on the Fund will generally cause the Fund’s performance to not correlate to the performance of the Fund’s benchmark (as described below) over a period of time greater than a single trading day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will very likely differ from 1.25x of the return of the Fund’s underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., 1.25x) and the cumulative performance of the underlying index (as defined below).

The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking leveraged investment results, and (c) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.

The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark. The Fund’s current benchmark is 125% of the fair value of the STOXX 50^® Index (the “underlying index”).

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 318% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Advisor will attempt to consistently apply leverage to increase the Fund’s exposure to 125% of the underlying index. As a result, the Fund’s use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also may invest in American Depositary Receipts (“ADRs”) to gain exposure to the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The STOXX 50^® Index is a capitalization-weighted index composed of 50 European blue chip stocks consisting of capitalizations ranging from $25.6 billion to $192.7 billion as of June 30, 2012. Index members are chosen by Stoxx Ltd. from 16 countries under criteria designed to identify highly liquid companies that are leaders in their sectors. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Correlation and Compounding Risk – A number of factors may affect the Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Fund’s performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Fund’s investment objective, before accounting for fees and Fund expenses.

Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 125% of the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 125% of the performance of the underlying index.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2012 is 24.93%. The underlying index’s highest one-year volatility rate during the five year period is 39.84%. The underlying index’s annualized performance for the five year period ended June 30, 2012 is -9.16%.

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.

Currency Risk – Indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political developments in the U.S. or abroad. In particular, the Fund may have indirect and direct exposure to the euro. The price of euro has fluctuated widely over the past several years, and volatility has increased in recent months, due, in part, to concern over the sovereign debt levels of certain European Union (EU) members and the potential effect of this debt on the EU members’ participation in the European Monetary Union and the value of the euro. These and other factors may adversely affect the long-term value of the euro in terms of purchasing power in the future. A decline in the price of the euro may adversely affect the Fund’s performance.

Geographic Concentration in Europe Risk – Because a significant portion of the Fund’s investments are concentrated in issuers located in Europe, the Fund is susceptible to loss due to adverse market, political, regulatory, and geographic events affecting the various countries and regions in Europe. The European economy is diverse and includes both large, competitive economies and small, struggling economies. The European economy is vulnerable to decreasing imports or exports, changes in governmental regulations on trade, changes in the exchange rate of the euro and recessions in EU economies.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Leveraging Risk –The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Fund’s investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Fund’s investment strategy involves consistently applied leverage, the value of the Fund’s shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error.

Status as a Regulated Investment Company Risk – The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future.

The effect of leverage on the Fund will generally cause the Fund’s performance to not correlate to the performance of the Fund’s benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will very likely differ from twice the return of the Fund’s underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below).

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 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 Total 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 0% of the average value of its portfolio. However, the Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund employs as its investment strategy a program of investing in the common stock of companies that are generally within the capitalization range of the underlying index and derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Fund’s use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also may invest in American Depositary Receipts (“ADRs”) to gain exposure to the underlying index. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The Nikkei 225 Stock Average is a price-weighted average of 225 top-rated Japanese companies listed on the First Section of the Tokyo Stock Exchange that are selected to be both highly liquid and representative of Japan’s industrial structure. As of June 30, 2012, the Nikkei 225 Stock Average included companies with small, medium and large capitalizations ranging from $311 million to $137.9 billion. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Correlation and Compounding Risk – A number of factors may affect the Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding and the times at which the Fund and the underlying index calculate their respective NAVs, the Fund’s performance is likely to be either greater than or less than the performance of the underlying index times the stated multiple in the Fund’s investment objective, before accounting for fees and Fund expenses.

Areas shaded lighter represent those scenarios where the Fund can be expected to return more than twice the performance of the underlying index; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than twice the performance of the underlying index.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2012 is 20.02%. The underlying index’s highest one-year volatility rate during the five year period is 35.11%. The underlying index’s annualized performance for the five year period ended June 30, 2012 is -5.17%.

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.

Currency Risk – The Fund’s indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. The Fund also may incur transaction costs in connection with conversions between various currencies.

Geographic Concentration in Japan Risk – Targeting Japan could hurt the Fund’s performance if Japan’s economy performs poorly as a result of political and economic conditions that affect the Japanese market. Japanese stocks tend to be more volatile than their U.S. counterparts, for reasons ranging from political and economic uncertainties, to a higher risk that essential information may be incomplete or erroneous. The Fund may be more volatile than a geographically diversified equity fund.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Mid-Capitalization Securities Risk – The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Small-Capitalization Securities Risk – The Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

The following bar chart shows the performance of the H-Class Shares of the Fund from year to year. The variability of performance over time provides an indication of the risks of investing in the Fund. The following table shows the average annual total returns of the H-Class Shares of the Fund over different periods of time in comparison to the performance of a broad-based market index. Effective May 1, 2009, the Fund changed comparative benchmarks from the Topix 100 Index to the Nikkei 225 Stock Average. This change occurred as a result of the Fund’s change in name and investment strategy. Prior to May 1, 2009, the Fund’s investment strategy sought to provide 125% exposure to the Topix 100 Index; therefore, the performance and average annual total returns shown below for periods prior to May 1, 2009 may have differed had the Fund’s current investment strategy, which seeks to provide 200% exposure to the Nikkei 225 Stock Average, been in effect during those periods. The Nikkei 225 Stock Average more appropriately reflects the Fund’s investment universe. The figures in the bar chart and table assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.rydex-sgi.com or by calling Guggenheim Investments Client Services at 800.820.0888.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 6.83%.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

Fund distributions are generally 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.

The Emerging Markets 2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified.

The effect of leverage on the Fund will generally cause the Fund’s performance to not correlate to the performance of the Fund’s benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will very likely differ from twice the return of the Fund’s underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., 2x) and the cumulative performance of the underlying index (as defined below).

The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is 200% of the performance of the BNY Mellon Emerging Markets 50 ADR Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 883% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund invests principally in securities of companies included in the underlying index and in derivative instruments which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in the underlying index or to securities whose performance is highly correlated to that of the underlying index. The Fund’s use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also may invest in exchange-traded funds (“ETFs”) that provide exposure to emerging market countries and in American Depositary Receipts (“ADRs”) to gain exposure to the underlying index. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in securities of companies in the underlying index and derivatives and other instruments whose performance is expected to correspond to that of the underlying index. The BNY Mellon Emerging Markets 50 ADR Index is a capitalization weighted index comprised of the 50 largest emerging market based ADRs having a free-float market capitalization ranging from approximately $4.6 billion to over $65.9 billion as of June 30, 2012. To the extent the Fund’s underlying index is concentrated in a particular industry the Fund will necessarily be concentrated in that industry. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

The underlying index’s annualized historical volatility rate for the five year period ended June 30, 2012 is 29.32%. The underlying index’s highest one-year volatility rate during the five year period is 44.95%. The underlying index’s annualized performance for the five year period ended June 30, 2012 is -1.36%.

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.

Emerging Markets Risk – The Fund’s investments may have exposure to emerging markets. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile because they are countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor.

Investment in Investment Companies Risk – Investing in other investment companies subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies’ expenses.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Leveraging Risk –The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Fund’s investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Fund’s investment strategy involves consistently applied leverage, the value of the Fund’s shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error.

Mid-Capitalization Securities Risk – The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Portfolio Turnover Risk – The Fund’s strategy may frequently involve buying and selling portfolio securities to rebalance the Fund’s exposure to various market sectors. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

The following bar chart shows the performance of the H-Class Shares of the Fund for the last calendar year. The variability of performance over time provides an indication of the risks of investing in the Fund. The following table shows the average annual total returns of the H-Class Shares of the Fund over different periods of time in comparison to the performance of a broad-based market index.

The Inverse Emerging Markets 2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide daily leveraged investment results that correlate to the opposite of the performance of a specific benchmark on a daily basis, as result opposite of most mutual funds. As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified.

The effect of leverage on the Fund will generally cause the Fund’s performance to not correlate to the performance of the Fund’s benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will very likely differ from twice the inverse return of the Fund’s underlying index (as defined below) for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., -2x) and the cumulative performance of the underlying index (as defined below).

The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.

The Fund seeks to provide investment results that correlate, before fees and expenses, to the performance of a specific benchmark on a daily basis. The Fund’s current benchmark is 200% of the inverse (opposite) of the performance of the BNY Mellon Emerging Markets 50 ADR Index (the “underlying index”). The Fund does not seek to achieve its investment objective over a period of time greater than one day.

The Fund employs as its investment strategy a program of engaging in short sales of securities generally included in the underlying index and investing in leveraged derivatives instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. The Fund’s investment in derivatives serves as a substitute for directly selling short each of the securities included in the underlying index and produces inverse leveraged exposure to the underlying index.

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.

Derivatives Risk – The Fund’s investments in derivatives may pose risks in addition to those associated with investing directly insecurities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, lack of availability and counterparty risk. When used to generate leveraged exposure, the Fund’s investments in derivatives may expose the Fund to potentially dramatic losses (or gains) in the value of the derivative instruments. The Fund could lose more than the principal amount invested.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may outperform other segments of the equity market or the equity market as a whole.

Mid-Capitalization Securities Risk – The Fund is subject to the risk that medium-capitalization stocks may outperform other segments of the equity market or the equity market as a whole.

The Fund employs as its investment strategy a program of investing in derivative instruments, which primarily consist of equity index swaps, futures contracts, and options on securities, securities indices, and futures contracts. Investing in derivative instruments enables the Fund to pursue its investment objective without investing directly in the securities included in the underlying index or in the same proportion that those securities are represented in the underlying index.

Correlation and Compounding Risk – A number of factors may affect the Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the underlying index has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Fund’s performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the underlying index times the stated multiple in the Fund’s investment objective, before accounting for fees and Fund expenses.

Historical underlying index volatility and performance are not indications of what the underlying index volatility and performance will be in the future.

Leveraging Risk –The Fund achieves leveraged exposure to the underlying index through the use of derivative instruments.

As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Fund’s investment strategy involves consistently applied leverage, the value of the Fund’s shares will tend to increase or decrease more than the value of any increase or decrease in the underlying index. Leverage also will have the effect of magnifying tracking error.

Status as A Regulated Investment Company Risk – The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization, but such regulations may be issued in the future.

Fund distributions are generally 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.

The Real Estate Fund (the “Fund”) seeks to provide capital appreciation by investing in companies that are involved in the real estate industry, including real estate investment trusts (“REITs”) (collectively, “Real Estate Companies”).

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 974% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Under normal circumstances, the Fund invests substantially all (at least 80%) of its net assets in equity securities of Real Estate Companies that are traded in the United States and in derivatives, which primarily consist of futures contracts and options on securities, futures contracts, and stock indices. The Fund will invest to a significant extent in the securities of Real Estate Companies that have small to mid-sized capitalizations. Real Estate Companies, which also include master limited partnerships, are primarily engaged in the ownership, construction, management, financing or sale of residential, commercial or industrial real estate. Real Estate Companies also may include companies whose products and services are related to the real estate industry, such as building supply manufacturers, mortgage lenders, or mortgage servicing companies. The Fund also may purchase American Depositary Receipts (“ADRs”) to gain exposure to foreign Real Estate Companies and U.S. government securities. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund invests in the securities of a limited number of issuers conducting business in the real estate sector and, therefore, may be concentrated in an industry or group of industries within the real estate sector. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Industry and Real Estate Sector Risk – The risk of concentrating Fund investments in a limited number of issuers conducting business in the same industry or group of industries is that the Fund will be more susceptible to the risks associated with that industry or group of industries than a fund that does not concentrate its investments. To the extent that the Fund’s investments are exposed to issuers conducting business in the real estate sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Real Estate Companies also may fluctuate widely in response to such events.

Mid-Capitalization Securities Risk – The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Small-Capitalization Securities Risk – The Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 14.71%.

Fund distributions are generally 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.

The Government Long Bond 1.2x Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks daily leveraged investment results. As a result, the Fund may be riskier than alternatives that do not use leverage because the performance of an investment in the Fund is magnified.

The effect of leverage on the Fund will generally cause the Fund’s performance to not correspond to the performance of the Fund’s benchmark (as described below) over a period of time greater than one day. This means that the return of the Fund for a period of longer than a single trading day will be the result of each day’s compounded returns over the period, which will likely differ from the return of the Fund’s benchmark for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s cumulative return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., 1.2x) and the cumulative performance of the benchmark (as defined below).

The Fund seeks to provide investment results that correspond, before fees and expenses, to a benchmark for U.S. government securities on a daily basis. The Fund’s current benchmark is 120% of the daily price movement of the Long Treasury Bond. The Long Treasury Bond is the U.S. Treasury bond with the longest maturity, which is currently 30 years. The price movement of the Long Treasury Bond is based on the daily price change of the most recently issued Long Treasury Bond. The Fund does not seek to achieve its investment objective over a period of time greater than one day.

This table describes the fees and expenses that you may pay if you buy and hold Advisor Class Shares or Investor Class Shares of the Fund.

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 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 Total 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 2,322% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund employs as its investment strategy a program of investing in U.S. government securities and derivative instruments, which primarily consist of futures contracts, interest rate swaps, and options on securities and futures contracts. Futures and options contracts, and interest rate swaps, if used properly, may enable the Fund to meet its objective by increasing the Fund’s exposure to the securities included in its benchmark or to securities whose performance is highly correlated to its benchmark. The Fund’s use of derivatives and the leveraged investment exposure created by such use is expected to be significant. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in fixed income securities issued by the U.S. government (and derivatives thereof). Some of the Fund’s U.S. government securities, or cash equivalents, will be used to collateralize its derivative positions. The Fund also may invest in zero coupon U.S. Treasury bonds and enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Compounding affects all investments, but has a more significant impact on a leveraged benchmark fund. In general, particularly during periods of higher benchmark volatility, compounding will cause longer-term results to be more or less than the return of the Fund’s benchmark. This effect becomes more pronounced as volatility increases.

Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) the performance of the Long Treasury Bond; (b) volatility of the Long Treasury Bond; (c) financing rates associated with leverage; (d) other Fund expenses; and (e) period of time. The chart below illustrates the impact of two principal factors – volatility and index performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no Fund expenses; and (b) a cost of leverage of zero percent. If Fund expenses were included, the Fund’s performance would be lower than shown.

Areas shaded lighter represent those scenarios where the Fund can be expected to return more than 120% of the performance of the Long Treasury Bond; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return less than 120% of the performance of the Long Treasury Bond.

The Long Treasury Bond’s annualized historical volatility rate for the five year period ended June 30, 2012 is 18.82%. The Long Treasury Bond’s highest one-year volatility rate during the five year period is 25.13%. The Long Treasury Bond’s annualized performance for the five year period ended June 30, 2012 is 12.70%.

The historical volatility and performance of the Long Treasury Bond are not indications of what the Long Treasury Bond volatility and performance will be in the future.

Fixed Income Risk – The Fund’s investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuer’s creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may cause the value of the Fund to decrease. In addition, the Fund’s investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes.

Leveraging Risk –The Fund achieves leveraged exposure to the Long Treasury Bond through the use of derivative instruments. The more the Fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. The Fund’s investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. Since the Fund’s investment strategy involves consistently applied leverage, the value of the Fund’s shares will tend to increase or decrease more than the value of any increase or decrease in the Long Treasury Bond. Leverage also will have the effect of magnifying tracking error.

Tracking Error Risk – The Advisor may not be able to cause the Fund’s performance to correspond to that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and the Long Treasury Bond, rounding of share prices, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Fund’s performance to be less than you expect.

The performance information shown below for Investor Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 6.41%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

Advisor Class Shares and Investor Class Shares held through a third party (e.g., a brokerage account) are subject to the following minimum initial investment amounts:

The Fund redeems its shares continuously and investors may sell their shares back to the Fund on any day that the New York Stock Exchange (the “NYSE”) is open for business (a “Business Day”) excluding bond market holidays. You will ordinarily submit your transaction order through your financial intermediary or other securities dealers through which you opened your shareholder account or through Guggenheim Investments if you opened your account directly with the Fund. The Fund also offers you the option to send redemption orders to Guggenheim Investments by mail, fax or telephone.

Fund distributions are generally 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.

The Inverse Government Long Bond Strategy Fund (the “Fund”) is very different from most other mutual funds in that it seeks to provide investment results that correlate to the opposite of the performance of a specific benchmark on a daily basis, a result opposite of most mutual funds. As a result, the Fund may be riskier than alternatives that do not rely on the use of derivatives to achieve their investment objectives.

Because the Fund seeks daily inverse investment results, the return of the Fund for a period longer than a full trading day will be the result of each day’s compounded returns over the period, which will likely differ from the inverse return of the daily price movement of the benchmark for that period. As a consequence, especially in periods of market volatility, the path or trend of the benchmark during the longer period may be at least as important to the Fund’s return for the longer period as the cumulative return of the benchmark for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., -1x) and the cumulative performance of the benchmark.

The Fund seeks to provide total returns that inversely correlate, before fees and expenses, to the price movements of a benchmark for U.S. Treasury debt instruments or futures contracts on a specified debt instrument on a daily basis. The Fund’s current benchmark is the daily price movement of the Long Treasury Bond. The Long Treasury Bond is the U.S. Treasury bond with the longest maturity, which is currently 30 years. The price movement of the Long Treasury Bond is based on the daily price change of the most recently issued Long Treasury Bond. The Fund does not seek to achieve its investment objective over a period of time greater than one day.

This table describes the fees and expenses that you may pay if you buy and hold Advisor Class Shares or Investor Class Shares of the Fund.

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 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 Total 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 1,107% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

Unlike a traditional index fund, the Fund’s investment objective is to perform, on a daily basis, exactly opposite the daily price movement of the Long Treasury Bond. The Fund employs as its investment strategy a program of engaging in short sales and investing to a significant extent in derivative instruments, which primarily consist of futures contracts, interest rate swaps, and options on securities and futures contracts. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments with economic characteristics that should perform opposite to fixed income securities issued by the U.S. government. On a day-to-day basis, the Fund may hold U.S. government securities or cash equivalents to collateralize its short sales and derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Correlation and Compounding Risk – A number of factors may affect the Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. The risk of the Fund not achieving its daily investment objective will be more acute when the Long Treasury Bond has an extreme one-day movement approaching 50%. In addition, as a result of compounding, because the Fund has a single day investment objective, the Fund’s performance for periods greater than one day is likely to be either greater than or less than the inverse of the performance of the Long Treasury Bond times the stated multiple in the Fund’s investment objective, before accounting for fees and Fund expenses.

Compounding affects all investments, but has a more significant impact on a leveraged fund. In general, particularly during periods of higher index volatility, compounding will cause longer term results to be more or less than the inverse of the return of the benchmark. This effect becomes more pronounced as volatility increases.

Fund performance for periods greater than one day can be estimated given any set of assumptions for the following factors: (a) performance of the Long Treasury Bond; (b) volatility of the Long Treasury Bond; (c) financing rates associated with leverage; (d) other Fund expenses; and (e) period of time. The chart below illustrates the impact of two principal factors – volatility and index performance – on Fund performance. The chart shows estimated Fund returns for a number of combinations of performance and volatility over a one-year period. Performance shown in the chart assumes: (a) no Fund expenses; and (b) a cost of leverage of zero percent. If Fund expenses were included, the Fund’s performance would be lower than shown.

Areas shaded lighter represent those scenarios where the Fund can be expected to return more than the inverse performance of the Long Treasury Bond; conversely, areas shaded darker represent those scenarios where the Fund can be expected to return the same or less than the inverse performance of the Long Treasury Bond.

The historical volatility and performance of the Long Treasury Bond are not indications of what the Long Treasury Bond volatility and performance will be in the future.

Tracking Error Risk – The Advisor may not be able to cause the Fund’s performance to correlate to that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and the Long Treasury Bond, rounding of share prices, regulatory policies, and high portfolio turnover rate all contribute to tracking error. Tracking error may cause the Fund’s performance to be less than you expect.

The performance information shown below for Investor Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is -6.11%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

Advisor Class Shares and Investor Class Shares held through a third party (e.g., a brokerage account) are subject to the following minimum initial investment amounts:

The Fund redeems its shares continuously and investors may sell their shares back to the Fund on any day that the New York Stock Exchange (the “NYSE”) is open for business (a “Business Day”) excluding bond market holidays. You will ordinarily submit your transaction order through your financial intermediary or other securities dealers through which you opened your shareholder account or through Guggenheim Investments if you opened your account directly with the Fund. The Fund also offers you the option to send redemption orders to Guggenheim Investments by mail, fax or telephone.

Fund distributions are generally 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.

The High Yield Strategy Fund (the “Fund”) seeks to provide investment results that correlate, before fees and expenses, to the performance of the high yield bond market.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 583% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund seeks to gain exposure similar to the total return of the high yield bond market as represented by the global universe (excluding emerging market countries) of fixed rate, non-investment grade debt by investing in credit default swaps, high yield securities, futures and other financial instruments with economic characteristics comparable to that of the high yield bond market as represented by U.S. and Canadian high yield bonds. Generally, high yield bonds, which are also commonly referred to as “junk bonds,” are those bonds rated BB+ and lower by Standard & Poor’s Rating Service or Ba1 and lower by Moody’s Investor Services, Inc., but may include unrated bonds that the Advisor determines are of similar quality. The Advisor will consider the liquidity, transaction costs and relative value of available investments in seeking to meet the Fund’s investment objective.

The Fund will primarily invest in credit default swaps to gain exposure similar to the high yield bond market. Credit default swaps are instruments which allow for the full or partial transfer of third party credit risk, with respect to a particular entity or entities, from one counterparty to the other. A buyer of credit default swaps is buying credit protection or mitigating credit risk. A seller of credit default swaps is selling credit protection or assuming credit risk. The Fund will normally be a seller of credit protection (assuming credit risk) as it seeks to gain exposure to the high yield bond market, but also may buy credit protection from time to time in order to maintain the appropriate level of exposure to the high yield bond market, such as during times of heavy redemption activity.

In addition, the Fund may invest in bond futures for the purpose of managing duration risk. For cash management purposes, the Fund may invest in other fixed income securities and money market instruments. The Fund also may invest in other financial instruments including corporate notes, convertible debt securities, preferred securities and derivatives thereof, as well as other investment companies, including exchange-traded funds (“ETFs”), unit investment trusts, and closed-end funds, that invest primarily in high yield debt instruments. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments that in combination have economic characteristics similar to the U.S. and Canadian high yield bond markets and/or in high yield debt securities.

Credit Default Swaps Risk – The Fund’s investments in credit default swaps may subject the Fund to greater risks than if the Fund were to invest directly in high yield bonds. When investing in credit default swaps, the Fund is exposed to the credit risk of both the counterparty to the credit default swap and the issuer of the underlying reference obligation. The Fund could realize a loss on its investment if it does not correctly evaluate the creditworthiness of the issuer of the bond or other reference obligation on which the credit default swap is based, as well as the continued creditworthiness of the counterparty. Investments in credit default swaps also are subject to liquidity risk.

Credit Risk – The Fund could lose money if the issuer or guarantor of a debt instrument in which it invests becomes unwilling or unable to make timely principal and/or interest payments, or to otherwise meet its obligations.

Derivatives Risk – The Fund’s investments in derivatives, such as bond futures, may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, lack of availability and counterparty risk. The Fund could lose more than the principal amount invested.

Foreign Issuer Exposure Risk – The Fund may invest in securities of foreign companies directly or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.

High Yield Risk – The Fund may invest in high yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities.

Investment in Investment Companies Risk – Investing in other investment companies, including ETFs, subjects the Fund to those risks affecting the investment company, including the possibility that the value of the underlying securities held by the investment company could decrease. Moreover, the Fund will incur its pro rata share of the expenses of the underlying investment companies’ expenses.

Issuer Specific Risk – The value of a security may increase or decrease for a number of reasons which directly relate to the issuer. For example, with respect to the Fund, perceived poor management performance, financial leverage or reduced demand of the issuer’s goods or services may contribute to a decrease in the value of a security. A decrease in the value of the securities of an issuer or guarantor of a debt instrument may cause the value of your investment in the Fund to decrease.

Leveraging Risk – The Fund’s investment in derivative instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The cost of investing in such instruments generally increases as interest rates increase, which will lower the Fund’s return.

As a consequence, especially in periods of market volatility, the path or trend of the high yield bond market during the longer period may be at least as important to the Fund’s return for the longer period as the cumulative return of the high yield bond market for the relevant longer period. Further, the return for investors who invest for a period longer than a single trading day will not be the product of the return of the Fund’s stated investment goal (e.g., -1x) and the cumulative performance of the high yield bond market.

The Fund is not suitable for all investors. The Fund should be utilized only by investors who (a) understand the risk of shorting and (b) intend to actively monitor and manage their investments. Investors who do not meet these criteria should not buy shares of the Fund. An investment in the Fund is not a complete investment program.

The Fund seeks to provide investment results that inversely correlate, before fees and expenses, to the performance of the high yield bond market.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 0% of the average value of its portfolio. However, the Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund seeks to gain inverse exposure to the performance of the high yield bond market by investing in credit default swaps, futures and other financial instruments with economic characteristics opposite to that of the high yield bond market as represented

by U.S. and Canadian high yield bonds. Generally, high yield bonds, which are also commonly referred to as “junk bonds,” are those bonds rated BB+ and lower by Standard & Poor’s Rating Service or Ba1 and lower by Moody’s Investor Services, Inc., but may include unrated bonds that the Advisor determines are of similar quality. The Advisor will consider the liquidity, transaction costs and relative value of available investments in seeking to meet the Fund’s objective.

The Fund will primarily invest in credit default swaps to gain inverse exposure to the high yield bond market. Credit default swaps are instruments which allow for the full or partial transfer of third party credit risk, with respect to a particular entity or entities, from one counterparty to the other. A buyer of credit default swaps is buying credit protection or mitigating credit risk. A seller of credit default swaps is selling credit protection or assuming credit risk. The Fund will normally be a buyer of credit protection as it seeks to gain inverse exposure to the high yield bond market, but also may sell credit protection (assuming credit risk) from time to time in order to maintain the appropriate level of exposure to the high yield bond market, such as during times of heavy redemption activity.

In addition, the Fund may invest in bond futures for the purpose of managing duration risk. For cash management purposes, the Fund may invest in other fixed income securities and money market instruments. The Fund also may invest in other financial instruments including corporate notes, convertible debt securities, preferred securities and derivatives thereof, as well as other investment companies, including exchange-traded funds, unit investment trusts, and closed-end funds, that provide inverse exposure to the high yield debt market. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in financial instruments that in combination should provide inverse exposure to the U.S. and Canadian high yield bond markets.

Credit Risk – Changes in an issuer’s financial strength or in an issuer’s or debt security’s credit rating may affect a security’s value and thus have an impact on Fund performance.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

The Fund redeems its shares continuously and investors may sell their shares back to the Fund on any day that the New York Stock Exchange (the “NYSE”) is open for business (a “Business Day”) excluding bond market holidays. You will ordinarily submit your transaction order through your financial intermediary or other securities dealers through which you opened your shareholder account or through Guggenheim Investments if you opened your account directly with the Fund. The Fund also offers you the option to send redemption orders to Guggenheim Investments by mail, fax or telephone.

Fund distributions are generally 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.

The U.S. Long Short Momentum Fund (the “Fund”) seeks long-term capital appreciation.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 190% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund seeks to respond to the dynamically changing economy by moving its investments among different sectors or industries. Each day the Advisor, using a quantitative methodology, ranks approximately seventy different industries based on several measures of momentum including price momentum. The Fund then buys long the common stock of companies in the top ranked industries and may hedge broad market risk or sell short the common stock of companies in the lowest ranked industries. The Fund invests in equity securities, including small, mid, and large-capitalization securities, such as U.S. traded common stocks and American Depositary Receipts (“ADRs”), but also may invest in derivative instruments, particularly when seeking “short” exposure, which primarily consist of equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Equity index swaps and futures and options contracts enable the Fund to pursue its investment objective without investing directly in the securities of companies included in the different sectors or industries to which the Fund is seeking exposure. The Fund may invest in derivatives to hedge or gain leveraged exposure to a particular sector, industry or company depending on market conditions. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also may enter into short sales of broad-based stock indices for hedging purposes in an effort to reduce portfolio risk or volatility. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. On a day-to-day basis, the Fund may hold U.S. government securities, short-term, high quality (rated AA or higher) fixed income securities, money market instruments, overnight and fixed-term repurchase agreements, cash and other cash equivalents with maturities of one year or less to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct significant trading activity at or just prior to the close of the U.S. financial markets. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Counterparty Credit Risk – The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Fund’s investment.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Mid-Capitalization Securities Risk – The Fund is subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Portfolio Turnover Risk – The Fund’s strategy may frequently involve buying and selling portfolio securities, which may lead to increased costs to the Fund. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

Sector Risk – Because the Fund seeks to gain exposure to different industries and sectors in the economy, from time to time, it may invest a significant percentage of the Fund’s assets in issuers in a single industry or sector of the economy. To the extent the Fund has significant investment exposure to an industry or sector, such exposure may present more risks than if the Fund’s investments

were more broadly diversified. While the Fund’s sector and industry exposure is expected to vary over time, the Fund anticipates that it may be subject to some or all of the risks described below. The list below is not a comprehensive list of the sectors and industries the Fund may have exposure to over time and should not be relied on as such.

Basic Materials Sector Risk – To the extent that the Fund’s investments are focused in issuers conducting business in the basic materials sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the basic materials sector. The prices of the securities of basic materials companies also may fluctuate widely due to the level and volatility of commodity prices, the exchange value of the U.S. dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Energy Sector Risk – To the extent that the Fund’s investments are focused in the energy sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the energy and energy commodities sectors. The prices of the securities of energy companies also may fluctuate widely due to changes in value and dividend yield, which depend largely on the price and supply of energy fuels, international political events relating to oil producing countries, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies.

Financial Services Sector Risk – To the extent that the Fund’s investments are focused in issuers conducting business in the financial services sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of financial commitments they can make, and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. In addition, the recent deterioration of the credit markets generally has caused an adverse impact on a wide range of financial institutions and markets. Recent events in the financial sector have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and caused certain financial services companies to incur large losses.

Real Estate Sector Risk – To the extent that the Fund’s investments are focused in issuers conducting business in the real estate sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The general performance of the real estate industry has historically been cyclical and particularly sensitive to economic downturns. Changes in prevailing real estate values and rental income, interest rates and changing demographics may affect the value of securities of issuers in the real estate industry. Investments in real estate companies and REITs also may subject the Fund to the risks associated with the direct ownership of real estate. In addition to these risks, REITs are dependent on specialized management skills. These factors may increase the volatility of the Fund’s investments in REITs.

Technology Sector Risk – To the extent that the Fund’s investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology Companies also may fluctuate widely due to competitive pressures, increased sensitivity to short product cycles and aggressive pricing, problems relating to bringing their products to market, very high price/earnings ratios, and high personnel turnover due to severe labor shortages for skilled technology professionals.

Short Sales Risk – Short selling a security involves selling a borrowed security with the expectation that the value of the security will decline, so that the security may be purchased at a lower price when returning the borrowed security. The risk for loss on short selling is greater than the original value of the security sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect the Fund’s ability to engage in short selling.

Small-capitalization Securities Risk – The Fund is subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Trading Halt Risk – If a trading halt occurs, the Fund may temporarily be unable to purchase or sell certain securities, options or futures contracts. Such a trading halt near the time the Fund prices its shares may limit the Fund’s ability to use leverage and may prevent the Fund from achieving its investment objective.

The following bar chart shows the performance of the H-Class Shares of the Fund from year to year. The variability of performance over time provides an indication of the risks of investing in the Fund. The following table shows the average annual total returns of the H-Class Shares of the Fund over different periods of time in comparison to the performance of a broad-based market index. The figures in the bar chart and table assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Prior to May 28, 2010, the Fund did not employ hedging as a technique to achieve its objective; therefore, the performance and average annual total returns shown for periods prior to May 28, 2010 may have differed had the Fund’s current investment strategy been in effect during those periods.

Updated performance information is available on the Fund’s website at www.rydex-sgi.com or by calling Guggenheim Investments Client Services at 800.820.0888.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 2.73%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

Fund distributions are generally 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.

The Event Driven and Distressed Strategies Fund (the “Fund”) seeks to achieve capital growth.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 (including one year of capped expenses each period) remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 Total 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 513% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund’s investment methodology is based on a systematic algorithm developed through extensive quantitative research that is designed to select and weight a basket of six liquid, investable factors: small cap and distressed equities, high yield (or “junk”) bonds and credit, merger arbitrage and an illiquidity premium. In combination, these six factors seek to target return characteristics similar to those of the universe of event driven hedge funds. Event driven hedge funds seek to profit from potential mispricings of

the securities and the pricing spreads created by the risks related to a specific corporate transaction or market event. Such events can include: mergers, bankruptcies, financial or operational stress, restructurings, asset sales, recapitalizations, spin-offs, litigation, regulatory and legislative changes as well as other types of corporate events. Small cap equities, high yield bonds, and the equities of distressed companies combined with credit derivatives are a proxy for the primary instruments and exposures traded by distressed and opportunistic credit funds. A merger arbitrage index offers exposure to a liquid, diversified and broadly representative set of arbitrage positions on announced American and Western European merger and acquisition deals. The illiquidity factor seeks to represent the risk premium that may be achieved by holding illiquid securities. The factors and weights of those factors identified by the algorithm may change over time and may be long or short at any given time.

The Fund primarily seeks to obtain these exposures through swap agreements, but it also may invest in a combination of: domestic and foreign common stock; American Depositary Receipts (“ADRs”); credit or equity-linked instruments, primarily consisting of structured notes and exchange-traded notes (“ETNs”); exchange-traded funds (“ETFs”); other pooled investment vehicles; and other derivatives, primarily consisting of futures, options, and options on futures. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. The Fund’s use of derivatives and the leveraged investment exposure created by such use may be significant at times.

Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. From time to time, the Fund also may enter into short sales and invest in short positions of certain of its portfolio investments. The Fund may invest in derivatives to hedge or gain leveraged exposure to the components of a particular investable factor. On a day-to-day basis, the Fund may hold U.S. government securities, short-term, high quality (rated AA or higher) fixed income securities, money market instruments, overnight and fixed-term repurchase agreements, cash, and other cash equivalents with maturities of one year or less to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks.

In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund also may engage in frequent and active trading or portfolio investments to achieve its investment objective. The Fund is non-diversified and, therefore, may invest a greater percentage of its assets in a particular issuer in comparison to a diversified fund.

Counterparty Credit Risk – The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Fund’s investment.

Credit and Equity-Linked Derivative Investment Risk – The value of the Fund’s investment in these securities will rise or fall in response to changes in the underlying security or related benchmark or investment. These securities expose the Fund economically to movements in the prices of the underlying credit or equity security.

Exchange-Traded Notes Risk – The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities or securities markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced commodity or security. The Fund’s decision to sell its ETN holdings may also be limited by the availability of a secondary market. If the Fund must sell some or all of its ETN holdings and the secondary market is weak, it may have to sell such holdings at a discount. ETNs also are subject to counterparty credit risk and fixed income risk.

Investment Technique Risk – Some investment techniques of the Fund may be considered aggressive. Risks associated with the use of futures contracts, options, structured notes, and swap agreements include potentially dramatic price changes (losses) in the value of the instruments and imperfect correlations between the price of the contract and the underlying security or index. These instruments may increase the volatility of the Fund and may involve a small investment of cash relative to the magnitude of the risk assumed.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Small-Capitalization and Mid-Capitalization Securities Risk – The Fund is subject to the risk that small-and mid-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

The following bar chart shows the performance of the H-Class Shares of the Fund for the last calendar year. The variability of performance over time provides an indication of the risks of investing in the Fund. The following table shows the average annual total returns of the H-Class Shares of the Fund over different periods of time in comparison to the performance of a broad-based market index and the Credit Suisse Event Driven Liquid Index. The figures in the bar chart and table assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.rydex-sgi.com or by calling Guggenheim Investments Client Services at 800.820.0888.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 3.39%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

Fund distributions are generally 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.

The Long Short Equity Strategy Fund (the “Fund”) seeks to achieve long-term capital appreciation with less volatility than the S&P 500^® Index.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 983% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund’s investment methodology is based on a systematic and dynamic algorithm developed through extensive quantitative research that is designed to select and weight a basket of liquid, investable factors that, when combined, target return characteristics similar to those of the broad universe of long short equity hedge funds. Long short equity hedge funds typically buy stocks that the hedge fund managers expect will appreciate, and concurrently either sell short stocks that the hedge fund managers expect will decline in value or hedge market or sector exposures. The factors and weights of those factors identified by the algorithm may change over time and may be long or short at any given time. Potential factors include different market capitalization categories, growth, value, momentum, international, emerging markets, and various market sectors.

The Fund will seek to gain exposure to the factors selected by the algorithm by investing primarily in futures, options, options on futures, forward contracts, and swap agreements whose performance is expected to correspond to the performance of the factors. As a result, the Fund’s use of derivatives and the leveraged investment exposure created by such use is expected to be significant. The Fund also may invest in a combination of: domestic and foreign common stock; American Depositary Receipts (“ADRs”); credit or equity-linked instruments, primarily consisting of exchange-traded notes (“ETNs”) and structured notes; exchange-traded funds (“ETFs”); and other pooled investment vehicles. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also intends to enter into short sales and invest in short positions of certain of its portfolio investments. The Fund may invest in derivatives to hedge or gain leveraged exposure to the components of a particular investable factor. On a day-to-day basis, the Fund may hold U.S. government securities, short-term, high quality (rated AA or higher) fixed income securities, money market instruments, overnight and fixed-term repurchase agreements, cash, and other cash equivalents with maturities of one year or less to collateralize its derivative positions. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks.

Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in equity securities, and/or derivatives thereof. This is a non-fundamental policy that can be changed by the Fund upon 60 days’ prior notice to shareholders.

Counterparty Credit Risk – The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Fund’s investment.

Large-Capitalization Securities Risk – The Fund is subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Liquidity 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. In addition, the ability of the Fund to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.

The following bar chart shows the performance of the H-Class Shares of the Fund for the last calendar year. The variability of performance over time provides an indication of the risks of investing in the Fund. The following table shows the average annual total returns of the H-Class Shares of the Fund over different periods of time in comparison to the performance of a broad-based market index and the Credit Suisse Long/Short Liquid Index. The figures in the bar chart and table assume the reinvestment of dividends and capital gains distributions. Of course, this past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.rydex-sgi.com or by calling Guggenheim Investments Client Services at 800.820.0888.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 1.14%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

Fund distributions are generally 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.

The Long Short Interest Rate Strategy Fund (the “Fund”) seeks to maximize total return by taking advantage of price movements in the U.S. Treasury bond market.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 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 Total 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 0% of the average value of its portfolio. However, the Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund seeks to achieve its investment objective by investing in accordance with a highly quantitative investment model that is designed to identify a short-term interest rate outlook expressed in terms of exposure to the U.S. Treasury bond market. It is expected that the model will enable the Fund to potentially benefit from interest rate trends while also enabling it to take advantage of short-term deviations in such trends.

In executing this strategy, the Fund’s Sub-Advisor manages the investment model to determine an interest rate outlook. The model evaluates and ranks factors in 3 primary categories: (1) economic outlook based on various macro-economic factors; (2) inflationary expectations based on such factors as precious metals, commodities and other price movements; and (3) investor psychology as demonstrated by the level of market reaction not explained by the economic outlook and inflationary expectations. The interest rate outlook generated by the model determines the portfolio’s target duration ranging from fully bullish, with a target duration of approximately 11 years, to fully bearish, with a target duration of approximately negative 11 years. If the outlook is indeterminate, the Advisor will target a neutral portfolio duration of approximately 5.5 years. A neutral portfolio seeks to generate a return that is representative of the return of the overall Treasury market. Intermediate levels also may be established based on the interest rate outlook. The Sub-Advisor sends the model’s signals to the Advisor and the Advisor reviews the rate outlook determined by the model monthly to both manage risk and to seek to take advantage of short-term deviations in the general business cycle trend in interest rates.

On a day-to-day basis, the Fund invests substantially all of its net assets in cash, U.S. Treasury Bills, Notes, and Bonds as well as futures linked to those instruments, and exchange-traded funds (“ETFs”). The Fund also may invest in options, futures and swap

agreements to hedge the Fund’s exposure to U.S. Treasury securities and for non-hedging purposes, such as to manage the effective duration of the portfolio or as a substitute for direct investment. By focusing primarily on U.S. Treasury securities and Treasury-related futures and ETFs, the strategy minimizes or eliminates the risks (prepayment, currency, liquidity, etc.) inherent in many other fixed income management approaches. While the Fund anticipates investing in these instruments to seek to achieve its investment objective, the extent of the Fund’s investment in these instruments may vary from day to day depending on a number of different factors, including price, availability, and general market conditions. The Fund’s use of derivatives and the leveraged investment exposure created by such use may be significant at times. In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks. The Fund also may engage in frequent and active trading or portfolio investments to achieve its investment objective.

Counterparty Credit Risk – The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Fund’s investment.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is -2.46%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

American Independence Financial Services, LLC serves as the investment sub-adviser of the Fund.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

Fund distributions are generally 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.

The All-Asset Conservative Strategy Fund (the “Fund”) seeks to primarily provide preservation of capital and, secondarily, long-term growth of capital.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 Fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or “turns over” its portfolio). The underlying funds do pay transaction costs when they turn over their portfolio, and a higher portfolio turnover rate may indicate higher transactions costs. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the performance of the underlying funds and of the Fund. During the most recent fiscal year, the Fund’s portfolio turnover rate was 134% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund seeks to achieve its investment objective by investing principally in a diversified portfolio of underlying funds that represent traditional asset classes, such as stocks, bonds and money market securities, a broad range of alternative assets, such as real estate investment trusts (“REITs”) and commodity-related securities, and alternative investment strategies, such as absolute return, managed futures, and leveraged and sector-based strategies, in an attempt to improve risk-adjusted returns and lower portfolio volatility. The Fund will typically have a conservative allocation to underlying funds that invest in stocks, and a greater allocation to underlying funds that invest in bonds and money market securities as compared to the other Asset Allocation Funds. The Advisor may change the Fund’s asset class allocation, the underlying funds, or weightings without shareholder notice.

The Fund may invest in, and thus have indirect exposure to the risks of, the underlying funds listed below. Unless otherwise noted, each underlying fund listed below is a series of the Trust.

The Fund also may invest in exchange-traded funds (“ETFs”), other pooled investment vehicles, and derivatives, primarily consisting of index swaps, futures contracts, and options on securities, futures contracts and indices to enable the Fund to pursue its investment objective efficiently in gaining or hedging exposure to various market factors or to better manage its risk and cash positions. Certain of the Fund’s derivative investments may be traded in the over-the-counter (“OTC”) market. The Fund also may enter into repurchase agreements with counterparties that are deemed to present acceptable credit risks.

In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets.

Commodity-Linked Derivative Investment Risk – The value of a commodity-linked derivative investment typically is based upon the price movements of a physical commodity (such as heating oil, livestock, or agricultural products), a commodity futures contract or commodity index, or some other readily measurable economic variable dependent upon changes in the value of commodities or the commodities markets. The value of these investments will rise or fall in response to changes in the underlying commodity or related benchmark or investment. These investments expose the Fund economically to movements in commodity prices.

Conflicts of Interest Risk – The Advisor will have the authority to select and substitute underlying funds. The Advisor is subject to conflicts of interest in doing so and when it allocates Fund assets among the various underlying funds, both because the fees payable to it by some underlying funds may be higher than the fees payable by other underlying funds and because the Advisor also may be responsible for managing affiliated underlying funds.

Counterparty Credit Risk – The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to an underlying fund or the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Fund’s investment.

Credit Risk – The Fund and certain of the underlying funds could lose money if the issuer or guarantor of a debt instrument in which the Fund or underlying fund invests becomes unwilling or unable to make timely principal and/or interest payments, or to otherwise meet its obligations.

Currency Risk – The Fund’s and certain of the underlying funds’ indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in interest rates and the imposition of currency controls or other political developments in the U.S. or abroad. In particular, certain of the underlying funds, and thus the Fund, may have indirect and direct exposure to the euro. The price of euro has fluctuated widely over the past several years, and volatility has increased in recent months, due, in part, to concern over the sovereign debt levels of certain European Union (EU) members and the potential effect of this debt on the EU members’ participation in the European Monetary Union and the value of the euro. These and other factors may adversely affect the long-term value of the euro in terms of purchasing power in the future. A decline in the price of the euro may adversely affect the Fund’s performance.

Derivatives Risk – The Fund’s investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, lack of availability and counterparty risk. The Fund’s investments in underlying funds that invest in derivatives also subject the Fund to these risks.

Exchange-Traded Notes (ETNs) Risk – Certain of the underlying funds may invest in ETNs. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities or securities markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced commodity or security. An underlying fund’s decision to sell its ETN holdings also may be limited by the availability of a secondary market. If the underlying fund must sell some or all of its ETN holdings and the secondary market is weak, it may have to sell such holdings at a discount. ETNs also are subject to counterparty credit risk and fixed income risk.

Fixed Income Risk – An underlying fund’s investments in fixed income securities will change in value in response to interest rate changes and other factors, such as the perception of the issuer’s creditworthiness. For example, the value of fixed income securities will generally decrease when interest rates rise, which may indirectly affect the Fund and cause the value of the Fund to decrease. In addition, an underlying fund’s investments in fixed income securities with longer maturities will fluctuate more in response to interest rate changes.

Foreign Issuer Exposure Risk – The Fund and certain of the underlying funds may invest in securities of foreign companies directly or in financial instruments that are indirectly linked to the performance of foreign issuers. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of securities traded on U.S. markets.

Fund of Funds Risk – By investing in the underlying funds indirectly through the Fund, an investor will incur not only a proportionate share of the expenses of the underlying funds held by the Fund (including operating costs and management fees), but also expenses of the Fund. Consequently, an investment in the Fund entails more direct and indirect expenses than a direct investment in the underlying funds.

Geographic Concentration in Europe Risk – Because a significant portion of the assets of certain of the underlying funds investments are concentrated in issuers located in Europe, the Fund is susceptible to loss due to adverse market, political, regulatory, and geographic events affecting the various countries and regions in Europe. The European economy is diverse and includes both large, competitive economies and small, struggling economies. The European economy is vulnerable to decreasing imports or exports, changes in governmental regulations on trade, changes in the exchange rate of the euro and recessions in EU economies.

Geographic Concentration in Japan Risk – Targeting Japan could hurt certain of the underlying funds’ performance if Japan’s economy performs poorly as a result of political and economic conditions that affect the Japanese market.

High Yield Risk – Certain of the underlying funds may invest in high yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), which may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities.

Income Risk – Income risk involves the potential for a decline in the yield of certain of the Fund’s investments, including stocks, bonds, ETFs, and Unit Investment Trusts (“UITs”). For example, interest and/or dividend income produced by certain of the Fund’s investments will vary over time, which may cause the Fund’s value to fluctuate.

Interest Rate Risk – The market value of fixed income investments and related financial instruments will change in response to interest rate changes. During periods of falling interest rates, the values of fixed income securities generally rise. Conversely, during periods of rising interest rates, the values of such securities generally decline.

Investment in the Subsidiary Risk – Certain of the underlying funds may invest in wholly-owned and controlled Cayman Islands subsidiaries (each, a “Subsidiary” and together, the “Subsidiaries.”) The Subsidiaries are not registered under the Investment Company Act of 1940 (the “1940 Act”) and, unless otherwise noted in this Prospectus, are not subject to all of the investor protections of the 1940 Act. Thus, certain of the underlying funds, as the sole investor in their respective Subsidiaries, will not have all of the protections offered to shareholders of registered investment companies. By investing in the Subsidiaries, certain of the underlying funds are exposed to the risks of the Subsidiaries’ investments, which in turn will be exposed primarily to the risks of investing in the commodities markets. Each applicable underlying fund also will incur its pro rata share of the expenses of its Subsidiary. In addition, changes in the laws of the United States or the Cayman Islands, under which certain of the underlying funds and the Subsidiaries, respectively, are organized, could result in the inability of the underlying funds and/or the Subsidiaries to operate as intended and could negatively affect the Fund and its shareholders.

Investment Technique Risk – Some investment techniques of the Fund and certain of the underlying funds, such as the Fund’s and underlying funds’ use of derivatives and other commodity-linked financial instruments to seek to achieve their respective investment objectives, may be considered aggressive. These instruments may increase the volatility of the Fund and certain of the underlying funds and may involve a small investment of cash relative to the magnitude of the risk assumed. Such investment techniques may not consistently produce desired results and may be limited by legislative, regulatory, or tax developments.

Issuer Specific Risk – A decrease in the value of the securities of an issuer or guarantor of a debt instrument held by the Fund or certain underlying funds may cause the value of your investment in the Fund to decrease. The value of a security may increase or decrease for a number of reasons which directly relate to the issuer.

Large-Capitalization Securities Risk – The Fund and certain of the underlying funds are subject to the risk that large-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Leveraging Risk –The Fund achieves leveraged exposure generally, and certain of the underlying funds achieve leveraged exposure to their respective benchmarks or underlying indices through the use of derivative instruments. The Fund’s and underlying funds’ investment in these instruments generally requires a small investment relative to the amount of investment exposure assumed. As a result, such investments may give rise to losses that exceed the amount invested in those instruments. The more the Fund or an underlying fund invests in leveraged instruments, the more this leverage will magnify any losses on those investments. Because the use of such instruments may be an integral part of certain underlying funds’ investment strategies, the use of such instruments may expose the underlying fund and thus, the Fund, to potentially dramatic losses or gains in the value of their respective portfolios. Leverage also will have the effect of magnifying tracking error.

Liquidity Risk – In certain circumstances, it may be difficult for the Fund and certain of the underlying funds to purchase and sell particular investments within a reasonable time at a fair price. While the Fund and underlying funds only intend to invest in liquid futures, options, forwards and swap contracts, under certain market conditions, such as when the market makes a “limit move,” it may be difficult or impossible for the Fund or an underlying fund to liquidate such investments. In addition, the ability of the Fund and certain of the underlying funds to assign an accurate daily value to certain investments may be difficult, and the Advisor may be required to fair value the investments.

Mid-Capitalization Securities Risk – The Fund and certain of the underlying funds are subject to the risk that medium-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

OTC Trading Risk – Certain of the derivatives in which the Fund and certain of the underlying funds may invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.

Sector Risk – Through its investment in certain underlying funds, the Fund may be subject to the following The Sector Risk:

Agriculture Sector Risk – Through their investments in futures and similar instruments, certain of the underlying funds may have significant exposure to the agriculture sector. As a result of this investment exposure, the underlying funds, and thus the Fund, will be more susceptible to the risks associated with the agriculture sector than a fund that does not invest in such a manner. To the extent that an underlying fund has significant exposure to the agriculture sector, the underlying fund, and thus the Fund, is subject to the risk that the agriculture sector will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector.

Basic Materials Sector Risk – To the extent that certain of the underlying funds’ investments are focused in issuers conducting business in the basic materials sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the basic materials sector. The prices of the securities of basic materials companies also may fluctuate widely due to the level and volatility of commodity prices, the exchange value of the U.S. dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Energy Sector Risk – To the extent that certain of the underlying funds’ investments are focused in the energy sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the energy and energy commodities sectors. The prices of the securities of energy companies also may fluctuate widely due to changes in value and dividend yield, which depend largely on the price and supply of energy fuels, international political events relating to oil producing countries, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies.

Financial Services Sector Risk – To the extent that certain of the underlying funds’ investments are focused in issuers conducting business in the financial services sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of financial commitments they can make, and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. In addition, the recent deterioration of the credit markets generally has caused an adverse impact on a wide range of financial institutions and markets. Recent events in the financial sector have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and caused certain financial services companies to incur large losses.

Real Estate Sector Risk – To the extent that certain of the underlying funds’ investments are focused in issuers conducting business in the real estate sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The general performance of the real estate industry has historically been cyclical and particularly sensitive to economic downturns. Changes in prevailing real estate values and rental income, interest rates and changing demographics may affect the value of securities of issuers in the real estate industry. Investments in real estate companies and REITs also may subject the Fund to the risks associated with the direct ownership of real estate. In addition to these risks, REITs are dependent on specialized management skills. These factors may increase the volatility of the Fund’s investments in REITs.

Technology Sector Risk – To the extent that certain of the underlying funds’ investments are concentrated in issuers conducting business in the technology sector, the Fund is subject to the risk that the securities of such issuers will underperform the market as a whole due to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology Companies also may fluctuate widely due to competitive pressures, increased sensitivity to short product cycles and aggressive pricing, problems relating to bringing their products to market, very high price/earnings ratios, and high personnel turnover due to severe labor shortages for skilled technology professionals.

selling is greater than the original value of the securities sold short because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. Government actions also may affect certain of the underlying funds’ ability to engage in short selling.

Small-Capitalization Securities Risk – The Fund and certain of the underlying funds are subject to the risk that small-capitalization stocks may underperform other segments of the equity market or the equity market as a whole.

Stable Price Per Share Risk – Certain of the underlying funds’ assets are valued using the amortized cost method, which enables the underlying fund to maintain a stable price of $1.00 per share. Although the underlying fund is managed to maintain a stable price per share of $1.00, there is no guarantee that the price will be constantly maintained and it is possible to lose money.

Tax Risk – Certain of the underlying funds currently gain most of their exposure to the commodities markets through their investments in wholly-owned subsidiaries which may invest in commodity-linked derivative instruments and other similar instruments in compliance with private letter rulings issued by the Internal Revenue Service to certain of the underlying funds. To the extent the an affiliated underlying fund invests in such instruments directly, it intends to restrict its income from commodity-linked derivative instruments that do not generate qualifying income, such as commodity-linked swaps, to a maximum of 10% of its gross income, to comply with certain qualifying income tests necessary for the Fund to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended.

Tracking Error Risk – The Advisor may not be able to cause certain of the underlying funds’ performance to match or correlate to that of the underlying funds’ respective underlying index or benchmark, either on a daily or aggregate basis. Factors such as underlying fund expenses, imperfect correlation between an underlying fund’s investments and those of its underlying index or underlying benchmark, rounding of share prices, changes to the composition of the underlying index or underlying benchmark, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause an underlying fund’s and, thus the Fund’s, performance to be less than you expect.

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.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 3.71%.

The after-tax returns presented in the table below are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold shares of the Fund through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

Fund distributions are generally 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.

The All-Asset Moderate Strategy Fund (the “Fund”) seeks to primarily provide growth of capital and, secondarily, preservation of capital.

This table describes the fees and expenses that you may pay if you buy and hold H-Class Shares of the Fund.

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 Fund, which operates as a fund of funds and invests in underlying funds, does not pay transaction costs, such as commissions, when it buys and sells shares of underlying funds (or “turns over” its portfolio). The underlying funds do pay transaction costs when they turn over their portfolio, and a higher portfolio turnover rate may indicate higher transactions costs. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the performance of the underlying funds and of the Fund. During the most recent fiscal year, the Fund’s portfolio turnover rate was 77% of the average value of its portfolio. The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

volatility. The Fund will typically have a moderate allocation to underlying funds that invest in stocks, and a moderate allocation to underlying funds that invest in bonds as compared to the other Asset Allocation Funds. The Advisor may change the Fund’s asset class allocation, the underlying funds, or weightings without shareholder notice.

The Fund may invest in, and thus have indirect exposure to the risks of, the following underlying funds and unless otherwise noted, each underlying fund listed below is a series of the Trust:

In an effort to ensure that the Fund is fully invested on a day-to-day basis, the Fund may conduct any necessary trading activity at or just prior to the close of the U.S. financial markets.

Counterparty Credit Risk – The Fund may invest in financial instruments involving counterparties that attempt to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. The Fund’s use of such financial instruments, including swap agreements and structured notes, involves risks that are different from those associated with ordinary portfolio securities transactions. For example, if a swap agreement counterparty defaults on its payment obligations to an underlying fund or the Fund, this default will cause the value of your investment in the Fund to decrease. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Fund’s investment.

this debt on the EU members’ participation in the European Monetary Union and the value of the euro. These and other factors may adversely affect the long-term value of the euro in terms of purchasing power in the future. A decline in the price of the euro may adversely affect the Fund’s performance.

Derivatives Risk – The Fund’s investments in derivatives may pose risks in addition to those associated with investing directly in securities or other investments, including illiquidity of the derivatives, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, lack of availability and counterparty risk. The Fund’s investments in underlying funds that invest in derivatives also subject the Fund to these risks.

The Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund seeks to achieve its investment objective by investing principally in a diversified portfolio of underlying funds that represent traditional asset classes, such as stocks, bonds and money market securities, a broad range of alternative assets, such as real estate investment trusts and commodity-related securities, and alternative investment strategies, such as absolute return, managed futures, and leveraged and sector-based strategies, in an attempt to improve risk-adjusted returns and lower portfolio volatility. The Fund will typically have an aggressive allocation to underlying funds that invest in stocks, and a lower allocation to underlying funds that invest in bonds as compared to the other Asset Allocation Funds. The Advisor may change the Fund’s asset class allocation, the underlying funds, or weightings without shareholder notice.

Sector Risk – Through its investment in certain underlying funds, the Fund may be subject to the following The Sector Risk:

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.

The performance information shown below for H-Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 5.62%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

The minimum initial investment amounts for H-Class accounts held through a third party (e.g., a brokerage account) are:

Fund distributions are generally 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.

The U.S. Government Money Market Fund (the “Fund”) seeks to provide security of principal, high current income, and liquidity.

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

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 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 Total 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 0% of the average value of its portfolio. However, the Fund’s portfolio turnover rate is calculated without regard to cash instruments or derivatives. If such instruments were included, the Fund’s portfolio turnover rate might be significantly higher.

The Fund invests primarily in money market instruments issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities, and enters into repurchase agreements collateralized fully by U.S. government securities. The Fund also may invest in other securities that are determined to be “Eligible Securities” as defined in Rule 2a-7 of the Investment Company Act of 1940 (the “1940 Act”), including, but not limited to Eurodollar Time Deposits, securities issued by the International Bank for Reconstruction and Development (also known as The World Bank), and high-quality commercial paper certificates of deposit, and short-term corporate bonds. The Fund operates in compliance with U.S. Securities and Exchange Commission (the “SEC”) rules, including Rule 2a-7, which impose certain liquidity, maturity and diversification requirements on all registered money market funds. All securities purchased by the Fund must have remaining maturities of 397 days or less, and must be found by the Advisor to represent minimal credit risk and be of eligible quality.

Under normal circumstances, the Fund will invest at least 80% of its net assets, plus any borrowings for investment purposes, in government securities as defined by Section 2(a)(16) of the 1940 Act (and derivatives thereof). Section 2(a)(16) of the 1940 Act defines “government security” to mean any security issued or guaranteed as to principal or interest by the United States, or by a person controlled or supervised by and acting as an instrumentality of the government of the United States pursuant to authority granted by the Congress of the United States; or any certificate of deposit for any of the foregoing.

Income Risk – Income Risk involves the potential for decline in the Fund’s yield (the rate of dividends the Fund pays) in the event of declining interest rates.

Repurchase Agreement Risk – The Fund’s investment in repurchase agreements may be subject to market and credit risk with respect to the repurchase agreement counterparty and underlying collateral securing the repurchase agreements. Investments in repurchase agreements also may be subject to the risk that the market value of the underlying obligations may decline prior to the expiration of the repurchase agreement term.

Stable Price Per Share Risk – The Fund’s assets are valued using the amortized cost method, which enables the Fund to maintain a stable price of $1.00 per share. Although the Fund is managed to maintain a stable price per share of $1.00, there is no guarantee that the price will be constantly maintained, and it is possible to lose money.

Effective upon the close of business on June 15, 2012, the Fund converted its existing Investor Class Shares, Advisor Class Shares, A-Class Shares, C-Class Shares and Investor2 Class Shares with a single share class. Therefore, the returns shown in the bar chart below for all periods are the returns of the Fund’s former Investor Class Shares, which were subject to the same fees and expenses as the shares offered in this Prospectus. The Fund’s shares would have annual returns substantially similar to those of the former Investor Class Shares because they are invested in the same portfolio of securities. The variability of performance over time provides an indication of the risks of investing the Fund. Of course, this past performance (before taxes) does not necessarily indicate how the Fund will perform in the future.

Updated performance information is available on the Fund’s website at www.rydex-sgi.com or by calling Guggenheim Investments Client Services at 800.820.0888.

The performance information shown below for the Fund’s former Investor Class Shares is based on a calendar year. The year-to-date return for the period from January 1, 2012 through June 30, 2012 is 0.00%.

Security Investors, LLC, which operates under the name Guggenheim Investments, serves as the investment adviser of the Fund.

Shares held either directly with Guggenheim Investments or through a third party (e.g., a brokerage account) are not subject to a minimum initial investment amount or a minimum account balance. However, if you exchange shares of the Fund for shares of another fund in the Guggenheim Investments family of funds you will be subject to the purchaser eligibility requirements of the applicable share class of that fund, which may include initial investment amount and account balance requirements. Any such requirements will be disclosed in each fund’s prospectus. In addition, accounts opened through a financial intermediary (non-direct) may be subject to that financial intermediary’s minimum initial investment amount and account balance requirements.

The Fund reserves the right to accept orders to purchase or redeem shares on any day that is not a Business Day and the Federal Reserve Bank of New York or National Securities Clearing Corporation remains open. In addition, the Fund may designate special hours of operation on any such day. In the event that the Fund invokes the right to accept orders to purchase or redeem shares on any day that is not a Business Day and/or adopt special hours of operation, the Fund will post advance notice of these events at www.rydex-sgi.com.

Fund distributions are generally 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.

The investment objective of each Fund is non-fundamental and may be changed without shareholder approval.

The following sections provide additional information regarding certain of the Funds’ investment objectives.

Each Domestic Equity Fund, International Equity Fund, Specialty Fund (except the Real Estate Fund), and Fixed Income Fund (except the High Yield Strategy Fund and Inverse High Yield Strategy Fund) may change its underlying index or benchmark without shareholder approval. The Advisor, however, will attempt to provide shareholders with 30 days’ prior notice of any such change.

Emerging Markets 2x Strategy Fund and Strengthening Dollar 2x Strategy Fund. If the Fund meets its investment objectives the value of the Fund’s shares will tend to increase on a daily basis by 200% of any increase in the value of the Fund’s underlying index (e.g., if the value of the underlying index goes up by 5%, the value of the Fund’s shares should go up by 10% on that day). When the value of the Fund’s underlying index declines, the value of the Fund’s shares should also decrease on a daily basis by 200% of any decrease in the value of the underlying index (e.g., if the value of the underlying index goes down by 5%, the value of the Fund’s shares should go down by 10% on that day).

Inverse Emerging Markets 2x Strategy Fund and Weakening Dollar 2x Strategy Fund. If the Fund meets its investment objective, the value of the Fund’s shares will tend to increase on a daily basis by 200% of any decrease in the value of the Fund’s underlying index (e.g., if the value of the Fund’s underlying index goes down by 5%, the value of the Fund’s shares should go up by 10% on that day).When the value of the Fund’s underlying index increases, the value of the Fund’s shares should decrease on a daily basis by 200% of any increase in the value of the underlying index (e.g., if the value of the Fund’s underlying index goes up by 5%, the value of the Fund’s shares should go down by 10% on that day).

Inverse Mid-Cap Strategy, Inverse NASDAQ-100^® Strategy, Inverse Russell 2000^® Strategy and Inverse S&P 500 Strategy Funds. If the Fund meets its investment objective, the value of the Fund’s shares will tend to increase during times when the value of the Fund’s underlying index is decreasing. When the value of the Fund’s underlying index is increasing, however, the value of the Fund’s shares should decrease on a daily basis by an inversely proportionate amount (e.g., if the index goes up by 5%, the value of the Fund’s shares should go down by 5% on that day).

Mid-Cap 1.5x Strategy, Russell 2000^® 1.5x Strategy and Europe 1.25x Strategy Funds. If the Fund meets its investment objective, the value of the Fund’s shares will tend to increase during times when the performance of the Fund’s underlying index is increasing. When the value of the Fund’s underlying index is decreasing, the value of the Fund’s shares will tend to decrease.

Nova Fund. If the Fund meets its investment objective, the value of the Fund’s shares will tend to increase on a daily basis by 150% of any increase in the value of the underlying index. When the value of the underlying index declines, the value of the Fund’s shares should also decrease on a daily basis by 150% of any decrease in the value of the underlying index (e.g., if the value of the underlying index goes down by 5%, the value of the Fund’s shares should go down by 7.5% on that day).

NASDAQ-100^®, Russell 2000^®, S&P 500, S&P 500 Pure Growth, S&P 500 Pure Value, S&P MidCap 400 Pure Growth, S&P MidCap 400 Pure Value, S&P SmallCap 600 Pure Growth, and S&P SmallCap 600 Pure Value Funds. If the Fund meets its investment objective, the value of the Fund’s shares will tend to increase on a daily basis by the percentage of any increase in the value of the Fund’s underlying index. When the value of the Fund’s underlying index declines, the value of the Fund’s shares should also decrease on a daily basis by the percentage of the decrease in value of the underlying index.

Japan 2x Strategy Fund. If the Fund meets its investment objective, the value of the Fund’s shares will tend to increase by 200% of the fair value of the underlying index during times when the performance of the underlying index is increasing. When the fair value of the Fund’s underlying index decreases, the value of the Fund’s shares should also decrease by 200% of the fair value of the decrease in the underlying index (e.g., if the fair value of the underlying index goes down by 5%, the value of the Fund’s shares should go down by 10%). Due to the use of fair valuation, which is explained in more detail under “Calculating NAV,” the value of the Fund’s shares may increase by more or less than 200% of the reported value of the underlying index on any given day.

Government Long Bond 1.2x Strategy Fund. If the Fund meets its investment objective, the value of the Fund’s shares should increase on a daily basis by 120% of any price increase by the Long Treasury Bond. In contrast, when the price of the Long Treasury Bond declines, the value of the Fund’s shares should decline on a daily basis by 120% of any price decline of the Long Treasury Bond (e.g., if the Long Treasury Bond goes down by 5%, the value of the Fund’s shares should go down by 6% on that day).

Inverse Government Long Bond Strategy Fund. If the Fund meets its investment objective, the value of the Fund’s shares will tend to increase on a daily basis when the price of the Long Treasury Bond decreases. When the price of the Long Treasury Bond increases, however, the value of the Fund’s shares should decrease on a daily basis by an inversely proportionate amount (e.g., if the price of the Long Treasury Bond increases by 2%, the value of the Fund’s shares should go down by 2% on that day).

Inverse High Yield Strategy Fund. If the Fund meets its investment objective, the value of the Fund’s shares will tend to increase during times when the value of the high yield bond market, as a whole, is decreasing. When the value of the high yield bond market is increasing, however, the value of the Fund’s shares should decrease on a daily basis by an inversely proportionate amount (e.g., if the value of the high yield bond market increases by 5%, the value of the Fund’s shares should decrease by 5% on that day).

The Advisor develops and implements structured investment strategies designed to achieve each Fund’s investment objective. The Advisor places particular emphasis on controlling risk relative to each Fund’s benchmark or market sector in order to maintain consistency and predictability.

With the exception of the Alternatives Funds, High Yield Strategy Fund, Inverse High Yield Strategy Fund and Asset Allocation Funds, the Advisor does not engage in temporary defensive investing, keeping each Fund fully invested in all market environments. The Alternatives Funds, High Yield Strategy Fund, Inverse High Yield Strategy Fund and Asset Allocation Funds may, but will not necessarily, invest up to 100% of its assets in high-quality money market instruments in order to protect the value of the Fund in response to adverse economic, political or market conditions. This strategy, if employed, could result in lower returns and loss of market opportunity. Thus, when pursuing a temporary defensive strategy, the Alternatives Funds, High Yield Strategy Fund, Inverse High Yield Strategy Fund and Asset Allocation Funds may not achieve their respective investment objectives.

Each Domestic Equity Fund’s, Sector Fund’s, International Equity Fund’s, Fixed Income Fund’s, and the Real Estate Fund’s and U.S. Government Money Market Fund’s investment policy to invest at least 80% of its net assets in a particular type of investment or security is a non-fundamental policy that can be changed by the Fund upon 60 days’ prior notice to shareholders.

Domestic Equity Funds, International Equity Funds, Specialty Funds (except for the Real Estate Fund), and Fixed Income Funds (except for the High Yield Strategy Fund and Inverse High Yield Strategy Fund). In managing the Funds, the Advisor uses a “passive” investment strategy to manage each Fund’s portfolio, meaning that the Advisor does not attempt to select securities based on their individual potential to perform better than the market. The Advisor’s primary objective for the Funds is to match or correlate as closely as possible with the performance of each Fund’s underlying index or other benchmark. The Advisor uses

quantitative analysis techniques to structure each Fund to obtain the highest correlation to its particular benchmark. The Advisor monitors each Fund on an ongoing basis, and makes adjustments to its portfolio, as necessary, to minimize tracking error and to maximize liquidity.

The following Funds – Mid-Cap 1.5x Strategy Fund, Nova Fund, Russell 2000^® 1.5x Strategy Fund, Europe 1.25x Strategy Fund, Japan 2x Strategy Fund, Emerging Markets 2x Strategy Fund, Government Long Bond 1.2x Strategy Fund, Strengthening Dollar 2x Strategy Fund, and Weakening Dollar 2x Strategy Fund – are invested to achieve returns that exceed the returns of the indices underlying their benchmarks. These leveraged returns are achieved not by borrowing, but by the use of futures contracts and options on securities, futures contracts, and stock indices, and other instruments that simulate leveraged returns without requiring a commitment of cash in excess of the Fund’s assets. For the Inverse Mid-Cap Strategy Fund, Inverse NASDAQ-100^® Strategy Fund, Inverse Russell 2000^® Strategy Fund, Inverse S&P 500 Strategy Fund, Inverse Emerging Markets 2x Strategy Fund, Weakening Dollar 2x Strategy Fund, and Inverse Government Long Bond Strategy Fund, the Advisor uses short selling techniques to produce returns that move inversely to the performance of their respective underlying indices.

Sector and Real Estate Funds. In managing the Sector Funds and the Real Estate Fund, the Advisor’s objective is to develop a liquid portfolio of stocks that effectively represents a particular economic segment of the market. Because appropriate published indices are not available for many of the Sector Funds and the Real Estate Fund, the Advisor has developed its own methodology to construct objective performance benchmarks. The Advisor first identifies the investment universe for each sector using Global Industry Classification Standard (GICS) codes. The Advisor then employs a quantitative screen to ensure minimum capitalization and liquidity standards. The resulting portfolio is weighted to meet diversification standards and to generate returns respective of that sector. The Advisor monitors the efficacy of this methodology, and makes periodic changes in the composition of the Sector and Real Estate Funds to ensure that each Fund remains a valid representation of its sector.

Alternatives Funds. While the Alternatives Funds seek to target return characteristics similar to those achieved by certain hedge fund strategies, the Alternatives Funds are registered investment companies and, thus, are subject to the comprehensive regulatory scheme of the 1940 Act and other federal securities laws. As a result, the Alternatives Funds are not permitted to engage in certain investment activities to the same extent as hedge funds, such as borrowing and leverage. Therefore, the Alternatives Funds may seek to achieve their investment objectives through the use of investment techniques that differ from those employed by hedge funds.

U.S. Long Short Momentum Fund. Each month, the Advisor ranks all industries according to several measures of price momentum. The top-ranked industries are selected for the Advisor’s buy list. In order to ensure liquidity in the underlying securities for purchase, approximately 2,000 securities are eligible for purchase from the industry buy lists. The Advisor uses this methodology to rotate the Fund’s investments among a variety of industries or sectors in order to take advantage of volatility in the top performing sectors. The Fund may, at times, also short-sell securities in industries or sectors that exhibit particularly low momentum measurement scores. The Advisor may invest in cash or cash-type securities (high-quality, short-term debt securities issued by corporations, financial institutions, the U.S. government or foreign governments) as a temporary defensive position to avoid losses during adverse market conditions. Taking a temporary defensive position could reduce the benefit to the Fund if the market goes up. In this case, the Fund may not achieve its investment goal.

Event Driven and Distressed Strategies Fund. The Event Driven and Distressed Strategies Fund seeks to provide investment results that generally correspond to the performance of the event driven hedge fund universe. Event driven hedge funds invest in various asset classes, including physical commodities and real estate, and seek to profit from potential mispricings of securities related to a specific corporate or market event. Such events can include: mergers, bankruptcies, financial or operational stress, restructurings, asset sales, recapitalizations, spin-offs, litigation, regulatory and legislative changes as well as other types of corporate events. Event driven hedge funds can invest in equities, fixed income instruments (investment grade, high yield, bank, convertible and distressed debt), options and various other derivatives. Event driven hedge funds may specialize in distressed debt, distressed equities, Regulation D transactions, capital structure arbitrage, merger arbitrage or other special situations. Many managers use a combination of strategies that typically involve buying long or selling short certain securities in the capital structures of various corporations representing a broad range of both debt and equity securities and adjust exposures based on the opportunity sets in each sub-sector.

Long Short Equity Strategy Fund. The Long Short Equity Strategy Fund seeks to provide investment exposure similar to that provided by a broad universe of long short equity hedge funds. Long short equity strategies employed by hedge funds vary greatly in style and investment approach. They may be: net long, net short, or market neutral; highly diversified or concentrated; global or single country focused; broad-based or concentrated on specific industries; or long-biased, hedged, or short-biased.

Long Short Interest Rate Strategy Fund. The Long Short Interest Rate Strategy Fund’s investment model uses a statistically-based process that analyzes economic factors together with the judgments of investor psychology to determine an interest rate outlook. The Sub-Advisor is responsible for constructing a model and providing the Advisor with the signals generated by the model, the methodology of which is grounded in the basic economic theory of interest rate behavior and combines measures of economic growth and inflation expectations to identify cyclical interest rate trends. Technical factors are incorporated into the methodology to identify and opportunistically capture the overshooting that interest rates frequently exhibit.

The factors used in the model are selected based on the following three criteria: (1) quantitative significance in explaining the volatility of interest rates; (2) scenario simulations to evaluate the factor’s contribution to performance when simulated over a significant time period against changes in the levels of economic activity; and (3) judgment with regard to the factor’s conceptual plausibility based on the fundamentals and the behavior of interest rates over the economic cycle. The Sub-Advisor will continuously manage the model and the model’s signals will contain such information necessary for the Advisor to implement the Long Short Interest Rate Strategy Fund’s investment strategy.

High Yield Strategy and Inverse High Yield Strategy Funds. The Advisor’s primary objective for the High Yield Strategy Fund and Inverse High Yield Strategy Fund is to correlate with the performance of the high yield bond market. The Advisor seeks to create portfolios that will correlate highly with the performance of the high yield bond market by investing in credit default swaps, bond futures and other financial instruments that have risk and return characteristics similar to a portfolio of high yield securities. A high yield bond is a bond that is rated below investment grade. Generally, high yield bonds are those bonds rated BB+ and lower by Standard & Poor’s Rating Service or Ba1 and lower by Moody’s Investor Services, Inc. Investors are subject to credit risk when investing in high yield bonds as issuers of the debt may be unable to make their interest and principal payments. High yield bonds typically pay higher yields because they tend to have a higher risk of defaulting than investment grade bonds. Investors are also subject to interest rate risk when investing in high yield bonds as fixed income securities will generally decrease when interest rates rise. However, the prices of high yield bonds may not necessarily move inversely with changes in interest rates due to changes in credit risk and/or other risks. The Funds will primarily invest in credit default swaps to gain exposure similar to the high yield bond market. A seller of credit default swaps is selling credit protection or assuming credit risk. A buyer of credit default swaps is buying credit protection or mitigating credit risk. The High Yield Strategy Fund will generally be a seller of credit protection and the Inverse High Yield Strategy Fund will generally be a buyer of credit protection. To manage interest rate risk, the Funds invest in bond futures. The High Yield Strategy Fund will typically buy bond futures, whereas the Inverse High Yield Strategy Fund will typically sell bond futures short. Additionally, the Advisor evaluates the relative liquidity of underlying securities to determine the optimal mix of assets for each Fund.

Asset Allocation Funds. Each Fund is a “fund of funds,” which means that each Fund seeks to achieve its investment objective by investing primarily in a combination of funds within the same group of affiliated investment companies, the Guggenheim Investments family of funds (collectively, the “underlying funds”), which are advised by the Advisor and in ETFs instead of in individual securities.

In managing the Asset Allocation Funds, the Advisor uses many of the tenets of Essential Portfolio Theory (“EPT”), an investment theory developed by the Advisor. The theory is based upon a disciplined and diversified approach to investing that attempts to take into account the various factors that influence today’s financial markets. EPT attempts to maximize returns for a benchmark-targeted level of risk by investing each Fund’s assets in underlying funds comprised of equities, fixed income and money market instruments, alternative asset classes, and alternative investment strategies.

In seeking to achieve the goal of maximizing returns for each Fund’s risk level, the Advisor uses quantitative analysis to efficiently allocate across underlying funds (the “optimization process”). The Advisor may make modifications to the optimization process from time to time to take certain qualitative factors into consideration. The Advisor runs the optimization process on a regular basis in order to integrate current market data and reallocate, as necessary, each Fund’s asset allocations.

The Asset Allocation Funds seek to integrate many of the central tenets of EPT, which include:

The Asset Allocation Funds offer three choices for different investment styles in accordance with different target risks. The following table indicates each Fund’s typical target allocation and risk, which is how each Fund’s investments will be generally allocated among the major asset classes over the long term. It is possible that each Fund’s target allocation may differ from these ranges, depending on market conditions or other factors.

In general, the All-Asset Conservative Strategy Fund may be appropriate for investors who have low risk tolerance and primarily seek preservation of capital from their investment. The All-Asset Moderate Strategy Fund may be appropriate for investors who have moderate risk tolerance, primarily seek growth from their investment, and are willing to bear some short-term price fluctuations in exchange for potentially higher returns over time. The All-Asset Aggressive Strategy Fund may be appropriate for investors who have an aggressive risk tolerance, primarily seek growth from their investment, and seek to maximize long-term returns with the ability to accept possible significant short or long-term losses.

Most underlying funds have risks associated with them as described either in this Prospectus or each underlying fund’s individual prospectus. You also may request an underlying fund’s prospectus or Statement of Additional Information by calling Guggenheim Investments Client Services at 800.820.0888 or 301.296.5100, or visiting the U.S. Securities and Exchange Commission’s (the “SEC”) website at www.sec.gov.

IMPORTANT INFORMATION REGARDING FUNDS THAT SEEK LEVERAGED AND INVERSE INVESTMENT RESULTS

The Mid-Cap 1.5x Strategy Fund, Russell 2000^® 1.5x Strategy Fund, Nova Fund, Emerging Markets 2x Strategy Fund, Strengthening Dollar 2x Strategy Fund, and Government Long Bond 1.2x Strategy Fund (the “Daily Leveraged Funds”) seek daily leveraged investment results. The Europe 1.25x Strategy Fund and Japan 2x Strategy Fund also seek leveraged investment results (the “Leveraged Funds”). The Inverse Emerging Markets 2x Strategy Fund and Weakening Dollar 2x Strategy Fund (the “Leveraged Inverse Funds”) seek to provide leveraged investment results that match or correlate to the opposite of the performance of a specific benchmark on a daily basis. The Inverse NASDAQ-100^® Strategy Fund, Inverse S&P 500 Strategy Fund, Inverse Mid-Cap Strategy Fund, Inverse Russell 2000^® Strategy Fund, and Inverse Government Long Bond Strategy Fund (the “Daily Inverse Funds”) seek to provide investment results that match or correlate to the opposite of the performance of a specific benchmark on a daily basis. The Inverse High Yield Strategy Fund seeks to provide investment results that inversely correlate to the performance of the

high yield bond market (the “Inverse Fund”). The Daily Leveraged Funds, Leveraged Funds, Leveraged Inverse Funds, Daily Inverse Funds and the Inverse Fund may be referred to collectively as the “Funds.”

As discussed in each Fund’s Summary section, the Funds’ performance is subject to the effects of compounding and leverage, which are discussed in more detail below.

It is important to understand the effects of compounding when investing in any mutual fund, especially funds that use leverage as part of their investment strategy. The effect of leverage on a fund will generally cause the fund’s performance to not match or correlate to the performance of the index underlying the fund’s benchmark over a period of time greater than one day. As a result, the use of leverage could cause the performance of a fund to be less than or greater than the performance of the index underlying the fund’s benchmark multiplied by the amount of leverage employed, before accounting for fees and expenses. The following simple examples provide an illustration:

Example A: Assume you invest $100 in Fund A, a typical index fund that seeks to match the performance of its underlying index. If the index increases 10% on day one, the value of your shares in Fund A would be expected to increase $10 (10% of $100) to $110. The next day, if the index decreases 10%, the value of your shares in Fund A would be expected to decrease $11 (10% of $110) to $99.

Example B: Assume you invested $100 in Fund B, a fund that seeks to return 200% of the performance of its underlying index. If the index increases 10% on day one, the value of your shares in Fund B would be expected to increase $20 (20% of $100) to $120. The next day, if the index decreases 10%, the value of your shares in Fund B would be expected to decrease $24 (20% of $120) to $96.

Because of the effect of compounding, in each case the value of your investment declined even though the index went up 10% on day one and down 10% on day two. However, the effect of compounding was more pronounced when combined with leverage (Example B).

The examples demonstrate that over time, the cumulative percentage increase or decrease in the NAV of a fund may diverge significantly from the cumulative percentage increase or decrease in the multiple of the return of the index underlying a fund’s benchmark due to the compounding effect of losses and gains on the returns of the fund. It also is expected that a fund’s use of consistently applied leverage will cause the fund to underperform the compounded return of twice its benchmark in a trendless or flat market.

The following graphs further illustrate the effect of leverage on fund performance in comparison to the performance of the fund’s underlying index in three different markets. Each of the three graphs shows a simulated hypothetical of the one-year performance of an index compared with the performance of a fund that perfectly achieves its investment objective of exactly twice (200%) the daily index returns.

In order to isolate the effect of leverage, the hypothetical graphs assume: (i) no tracking error (see “Tracking Error Risk” under “Descriptions of Principal Risks”); (ii) no dividends paid by the companies included in the underlying index; (iii) no expenses; and (iv) borrowing and/or lending rates (required to obtain leverage) of zero percent. If tracking error, fund expenses, and borrowing and lending rates of greater than zero percent were included in the graphs, the fund’s performance would be lower than that shown below. Each of the graphs also assumes an index volatility of 20%. An index’s volatility is a statistical measure of the magnitude of the fluctuations in the returns of an index. For example, the average of the most recent five-year historical volatility for the period ending June 30, 2012 of the S&P 500^® Index is 19.12%. The S&P 500^® Index’s volatility may be more or less significant at any given time. The indices underlying the Funds’ benchmarks have different historical volatilities, which may be more or less significant than the index volatilities assumed in the graphs below. The average historical volatility for the five-year period ended June 30, 2012 of the other indices underlying the Funds’ benchmarks is as follows: NASDAQ-100 Index^® 22.52%; Russell 2000^® Index 24.81%; S&P MidCap 400^® Index 22.89%; STOXX 50^® Index 24.93%; Nikkei 225 Stock Average 20.02%; BNY Mellon Emerging Markets 50 ADR Index 29.32%; and U.S. Dollar Index 10.55%. The hypothetical graphs are meant to demonstrate the effects of leverage only and are in no way indicative of the actual performance of any of the Funds.

MARKET VOLATILITY. Each Daily Leveraged Fund and Leveraged Inverse Fund seeks to provide a return that is a multiple of the daily performance of its benchmark. No Daily Leveraged Fund or Leveraged Inverse Fund attempts to, and no Daily Leveraged Fund or Leveraged Inverse Fund should be expected to, provide returns that are a multiple of the return of the benchmark for periods other than a single day. Each Daily Leveraged Fund and Leveraged Inverse Fund rebalances its portfolio on a daily basis, increasing exposure in response to that day’s gains or reducing exposure in response to that day’s losses.

Daily rebalancing will impair a Daily Leveraged Fund’s or Leveraged Inverse Fund’s performance if the benchmark experiences volatility. For instance, a hypothetical 2x daily leveraged fund would be expected to lose -3.9% (as shown in Table 1 below) if its benchmark provided no return over a one year period during which its benchmark experienced annualized volatility of 20%. If the benchmark’s annualized volatility were to rise to 40%, the hypothetical loss for a one year period for a 2x daily leveraged fund widens to approximately -14.8% while the loss for a 2x inverse fund rises to 38.0%. At higher ranges of volatility, there is a chance of a near complete loss of fund value even if the benchmark is flat. For instance, if annualized volatility of the benchmark is 90%, a 2x leveraged inverse fund targeted to the same benchmark would be expected to lose more than 90% of its value even if the cumulative benchmark return for the year was 0%. An index’s volatility rate is a statistical measure of the magnitude of fluctuations in the returns of an index.

Table 1 shows the hypothetical loss for a one-year period, assuming the above annualized volatility range for a hypothetical benchmark that provided no return over the one-year period. The hypothetical loss was determined based upon 100,000 simulations performed with randomly generated daily returns normally distributed around 0%. The return values shown represent the mean leveraged final return for all samples with an unleveraged final return between -1% and +1%.

Table 2 shows the range of volatility for the indices to which the Daily Leveraged Funds and Leveraged Inverse Funds are benchmarked for the five year period ended June 30, 2012. (In historical terms, volatility ranges during this period were extremely high). The indices to which the Funds are benchmarked have historical volatility rates over that period ranging from 9.68% to 27.19%. Since market volatility, like that experienced by the markets recently, has negative implications for funds that rebalance daily, investors should be sure to monitor and manage their investments in the Daily Leveraged Funds and Leveraged Inverse Funds in volatile markets. The negative implications of volatility in Table 1 can be combined with the recent volatility ranges of various indices in Table 2 to give investors some sense of the risks of holding the Daily Leveraged Funds and Leveraged Inverse Funds for long periods. These tables are intended to simply underscore the fact that the Daily Leveraged Funds and Leveraged Inverse Funds are designed for investors who (a) understand the risks associated with the use of leverage, (b) understand the consequences of seeking daily leveraged investment results, (c) understand the risk of shorting and (d) intend to actively monitor and manage their investments. They are not intended to be used by, and are not appropriate for, investors who do not intend to actively monitor and manage their portfolios.

A PRECAUTIONARY NOTE TO INVESTORS REGARDING DRAMATIC INDEX MOVEMENT. Each Daily Leveraged Fund seeks daily exposure to its target index equal to or in excess of 120% of its net assets while each Leveraged Inverse Fund seeks daily exposure to its target index equal to -200% of its net assets. As a consequence, for each Daily Leveraged Fund the risk of total loss of your investment exists in the event of a movement of the Daily Leveraged Fund’s target index in excess of 50% in a direction adverse to the Daily Leveraged Fund (meaning a decline in the value of the target index of a Daily Leveraged Fund) and for each Leveraged Inverse Fund the risk of total loss exists in the event of a movement of the Leveraged Inverse Fund’s target index in excess of 50% in a direction adverse to the Leveraged Inverse Fund (meaning a gain in the value of the target index of a Leveraged Inverse Fund). In short, the risk of total loss of your investment exists.

THE PROJECTED RETURNS OF LEVERAGED FUNDS FOR SHARES HELD LONGER THAN A FULL TRADING DAY. The Daily Leveraged Funds and Leveraged Inverse Funds seek daily leveraged investment results, which should not be equated with seeking a leveraged goal for longer than a day. For instance, if a Daily Leveraged Fund’s underlying index gains 10% for a week, the Daily Leveraged Fund’s shares should not be expected to provide a return of 20% for the week even if it meets its daily target throughout the week. This is true because of the fund expenses set forth in the prospectus, but also because the pursuit of daily goals may result in daily leveraged compounding, which means that the return of an index over a period of time greater than one day multiplied by a Daily Leveraged Fund’s or Leveraged Inverse Fund’s daily target or inverse daily target (e.g., 200% or -200%) will not generally equal a Daily Leveraged Fund’s or Leveraged Inverse Fund’s performance over that same period.

The following charts set out a range of hypothetical daily performances during a given 10 trading days of an index and demonstrate how changes in the index affect a Daily Leveraged Fund’s and Leveraged Inverse Fund’s performance for a trading day and cumulatively up to, and including, the entire 10 trading day period. The charts are based on a hypothetical $100 investment in a Daily Leveraged Fund and Leveraged Inverse Fund over a 10 trading day period and do not reflect expenses of any kind.

The cumulative performance of the index in Table 1 is 0% for 10 trading days. The hypothetical return of the Daily Leveraged Fund for the 10 trading day period is -6.11%, while the hypothetical return of the Leveraged Inverse Fund is -19.45%. The volatility of the benchmark performance and lack of clear trend results in performance for each Daily Leveraged Fund and Leveraged Inverse Fund for the period which bears little relationship to the performance of the Funds’ target index for the 10 trading day period.

The cumulative performance of the index in Table 2 is 20% for 10 trading days. The hypothetical return of the Daily Leveraged Fund for the 10 trading day period is 43.53%, while the hypothetical return of the Leveraged Inverse Fund is -31.27%. The hypothetical return of the Daily Leveraged Fund is 218% of the index return for the 10 trading day period while the hypothetical return of the Leveraged Inverse Fund is -156% of the index return for the period. In this case, because of the positive index trend, the Daily Leveraged Fund gain is greater than 200% of the index gain and the Leveraged Inverse Fund decline is less than -200% of the index gain for the 10 trading day period.

The cumulative performance of the index in Table 3 is -20% for 10 trading days. The hypothetical return of the Daily Leveraged Fund for the 10 trading day period is -36.33%, while the hypothetical return of the Leveraged Inverse Fund is 54.01%. The hypothetical return of the Daily Leveraged Fund is 182% of the index return for the 10 trading day period, while the hypothetical return of the Leveraged Inverse Fund is -270% of the index return for the period. In this case, because of the negative index trend, the Daily Leveraged Fund decline is less than 200% of the index decline and the Leveraged Inverse Fund gain is greater than 200% of the index decline for the 10 trading day period.

The following section provides additional information regarding the principal risks summarized under “Principal Risks” in the Fund Summaries. The risks below may not be applicable to each Fund. Please consult the Fund Summary sections to determine which risks are applicable to a particular Fund.

Active Trading Risk – A significant portion of the Fund’s assets may come from investors who take part in certain strategic and tactical asset allocation programs. These programs often recommend frequent trading of Fund shares to take advantage of anticipated changes in market conditions. Therefore, the Advisor anticipates that investors who take part in these programs may frequently redeem or exchange shares of the Fund, which may cause the Fund to experience high portfolio turnover. High portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. In addition, large movements of assets into and out of the Fund may negatively impact the Fund’s ability to achieve its investment objective. In certain circumstances, the Fund’s expense ratio may vary from current estimates or the historical ratio disclosed in this Prospectus.

Capitalization Securities Risk – For each Domestic Equity Fund, Sector Fund, International Equity Fund, and the Real Estate Fund, U.S. Long Short Momentum Fund, Event Driven and Distressed Strategies Fund, and Long Short Equity Strategy Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, the Fund’s or underlying funds’ investments may be composed primarily of, or have significant exposure to, securities in a particular capitalization range, e.g., large, mid or small-cap securities. As a result, the Fund may be subject to the risk that the predominate capitalization range represented in the Fund’s portfolio, and in the case of the Asset Allocation Funds, in an underlying fund’s portfolio, may underperform other segments of the equity market or the equity market as a whole. If the Fund has net short exposure to the components of its underlying index or other benchmark it is subject to the risk that the predominate capitalization range represented in its underlying index or benchmark may outperform other segments of the equity market or the equity market as a whole. In addition, in comparison to securities of companies with larger capitalizations, securities of small and medium-capitalization companies may experience more price volatility, greater spreads between their bid and ask prices, significantly lower trading volumes, and cyclical or static growth prospects. Small and medium-capitalization companies often have limited product lines, markets or financial resources, and may therefore be more vulnerable to adverse developments than larger capitalization companies. These securities may or may not pay dividends.

Commodity-Linked Derivative Investment Risk – In the case of the Asset Allocation Funds, certain of the underlying funds’ exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. Because the value

of a commodity-linked derivative investment typically is based upon the price movements of a physical commodity (such as heating oil, livestock, or agricultural products), a commodity futures contract or commodity index, or some other readily measurable economic variable, the value of commodity-linked derivative instruments may be affected by changes in overall market movements, volatility of the underlying index or benchmark, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and regulatory developments.

An underlying fund’s investments in commodity-linked derivatives are subject to a substantial risk of loss. When an underlying fund purchases or sells a commodity futures contract, sells a commodity option or engages in off-exchange foreign currency trading, it may sustain a total loss of the initial margin or other monies posted by the underlying fund to establish or maintain its position. If the market moves against the underlying fund’s position, it may be required to post additional monies to maintain its position, which also are subject to total loss. If the underlying fund chooses not to post additional monies to maintain a position, it may be forced to liquidate the position at a loss. Certain of the underlying funds’ investment in commodity-related investment products may lead to substantial losses, which can significantly and adversely affect the net asset value (“NAV”) of the Fund and, consequently, a shareholder’s interest in the Fund.

Index-Linked and Commodity-Linked “Structured” Securities – In the case of the Asset Allocation Funds, certain of the underlying funds invest in derivative instruments with principal and/or coupon payments linked to the value of commodities, commodity futures and options contracts, or the performance of commodity indices, such as the Standard & Poor’s Diversified Trends Indicator^® or S&P GSCI^TM Commodity Index. These are “commodity-linked” or “index-linked” securities. They are sometimes referred to as “structured securities” because the terms of the instrument may be structured by the issuer of the security and the purchaser of the security, such as an underlying fund. These securities may be issued by banks, brokerage firms, insurance companies and other corporations.

The value of these securities will rise or fall in response to changes in the underlying commodity or related index or investment. These securities expose the Fund economically to movements in commodity prices. In addition to commodity price risk, the securities also are subject to credit and interest rate risks that in general affect the values of debt securities. Therefore, at maturity, an underlying fund may receive more or less principal than it originally invested. An underlying fund might receive interest payments that are more or less than the stated coupon interest payments.

Structured Note Risk – In the case of the Asset Allocation Funds, certain of the underlying funds intend to invest in commodity, currency and financial-linked structured notes to a significant extent. Commodity-linked structured notes provide exposure, which may include long and/or short exposure, to the investment returns of “real assets” (i.e., assets that have tangible properties such as oil, gold and silver) that trade in the commodities markets without investing directly in physical commodities. The performance of these notes is determined by the price movement of the commodities underlying the note. Currency and financial-linked structured notes provide exposure to the investment returns of currencies and financial instruments. The fees associated with a structured note, which are embedded in the price of the structured note paid by an underlying fund may lead to increased tracking error. In addition, a highly liquid secondary market may not exist for the structured notes. However, the Advisor believes that other mutual funds will continue to increase their investment in commodity-linked structured notes leading to the creation and maintenance of a more liquid secondary market.

Conflicts of Interest Risk – In managing the Fund, the Advisor will have the authority to select and substitute underlying funds. The Advisor is subject to conflicts of interest in doing so and in allocating Fund assets among the various underlying funds, both because the fees payable to it by some underlying funds may be higher than the fees payable by other underlying funds and because the Advisor also is responsible for managing each of the affiliated underlying funds. The Advisor is legally obligated to disregard the fees payable by underlying funds when making investment decisions. The Trustees and officers of the Fund are also Trustees and officers of the affiliated underlying funds and thus may have conflicting interests in fulfilling their fiduciary duties to both the Fund and the affiliated underlying funds.

Correlation and Compounding Risk – A number of factors may affect the Fund’s ability to achieve a high degree of correlation with its benchmark, and there can be no guarantee that the Fund will achieve a high degree of correlation. Failure to achieve a high degree of correlation may prevent the Fund from achieving its investment objective. A number of factors may adversely affect the Fund’s correlation with its benchmark, including fees, expenses, transaction costs, costs and risks associated with the use of leveraged investment techniques, income items, accounting standards and disruptions or illiquidity in the markets for the securities or financial instruments in which the Fund invests. The Fund may not have investment exposure to all securities in its underlying index or benchmark, or its weighting of investment exposure to such securities or industries may be different from that of its underlying index or benchmark. In addition, the Fund may invest in securities or financial instruments not included in its underlying index or benchmark. The Fund may be subject to large movements of assets into and out of the Fund, potentially resulting in the

Fund being over- or under-exposed to its benchmark. If the Fund seeks to meet its investment objective on a daily basis, activities surrounding annual index reconstitutions and other index rebalancing or reconstitution events may hinder the Fund’s ability to meet its daily investment objective on that day.

Each of the Nova Fund, Mid-Cap 1.5x Strategy Fund, Russell 2000^® 1.5x Strategy Fund, Strengthening Dollar 2x Strategy Fund, Weakening Dollar 2x Strategy Fund, and Government Long Bond 1.2x Strategy Fund is considered a “leveraged” fund because it seeks to match or correlate to a multiple or a multiple of the inverse of the performance of the Fund’s underlying index or benchmark on a daily basis. The Europe 1.25x Strategy Fund and Japan 2x Strategy Fund are also “leveraged” funds but have investment objectives to correlate to a multiple of the performance of each Fund’s underlying index over time. The Funds listed above are subject to all of the correlation risks described above. In addition, there is a special form of correlation risk that derives from the Nova Fund’s, Mid-Cap 1.5x Strategy Fund’s, Russell 2000^® 1.5x Strategy Fund’s, Strengthening Dollar 2x Strategy Fund’s, Weakening Dollar 2x Strategy Fund’s, and Government Long Bond 1.2x Strategy Fund’s having a single day investment objective in combination with the use of leverage, which is that for periods greater than one day, the effect of compounding may cause the performance of the Fund to be either greater than or less than the performance of the Fund’s underlying index or benchmark (or the inverse of the performance of the Fund’s underlying index or benchmark) times the stated multiple in the Fund objective, before accounting for fees and fund expenses.

Counterparty Credit Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, may invest in financial instruments involving counterparties for the purpose of attempting to gain exposure to a particular group of securities, index or asset class without actually purchasing those securities or investments, or to hedge a position. Such financial instruments may include, among others, total return, index, interest rate, credit default swap agreements, and structured notes. The Fund and certain of the underlying funds will use short-term counterparty agreements to exchange the returns (or differentials in rates of return) earned or realized in particular predetermined investments or instruments. The Fund and affiliated underlying funds will not enter into any agreement with a counterparty unless the Advisor believes that the other party to the transaction is creditworthy. The use of swap agreements, structured notes and similar instruments involves risks that are different from those associated with ordinary portfolio securities transactions. For example, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. If a counterparty defaults on its payment obligations to the Fund or an underlying fund, this default will cause the value of your investment in the Fund to decrease. In addition, the Fund and certain of the underlying funds may enter into swap agreements with a limited number of counterparties, which may increase the Fund’s exposure to counterparty credit risk. The Advisor considers factors such as counterparty credit ratings and financial statements among others when determining whether a counterparty is creditworthy. The Advisor regularly monitors the creditworthiness of each counterparty that the Fund enters into a transaction with. Swap agreements and structured notes also may be considered to be illiquid. Similarly, if the credit quality of an issuer or guarantor of a debt instrument improves, this change may adversely affect the value of the Fund’s investment.

To the extent the Fund’s or an underlying fund’s financial instrument counterparties are concentrated in the financial services sector, the Fund bears the risk that those counterparties may be adversely affected by legislative or regulatory changes, adverse market conditions, increased competition, and/or wide scale credit losses resulting from financial difficulties or borrowers affecting that economic sector.

Credit Default Swap Risk – The Event Driven and Distressed Strategies Fund, Long Short Equity Strategy Fund, High Yield Strategy Fund, Inverse High Yield Strategy Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, may each enter into credit default swap agreements. A credit default swap agreement is an agreement between two parties: a buyer of credit protection and a seller of credit protection. The Fund may be either the buyer of credit protection against a designated event of default, restructuring or other credit related event (each a “Credit Event”) or the seller of credit protection in a credit default swap. The buyer in a credit default swap agreement is obligated to pay the seller a periodic stream of payments over the term of the swap agreement. If no Credit Event occurs, the seller of credit protection will have received a fixed rate of income throughout the term of the swap agreement. If a Credit Event occurs, the seller of credit protection must pay the buyer of credit protection the full notional value of the reference obligation either through physical settlement or cash settlement. If no Credit Event occurs, the buyer of credit protection will have made a series of periodic payments through the term of the swap agreement. However, if a Credit Event occurs, the buyer of credit protection will receive the full notional value of the reference obligation either through physical settlement or cash settlement from the seller of credit protection. A credit default swap may involve greater risks than if the Fund invested directly in the underlying reference obligations. For example, a credit default swap may increase the Fund’s or an underlying fund’s credit risk because it has exposure to both the issuer of the underlying reference obligation and the counterparty to the credit default swap. In addition, credit default swap agreements may be difficult to value depending on whether an active market exists for the credit default swaps in which the Fund invests.

Credit Risk – For the Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, credit risk is the risk that the Fund could lose money if the issuer or guarantor of a debt instrument in which the Fund or underlying fund invests becomes unwilling or unable to make timely principal and/or interest payments, or to otherwise meet its obligations. For the Inverse High Yield Strategy Fund, credit risk is the risk that the Fund could lose money if the credit quality, or the perception of the financial condition, of the issuer or guarantor of a debt instrument is either upgraded or improves. Securities are subject to varying degrees of credit risk, which are sometimes reflected in credit ratings.

Credit and Equity-Linked Derivative Investment Risk – Because the value of a credit or equity-linked derivative investment typically is based upon the price movements of the credit instrument, equity security or credit or equity index, or some other readily measurable economic variable, the value of credit or equity-linked derivative instruments may be affected by changes in overall market movements, volatility of the benchmark, changes in interest rates, or factors affecting a particular industry or security, such as international economic, political and regulatory developments or significant changes in the credit-worthiness of an issuer.

Structured Note Risk – The Fund intends to invest in credit and equity-linked structured notes to a significant extent. The performance of these notes is determined by the price movement of the investment, security or index underlying the note. The fees associated with a structured note, which are embedded in the price of the structured note paid by the Fund, may lead to increased tracking error. In addition, a highly liquid secondary market may not exist for the structured notes, and there can be no assurance that one will develop.

Currency Risk – The Fund’s, and in the case of the Asset Allocation Funds, certain of the underlying funds’, indirect and direct exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. dollar, or, in the case of short positions, that the U.S. dollar will decline in value relative to the currency being hedged. Similarly, the Strengthening Dollar 2x Strategy Fund’s exposure to the U.S. Dollar Index^® subjects the Fund to the risk that foreign currencies will appreciate in value relative to the U.S. dollar. Conversely, the Weakening Dollar 2x Strategy Fund’s exposure to the U.S. Dollar Index^® subjects the Fund to the risk that foreign currencies will depreciate in value relative to the U.S. dollar. To the extent the U.S. Dollar Index^® is heavily weighted in a particular currency, the Strengthening Dollar 2x Strategy Fund and Weakening Dollar 2x Strategy Fund will necessarily have concentrated exposures to that same currency. Currently, the Euro is the most heavily weighted of the six foreign currencies represented by the U.S. Dollar Index^® at approximately 58%. Currency rates in foreign countries may fluctuate significantly over short periods of time for a number of reasons, including changes in sovereign debt levels and trade deficits; domestic and foreign inflation and interest rates and investors’ expectations concerning those rates; currency exchange rates; investment and trading activities of other funds, including hedge funds and currency funds; and global or regional political, economic or financial events and situations and the imposition of currency controls or other political developments in the U.S. or abroad. The Fund and certain of the underlying funds may, but are not obligated to, engage in currency hedging transactions, which generally involve buying currency forward, options or futures contracts. However, not all currency risk may be effectively hedged, and in some cases the costs of hedging techniques may outweigh expected benefits. In such instances, the value of securities denominated in foreign currencies can change significantly when foreign currencies strengthen or weaken relative to the U.S. dollar.

The Europe 1.25x Strategy Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, may have indirect and direct exposure to the euro, which has experienced increased volatility in recent months. The increased volatility in the price of euro, which has fluctuated widely over the past several years, is due, in part, to concern over the sovereign debt levels of certain European Union (EU) members and the potential effect of this debt on EU members’ participation in the European Monetary Union and the value of the euro. If such volatility persists, the euro may not maintain its current purchasing power in the future. A decline in the price of the euro may adversely affect the Fund’s performance.

Depositary Receipt Risk – The Fund may hold the securities of non-U.S. companies in the form of ADRs. ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the NYSE. The Fund or an underlying fund will primarily invest in sponsored ADRs, which are issued with the support of the issuer of the foreign stock underlying the ADRs and which carry all of the rights of common shares, including voting rights. The underlying securities of the ADRs in the Fund’s or an underlying fund’s portfolio are usually denominated or quoted in currencies other than the U.S. dollar. As a result, changes in foreign currency exchange rates may affect the value of the Fund’s portfolio. Generally, when the U.S. dollar rises in value against a foreign currency, a security denominated in that currency loses value because the currency is worth fewer U.S. dollars. In addition, because the underlying securities of ADRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for shares of the Fund or underlying fund. Investments in the underlying foreign securities may involve risks not typically associated with investing in U.S. companies. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets can be extremely volatile due to increased risks of adverse issuer, political, regulatory, market,

or economic developments. Many foreign countries lack accounting and disclosure standards comparable to those that apply to U.S. companies, and it may be more difficult to obtain reliable information regarding a foreign issuer’s financial condition and operations. In addition, transaction costs and costs associated with custody services are generally higher for foreign securities than they are for U.S. securities.

Derivatives Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, may invest a percentage of their assets in derivatives, such as futures and options contracts, to pursue their investment objectives. The use of such derivatives may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. The Fund, or in the case of the Asset Allocation Funds, certain of the underlying funds, may use futures contracts and related options for bona fide hedging purposes to offset changes in the value of securities held or expected to be acquired. They also may be used to gain exposure to a particular market or instrument, to create a synthetic money market position, and for certain other tax-related purposes. The Fund and affiliated underlying funds will only enter into futures contracts traded on a CFTC-approved futures exchange or board of trade. Futures and options contracts are described in more detail below:

Futures Contracts – Futures contracts and options on futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific security at a specified future time and at a specified price. An option on a futures contract gives the purchaser the right, in exchange for a premium, to assume a position in a futures contract at a specified exercise price during the term of the option. Index futures are futures contracts for various indices that are traded on registered securities exchanges.

Options – The buyer of an option acquires the right to buy (a call option) or sell (a put option) a certain quantity of a security (the underlying security) or instrument at a certain price up to a specified point in time. The seller or writer of the option is obligated to sell (a call option) or buy (a put option) the underlying security. When writing (selling) call options on securities, the Fund or an underlying fund may cover its positions by owning the underlying security on which the option is written or by owning a call option on the underlying security. Alternatively, the Fund or an underlying fund may cover its positions by maintaining, in a segregated account, cash or liquid securities equal in value to the exercise price of the call options written by the Fund or an underlying fund.

The risks associated with the Fund’s or an underlying fund’s use of futures and options contracts include:

Early Closing Risk – The normal close of trading of securities listed on NASDAQ and the NYSE is 4:00 p.m., Eastern Time. Unanticipated early closings of securities exchanges and other financial markets may result in the Fund’s inability to buy or sell securities or other financial instruments on that day. If an exchange or market closes early on a day when the Fund needs to execute a high volume of trades late in a trading day, the Fund might incur substantial trading losses.

Emerging Markets Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, may invest in emerging markets. Emerging markets, which consist of countries that have an emerging stock market as defined by Standard & Poor’s^®, countries or markets with low- to middle-income economies as classified by the World Bank, and other countries or markets with similar characteristics as determined by the Advisor, can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market, or economic developments and can perform differently from the U.S. market. Emerging markets can be subject to greater social, economic, regulatory, and political uncertainties and can be extremely volatile. As a result, the securities of emerging market issuers may present market, credit, currency, liquidity, legal, political and other risks different from, or greater than, the risks of investing in securities of developed foreign countries. In addition, the risks associated with investing in a narrowly defined geographic area are generally more pronounced with respect to investments in emerging

market countries. The Asset Allocation Funds also may be subject to this risk with respect to certain of the underlying funds’ investments in derivatives or other securities or financial instruments whose returns are related to the returns of emerging market securities.

Exchange-Traded Notes (ETNs) Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds may invest in ETNs. ETNs are a type of unsecured, unsubordinated debt security that have characteristics and risks similar to those of fixed-income securities and trade on a major exchange similar to shares of ETFs. However, this type of debt security differs from other types of bonds and notes because ETN returns are based upon the performance of a market index minus applicable fees, no period coupon payments are distributed, and no principal protections exist. The purpose of ETNs is to create a type of security that combines the aspects of both bonds and ETFs. The value of an ETN may be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying commodities or securities markets, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced commodity or security. The Fund’s or an underlying fund’s decision to sell its ETN holdings also may be limited by the availability of a secondary market. If the Fund or underlying fund must sell some or all of its ETN holdings and the secondary market is weak, it may have to sell such holdings at a discount. If the Fund or underlying fund holds its investment in an ETN until maturity, the issuer will give the Fund or underlying fund a cash amount that would be equal to principal amount (subject to the day’s index factor). ETNs are also subject to counterparty credit risk and fixed income risk.

Fixed Income Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds may invest in fixed income securities or related instruments. The market value of fixed income investments, and financial instruments related to those fixed income investments, will change in response to interest rate changes and other factors, such as changes in the effective maturities and credit ratings of fixed income investments. During periods of falling interest rates, the values of outstanding fixed income securities generally rise. While such periods may benefit the High Yield Strategy Fund, they may cause the value of an investment in the Inverse High Yield Strategy Fund to decrease. In addition, falling interest rates may cause an issuer to redeem or “call” a security before its stated maturity, which may result in the Government Long Bond 1.2x Strategy Fund or Inverse Government Long Bond Strategy Fund having to reinvest the proceeds in lower or higher coupon securities, respectively. Conversely, during periods of rising interest rates, the values of such securities and related financial instruments generally decline. The value of an investment in the High Yield Strategy Fund may decline during periods of rising interest rates. While securities with longer maturities tend to produce higher yields, the prices of longer maturity securities are also subject to greater market fluctuations as a result of changes in interest rates. With respect to the High Yield Strategy Fund and Inverse High Yield Strategy Fund, the prices of high yield bonds, unlike those of investment grade bonds, may fluctuate unpredictably and not necessarily inversely with changes in interest rates. Fixed income investments are also subject to credit risk, which is the possibility that the credit strength of an issuer will weaken and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default.

Foreign Issuer Exposure Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds may invest in securities of foreign companies directly, or in financial instruments, such as ADRs, ETFs, and structured notes, that are indirectly linked to the performance of foreign issuers. The High Yield Strategy and Inverse High Yield Strategy Funds may invest in instruments that are linked to the performance of foreign issuers, primarily Canadian issuers. Foreign markets can be more volatile than the U.S. market due to increased risks of adverse issuer, political, regulatory, market or economic developments and can perform differently from the U.S. market. Investing in securities of foreign companies directly, or in financial instruments that are indirectly linked to the performance of foreign issuers, may involve risks not typically associated with investing in U.S. issuers. The value of financial instruments denominated in foreign currencies, and of distributions from such financial instruments, can change significantly when foreign currencies strengthen or weaken relative to the U.S. dollar. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets, and prices in some foreign markets may fluctuate more than those of financial instruments traded on U.S. markets. Many foreign countries lack accounting and disclosure standards comparable to those that apply to U.S. companies, and it may be more difficult to obtain reliable information regarding a foreign issuer’s financial condition and operations. Transaction costs and costs associated with custody services are generally higher for foreign securities than they are for U.S. securities. Some foreign governments levy withholding taxes against dividend and interest income. Although in some countries portions of these taxes are recoverable, the non-recovered portion will reduce the income received by the Fund. With respect to the High Yield Strategy and Inverse High Yield Strategy Funds, the Canadian economy can be significantly affected by the U.S. economy and the price of natural resources. In addition, periodic demands by the Province of Quebec for sovereignty could significantly affect the Canadian market.

Fund of Funds Risk – The Fund is subject to fund of funds risk. By investing in the underlying funds indirectly through the Fund, an investor will incur not only a proportionate share of the expenses of the underlying funds held by the Fund (including operating costs and management fees), but also expenses of the Fund. Consequently, an investment in the Fund entails more direct and

indirect expenses than a direct investment in the underlying funds. In order to minimize these expenses, the Fund intends to invest in the class of shares of each underlying fund with the lowest shareholder fees and net fund operating expenses.

In addition, an underlying fund may buy the same securities that another underlying fund sells. If this happens, an investor in the Fund would indirectly bear the costs of these trades without accomplishing any investment purpose. Also, the Fund investor may receive taxable gains from portfolio transactions by the underlying funds, as well as taxable gains from the Fund’s transactions in shares of the underlying funds. In addition, certain of the underlying funds may hold common portfolio positions, thereby reducing the diversification benefits of an asset allocation style. Because the Fund invests most of its assets in underlying funds, the Fund’s investment performance is directly related to the performance of those underlying funds. The performance of those underlying funds, in turn, depends upon the performance of the securities in which they invest.

Geographic Concentration in Europe Risk – Because a significant portion of the assets of the Fund are invested in a specific geographical region, the value of its investments and the NAV of the Fund could decline more dramatically as a result of adverse events affecting Europe. In addition, countries in Europe may be significantly affected by the tight fiscal and monetary controls of the European Economic and Monetary Union (EMU).

Geographic Concentration in Japan Risk – Targeting Japan could hurt the Fund’s performance if Japan’s economy performs poorly as a result of political and economic conditions that affect the Japanese market. Japanese economic growth has weakened after the sharp collapse of the stock market in the 1990s and the current economic condition remains uncertain. Japanese stocks tend to be more volatile than their U.S. counterparts, for reasons ranging from political and economic uncertainties to a higher risk that essential information may be incomplete or erroneous. The Fund may be more volatile than a geographically diversified equity fund.

Growth Stocks Risk – Growth stocks generally are priced higher than non-growth stocks, in relation to the issuer’s earnings and other measures, because investors believe they have greater growth potential. However, there is no guarantee that such an issuer will realize that growth potential. In addition, an investment in growth stocks also may be susceptible to rapid price swings, especially during periods of economic uncertainty or in response to adverse news about the condition of the issuer, such as earnings disappointments. Growth stocks also typically have little or no dividend income to absorb the effect of adverse market conditions.

High Yield Risk – The Fund, or in the case of the Asset Allocation Funds, certain of the underlying funds, may invest in high yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”). High yield securities generally pay higher yields (greater income) than investment in higher quality securities; however, high yield securities and junk bonds may be subject to greater levels of interest rate, credit and liquidity risk than funds that do not invest in such securities, and are considered predominantly speculative with respect to an issuer’s continuing ability to make principal and interest payments. The value of these securities often fluctuates in response to company, political or economic developments and declines significantly over short periods of time or during periods of general economic difficulty. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce the ability of the Fund or certain underlying funds to sell these securities (liquidity risk). These securities can also be thinly traded or have restrictions on resale, making them difficult to sell at an acceptable price. If the issuer of a security is in default with respect to interest or principal payments, the Fund or underlying fund may lose its entire investment. The High Yield Strategy Fund seeks to correspond generally to the total return of the high yield bond market and thus an investment in the Fund will generally decline in value when the high yield bond market is losing value. By contrast, the Inverse High Yield Strategy Fund seeks to correspond generally to the inverse (opposite) of the total return of the high yield bond market, and thus an investment in the Fund will generally decline in value when the high yield bond market is gaining value.

Income Risk – Income Risk involves the potential for decline in the Fund’s, and in the case of the Asset Allocation Funds, certain of the underlying funds’ yield (the rate of dividends the Fund or the underlying fund pays) in the event of declining interest rates. Because the Fund or underlying fund primarily invests in money market instruments and other short-term securities that are based on short-term interest rates, which can fluctuate significantly over short periods, the risk of decline in the Fund’s or underlying fund’s yield may be greater than funds that invest in longer term securities that lock in interest rates. For example, if the Fund or an underlying fund invests in money market securities with maturities of less than one year and interest rates decline, then the yield of the Fund or underlying fund will also decline because when the money market securities mature, the returns are reinvested at lower interest rates.

Industry Concentration Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds’ may concentrate their investments in a limited number of issuers conducting business in the same industry or group of related industries. Market conditions, interest rates, and economic, regulatory, or financial developments could significantly affect a single industry or a group of related industries, and the securities of companies in that industry or group of industries could react similarly to these or other developments.

Interest Rate Risk – The Fund may be subject to Interest Rate Risk. The market value of fixed income investments, and financial instruments related to those fixed income investments, will change in response to interest rate changes. During periods of falling interest rates, the values of fixed income securities generally rise. Conversely, during periods of rising interest rates, the values of such securities generally decline. While securities with longer maturities tend to produce higher yields, the prices of longer maturity securities are also subject to greater market fluctuations as a result of changes in interest rates. However, the extremely short maturity of securities held in the Fund – a means of achieving an overall investment objective of principal safety – reduces the likelihood of price fluctuation.

Investment in Investment Companies Risk – The Fund may purchase shares of investment companies, such as ETFs, mutual funds, unit investment trusts, and closed-end investment companies, which may trade at discount to their NAV, to gain exposure to a particular portion of the market while awaiting an opportunity to purchase securities directly or when such investments present a more cost efficient alternative to investing directly in securities. The Asset Allocation Funds, in particular, will regularly invest in other investment companies, including the underlying funds, some of which also may invest in investment companies, and ETFs. When the Fund invests in an investment company, including affiliated underlying funds, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the investment company’s expenses. For example, if an underlying fund sells the same securities another underlying fund is purchasing, an investor in an Asset Allocation Fund would indirectly bear the costs of these trades without accomplishing any investment purpose. Similarly, an investor in an Asset Allocation Fund may receive taxable gains as a result of the underlying funds’ portfolio transactions in addition to the taxable gains attributable to an Asset Allocation Fund’s transactions in shares of the underlying funds. Further, in part because of these additional expenses, the performance of an investment company may differ from the performance the Fund would achieve if it invested directly in the underlying investments of the investment company. In addition, while the risks of owning shares of an investment company generally reflect the risks of owning the underlying investments of the investment company, the Fund may be subject to additional or different risks than if the Fund had invested directly in the underlying investments. For example, shares of an ETF are traded at market prices, which may vary from the NAV of its underlying investments. Also, the lack of liquidity in an ETF can contribute to the increased volatility of its value in comparison to the value of the underlying portfolio securities. In addition, the Fund and certain of the underlying funds may invest in investment companies or other pooled investment vehicles that are not registered pursuant to the 1940 Act and therefore, not subject to the regulatory scheme of the 1940 Act.

Exchange-Traded Fund (ETF) Risk – The Emerging Markets 2x Strategy Fund, Inverse Emerging Markets 2x Strategy Fund, Event Driven and Distressed Strategies Fund, Long Short Equity Strategy Fund, Long Short Interest Rate Strategy Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, may invest in shares of ETFs to gain exposure to its investment objective. ETFs are pooled investment vehicles, which may be managed or unmanaged, that generally seek to track the performance of a specific index. Although individual shares of an ETF are traded on an exchange (such as the NYSE or NASDAQ), large blocks of shares of ETFs are redeemable at NAV. This ability to redeem large blocks of shares has historically resulted in the market price of individual shares of ETFs being at or near the NAV of the ETF’s underlying investments. However, shares of ETFs may trade below their NAV. The NAV of shares will fluctuate with changes in the market value of the ETF’s holdings. The trading prices of shares will fluctuate in accordance with changes in NAV as well as market supply and demand. The difference between the bid price and ask price, commonly referred to as the “spread,” will also vary for an ETF depending on the ETF’s trading volume and market liquidity. Generally, the greater the trading volume and market liquidity, the smaller the spread is and vice versa. Any of these factors may lead to an ETF’s shares trading at a premium or a discount to NAV. The Fund, from time to time, may invest in exchange-traded investment funds that are not registered pursuant to the 1940 Act. Such exchange-traded investment funds may include commodity pools that are registered pursuant to the Securities Act of 1933 and the Commodity Exchange Act.

Investment in the Subsidiary Risk – In the case of the Asset Allocation Funds, certain of the underlying funds may invest in wholly-owned and controlled Cayman Islands subsidiaries (each, a “Subsidiary” and together, the “Subsidiaries”). The Subsidiaries are not registered under the 1940 Act and, unless otherwise noted in this Prospectus, are not subject to all of the investor protections of the 1940 Act. Thus, each such underlying fund, as an investor in its respective Subsidiary, will not have all of the protections offered to investors in registered investment companies. However, each such underlying fund wholly owns and controls its respective Subsidiary, and the underlying funds and the Subsidiaries are both managed by the Advisor, making it unlikely that the Subsidiaries will take action contrary to the interests of the underlying funds or their shareholders. While the Subsidiaries have their own board of directors that is responsible for overseeing the operations of the Subsidiaries, the underlying funds’ Board has oversight responsibility for the investment activities of the underlying funds, including their investments in the Subsidiaries, and each underlying fund’s role as the sole shareholder of its respective Subsidiary. Also, to the extent they are applicable to the investment activities of the Subsidiaries, the Advisor will be subject to the same fundamental investment restrictions that apply to the management of the underlying funds in managing each Subsidiary’s portfolio. It is not currently expected that shares of the Subsidiaries will be sold or offered to investors other than the underlying funds.

Changes in the laws of the United States and/or the Cayman Islands, under which the underlying funds and the Subsidiaries, respectively, are organized, could result in the inability of the underling funds and/or the Subsidiaries to operate as intended and could negatively affect the underlying funds and their shareholders. For example, Cayman Islands law does not currently impose any income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiaries. If Cayman Islands law changes such that the Subsidiaries must pay a Cayman Islands governmental authority taxes, Fund shareholders would likely suffer decreased investment returns.

Investment Technique Risk – The Event Driven and Distressed Strategies Fund, Long Short Equity Strategy Fund, Long Short Interest Rate Strategy Fund, High Yield Strategy Fund, Inverse High Yield Strategy Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds may use investment techniques that may be considered aggressive. Risks associated with the use of derivatives, including futures contracts, options, structured notes, and swap agreements, include potentially dramatic price changes (losses) in the value of the instruments and imperfect correlations between the price of the contract and the underlying security or index. These instruments may increase the volatility of the Fund or underlying fund and may involve a small investment of cash relative to the magnitude of the risk assumed. These techniques also may expose the Fund or underlying fund to risks different from or possibly greater than the risks associated with investing directly in the securities underlying the Fund’s or underlying fund’s derivative investments, including: 1) the risk that an instrument is temporarily mispriced; 2) credit or performance risk on the amount the Fund or underlying fund expects to receive from a counterparty; 3) the risk that security prices, interest rates and currency markets will move adversely and the Fund or underlying fund will incur significant losses; 4) imperfect correlation between the price of financial instruments and movements in the prices of the underlying securities; and 5) the possible absence of a liquid secondary market for any particular instrument and possible exchange imposed price fluctuation limits, both of which may make it difficult or impossible to adjust the Fund’s or underlying fund’s position in a particular instrument when desired.

Issuer Specific Risk – The value of a security may increase or decrease for a number of reasons which directly relate to the issuer. For example, with respect to the High Yield Strategy Fund, perceived poor management performance, financial leverage or reduced demand of the issuer’s goods or services may contribute to a decrease in the value of a security. A decrease in the value of the securities of an issuer or guarantor of a debt instrument may cause the value of your investment in the High Yield Strategy Fund to decrease. Conversely, with respect to the Inverse High Yield Strategy Fund, effective management, improved financial condition or increased demand of the issuer’s goods or services are factors that may contribute to an increase in the value of a security. An increase in the value of the securities of an issuer or guarantor of a debt instrument may cause the value of your investment in the Inverse High Yield Strategy Fund to decrease.

Leveraging Risk – The U.S. Long Short Momentum Fund, Event Driven and Distressed Strategies Fund, Long Short Equity Strategy Fund and Long Short Interest Rate Strategy Fund may each invest in leveraged instruments in pursuit of its investment objective. The Nova Fund, Mid-Cap 1.5x Strategy Fund, Russell 2000^® 1.5x Strategy Fund, International Equity Funds, Strengthening Dollar 2x Strategy Fund, Weakening Dollar 2x Strategy Fund, Government Long Bond 1.2x Strategy Fund and certain of the Asset Allocation Funds’ underlying funds, achieve leveraged exposure to their respective underlying indices through the use of derivative instruments. The more the Fund and certain of the underlying funds invest in derivative instruments that give rise to leverage, the more this leverage will magnify any losses on those investments. Leverage will cause the value of the Fund’s shares to be more volatile than if the Fund did not use leverage. This is because leverage tends to exaggerate the effect of any increase or decrease in the value of the Fund’s portfolio securities or other investments. The Fund and certain of the underlying funds will engage in transactions and purchase instruments that give rise to forms of leverage. Such transactions and instruments may include, among others, the use of reverse repurchase agreements and other borrowings, the investment of collateral from loans of portfolio securities, the use of when issued, delayed-delivery or forward commitment transactions or short sales. The use of leverage also may cause the Fund or an underlying fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet segregation requirements. Certain types of leveraging transactions, such as short sales that are not “against the box,” could theoretically be subject to unlimited losses in cases where the Fund or underlying fund, for any reason, is unable to close out the transaction. In addition, to the extent the Fund or an underlying fund borrows money, interest costs on such borrowed money may not be recovered by any appreciation of the securities purchased with the borrowed funds and could exceed the Fund’s or underlying fund’s investment income, resulting in greater losses. The value of the Nova Fund’s, Mid-Cap 1.5x Strategy Fund’s, Russell 2000^® 1.5x Strategy Fund’s, International Equity Funds’, Strengthening Dollar 2x Strategy Fund’s, Weakening Dollar 2x Strategy Fund’s, Government Long Bond 1.2x Strategy Fund’s, and in the case of the Asset Allocation Funds, certain of the underlying funds’ shares will tend to increase or decrease more than the value of any increase or decrease in its underlying index due to the fact that the Fund’s or underlying fund’s investment strategies involve the use of leverage. Leverage will also have the effect of magnifying tracking error.

Liquidity Risk – In certain circumstances, it may be difficult for the Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, to purchase and sell particular investments within a reasonable time at a fair price. To the extent that there is

not an established retail market for instruments in which the Fund or an underlying fund may invest, trading in such instruments may be relatively inactive. In addition, during periods of reduced market liquidity or in the absence of readily available market quotations for particular investments in the Fund’s or an underlying fund’s portfolio, the ability of the Fund or an underlying fund to assign an accurate daily value to these investments may be difficult and the Advisor may be required to fair value the investments. For additional information about fair valuation, see “Calculating NAV.”

Market Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, may invest in public and privately issued securities, which may include common and preferred stocks, bonds, warrants, and rights, as well as derivatives and financial instruments that attempt to track the price movement of securities or commodities indices. Investments in securities and other financial instruments, in general, are subject to market risks that may cause their prices, and therefore the Fund’s value, to fluctuate over time. The Fund’s or an underlying fund’s investments may decline in value due to factors affecting securities or commodities markets generally, or particular countries, segments, economic sectors, industries or companies within those markets. The value of a security may decline due to general economic and market conditions which are not specifically related to a particular issuer, such as real or perceived adverse economic conditions or changes in interest or currency rates. The value of securities convertible into equity securities, such as warrants or convertible debt, also is affected by prevailing interest rates, the credit quality of the issuer and any call provision. Fluctuations in the value of securities and financial instruments in which the Fund or an underlying fund invests will cause the NAV of the Fund to fluctuate. Historically, the markets have moved in cycles, and the value of the Fund’s or an underlying fund’s securities and other financial instruments may fluctuate drastically from day to day.

Non-Diversification Risk – To the extent that the Fund invests a significant percentage of its assets in a limited number of issuers, the Fund is subject to the risks of investing in those few issuers, and may be more susceptible to a single adverse economic or regulatory occurrence. As a result, changes in the market value of a single security could cause greater fluctuations in the value of Fund shares than would occur in a diversified fund.

OTC Trading Risk – Certain of the derivatives in which the Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds invest may be traded (and privately negotiated) in the OTC market. While the OTC derivatives market is the primary trading venue for many derivatives, it is largely unregulated and lacks transparency with respect to the terms of OTC transactions. OTC derivatives are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to the Fund. In addition, such derivative instruments are often highly customized and tailored to meet the needs of the counterparties. If a derivative transaction is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price. As a result and similar to other privately negotiated contracts, the Fund is subject to counterparty credit risk with respect to such derivative contracts.

Passive Investment Risk – The Fund is not actively managed and may be affected by a general decline in market segments relating to its underlying index or benchmark. The Fund invests in securities included in, or representative of, its underlying index, regardless of their investment merits. The Advisor does not attempt to take defensive positions in declining markets. As a result, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions.

Portfolio Turnover Risk – The Fund’s strategy, or in the case of the Asset Allocation Funds, certain of the underlying funds’ strategies, may frequently involve buying and selling portfolio securities to rebalance the Fund’s or an underlying fund’s exposure to various market sectors. Higher portfolio turnover may result in the Fund or an underlying fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect.

Repurchase Agreement Risk – The Fund will enter into repurchase agreements, which are transactions in which the Fund purchases securities or other obligations from a bank or securities dealer and simultaneously commits to resell them to a counterparty at an agreed-upon date or upon demand and at a price reflecting a market rate of interest unrelated to the coupon rate or maturity of the purchased obligations. The Fund will enter into repurchase agreements only with counterparties that the Advisor believes present acceptable credit risks, and the collateral securing the repurchase agreements generally will be limited to U.S. government securities and cash. If the market value of the underlying obligations of a repurchase agreement declines, the counterparty must provide additional collateral so that at all times the value of the collateral is greater than the repurchase price of the underlying obligations. Nonetheless, should a counterparty become insolvent or otherwise default, there could be a delay before the Fund is able to liquidate the collateral, which would subject the collateral and the Fund to market risk during that period.

Agriculture Sector Risk – The risk that the securities of issuers in the agriculture sector that certain of the Asset Allocation Funds’ underlying funds purchase will underperform the market as a whole. To the extent that an underlying fund’s

investments are exposed, directly and indirectly, to the agriculture sector, the underlying fund, and thus the Asset Allocation Fund, is subject to legislative or regulatory changes, adverse market conditions and increased competition affecting the agriculture sector. In addition, investments in the agriculture sector may be highly volatile and can change quickly and unpredictably due to a number of factors, including the supply of and demand of each commodity, legislative or regulatory developments relating to food safety, political, legal, financial, accounting and tax matters and other events that the underlying fund cannot control. In addition, increased competition caused by economic recession, labor difficulties and changing consumer tastes and spending can affect the demand for agricultural products, and consequently the value of investments in that sector. As a result, the price of a direct or indirect investment in the agriculture sector could decline, which would adversely affect an investment in the underlying fund, and thus the Asset Allocation Funds, if it held such an investment.

Banking Sector Risk – The risk that the securities of issuers in the banking sector that the Banking Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the banking sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the banking sector. For example, government regulations may limit both the amounts and types of loans and financial commitments banking companies can make, and the interest rates and fees they can charge and the amount of capital they must maintain, which may affect the profitability of banking companies. Credit losses resulting from financial difficulties of borrowers also can negatively affect the performance of Banking Companies. The prices of the securities of Banking Companies may fluctuate widely due to the broadening of regional and national interstate banking powers, the reduction in the number of publicly-traded Banking Companies, and general economic conditions that could create exposure to credit losses.

Basic Materials Sector Risk – The risk that the securities of issuers in the basic materials sector that the Basic Materials Fund, U.S. Long Short Momentum Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, purchases will underperform the market as a whole. To the extent that a Fund’s or underlying fund’s investments are exposed to issuers conducting business in the basic materials sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the basic materials sector. The prices of the securities of Basic Materials Companies may fluctuate widely due to the level and volatility of commodity prices, the exchange value of the U.S. dollar, import controls, worldwide competition, liability for environmental damage, depletion of resources, and mandated expenditures for safety and pollution control devices.

Biotechnology Sector Risk – The risk that the securities of issuers in the biotechnology sector that the Biotechnology Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the biotechnology sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the biotechnology sector. The prices of the securities of Biotechnology Companies may fluctuate widely due to patent considerations, intense competition, rapid technological change and obsolescence, and regulatory requirements of the Food and Drug Administration, the Environmental Protection Agency, state and local governments, and foreign regulatory authorities.

Consumer Products Sector Risk – The risk that the securities of issuers in the consumer products sector that the Consumer Products Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the consumer products sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the consumer products sector. The performance of Consumer Products Companies has historically been closely tied to the performance of the overall economy, and also is affected by interest rates, competition, consumer confidence and relative levels of disposable household income and seasonal consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Electronics Sector Risk – The risk that the securities of issuers in the electronics sector that the Electronics Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the electronics sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of Electronics Companies may fluctuate widely due to risks of rapid obsolescence of products, intense competition, the economic performance of their customers, high technology and research costs, and may face competition from subsidized foreign competitors with lower production costs.

Energy Sector Risk – The risk that the securities of, or financial instruments tied to the performance of, issuers in the energy sector and energy sector commodities that the Energy Fund, U.S. Long Short Momentum Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, purchase will underperform the market as a whole either by declining in value or failing to perform as well. To the extent that a Funds’ or underlying funds’ investments are exposed to issuers

conducting business in the energy sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the energy and energy commodities sectors. The prices of the securities of Energy Companies and energy sector commodities may fluctuate widely due to changes in value and dividend yield, which depend largely on the price and supply of energy fuels, international political events relating to oil producing countries, energy conservation, the success of exploration projects, and tax and other governmental regulatory policies.

Energy Services Sector Risk – The risk that the securities of issuers in the energy services sector that the Energy Services Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the energy services sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the energy services sector. The prices of the securities of Energy Services Companies may fluctuate widely due to the supply and demand both for their specific products or services and for energy products in general, the price of oil and gas, exploration and production spending, governmental regulation and environmental issues, and world events and economic conditions generally affecting energy supply companies.

Financial Services Sector Risk – The risk that the securities of issuers in the financial services sector that the Financial Services Fund, U.S. Long Short Momentum Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, purchases will underperform the market as a whole. To the extent that a Fund’s or underlying fund’s investments are exposed to issuers conducting business in the financial services sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the financial services sector. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, and the interest rates and fees they can charge. Profitability is largely dependent on the availability and cost of capital funds, and can fluctuate significantly when interest rates change or due to increased competition. In addition, the recent deterioration of the credit markets generally has caused an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Recent events in the financial sector have resulted, and may continue to result, in an unusually high degree of volatility in the financial markets, both domestic and foreign, and caused certain financial services companies to incur large losses. Numerous financial services companies have experienced substantial declines in the valuations of their assets, taken action to raise capital (such as the issuance of debt or equity securities), or even ceased operations. These actions have caused the securities of many financial services companies to experience a dramatic decline in value. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition.

Health Care Sector Risk – The risk that the securities of issuers in the health care sector that the Health Care Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the health care sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the health care sector. The prices of the securities of Health Care Companies may fluctuate widely due to government regulation and approval of their products and services, which can have a significant effect on their price and availability. Furthermore, the types of products or services produced or provided by these companies may quickly become obsolete. Moreover, liability for products that are later alleged to be harmful or unsafe may be substantial, and may have a significant impact on a Health Care Company’s market value and/or share price.

Internet Sector Risk – The risk that the securities of issuers in the Internet sector that the Internet Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the Internet sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the Internet sector. The prices of the securities of Internet Companies may fluctuate widely due to competitive pressures, increased sensitivity to short product cycles and aggressive pricing, problems related to bringing their products to market and rapid obsolescence of products.

Leisure Sector Risk – The risk that the securities of issuers in the leisure sector that the Leisure Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the leisure sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the leisure sector. Securities of Leisure Companies may be considered speculative, and generally exhibit greater volatility than the overall market. The prices of the securities of Leisure Companies may fluctuate widely due to unpredictable earnings, due in part to changing consumer tastes and intense competition, strong reaction to technological developments and to the threat of increased government regulation, particularly in the gaming arena.

Precious Metals Sector Risk – The risk that the relatively few securities of, or financial instruments tied to the performance of, issuers in the mining industry that the Precious Metals Fund, and in the case of the Asset Allocation Funds, certain of the

underlying funds, purchase will underperform the market as a whole. To the extent that the Fund’s or underlying funds’ investments are exposed to issuers conducting business in the precious metals sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that industry, as well as to the volatility of global prices for precious metals. The prices of precious metals and securities of Precious Metals Companies may fluctuate widely due to changes in inflation or inflation expectations, currency fluctuations, speculation, worldwide demand and political developments in precious metals producing countries.

Real Estate Sector Risk – The risk that the securities of real estate companies that the Real Estate Fund, U.S. Long Short Momentum Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, purchase will underperform the market as a whole. To the extent that a Fund’s or underlying funds’ investments are exposed to real estate companies, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting real estate companies. Investments in real estate companies also may subject the Fund or underlying fund to the risks associated with the direct ownership of real estate. The general performance of the real estate industry has historically been cyclical and particularly sensitive to economic downturns. Changes in prevailing real estate values and rental income, interest rates and changing demographics may affect the value of securities of issuers in the real estate industry. Also, Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while Mortgage REITs may be affected by the quality of the credit extended. In addition to these risks, REITs are dependent on specialized management skills, and some REITs may have investments in relatively few properties, in a small geographic area, or a single type of property. These factors may increase the volatility of the Fund’s or underlying funds’ investments in REITs.

Retailing Sector Risk – The risk that the securities of issuers in the retailing sector that the Retailing Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the retailing sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the retailing sector. The prices of the securities of Retailing Companies may fluctuate widely due to consumer spending, which is affected by general economic conditions and consumer confidence levels. The retailing industry is highly competitive, and a Retailing Company’s success is often tied to its ability to anticipate and react to changing consumer tastes. Many Retailing Companies are thinly capitalized, and are dependent upon a relatively few number of business days to achieve their overall results.

Technology Sector Risk – The risk that the securities of issuers in the technology sector that the NASDAQ-100^® Fund, Inverse NASDAQ-100^® Strategy Fund, Technology Fund, U.S. Long Short Momentum Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, purchases will underperform the market as a whole. To the extent that a Fund’s investments are exposed to issuers conducting business in the technology sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting that economic sector. The prices of the securities of technology companies may fluctuate widely due to competitive pressures, increased sensitivity to short product cycles and aggressive pricing, problems relating to bringing their products to market, very high price/earnings ratios, and high personnel turnover due to severe labor shortages for skilled technology professionals.

Telecommunications Sector Risk – The risk that the securities of issuers in the telecommunications sector that the Telecommunications Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the telecommunications sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the telecommunications sector. The prices of the securities of Telecommunications Companies may fluctuate widely due to both federal and state regulations governing rates of return and services that may be offered, fierce competition for market share, and competitive challenges in the U.S. from foreign competitors engaged in strategic joint ventures with U.S. companies, and in foreign markets from both U.S. and foreign competitors. In addition, recent industry consolidation trends may lead to increased regulation of Telecommunications Companies in their primary markets.

Transportation Sector Risk – The risk that the securities of issuers in the transportation sector that the Transportation Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the transportation sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the transportation sector. The prices of the securities of Transportation Companies may fluctuate widely due to their cyclical nature, occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements, and insurance costs, the recent trend of government deregulation, and increased competition from foreign companies, many of which are partially funded by foreign governments and which may be less sensitive to short-term economic pressures.

Utilities Sector Risk – The risk that the securities of issuers in the utilities sector that the Utilities Fund purchases will underperform the market as a whole. To the extent that the Fund’s investments are exposed to issuers conducting business in the utilities sector, the Fund is subject to legislative or regulatory changes, adverse market conditions and/or increased competition affecting the utilities sector. The prices of the securities of Utilities Companies may fluctuate widely due to government regulation; the effect of interest rates on capital financing; competitive pressures due to deregulation in the utilities industry; supply and demand for services; increased sensitivity to the cost of natural resources required for energy production; and environmental factors such as conservation of natural resources or pollution control.

Short Sales Risk – Short sales are transactions in which the Fund or in the case of the Asset Allocation Funds, certain of the underlying funds, sell a security they do not own. To complete the transaction, the Fund or an underlying fund must borrow the security to make delivery to the buyer. The Fund or underlying fund is then obligated to replace the security borrowed by purchasing the security at the market price at the time of replacement. The price at such time may be higher or lower than the price at which the security was sold by the Fund or underlying fund. If the underlying security goes down in price between the time the Fund or underlying fund sells the security and buys it back, the Fund or underlying fund will realize a gain on the transaction. Conversely, if the underlying security goes up in price during the period, the Fund or underlying fund will realize a loss on the transaction. Any such loss is increased by the amount of premium or interest the Fund or underlying fund must pay to the lender of the security. Likewise, any gain will be decreased by the amount of premium or interest the Fund or underlying fund must pay to the lender of the security. The Fund or underlying fund also is required to segregate other assets on its books to cover its obligation to return the security to the lender which means that those other assets may not be available to meet the Fund’s or an underlying fund’s needs for immediate cash or other liquidity. The Fund’s or an underlying fund’s investment performance also may suffer if the Fund or underlying fund is required to close out a short position earlier than it had intended. This would occur if the securities lender required the Fund or underlying fund to deliver the securities the Fund or underlying fund borrowed at the commencement of the short sale and the Fund or underlying fund was unable to borrow the securities from another securities lender or otherwise obtain the security by other means. In addition, the Fund or underlying fund may be subject to expenses related to short sales that are not typically associated with investing in securities directly, such as costs of borrowing and margin account maintenance costs associated with the Fund’s or an underlying fund’s open short positions. These expenses negatively impact the performance of the Fund. For example, when the Fund or an underlying fund short sells an interest-bearing security, such as a bond, it is obligated to pay the interest on the security it has sold. This cost is partially offset by the interest earned by the Fund or underlying fund on the investment of the cash generated by the short sale. When the Fund or an underlying fund sells short an equity security that pays a dividend, the Fund or underlying fund must pay out the dividend rate of the equity security to the lender and records this as an expense of the Fund or the underlying fund and reflects the expense in its financial statements. However, a dividend paid on a security sold short generally has the effect of reducing the market value of the shorted security and thus, increases the Fund’s or an underlying fund’s unrealized gain or reduces the Fund’s or an underlying fund’s unrealized loss on its short sale transaction. To the extent that the interest rate and/or dividend that the Fund or an underlying fund is obligated to pay is greater than the interest earned by the Fund or an underlying fund on investments, the performance of the Fund or an underlying fund will be negatively impacted. These types of short sales expenses are sometimes referred to as the “negative cost of carry,” and will tend to cause the Fund or an underlying fund to lose money on a short sale even in instances where the price of the underlying security sold short does not change over the duration of the short sale.

Stable Price Per Share Risk – The Fund is subject to Stable Price Per Share Risk. The U.S. Government Money Market Fund’s assets are valued using the amortized cost method, which enables the Fund to maintain a stable price of $1.00 per share. Although the Fund is managed to maintain a stable price per share of $1.00, there is no guarantee that the price will be constantly maintained, and it is possible to lose money. The Fund is not a bank deposit and is not federally insured or guaranteed by any government agency or guaranteed to achieve its objective.

Status as a Regulated Investment Company Risk – The Fund may realize gains from the sale or other disposition of foreign currencies and other income (including but not limited to gains from options, futures or forward contracts) derived from investing in stock, securities, or foreign currencies. The Secretary of the Treasury is authorized to issue regulations that might cause the Fund, as a result of its realization of such foreign currency gains, to fail to qualify as a regulated investment company. As of the date of this Prospectus, no regulations have been issued pursuant to this authorization. It is possible, however, that such regulations may be issued in the future. Please see the Statement of Additional Information under “Special Considerations Applicable to the Funds” for additional discussion of this issue.

Tax Risk – In order for the Fund to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), the Fund must derive at least 90% of its gross income each taxable year from qualifying income (“qualifying income”), which is described in more detail in the SAI. As noted under “Commodity-Linked Derivative Investment Risk” above, certain of the Asset Allocation Funds’ underlying funds gain most of their exposure to the

commodities markets through investment in a corresponding wholly-owned Subsidiary, which may invest in commodity-linked derivative instruments and other similar instruments. Each of these underlying funds (the “CFC PLR Underlying Funds”) has received a private letter ruling issued by the Internal Revenue Service which concludes that the income attributable to each CFC PLR Underlying Fund’s investment in its corresponding Subsidiary will be “qualifying income.” The Asset Allocation Funds only invest in Funds that have private letter rulings permitting such affiliated underlying funds to utilize wholly-owned Subsidiaries (i.e., the CFC PLR Underlying Funds). As a result, no Fund invests in a Subsidiary either directly or indirectly in a circumstance other than where a private letter ruling has been obtained.

In July 2011, the IRS suspended the issuance of private letter rulings regarding the investment by registered investment companies in controlled foreign corporations which principally invest in commodities-linked derivative instruments. The IRS has indicated that it is reconsidering the position articulated in such private letter rulings and stated that it intends to issue public guidance regarding the use of controlled foreign corporations by registered investment companies to indirectly invest in commodities. As of the date of this Prospectus, it is not clear whether this guidance, if issued, will continue to permit or somehow restrict the distributions from controlled foreign corporations to be treated as “qualifying income” for purposes of the regulated investment company qualification rules. The IRS, however, has informally indicated that any guidance regarding the treatment of distributions from controlled foreign corporations will be prospective in application and provide for a transition period for affected registered investment companies. Nevertheless, the CFC PLR Underlying Funds are permitted to rely on the conclusion reached in the private letter rulings issued to them with respect to the operation of their wholly-owned Subsidiaries until such time as the IRS revokes such rulings.

The status of certain commodity-linked derivative instruments as qualifying income has been addressed in Revenue Ruling 2006-1 and Revenue Ruling 2006-31 which provide that income from commodity-linked derivative instruments in which certain of the underlying funds invest will not be considered qualifying income. To the extent the affiliated underlying funds invest in such instruments directly, the affiliated underlying funds will restrict their income from commodity-linked derivative instruments that do not generate qualifying income, such as commodity-linked swaps, to a maximum of 10% of their gross income (when combined with its other investments that produce non-qualifying income). If the Fund fails to meet the regulated investment company qualification tests, the Fund may be subject to corporate level taxes unless it is eligible for certain relief provisions under the Internal Revenue Code. The payment of such taxes would likely negatively affect the returns on the Fund.

The CFC PLR Underlying Funds have also received private letter rulings from the IRS concluding that certain commodities-linked notes held by the CFC PLR Underlying Funds will produce “qualifying income” for purposes of the regulated investment company qualification tests. The Advisor intends to conduct all affiliated underlying funds’ investments in commodity-linked notes in a manner consistent with the terms and conditions of these private letter rulings.

Temporary Defensive Investment Risk – The Fund may be affected by a general decline in market specific market segments or the market as a whole. The Fund invests in securities included in a specific market segment, such as the commodity and financial futures markets, in an effort to achieve its investment objective and regardless of their investment merits. The Advisor does not attempt to take defensive positions in declining markets. As a result, the Fund may be subject to greater losses in a declining market than a fund that does take defensive positions.

Tracking Error Risk – The Advisor may not be able to cause the Fund’s performance to match or correlate to that of the Fund’s benchmark, either on a daily or aggregate basis. Factors such as Fund expenses, imperfect correlation between the Fund’s investments and those of its underlying index, rounding of share prices, changes to the composition of the underlying index, regulatory policies, high portfolio turnover rate, and the use of leverage all contribute to tracking error. Tracking error may cause the Fund’s performance to be less than you expect.

In addition, because the Nova Fund, S&P 500 Fund, Inverse S&P 500 Strategy Fund, NASDAQ-100^® Fund, Inverse NASDAQ-100^® Strategy Fund, Inverse Mid-Cap Strategy Fund, Russell 2000^® Fund, Inverse Russell 2000^® Strategy Fund, Inverse Government Long Bond Strategy Fund, S&P 500 Pure Growth Fund, S&P 500 Pure Value Fund, S&P MidCap 400 Pure Growth Fund, S&P MidCap 400 Pure Value Fund, S&P SmallCap 600 Pure Growth Fund, S&P SmallCap 600 Pure Value Fund, Strengthening Dollar 2x Strategy Fund, and Weakening Dollar 2x Strategy Fund is tracking the performance of its benchmark on a daily basis, mathematical compounding may prevent the Fund from correlating with the monthly, quarterly, annual or other period performance of its benchmark. Tracking error may cause the Fund’s performance to be less than you expect.

The Europe 1.25x Strategy Fund, Japan 2x Strategy Fund and Government Long Bond 1.2x Strategy Fund seek to track their respective benchmarks over time, but are also subject to the effects of mathematical compounding. Tracking error may be more significant for the Europe 1.25x Strategy Fund, Japan 2x Strategy Fund and Government Long Bond 1.2x Strategy Fund compared to other Funds due to the Funds’ consistent application of leverage to increase exposure to their respective underlying indices.

The prices of the Europe 1.25x Strategy Fund and Japan 2x Strategy Fund are calculated at the close of the U.S. markets using fair value prices. Due to the differences in times between the close of the European and Japanese markets and the time the Funds price their shares, the value the Funds assign to securities generally will not be the same as the quoted or published prices of those securities on their primary markets or exchanges. On a daily basis, the Funds are priced with consideration to the performance of securities on their primary exchanges, foreign currency appreciation/depreciation, and market movement in the U.S. as related to the securities. As a result, the tracking error risk for the Europe 1.25x Strategy Fund and Japan 2x Strategy Fund may be higher than for other Funds.

Trading Halt Risk – The Fund, and in the case of the Asset Allocation Funds, certain of the underlying funds, typically will hold short-term options and futures contracts. The major exchanges on which these contracts are traded, such as the Chicago Mercantile Exchange, have established limits on how much an option or futures contract may decline over various time periods within a day. In addition, the major securities exchanges, such as the NYSE, have established limits on how much the securities market, based on the Dow Jones Industrial Average^SM, may decline over various time periods within a day. If the price of a security, an option or a futures contract declines more than the established limits, trading on the exchange is halted on that instrument. If a trading halt occurs, the Fund or an underlying fund may temporarily be unable to purchase or sell the options, futures contracts or securities that are the subject of the trading halt. Such a trading halt near the time the Fund or an underlying fund prices its shares may limit the Fund’s or an underlying fund’s ability to use leverage and may prevent the Fund or an underlying fund from achieving its investment objective. In such an event, the Fund or an underlying fund also may be required to use a “fair value” method to price its outstanding contracts or securities.

Value Stocks Risk – Value stocks tend to be inexpensive relative to their earnings or assets compared to other types of stocks. Over time, a value investing style may go in and out of favor, causing the Fund to sometimes underperform other equity funds that use different investing styles. Value stocks can react differently to issuer, political, market and economic developments than the market overall and other types of stock. In addition, the Fund’s value approach carries the risk that the market will not recognize a security’s intrinsic value for a long time or that a stock judged to be undervalued may actually be appropriately priced.

A description of the Funds’ policies and procedures with respect to the disclosure of Fund portfolio securities is available in the SAI.

The Event Driven and Distressed Strategies Fund and Long Short Equity Strategy Fund employ investment methodologies that are similar to those used to compile the indices and benchmarks described below.

Credit Suisse Event Driven Liquid Index – The Credit Suisse Event Driven Liquid Index aims to synthetically replicate the performance of the Dow Jones Credit Suisse Event Driven Hedge Fund Index, which is non-investable, by using non-hedge fund, liquid tradable securities selected and weighted according to an algorithm. The Dow Jones Credit Suisse Event Driven Hedge Fund Index is an asset-weighted index containing event driven hedge fund constituents. Event driven hedge funds generally make short and long investments in the securities of corporations experiencing substantial change as a result of such corporate actions as liquidation, bankruptcy, emergence from bankruptcy, divestitures, acquisitions, or mergers. Event driven hedge funds may specialize in distressed debt, distressed equities, Regulation D transactions, capital structure arbitrage, merger arbitrage or other special situations, or they may invest across multiple event driven strategies. Such strategies typically involve buying long or selling short certain securities in the capital structures of various corporations representing a broad range of both debt and equity securities.

The Dow Jones Credit Suisse Event Driven Hedge Fund Index is compiled by Credit Suisse Hedge Index LLC. It is an asset-weighted hedge fund index and includes only hedge funds, as opposed to separate accounts. The Index uses the funds classified as event driven in the Credit Suisse database, which tracks over 5,000 hedge funds, and consists only of hedge funds with a minimum of US $50 million under management, a 12-month track record, and audited financial statements. It is calculated and rebalanced on a monthly basis, and shown net of all performance fees and expenses. It is the exclusive property of Credit Suisse Hedge Index LLC.

Merrill Lynch Factor Model – The Merrill Lynch Factor Model (the “Model”) is designed to provide a high correlation to “hedge fund beta,” the portion of hedge fund returns that can be explained by exposure to certain market measures, and not individual manager skill. The value of the Model changes based on the weighted performance of well-known, liquid index components such as the S&P 500^® Index, Russell 2000^® Index, MSCI EAFE Index, MSCI Emerging Markets Index, USD-Euro Spot Exchange Rate and One Month Libor Index (each, a “Model Factor”).

The Model uses a proprietary rules-based, discretion-free regression model developed by Merrill Lynch to allocate to the Model Factors in an attempt to provide a high correlation to hedge fund beta.

The respective component weightings of the Model are rebalanced monthly. The rebalance is driven by the Model. Exposures to market measures can be positive (long) or negative (short), except for the MSCI Emerging Markets Free Total Return, which can only be long.

Credit Suisse Long/Short Liquid Index – The Credit Suisse Long/Short Liquid Index aims to synthetically replicate the performance of the Dow Jones Credit Suisse Long/Short Equity Hedge Fund Index, which aggregates a broad universe of long/short equity hedge funds and is non-investable, by using non-hedge fund, liquid tradable securities. The Dow Jones Credit Suisse Long/Short Equity Hedge Fund Index is an asset-weighted hedge fund index containing long/short equity hedge fund constituents. Long/short equity hedge funds generally buy equities that are expected to increase in value and sell short equities that are expected to decrease in value, and often attempt to diversify or hedge exposure to particular market sectors, regions, or market capitalization. Long/short equity funds may be net long or net short.

The Dow Jones Credit Suisse Long/Short Equity Hedge Fund Index is compiled by Credit Suisse Hedge Index LLC. It is an asset-weighted hedge fund index and includes only funds, as opposed to separate accounts. The Index uses the Credit Suisse database, which tracks over 5000 funds, and consists only of funds with a minimum of US $50 million under management, a 12-month track record, and audited financial statements. It is calculated and rebalanced on a monthly basis, and shown net of all performance fees and expenses. It is the exclusive property of Credit Suisse Hedge Index LLC.

More detailed information about the Funds’ comparable indices can be found on the Credit Suisse and Merrill Lynch websites and in the SAI under “More Information About the Comparable Indices.”

The Advisor, Security Investors, LLC, is located at 805 King Farm Boulevard, Suite 600, Rockville, Maryland 20850, and serves as investment adviser of the Funds. The Advisor has served as the investment adviser of each Fund since each its inception.

The Advisor makes investment decisions for the assets of the Funds and continuously reviews, supervises, and administers each Fund’s investment program. The Board of Trustees of the Trust supervises the Advisor and establishes policies that the Advisor must follow in its day-to-day management activities. Pursuant to an investment advisory agreement between the Trust and the Advisor, the Funds paid the Advisor a fee at an annualized rate for the fiscal year ended March 31, 2012 based on the average daily net assets of each Fund, as set forth below:

The Long Short Interest Rate Strategy Fund is sub-advised by the Fund’s Sub-Advisor, American Independence Financial Services, LLC. The Advisor pays the Sub-Advisor out of the advisory fee it receives.

As part of its agreement with the Trust, the Advisor will pay all expenses of the Asset Allocation Funds, including the cost of transfer agency, custody, fund administration, legal, audit and other services, except interest expense, acquired fund fees and expenses, and taxes (expected to be de minimis), brokerage commissions and other expenses connected with the execution of portfolio transactions, short sales dividend and interest expenses and extraordinary expenses.

The Advisor has contractually agreed to reduce fees and/or reimburse expenses to the extent necessary in order to keep net expenses (excluding interest, taxes, brokerage commissions, Acquired Fund Fees and Expenses, and dividends on securities sold short, and extraordinary expenses) from exceeding the Event Driven and Distressed Strategies Fund’s and Long Short Equity Strategy Fund’s average daily net assets as follows:

The above contractual fee waivers will be honored by the Advisor through July 31, 2013. The fee waivers may be renewed by the Advisor for subsequent periods thereafter. To maintain these expense limits, the Advisor may reduce a portion of its management fees and/or reimburse certain expenses of the Funds. This Agreement may be terminated only with the approval of the Funds’ Board of Trustees. In any event, this undertaking will continue for at least twelve months from the date of this Prospectus.

For the U.S. Government Money Market Fund, the Advisor and/or one or more of its affiliates may reimburse expenses or waive fees of the Fund to the extent necessary to maintain the Fund’s net yield at a certain level as determined by the Advisor. Any such waiver or expense reimbursement would be voluntary and could be discontinued at any time. There is no guarantee that the Fund will be able to avoid a negative yield or continue paying periodic dividends when the yield is not positive.

The Advisor bears all of its own costs associated with providing these advisory services and the expenses of the members of the Board of Trustees who are affiliated with the Advisor. In addition, the Advisor may make payments from its own resources to broker-dealers and other financial institutions, including to the Advisor’s parent company, Guggenheim Capital, LLC and its affiliates, in connection with services provided to the Funds and for services provided in connection with the sale of Fund shares.

A discussion regarding the basis for the Board’s August 2011 approval of the Funds’ investment advisory agreement is available in the September 30, 2011 Semi-Annual Report to Shareholders, which covers the period April 1, 2011 to September 30, 2011.

For each Fund, except the Nova Fund, Inverse S&P 500 Strategy Fund, NASDAQ-100^® Fund, Inverse Mid-Cap Strategy Fund, S&P 500 Pure Growth Fund, S&P 500 Pure Value Fund, S&P MidCap 400 Pure Value Fund, S&P SmallCap 600 Pure Value Fund, Basic Materials Fund, Health Care Fund, Internet Fund, Retailing Fund, Transportation Fund, Japan 2x Strategy Fund, Strengthening Dollar 2x Strategy Fund, Weakening Dollar 2x Strategy Fund, Real Estate Fund, Inverse Government Long Bond Strategy Fund, Inverse High Yield Strategy Fund, Long Short Interest Rate Strategy Fund, and All-Asset Moderate Strategy Fund, the Advisor may hire one or more sub-advisers to oversee the day-to-day activities of the Funds. The sub-advisers are subject to oversight by the Advisor. The Advisor and the Trust have obtained an exemptive order from the U.S. Securities and Exchange Commission (the “SEC”), and obtained shareholder approval with respect to the Funds referenced, that permits the Advisor, with the approval of the Independent Trustees of the Trust, to retain unaffiliated investment sub-advisers for the Funds without submitting the sub-advisory agreement to a vote of the Funds’ shareholders. The Trust will notify shareholders in the event of any change in the identity of such sub-adviser or sub-advisers. The Advisor has ultimate responsibility for the investment performance of the Funds due to its responsibility to oversee each sub-adviser and recommend their hiring, termination and replacement. The Advisor is not required to disclose fees paid to any sub-adviser retained pursuant to the order.

The Sub-Advisor, an SEC registered investment adviser, is located at 335 Madison Avenue, Mezzanine, New York, New York 10017, and serves as investment sub-adviser to the Long Short Interest Rate Strategy Fund. The Sub-Advisor constructs and provides the Advisor with the Long Short Interest Rate Strategy Fund’s investment model via electronic signals.

A discussion regarding the basis for the Board’s August 2011 approval of the Long Short Interest Rate Strategy Fund’s investment sub-advisory agreement is available in the September 30, 2011 Semi-Annual Report to Shareholders, as amended, which covers the period March 31, 2011 to September 30, 2011.

The Funds are managed by a team of investment professionals, and on a day-to-day basis, the three individuals listed below are jointly and primarily responsible for the day-to-day management of each Fund (except for the Long Short Interest Rate Strategy Fund).

Additional information about the portfolio managers’ compensation, other accounts managed by the portfolio managers, and the portfolio managers’ ownership of securities in the Funds is available in the SAI.

The price at which you buy, sell and exchange shares is the net asset value per share, which also is known as NAV.

Each Fund, except for the S&P 500 Fund, Russell 2000^® Fund, Emerging Markets 2x Strategy Fund and Inverse Emerging Markets 2x Strategy Fund, calculates NAV once each Business Day as of the regularly scheduled close of normal trading on the NYSE (normally, 4:00 p.m., Eastern Time). The S&P 500 Fund, Russell 2000^® Fund, Emerging Markets 2x Strategy Fund and Inverse Emerging Markets 2x Strategy Fund calculate NAV twice each Business Day, first in the morning and again in the afternoon, on each day that the NYSE is open for trading. The S&P 500 Fund’s, Russell 2000^® Fund’s, Emerging Markets 2x Strategy Fund’s and Inverse Emerging Market 2x Strategy Fund’s morning NAV is calculated as of 10:45 a.m., Eastern Time and the Funds’ afternoon NAV is calculated as of the regularly scheduled close of normal trading on the NYSE (normally, 4:00 p.m., Eastern Time).

If the NYSE closes early – such as on days in advance of holidays generally observed by the NYSE – the Funds will calculate NAV as of the earlier closing time in accordance with the policies set forth in the Funds’ SAI. In addition, if the NYSE closes early the S&P 500 Fund, Russell 2000^® Fund, Emerging Markets 2x Strategy Fund, and Inverse Emerging Markets 2x Strategy Fund will calculate NAV only once and will not calculate the morning NAV. These dates are listed in the SAI. For more information on these early closings, please call 800.820.0888 or visit the Guggenheim Investments website – www.rydex-sgi.com.

In calculating NAV, the Funds, except for the International Equity Funds and Asset Allocation Funds, generally value their investment portfolios based on the market price of the securities as of the time the Funds determine NAV. If market prices are unavailable or the Advisor thinks that they are unreliable, the Advisor prices those securities at fair value as determined in good faith using methods approved by the Board of Trustees. For example, market prices may be unavailable if trading in a particular portfolio security was halted during the day and did not resume prior to a Fund’s NAV calculation. The Advisor may view market prices as unreliable when the value of a security has been materially affected by events occurring after the market closes, but prior to the time as of which the Funds calculate NAV. The Asset Allocation Funds generally value shares of the underlying funds at their NAV and other investments at market prices.

The International Equity Funds generally value their assets at fair value using procedures approved by the Board of Trustees because of the time difference between the close of the relevant foreign exchanges and the time the Funds price their shares at the close of the NYSE. As such, the value assigned to the Funds’ securities may not be the quoted or published prices of those securities on their primary markets or exchanges.

The Advisor will regularly value the Event Driven and Distressed Strategies Fund’s and Long Short Equity Strategy Fund’s investments in structured notes and swap agreements at fair value and other investments at market prices.

The use of fair valuation in pricing a security involves the consideration of a number of subjective factors and therefore, is susceptible to the unavoidable risk that the valuation may be higher or lower than the price at which the security might actually trade if a reliable market price were readily available.

The underlying funds in which the Asset Allocation Funds invest have transaction cut-off times that are prior to the Funds’ transaction cut-off times. Accordingly, on a daily basis, the Funds’ purchase, sale or exchange of underlying fund shares may not occur until the close of normal trading on the NYSE the day after the initial purchase order is entered. The resulting delay may have a negative impact on the performance of the Funds.

The U.S. Government Money Market Fund values its assets using the amortized cost method of valuation pursuant to procedures approved by the Fund’s Board of Trustees.

More information about the valuation of the Fund’s holdings and the amortized cost method can be found in the SAI.

Acquired Fund Fees and Expenses – As a shareholder in other investment companies, which may include other mutual funds, closed-end funds, and business development companies (the “Acquired Funds”), a Fund may indirectly bear its proportionate share of the fees and expenses of the Acquired Funds. “Acquired Fund Fees and Expenses” are based upon (i) the approximate allocation of the Fund’s assets among the Acquired Funds and (ii) the net expenses (excluding interest, taxes and extraordinary expenses) of the Acquired Funds during their most recently completed fiscal year. “Acquired Fund Fees and Expenses” are not direct costs paid by Fund shareholders and do not affect the calculation of the Fund’s net asset value or the Fund’s cost of operations. “Acquired Fund Fees and Expenses” will vary with changes in the expenses of the Acquired Funds, as well as allocation of the Fund’s assets, and may be higher or lower than those shown.

Short Sales Dividend and Interest Expense – “Short Sales Dividend and Interest Expense” is incurred when the Fund short sells a security to gain the inverse exposure necessary to meet its investment objective. The Fund must pay out the dividend rate on an equity security, the coupon rate of a fixed income security, and interest expense associated with either, to the lender and records these as an expense of the Fund and reflects these expenses in its financial statements. However, any such dividend or interest expense on a security sold short generally has the effect of reducing the market value of the shorted security – thus increasing the Fund’s unrealized gain or reducing the Fund’s unrealized loss on its short sale transaction. “Short Sales Dividend and Interest Expense” is not a fee charged to the shareholder by the Advisor or other service provider. Rather it is more similar to the transaction costs or capital expenditures associated with the day-to-day management of any mutual fund.

Advisor Class Shares. Advisor Class Shares are sold principally to clients of professional money managers (“financial intermediaries”) who (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into agreement with the principal underwriter to offer Advisor Class Shares through a no-load network or platform, and to investors who take part in certain asset allocation investment programs.

Investor Class Shares and H-Class Shares. Investor Class Shares and H-Class Shares are offered directly through Rydex Fund Services, LLC and also through authorized securities brokers and other financial intermediaries.

U.S. Government Money Market Fund Shares. Shares of the U.S. Government Money Market Fund are sold principally to clients of professional money managers (“financial intermediaries”) who (i) charge such clients an ongoing fee for advisory, investment, consulting or similar services, or (ii) have entered into agreement with the principal underwriter to offer Advisor Class Shares through a no-load network or platform, and to investors who take part in certain asset allocation investment programs. Shares of the U.S. Government Money Market Fund also are offered directly through Rydex Fund Services, LLC and also through authorized securities brokers and other financial intermedaries.

You will need to open a Guggenheim Investments shareholder account to make share transactions – buy, sell or exchange shares of the Funds directly with Guggenheim Investments. You can obtain an account application or request more information about opening an account by calling Guggenheim Investments Client Services at 800.820.0888 or 301.296.5100. You also may visit the “Customer Service Center” tab of www.rydex-sgi.com.

For investors without a financial professional, you must transfer an existing IRA (or multiple IRAs) in order to meet the minimum investment amount requirements applicable to IRA accounts held at Guggenheim Investments. Investors with a financial professional should refer to the “Buying Fund Shares” and “Selling Fund Shares” sections of this Prospectus.

The type of application you will need depends on the type of account you want to open. For example, if you are opening a retirement account, such as an IRA, you will need to complete a different application than you would if you were opening a taxable account. When you call Guggenheim Investments to request an account application, be sure to let the Client Services representative know what type of account you want to open to ensure that you receive the correct application.

If you open your account through a broker or other financial intermediary, your financial intermediary will ordinarily assist you in completing the necessary application to open your account.

This section provides important information about the procedures that you must follow when you buy, sell or exchange shares of the Funds. You may submit transaction orders to buy, sell or exchange Fund shares on any Business Day. On any day that the NYSE closes early – or as otherwise permitted by the SEC – the Funds reserve the right to advance the time that NAV is calculated and, correspondingly, the time by which purchase and redemption orders must be received. On any day that the Funds calculate NAV earlier than normal, Guggenheim Investments reserves the right to advance the time on that day by which shareholder transaction orders must be received by the transfer agent. The NYSE holiday schedule is included in the SAI and Guggenheim Investments will post advance notice of early NYSE and Bond Market closings at www.rydex-sgi.com.

Notwithstanding the foregoing, the U.S. Government Money Market Fund reserves the right to accept orders to purchase or redeem shares on any day that is not a Business Day and the Federal Reserve Bank of New York or National Securities Clearing Corporation remains open. In addition, the U.S. Government Money Market Fund may designate special hours of operation on any such day. In the event that the U.S. Government Money Market Fund invokes the right to accept orders to purchase or redeem shares on any day that is not a Business Day and/or adopt special hours of operation, the U.S. Government Money Market Fund will post advance notice of these events at www.rydex-sgi.com.

All shareholder transaction orders are processed at the NAV next determined after your transaction order is received with all of the necessary information, sometimes referred to as “good order,” by the Funds’ transfer agent, Rydex Distributors, LLC (the “Distributor”), or authorized dealer. The following transaction cut-off times have been established in order to allow the transfer agent appropriate time to report the current day’s trading activity to the Advisor. Any application that is sent to the transfer agent does not constitute a purchase order until the transfer agent processes the application and receives correct payment by check, wire transfer or ACH.

Some intermediaries may not offer intra-day trading or pricing regardless of when you place your order with your intermediary. All orders received in good order by a financial intermediary that does not offer intra-day pricing will be priced at the Funds’ afternoon NAV. For more information about your financial intermediary’s rules and procedures, you should contact your intermediary directly.

If you opened your account through a financial intermediary, you will ordinarily submit your transaction orders through that financial intermediary, which may have its own rules about share transactions, and may have earlier cut-off times for processing your transaction order. Your financial intermediary is responsible for ensuring that your transaction order is in good order, and promptly transmitting your order to the Funds. Transaction orders received in good order by your financial intermediary will be processed at the Funds’ next determined NAV. Financial intermediaries may charge fees for the services they provide to you in connection with processing your transaction order or maintaining your account with them. Each financial intermediary also may have its own rules about minimum initial investment amounts, minimum account balances, share transactions and limits on the number of share transactions you are permitted to make in a given time period. Not all financial intermediaries are authorized to sell shares of the Funds. For more information about your financial intermediary’s rules and procedures, you should contact your financial intermediary directly.

Each Fund offers its shares continuously and investors may submit purchase orders to buy shares on any Business Day. However, Guggenheim Investments reserves the right to reject or refuse, in whole or in part, any purchase order for Fund shares within three business days of Guggenheim Investments receiving the purchase order. Purchase orders are subject to the Funds’ transaction cut-off times and will be processed at the NAV next determined after your purchase order is received in good order. For information regarding the minimum initial investment amount applicable to purchases of Advisor Class Shares, Investor Class Shares, and H-Class Shares of the Funds, please see the Funds’ summary sections earlier in this Prospectus.

Shares acquired on or after January 1, 2012 are generally considered covered shares. The Fund must report cost basis information to you and the Internal Revenue Service (“IRS”) when covered shares are redeemed. The Fund will use a default average cost method for reporting your cost basis for covered shares, unless you instruct us to use another method. If you wish to choose another default cost basis method for your account you may select among FIFO (“first-in-first-out”), LIFO (“last-in-first-out”) and HIFO (“highest-cost-in-first-out”). For redemptions of shares acquired before January 1, 2012 (“non-covered shares”), the Fund is not required to report cost basis information to you or the IRS.

Accounts opened through a financial intermediary may be subject to different cost basis method policies. For more information about your financial intermediary’s rules and procedures, you should contact your financial intermediary directly.

Fund shareholders should consult with their tax advisers to determine the best IRS-accepted cost basis method for their tax situation and to obtain more information about the new cost basis reporting laws applies to them. For more information, please see “Cost Basis.”

For additional discussion of the average cost method, see “Redemption Procedures.”

The Funds offer you the option to submit purchase orders through your financial intermediary or send purchase orders by mail, fax or internet and send purchase proceeds by check, wire transfer or ACH to the Funds for accounts opened directly. The Funds do not accept cash or cash equivalents (such as travelers’ checks and money orders), starter checks, or checks drawn on a line of credit (including credit card convenience checks). The Funds typically do not accept third-party checks. Fund management reserves the right

to refuse other payment instruments if, in the sole discretion of Fund management, it is deemed to be in the best interest of the Funds. Any payment instrument not accepted generally will be returned to you within twenty-four (24) hours of Fund management’s determination to not accept such instrument, but in no event later than three business days after such determination.

Retirement contributions will be considered as current year contributions unless otherwise instructed in writing at the time of the contribution.

You may buy shares and send your purchase proceeds by any of the following methods:

Guggenheim Investments will ordinarily cancel your purchase order under the following circumstances:

If your purchase order is cancelled for any of these reasons, you will not be entitled to benefit from any increase in NAV that the Fund(s) may have experienced from the time of your order to the time of its cancellation. In addition, if the Fund(s) NAV decreases in value from the time of your order to the time of its cancellation, the Fund(s) will hold you liable for any losses that it incurs as a result of your cancelled order.

Each Fund redeems its shares continuously and investors may sell their shares back to the Fund on any Business Day. You may redeem all or any portion of your Fund shares at the Fund’s next determined NAV calculated after your redemption order is received in good order by the transfer agent or your financial intermediary.

The Funds may suspend your right to redeem your shares during times when trading on the NYSE is suspended or restricted, or otherwise as permitted by the SEC. The Funds reserve the right to pay all or part of your redemption proceeds in liquid securities with a market value equal to the redemption price. If a Fund redeems your shares in kind, you may bear transaction costs and will bear market risks until such time as such securities are converted to cash.

You will ordinarily submit your transaction order through your financial intermediary or other securities dealers through which you opened your shareholder account. If you opened your account directly with the Funds, you may send redemption orders to Guggenheim Investments by:

Whether you transmit your redemption order by mail, fax or telephone, you must include the following information in your redemption order:

You may only place a redemption order if you are the registered owner of the account or the registered owner has given Guggenheim Investments written authorization to allow you to make redemptions from the account. You will receive a confirmation number for your redemption. Please retain it for your records.

If shareholders choose not to use the default cost basis method of average cost, such shareholders must choose a default cost basis method among FIFO, LIFO or HIFO with respect to their account. Shareholders who choose not to use the default cost basis method (i.e., the average cost basis method) may instead specifically identify the shares to be sold at the time of redemption or exchange. Shareholders using the specific identification method are expected to provide lot selection information along with their redemption or exchange request. For situations where shareholders are unable to or do not provide instructions (i.e., systematic withdrawals and other non-shareholders generated activity) the account level default will be used. Shareholders who wish to use the specific identification method for identifying lots of shares sold, however, are not permitted to use the average cost basis method.

Unless requested otherwise at the time of the transaction, the Fund will redeem or exchange shares in the following order: undated non-covered shares, non-covered shares, followed by covered shares using the method in effect for the account.

Fund shareholders should consult their tax advisers to determine the best IRS-accepted cost basis method for their tax situation and to obtain more information about how the new cost basis reporting laws applies to them. For more information see “Cost Basis.”

Distributions from your tax-qualified plan or individual retirement account (IRA) may have adverse tax consequences to you. You should consult your tax adviser before redeeming shares and making distributions from your tax-qualified plan or IRA account. All requests for distributions of redemption proceeds from tax-qualified plan and IRA accounts must be in writing. All distributions from tax-qualified plans and IRAs are subject to tax withholding rules.

Distributions from 403(b) accounts may require employer or plan administrator approval.

Your redemption proceeds normally will be sent within seven days of the transfer agent receiving your request. For redemption orders that settle on federal bank holidays, your redemption proceeds will be sent on the next Business Day following the holiday. For investments made by check or ACH (not wire purchases), purchases will be on hold for 10 business days before a payment of redemption proceeds may be made.

All redemptions will be mailed to your address of record, sent electronically via ACH, or wired to your bank account of record. You may request overnight mail service for an additional fee. If redemption proceeds are transmitted by ACH or wire and the payee instructions are not valid, the proceeds may be re-invested into shares of the U.S. Government Money Market Fund as of the date of the redemption. If you are setting up new alternate payee instructions (check) or new bank instructions (ACH or wire) the request must be in writing, include a signature guarantee, and may not be faxed. If you request proceeds to be sent to an address of record that has been changed within the previous 10 business days, a signature guarantee also is required and may not be faxed. For certain exceptions (e.g., accounts managed by financial professionals and requests to transfer between accounts), you may not be required to provide a signature guarantee. Please contact Guggenheim Investments Client Services at 800.820.0888 if you have any questions about your redemption request.

Signature guarantees help protect you and your account against fraud. You can obtain a signature guarantee at most banks and financial intermediaries. A notary public cannot provide a signature guarantee. You may not use fax to transmit a signature guarantee to the Funds.

Any dividend, capital gain or partial redemption check that has remained outstanding for a period of 90 days from the issuance date will be canceled and re-issued. If a re-issued check is not cashed within 90 days, the check will be canceled and the proceeds will be deposited into the shareholder’s account as of the cancellation date.

For dividend and capital gain checks, the proceeds will be reinvested into the appropriate share class of the Fund from which such distribution was paid, or if the Fund position has subsequently been redeemed in full, the distribution will be reinvested into shares of the U.S. Government Money Market Fund. The account also will have the distribution payout option adjusted so that all future distributions are reinvested into the appropriate share class of the Fund from which the distribution would have been paid.

For partial redemption checks, the proceeds will be deposited into shares of the U.S. Government Money Market Fund.

Any full redemption check (one that brings your account balance to $0.00) that has remained outstanding for a period of 90 days from the issuance date will be cancelled and re-issued one time.

Any redemption check from a retirement account (IRA, Roth, SEP, for example) that has remained outstanding for a period of 90 days from the issuance date will be cancelled and re-issued one time.

For checks returned in the mail, the Funds will attempt to contact the client. If no contact is made, the check will be processed according to the procedures mentioned above.

If you hold shares directly, you may redeem shares from the U.S. Government Money Market Fund by writing drafts for $100 or more on your existing account. The drafts may be made payable to any person or entity and your account will continue to earn dividends until the draft clears. Drafts may not be used for electronic funds transfers (i.e., electronic bill payments or ACH). If your balance in the U.S. Government Money Market Fund is insufficient to cover the amount of your draft, the transfer agent will automatically exchange sufficient funds from your Guggenheim Investments fund with the highest account balance to cover the draft.

You can obtain a check signature card and apply for draft writing privileges by calling Guggenheim Investments Client Services at 800.820.0888. Because of the difficulty of determining in advance the exact value of your Fund account, you may not use a draft to close your account. There is no fee for the draft writing privilege, but if payment on a draft is stopped upon your request, or if the draft cannot be honored because of insufficient funds or other valid reasons, you may be charged a fee by the financial institution where you presented your draft for payment. Guggenheim Investments also may charge a $25 fee for a draft that cannot be honored due to insufficient funds. The U.S. Government Money Market Fund may suspend the draft writing privilege at any time.

To offset the administrative expense of servicing small accounts, the Funds may impose, without additional notice, an administrative fee of $15 per year during periods where your account balance falls below the account minimum requirements for any reason. The Funds may redeem your shares if the value of your account falls below the required minimum account balance. However, the Funds will provide you with at least 30 days’ written notice to allow you sufficient time to add to your account and avoid the redemption of your shares.

An exchange is when you sell shares of one fund and use the proceeds from that sale to purchase shares of another fund. Investors may make exchanges on any Business Day of Advisor Class Shares, Investor Class Shares or H-Class Shares of any Rydex Series Fund or Rydex Dynamic Fund for Advisor Class Shares, Investor Class Shares, or H-Class Shares of any other Rydex Series Fund or Rydex Dynamic Fund, as applicable, on the basis of the respective NAVs of the shares involved. Investors also may make exchanges on any Business Day of Advisor Class Shares, Investor Class Shares or H-Class Shares of any Rydex Series Fund or Rydex Dynamic Fund for shares of the U.S. Government Money Market Fund.

For the U.S. Government Money Market Fund, investors may make exchanges on any Business Day of shares of the Fund for shares of any class of any other fund in the Guggenheim Investments family of funds, on the basis of the respective NAVs of the shares involved. The Guggenheim Investments family of funds currently includes each series of Rydex Series Funds and Rydex Dynamic Funds (collectively, the “Rydex Funds”), and the Security Equity Fund, the Security Large Cap Value Fund, the Security Mid Cap Growth Fund, and the Security Income Fund (collectively, the “Security Funds”). For more information about the Security Funds’ exchange privileges with the U.S. Government Money Market Fund, please read the Security Funds Prospectus, which is available by calling Guggenheim Investments Client Services at 800.020.0888 or 301.296.5100 or visiting the Guggenheim Investments website at www.rydex-sgi.com. Exchanges of Fund shares for shares of another Guggenheim Investments fund will be subject to the purchaser eligibility requirements of the applicable share class of that Guggenheim Investments fund, which may include initial investment amount and account balance requirements, as disclosed in that Guggenheim Investment fund’s prospectus.

Exchange requests, like any other share transaction, will be processed at the NAV next determined after your exchange order is received in good order. Exchanges involving other funds not included in this Prospectus may be subject to different transaction cut-off times. All exchange requests must be received by the Funds’ transfer agent or your financial intermediary prior to the cut-off time of the fund you are exchanging out of or the fund you are exchanging into, whichever is earlier, to be processed at that Business Day’s NAV.

While many of the Rydex Series Funds offer unlimited exchange privileges with no minimum holding periods or transaction fees, certain funds in the Guggenheim Investments family of funds do not allow unlimited trading. If you are contemplating an exchange for shares of any fund not offered in this Prospectus, you should obtain and review that fund’s current prospectus before making the exchange. You can obtain a prospectus for any fund not offered in this Prospectus by calling 800.820.0888 or 301.296.5100 or visiting the Guggenheim Investments website at www.rydex-sgi.com.

You will ordinarily submit your transaction order through your financial intermediary or other securities dealers through which you opened your shareholder account. If you opened your account directly with the Funds you may send exchange requests to Guggenheim Investments by:

Whether you transmit your exchange request by mail, fax, telephone or internet, you must include the following information in your exchange request:

You may only place exchange orders if you are the registered owner of the account or the registered owner has given Guggenheim Investments written authorization to allow you to trade the account. You will receive a confirmation number for your exchange. Please retain it for your records.

Shareholders may elect to engage in dollar-cost averaging, which allows shareholders to make periodic exchanges of shares from one fund to one or more other funds at regular intervals. With dollar-cost averaging, the cost of the securities is averaged over time and possibly over various market cycles. Dollar-cost averaging does not guarantee profits, nor does it assure that a shareholder will not have losses.

Shareholders should contact Guggenheim Investments Client Services to enroll in dollar-cost averaging. Shareholders will need to choose whether amounts are to be exchanged on the basis of a specific dollar amount or a specific number of shares. Guggenheim Investments will exchange shares as requested on the date of your choosing. If the date selected falls on a weekend or holiday, your request will be processed on the previous business day.

The Advisor will make exchanges until the value of the shareholder’s account is depleted or until the shareholder instructs Guggenheim Investments to terminate dollar-cost averaging. Dollar-cost averaging may be terminated at any time by a shareholder by written request or by phone.

Federal regulations may require the Funds to obtain your name, your date of birth (for a natural person), your residential street address or principal place of business and your Social Security Number, Employer Identification Number or other government issued identification when you open an account. Additional information may be required in certain circumstances or to open accounts for corporations or other entities. The Funds may use this information to attempt to verify your identity. The Funds may not be able to establish an account if the necessary information is not received. The Funds also may place limits on account transactions while they are in the process of attempting to verify your identity. Additionally, if the Funds are unable to verify your identity after your account is established, the Funds may be required to redeem your shares and close your account. If your account is closed for this reason, your shares will be redeemed at the NAV next calculated after your account is closed, and you will bear any risk of loss.

Guggenheim Investments provides accounts for U.S. citizens and resident aliens. We will not open a new account for any non-resident aliens (natural person or entity). If you are unsure of your status please consult your tax adviser. Non-resident aliens may hold shares of the Funds through a financial intermediary, subject to that financial intermediary’s requirements.

Customer identification and verification is part of the Funds’ overall obligation to deter money laundering under applicable law. The Funds have adopted an anti-money laundering compliance program designed to prevent the Funds from being used for money laundering or the financing of terrorist activities. In this regard, the Funds reserve the right to (i) refuse, cancel or rescind any purchase or exchange order, (ii) freeze any account and/or suspend account services or (iii) involuntarily close your account in cases of threatening conduct or suspected fraudulent or illegal activity. These actions will be taken when, in the sole discretion of Fund management, they are deemed to be in the best interest of the Funds or in cases when the Funds are requested or compelled to do so by governmental or law enforcement authority. If your account is closed at the request of governmental or law enforcement authority, you may not receive proceeds of the redemption if the Fund is required to withhold such proceeds.

For information on what is required to make changes and/or additions to your account, and to obtain the appropriate forms, please visit the Guggenheim Investments website at www.rydex-sgi.com or call 800.820.0888 or 301.296.5100. If you own shares that are registered in your financial intermediary’s name, and you want to transfer the registration to another financial intermediary or want the shares registered in your name, then you should contact your financial intermediary for instructions on how to make this change.

Internet and telephone transactions are extremely convenient, but are not risk free. To ensure that your internet and telephone transactions are safe, secure, and as risk-free as possible, the Funds have instituted certain safeguards and procedures for determining the identity of website users (including the use of secure passwords and 128-bit encryption technology) and telephone callers and authenticity of instructions. As a result, neither the Funds nor their transfer agent will be responsible for any loss, liability, cost, or expense for following internet, telephone or wire instructions they reasonably believe to be genuine. If you or your intermediaries make exchange requests by telephone or internet, you will generally bear the risk of any loss. Neither the Funds nor their transfer agent are responsible for internet transactions that are not received.

During periods of unusually high market activity or other times, it may be difficult to reach Guggenheim Investments by telephone or access our internet site. Guggenheim Investments and its affiliates will not be liable for any losses resulting from a cause over which Guggenheim Investments or its affiliates do not have direct control, including but not limited to the failure of electronic or mechanical equipment or communication lines, telephone or other interconnect problems (e.g., if you are unable to access your online service provider), input errors on the internet, severe weather, facilities emergencies, earthquakes, floods and strikes or other labor problems. If you are not able to reach Guggenheim Investments by telephone, fax, or internet, consider sending written instructions.

You will receive statements and trade confirmations of your investment transactions. You may choose to receive your confirmations and/or statements either by mail or electronically (see “eDelivery Services” below).

eDelivery offers shareholders the convenience of receiving most communications (such as trade confirmations, statements, prospectuses and shareholder reports, etc.) from the Funds through the web via email notification. For more information on eDelivery, please visit the Guggenheim Investments website at www.rydex-sgi.com. The Funds reserve the right to discontinue your eDelivery service if two (2) or more e-mail notices are returned as undeliverable.

You may access information about the Funds and your Guggenheim Investments account anytime with the Guggenheim Investments Express Line. This automated line gives you telephone access to fund information including NAVs, daily factors, fund assets (fund assets information is available for most funds) and distributions as well as balance and history information on your Guggenheim Investments account.

Guggenheim Investments may charge the following administrative fees on accounts held directly through the Funds’ transfer agent for services associated with the following:

Guggenheim Investments reserves the right to change any of these fees or add additional service fees at any time.

An annual maintenance fee of $15 will be charged on the following retirement plans: IRA, SEP, Roth IRA, 403(b), Simple, Coverdell-ESA and Guggenheim Investments prototype money purchase plan and profit sharing plan accounts. You may pay the annual fee at any time during the calendar year by sending Guggenheim Investments a check. If the annual maintenance fee is not paid separately prior to December, it will be deducted automatically from your account.

An account closing fee of $15 will be charged upon liquidation of the following retirement accounts: IRA, SEP, Roth IRA, 403(b), Simple and Coverdell-ESA. This fee will be deducted from the proceeds of your redemption.

Guggenheim Investments will waive the annual maintenance fee if a liquidation fee is being charged. Guggenheim Investments also may waive the annual maintenance fee and any applicable account closing fee for certain 403(b) retirement plan accounts. For more information about the applicability of these fees, please contact Guggenheim Investments Client Services at 800.820.0888.

Frequent Trading Policy. Because the Funds (other than the Alternatives Funds and Asset Allocation Funds) are designed and operated to accommodate frequent trading by shareholders and, unlike most mutual funds, offer unlimited exchange privileges with no minimum holding periods or transaction fees, the Funds’ Board of Trustees has not adopted policies and procedures designed to prevent market timing or to monitor for frequent purchases and redemptions of Fund shares. A significant portion of the assets of the Funds come from investors who take part in certain strategic and tactical asset allocation programs. The Funds anticipate that investors who take part in these programs may frequently redeem or exchange shares of the Funds, which may cause the Funds to experience high portfolio turnover. Higher portfolio turnover may result in the Funds paying higher levels of transaction costs and generating greater tax liabilities for shareholders. In addition, large movements of assets into and out of the Funds may negatively impact the Funds’ ability to achieve their respective investment objectives.

The Alternatives Funds and Asset Allocation Funds are not suitable for purchase by active investors. The Funds are intended for long-term investment purposes only and discourage shareholders from engaging in “market timing” or other types of excessive short-term trading. This frequent trading into and out of the Funds may present risks to the Funds’ long-term shareholders, all of

which could adversely affect shareholder returns. The risks posed by frequent trading include interfering with the efficient implementation of the Funds’ investment strategies, triggering the recognition of taxable gains and losses on the sale of Fund investments, requiring the Funds to maintain higher cash balances to meet redemption requests, and experiencing increased transaction costs. The Funds do not accommodate frequent purchases and redemptions. Consequently, the Board of Trustees has adopted policies and procedures designed to prevent frequent purchases and redemptions of shares of the Funds.

For purposes of applying the Funds’ policies, the Advisor may consider the trading history of accounts under common ownership or control. In addition, the Funds reserve the right to reject any purchase request by any investor or group of investors for any reason without prior notice, including, in particular, if the Advisor reasonably believes that the trading activity would be harmful or disruptive to the Funds. Although these policies are designed to deter frequent trading, none of these measures alone nor all of them taken together eliminate the possibility that frequent trading in the Funds will occur, particularly with respect to trades placed by shareholders that invest in the Funds through omnibus accounts maintained by brokers, retirement plan accounts and other financial intermediaries. The Funds’ access to information about individual shareholder transactions made through such omnibus arrangements is often unavailable or severely limited. As a result, the Funds cannot assure that their policies will be enforced with regard to those Fund shares held through such omnibus arrangements (which may represent a majority of Fund shares), and as a result frequent trading could adversely affect the Funds and their long-term shareholders as discussed above.

The Funds reserve the right to close your account in cases of suspected fraudulent or illegal activity in accordance with applicable law. This action may be taken when, in the sole discretion of Fund management, it is deemed to be in the best interest of the Funds or in cases where the Funds are requested or compelled to do so by applicable law. If your account is closed at the request of governmental or law enforcement authority or pursuant to applicable law, you may not receive proceeds of the redemption if the Funds are required to withhold such proceeds.

The Funds have adopted a Distribution and Shareholder Services Plan pursuant to Rule 12b-1 under the 1940 Act with respect to Advisor Class Shares that allows the Funds to pay distribution and services fees to the Distributor and other firms that provide distribution or shareholder services (“Service Providers”). If a Service Provider provides distribution services, the Funds will pay distribution fees to the Distributor at an annual rate not to exceed 0.25% of average daily net assets. If a Service Provider provides shareholder services, the Funds will pay service fees to the Distributor at an annual rate not to exceed 0.25% of the average daily net assets of a Fund. The Distributor will, in turn, pay the Service Provider for the services it provides. Because these Funds pay these fees out of assets on an ongoing basis, over time these fees may cost you more than other types of sales charges.

The Funds have adopted a Distribution Plan pursuant to Rule 12b-1 under the 1940 Act with respect to H-Class Shares that allows each Fund to pay distribution fees to the Distributor and other Service Providers that provide distribution-related services at an annual rate not to exceed 0.25% of average daily net assets. The Funds also have adopted a Shareholder Services Plan that allows the Funds to pay Service Providers providing shareholder services a shareholder services fee at an annual rate not to exceed 0.25% of the average daily net assets of each Fund. Because the Funds pay these fees out of assets on an ongoing basis, over time these fees may cost you more than other types of sales charges and will increase the cost of your investment.

The Asset Allocation Funds have adopted a Distribution Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 with respect to H-Class Shares that allows each Fund to pay distribution fees to the Distributor and other Service Providers at an annual rate not to exceed 0.25% of average daily net assets, but generally do not pay these fees to the Distributor. Instead, the affiliated underlying funds have adopted a Distribution Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 applicable to A-Class Shares, in which the Funds invest, that allows each affiliated underlying fund to pay distribution fees to the Distributor and other Service Providers. The affiliated underlying funds will pay distribution fees to the Distributor at an annual rate not to exceed 0.25% of average daily net assets of A-Class Shares. If a Service Provider provides distribution services, the Distributor generally will, in turn, pay the Service Provider for the services it provides at an annual rate not to exceed 0.25% of the average daily net assets of A-Class Shares of the affiliated underlying funds. Because the affiliated underlying funds pay these fees out of assets on an ongoing basis, over time these fees may cost the Funds more than other types of sales charges and will increase the cost of your investment.

The Advisor, at its expense, may provide compensation to financial intermediaries for the sale of Fund shares. Such payments, commonly referred to as “revenue sharing,” do not increase Fund expenses and are not reflected in the fees and expenses shown in the “Fees and Expenses of the Fund” tables in this Prospectus. These payments may be made, at the discretion of the Advisor, to certain dealers who have sold shares of the Funds. The level of payments made to dealers will generally vary, but may be significant. The Advisor determines the extent of such payments in its sole discretion in response to requests from dealer firms, based on factors it deems relevant, such as the dealer’s sales, assets, share class utilized and the quality of the dealer’s relationship with the Advisor. The Advisor periodically determines the advisability of continuing these payments. The Advisor also may pay expenses associated with meetings conducted by dealers that facilitate educating financial advisers and shareholders about the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your sales person to recommend the Funds over another investment. Shareholders should inquire of an intermediary how the intermediary will be compensated for investments made in the Funds.

Income dividends, if any, are paid at least annually by each of the Funds, except the Government Long Bond 1.2x Strategy Fund and U.S. Government Money Market Fund, which declare dividends daily and pay them monthly or upon redemption. If you own Fund shares on a Fund’s record date, you will be entitled to receive the dividend. The Funds may declare and pay dividends on the same date. Each Fund makes distributions of capital gains, if any, at least annually. Each Fund, however, may declare a special capital gains distribution if the Board of Trustees believes that such a distribution would be in the best interest of the shareholders of the Fund.

Dividends and distributions will be paid in the form of additional Fund shares unless you have elected to receive payment in cash. If you did not elect to receive cash payments of dividends and distributions on your application, you must notify the Funds in writing to change your election prior to the date of the next distribution. Your election will become effective for dividends paid after the Funds receive your written notice. To cancel your election, simply send written notice to the Funds. Dividends and distributions with values of $25 or less may be automatically reinvested.

The following is a summary of some important tax issues that affect the Funds and their shareholders. The summary is based on current tax laws, which may be changed by legislative, judicial or administrative action. You should not consider this summary to be a detailed explanation of the tax treatment of the Funds, or the tax consequences of an investment in the Funds. More information about taxes is located in the SAI. You are urged to consult your tax adviser regarding specific questions as to federal, state and local income taxes.

Each Fund is treated as a separate entity for federal tax purposes, and intends to qualify for the special tax treatment afforded to regulated investment companies. As long as each Fund qualifies as a regulated investment company, the Fund pays no federal income tax on the earnings it timely distributes to shareholders.

One of the requirements for qualification as a regulated investment company under Subchapter M of the Internal Revenue Code is that each Fund derive at least 90% of its gross income for each taxable year from dividends, interest, payments with respect to certain securities loans, and gains from the sale or other disposition of stock, securities or foreign currencies, or other income derived with respect to its business of investing in such stock, securities or currencies, and net income derived from an interest in qualified publicly traded partnerships (“Qualifying Income”).

Certain ETNs, ETFs, and underlying funds in which a Fund may invest may not produce Qualifying Income for purposes of the 90% test described above, which must be met in order for a Fund to maintain its status as a regulated investment company under Subchapter M of the Internal Revenue Code. The Funds intend to monitor such investments to ensure that any non-qualifying income does not exceed permissible limits, but a Fund may not be able to accurately predict the non-qualifying income from these investments, which could cause a Fund to inadvertently fail to qualify as a regulated investment company.

If a Fund were to fail to qualify as a regulated investment company in any year, the Fund would be subject to federal income tax on its net income and capital gains at regular corporate income tax rates (without a deduction for distributions to shareholders). When distributed, that income would also be taxable to shareholders as an ordinary dividend to the extent attributable to the Fund’s earnings and profits. In addition, a Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company.

Each sale, exchange, or redemption of Fund shares may be a taxable event to you. For tax purposes, an exchange of Fund shares for shares of a different fund is treated the same as a sale. As noted above, certain shareholders also may be subject to the 3.8% Medicare contribution tax on capital gains realized on the sale or exchange of shares. You should consider the tax consequences of any redemption or exchange before making such a request, especially with respect to redemptions if you invest in the Funds through a tax-qualified retirement plan.

The Funds are not liable for any income or franchise tax in Delaware as long as they qualify as regulated investment companies for federal income tax purposes. In addition to federal taxes, distributions by the Funds and ownership of Fund shares may be subject to state and local taxes. You should consult your tax adviser regarding how state and local tax laws affect your investment in Fund shares.

Legislation passed by Congress in 2008 requires the Funds (or their administrative agent) to report to the IRS and furnish to Fund shareholders the cost basis information for covered shares (those generally purchased on or after January 1, 2012, and sold on or after that date). In addition to the present law requirement to report the gross proceeds from the sale of Fund shares, the Funds also will be required to report the cost basis information for such covered shares and indicate whether these shares had a short-term or long-term holding period. For each sale of Fund covered shares, the Funds will permit Fund shareholders to elect from among several IRS-accepted cost basis methods, including average cost, FIFO, LIFO and HIFO. In the absence of an election, the Funds will use a default cost basis method which is the average cost method. The cost basis method elected by a Fund shareholder (or the cost basis method applied by default) for each sale of Fund shares may not be changed after the close of business on trade date of each such sale of Fund shares. Fund shareholders should consult with their tax advisers to determine the best IRS-accepted cost basis method for their tax situation and to obtain more information about how the new cost basis reporting law applies to them. These new reporting requirements only apply to require the reporting of the gross proceeds from the sale of Fund shares acquired and sold after December 31, 2011.

The financial highlights tables are intended to help you understand each Fund’s financial performance for the past 5 years (or, if shorter, the period of operations of that Fund’s shares). Certain information reflects financial results for a single share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in a Fund (assuming reinvestment of all dividends and distributions). The information provided below has been audited by Ernst & Young LLP, an independent registered public accounting firm, whose reports, along with the financial statements and related notes, appear in the Funds’ 2012 Annual Reports. The 2012 Annual Reports are available by telephoning the transfer agent at 800.820.0888 or 301.296.5100.

This table is presented to show selected data for a share outstanding throughout each period and to assist shareholders in evaluating a Fund’s performance for the periods presented.
