This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may be required to pay a commission to your financial intermediary for effecting transactions in a class of shares of the Fund without any initial sales charge, contingent deferred sales charge, or other asset-based fee for sales or distribution. These commissions are not reflected in the fee and expense table or expense example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in the Family of Funds, as defined on page 147 of the Fund’s prospectus. This amount may vary depending on the Guggenheim Fund in which you invest. More information about these and other discounts is available from your financial professional and in the “Sales Charges-Class A Shares” section on page 101 of the Fund’s prospectus and the “How to Purchase Shares” section on page 80 of the Fund’s Statement of Additional Information. Different intermediaries and financial professionals may impose different sales charges or offer different sales charge waivers or discounts. These variations are described in Appendix A to the Fund’s prospectus (Intermediary-Specific Sales Charge Waivers and Discounts).

PORTFOLIO TURNOVER

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 126% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal market conditions, in long and short positions of domestic equity and equity-related securities (including swaps and other derivative investments giving long or short exposure to domestic equity securities).

The Investment Manager uses a proprietary evaluation process to generate an expected return for individual stocks that considers market risk factors generally and risks specific to the companies in which the Fund invests. Market risk factors include, among other factors, company size, enterprise value, and sector. The Investment Manager seeks to construct portfolios of equity-related investments that maintain long positions in instruments that provide exposure to risk factors that the Investment Manager considers to be undervalued by the equity markets and sells short instruments that provide exposure to risk factors that the Investment Manager considers to be overvalued by the equity markets. The process uses fundamentally-based, forward-looking forecasts of equity cash flows to generate return expectations for individual stocks. Then, the expected returns for the universe of stocks is further evaluated using quantitative techniques to estimate the market’s implied valuation of broad market risk factors as well as the company-specific risks. Finally, a portfolio is constructed within guidelines that buys long the stocks (or derivatives that give exposure to stocks) that give the portfolio both the broad risk characteristics and company-specific risks that are perceived to be undervalued and sells short stocks (or derivatives that give exposure to stocks) for which those characteristics are perceived to be overpriced. “Alpha” in the Fund’s name refers to the potential for the Fund’s portfolio to achieve returns that are favorable relative to the amount of risk taken. Of course, there is no guarantee that the Fund will achieve its objective of long-term growth of capital, and an investment in the Fund involves significant risk.

The Fund will ordinarily hold simultaneous long and short positions in equity securities or securities markets that provide exposure up to a level equal to 150% of the Fund’s net assets for both the long and short positions. That level of exposure is obtained through derivatives, including swap agreements (which include, but are not limited to, total return swap agreements). The Investment Manager intends to maintain a low overall net exposure (the difference between the notional value of long positions and the notional value of short positions) for the portfolio, typically varying between 50% net long and 30% net short to seek to maintain low correlation to traditional equity markets, lower than market volatility and seek to provide consistent absolute return. The overall net exposure will change as market opportunities change, and may, based on the Investment Manager’s view of current market conditions, be outside this range.

The Fund may invest in domestic equity securities, including small-, mid-, and large-capitalization securities. The Fund also may invest in derivative instruments, including swaps on selected baskets of equity securities, to enable the Fund to pursue its investment objective without investing directly in the securities of companies to which the Fund is seeking exposure. The Fund may also invest in derivatives, such as options and futures contracts, to hedge or gain leveraged exposure to a particular sector, industry, market risk factor, or company and/or to obtain or replicate market exposure depending on market conditions. The Fund will often invest in instruments traded in the over the-counter (“OTC”) market, which generally provides for less transparency than exchange-traded instruments. The Fund also may enter into long positions or short sales of broad-based stock indices for hedging purposes in an effort to reduce the Fund’s risk or volatility through, among other instruments, exchange-traded funds ("ETFs") and closed-end funds. The use of derivatives may create a leveraging effect on the Fund which will force the Fund to take offsetting positions or earmark or segregate assets to be used as collateral. The Fund actively trades its investments, which can result in significant fluctuations in the Fund's portfolio turnover rate.

While the Fund anticipates investing in these securities and instruments to seek to achieve its investment objective, the extent of the Fund’s investment in these securities and 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 instruments, 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 adverse or unstable market conditions or abnormal circumstances, the Fund could invest some or all of its assets in cash, derivatives, fixed-income instruments, government bonds, money market instruments, repurchase agreements or securities of other investment companies. The Fund may be unable to pursue or achieve its investment objective during that time and temporary investments could reduce the benefit from any upswing in the market.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

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

Counterparty Credit Risk—The Fund makes investments in financial instruments and OTC-traded derivatives involving counterparties to gain exposure to a particular group of securities, index, asset class or other reference asset without actually purchasing those securities or investments, to hedge a position, or for other investment purposes. Through these investments and related arrangements (e.g., prime brokerage or securities lending arrangements or derivatives transactions), the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments or otherwise to meet its contractual obligations. If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease.

Credit Risk—The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a derivatives transaction or other transaction is unable or unwilling, or perceived to be unable or unwilling, to pay interest or repay principal on time or defaults. The issuer, guarantor or counterparty could also suffer a rapid decrease in credit quality rating, which would adversely affect the volatility of the value and liquidity of the instrument. Credit ratings may not be an accurate assessment of liquidity or credit risk.

Derivatives Risk—Derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation and legal restrictions. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The Fund’s use of derivatives to obtain short exposure may result in greater volatility of the Fund's net asset value ("NAV") per share. If the Investment Manager is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. In addition, the Fund’s use of derivatives may cause the Fund to realize higher amounts of short term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened counterparty credit, liquidity and valuation risks. Certain risks also are specific to the derivatives in which the Fund invests.

Futures Contracts Risk—Futures contracts are exchange-traded contracts that call for the future delivery of an asset at a certain price and date, or cash settlement of the terms of the contract. Risks of futures contracts may be caused by an imperfect correlation between movements in the price of the instruments and the price of the underlying assets. In addition, there is a risk that the Fund may not be able to enter into a closing transaction because of an illiquid market. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Investment Manager, thus limiting the ability to implement the Fund’s strategies. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s net asset value. Futures are also subject to leverage risks and to liquidity risk.

Options Risk—Options or options on futures contracts give the holder of the option the right, but not the obligation, to buy (or to sell) a position in a security or in a contract to the writer of the option, at a certain price. Options are subject to correlation risk because there may be an imperfect correlation between the options and securities markets for underlying instruments that could cause a given transaction to fail to achieve its objectives. The successful use of options depends on the Investment Manager’s ability to predict correctly future price fluctuations and the degree of correlation between the markets for options and the underlying instruments. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Investment Manager, thus limiting the ability to implement the Fund’s strategies. Options are also particularly subject to leverage risk and can be subject to liquidity risk.

Swap Agreements Risk—Swap agreements are contracts among the Fund and a counterparty to exchange the return of the pre-determined underlying investment (such as the rate of return of the underlying index). Swap agreements may be negotiated bilaterally and traded OTC between two parties or, in some instances, must be exchange-traded through a futures commission merchant and/or cleared through a clearinghouse that serves as a central counterparty. Risks associated with the use of swap agreements are different from those associated with ordinary portfolio securities transactions, due in part to the fact they could be considered illiquid and many swaps trade on the OTC market. Swaps are particularly subject to counterparty credit, correlation, valuation, liquidity and leveraging risks. Certain standardized swaps are subject to mandatory exchange trading and central clearing. Exchange trading and central clearing are intended to reduce counterparty credit risk and increase liquidity but exchange trading and central clearing do not make swap transactions risk-free. Additionally, applicable regulators have adopted rules imposing certain margin requirements, including minimums, on OTC swaps, which may result in the Fund and its counterparties posting higher margin amounts for OTC swaps, which could increase the cost of swap transactions to the Fund and impose added operational complexity.

Equity Securities Risk—Equity securities include common stocks and other equity and equity-related securities (and securities convertible into stocks). The prices of equity securities generally fluctuate in value more than fixed-income investments, may rise or fall rapidly or unpredictably and may reflect real or perceived changes in the issuing company’s financial condition and changes in the overall market or economy. A decline in the value of equity securities held by the Fund will adversely affect the value of your investment in the Fund. Common stocks generally represent the riskiest investment in a company and dividend payments (if declared) to preferred stockholders generally rank junior to payments due to a company’s debtholders. The Fund may lose a substantial part, or even all, of its investment in a company’s stock.

Interest Rate Risk—Fixed-income and other debt instruments are subject to the possibility that interest rates could change. Changes in interest rates may adversely affect the Fund’s investments in these instruments, such as the value or liquidity of, and income generated by, the investments. Interest rates may change as a result of a variety of factors, and the change may be sudden and significant, with unpredictable impacts on the financial markets and the Fund’s investments. Fixed-income and other debt instruments with longer durations are more sensitive to changes in interest rates and, thus, subject to more volatility than similar instruments with shorter durations. Generally, when interest rates increase, the values of fixed-income and other debt instruments decline and when interest rates decrease, the values of fixed-income and other debt instruments rise. During periods of rising interest rates, because changes in interest rates on adjustable rate securities may lag behind changes in market rates, the value of such securities may decline until their interest rates reset to market rates. During periods of declining interest rates, because the interest rates on adjustable rate securities generally reset downward, their market value is unlikely to rise to the same extent as the value of comparable fixed rate securities. The risks associated with rising interest rates are heightened given the recent low interest rate environment.

Investments by Investing Funds and Other Large Shareholders—The Fund is subject to the risk that a large investor, including certain other investment companies, purchases or redeems a large percentage of Fund shares at any time. As a result, the Fund's performance or liquidity may be adversely affected as the Fund tends to hold a large proportion of its assets in cash and may have to sell investments at disadvantageous times or prices to meet large redemption requests.

Investment in Investment Vehicles Risk—Investing in other investment vehicles, including ETFs, closed-end funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles’ expenses, which will reduce the Fund’s performance. In addition, investments in an ETF are subject to, among other risks, the risk that the ETF's shares may trade at a discount or premium relative to the net asset value of the shares and the listing exchange may halt trading of the ETF's shares.

Large-Capitalization Securities Risk—The Fund is subject to the risk that large-capitalization securities may underperform other segments of the equity market or the equity market as a whole. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and may not be able to attain the high growth rate of smaller companies, especially during extended periods of economic expansion.

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

Liquidity and Valuation Risk—It may be difficult for the Fund to purchase and sell particular investments within a reasonable time at a fair price, or the price at which it has been valued by the Investment Manager for purposes of the Fund’s net asset value, causing the Fund to be less liquid and unable to realize what the Investment Manager believes should be the price of the investment. Valuation of portfolio investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks may be heightened for fixed-income instruments because of the near historically low interest rate environment as of the date of this prospectus.

Management Risk—The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns, causing the Fund to fail to meet its investment objective or underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active and frequent trading that can accompany active management, also called “high turnover,” may have a negative impact on performance. Active and frequent trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active and frequent trading may also result in adverse tax consequences.

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

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

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

Regulatory and Legal Risk—U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund (such as regulations related to investments in derivatives and other transactions). These regulations and laws impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.

Repurchase Agreements and Reverse Repurchase Agreements Risk—In the event of the insolvency of the counterparty to a repurchase agreement or reverse repurchase agreement, recovery of the repurchase price owed to the Fund or, in the case of a reverse repurchase agreement, the securities sold by the Fund, may be delayed. Because reverse repurchase agreements may be considered to be the practical equivalent of borrowing funds, they constitute a form of leverage. If the Fund reinvests the proceeds of a reverse repurchase agreement at a rate lower than the cost of the agreement, entering into the agreement will lower the Fund’s yield.

Short Sale and Short Exposure Risk—Short selling a security involves selling a borrowed security with the expectation that the value of that security will decline, so that the security may be purchased at a lower price when returning the borrowed security. A short exposure through a derivative exposes the Fund to counterparty credit risk and leverage risk. The risk for loss on a short sale or other short exposure is greater than a direct investment in the security itself because the price of the borrowed security may rise, thereby increasing the price at which the security must be purchased. The risk of loss through a short sale or other short exposure may in some cases be theoretically unlimited. 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 securities may underperform other segments of the equity market or the equity market as a whole. Securities of small-capitalization companies may be more speculative, volatile and less liquid than securities of larger companies. Small-capitalization companies tend to have inexperienced management as well as limited product and market diversification and financial resources, and may be more vulnerable to adverse developments than mid- or large-capitalization companies.

U.S. Government Securities Risk—U.S. government securities may or may not be backed by the full faith and credit of the U.S. government. U.S. government securities are subject to the risks associated with fixed-income and debt securities, particularly interest rate risk and credit risk.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in equity securities, which include common stocks, rights, options, warrants, convertible debt securities of both U.S. and U.S. dollar-denominated foreign issuers, and American Depositary Receipts (“ADRs”), of companies that, when purchased, have market capitalizations that are usually within the range of companies in the Russell 1000® Value Index. Although a universal definition of large market capitalization companies does not exist, the Fund generally defines large market capitalization companies as those whose market capitalization is similar to the market capitalization of companies in the Russell 1000® Value Index, which is an unmanaged index measuring the performance of the large cap value segment of the U.S. equity universe and which includes companies with lower price-to-book ratios and lower expected growth values. As of December 31, 2019, the Russell 1000® Value Index consisted of securities of companies with market capitalizations that ranged from $839.7 million to $554.4 billion.

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

The Fund may invest a portion of its assets in derivatives, including options and futures contracts. These instruments are used to hedge the Fund’s portfolio, to maintain exposure to the equity markets, or to increase returns. The Fund may invest in a variety of investment vehicles, including those that seek to track the composition and performance of a specific index, such as exchange-traded funds (“ETFs”) and other mutual funds. The Fund may use these investments as a way of managing its cash position or to gain exposure to the equity markets or a particular sector of the equity markets. These investments may be more liquid than investing directly in individual issuers.

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

The Fund may invest in a limited number of sectors or industries.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Convertible Securities Risk—Convertible securities may be subordinate to other securities. The total return for a convertible security depends, in part, upon the performance of the underlying security into which it can be converted. The value of convertible securities tends to decline as interest rates increase. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality.

Counterparty Credit Risk—The Fund makes investments in financial instruments and over-the-counter ("OTC")-traded derivatives involving counterparties to gain exposure to a particular group of securities, index, asset class or other reference asset without actually purchasing those securities or investments, to hedge a position, or for other investment purposes. Through these investments and related arrangements (e.g., prime brokerage or securities lending arrangements or derivatives transactions), the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments or otherwise to meet its contractual obligations. If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease.

Depositary Receipt Risk—The Fund may hold the securities of non-U.S. companies in the form of depositary receipts. The underlying securities of the depositary receipts in the Fund’s portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Fund’s portfolio. In addition, the value of the securities underlying the depositary receipts may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.

Derivatives Risk—Derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation and legal restrictions. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in leverage, which may cause the Fund to be more volatile and riskier than if it had not been leveraged. If the Investment Manager is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. In addition, the Fund’s use of derivatives may cause the Fund to realize higher amounts of short term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened counterparty credit, liquidity and valuation risks.

Investment in Investment Vehicles Risk—Investing in other investment vehicles, including ETFs, closed-end funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles’ expenses, which will reduce the Fund’s performance. In addition, investments in an ETF are subject to, among other risks, the risk that the ETF's shares may trade at a discount or premium relative to the net asset value ("NAV") of the shares and the listing exchange may halt trading of the ETF's shares.

Real Estate Investments Risk—The Fund may invest in securities of real estate companies and companies related to the real estate industry, which are subject to the same risks as direct investments in real estate. These risks include, among others: changes in national, state or local real estate conditions; obsolescence of properties; changes in the availability, cost and terms of mortgage funds; changes in the real estate values and interest rates; and the generation of sufficient income. Real estate companies tend to have micro-, small- or mid-capitalization, making their securities more volatile and less liquid than those of companies with larger-capitalizations. Real estate companies may use leverage (and some may be highly leveraged), which increases investment risk and the risks normally associated with debt financing and could adversely affect a real estate company’s operations and market value in periods of rising interest rates. These risks are especially applicable in conditions of declining real estate values, such as those experienced during 2007 through 2009.

REIT Risk—In addition to the risks pertaining to real estate investments more generally, real estate investment trusts ("REITs") are subject to additional risks. The value of a REIT can depend on the structure of and cash flow generated by the REIT. REITs whose investments are concentrated in a limited number or type of properties, investments or narrow geographic area are subject to the risks affecting those properties or areas to a greater extent than a REIT with less concentrated investments. REITs are also subject to certain provisions under federal tax law. In addition, REITs may have expenses, including advisory and administration expenses, and the Fund and its shareholders will incur its pro rata share of the underlying expenses.

Sector Emphasis Risk—If the Fund invests a significant amount of its assets in any one sector, the Fund’s performance

will depend to a greater extent on the overall condition of the sector and there is increased risk that the Fund will

lose value if conditions adversely affect that sector. The prices of securities of issuers in a particular sector may be

more susceptible to fluctuations as a result of changes in economic or business conditions, government regulations,

availability of basic resources or supplies, or other events that affect that industry or sector more than securities of

issuers in other sectors. To the extent the Fund is heavily invested in a particular sector, the Fund’s share price may

be more volatile than the value of shares of a mutual fund that invests in a broader range of sectors.

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.

Risk Lose Money [Text]

rr_RiskLoseMoney

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

Risk Not Insured Depository Institution [Text]

rr_RiskNotInsuredDepositoryInstitution

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any governmental agency.

Strategy [Heading]

rr_StrategyHeading

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will employ a fundamental long-short real estate strategy that seeks to neutralize exposure to general stock market risk and volatility by taking both long and short positions in real estate investments. The Fund’s investment approach seeks to provide positive returns that are neutral with regard to other major asset classes and volatility, but the Fund’s returns may be negative during certain periods.

The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in: (i) long and short equity securities of issuers primarily engaged in the real estate industry, such as real estate investment trusts (“REITs”); and (ii) equity-like securities, including individual securities, exchange-traded funds (“ETFs”) and derivatives, giving long and short exposure to (i.e., economic characteristics similar to) issuers primarily engaged in the real estate industry.

The Fund will consider an issuer to be primarily engaged in the real estate industry if: (i) at least 50% of its assets, income, sales or profits are committed to, or derived from, the ownership, construction, management, financing, leasing, brokering, or sale of residential, or commercial real estate, or the provision of products and services related to the real estate industry, such as building supply manufacturers, mortgage lenders, or mortgage servicing companies or (ii) a widely recognized industry classification system provider has given the company an industry or sector classification consistent with the real estate industry.

Equity securities in which the Fund may invest include common stocks, REITs and other investment vehicles primarily engaged in the real estate industry, ETFs, and American Depositary Receipts ("ADRs"). The Fund may also invest in exchange-traded notes ("ETNs") giving exposure to real estate markets. The Fund may take a long position by buying a security that Guggenheim Partners Investment Management, LLC, also known as Guggenheim Investments (the "Investment Manager"), believes will appreciate, or it may sell a security short by first borrowing it from a third party with the intention to sell it later at a market price. The Fund will usually obtain exposure to short positions by entering into derivative instruments. Short positions may be used either to hedge long positions or to seek positive returns where the Investment Manager believes the security will depreciate.

The Investment Manager will make investment decisions based primarily on a relative value fundamental framework. These investment decisions will be guided by a top-down approach to allocating the Fund’s assets among geographic regions and property sectors. The Investment Manager will then select individual securities using a bottom-up approach, focused primarily on a relative value-oriented process that reflects the macro-level investment themes and a due diligence process that includes, among other analytical components, an assessment of issuer-specific factors such as management acumen and strategic direction.

The Fund may dynamically adjust its level of long and short exposure to the real estate markets over time based on macroeconomic, industry-specific, and other factors. The Fund pursues a strategy commonly referred to as “market neutral” because it is intended to maintain long and short positions that offset one another. As a result, the Fund’s net market exposure will normally approximate zero. The Fund’s long-short strategy is designed to reduce the Fund’s overall exposure to general stock market movements and produce returns that are uncorrelated to other major asset classes. The Fund may reinvest the proceeds of its short sales by taking additional long positions.

To enhance the Fund’s exposure to real estate markets and to seek to increase the Fund’s returns, at the discretion of the Investment Manager, the Fund’s long and short positions in equities may be combined with investments in derivatives. The derivatives in which the Fund invests include, among other derivatives, swap agreements (some of these instruments may be traded in the over-the-counter market). These investments will be used to obtain the Fund's short exposure and may also be used to hedge the Fund’s portfolio, to maintain long exposure to the equity markets, to increase returns, to generate income, or to seek to manage volatility of the portfolio.

The Fund may also invest a substantial portion of its assets, including proceeds of its short sales, in investment companies advised by the Investment Manager, or an affiliate of the Investment Manager, that invest in short-term fixed-income or floating rate securities, such as high yield, high risk debt securities (also known as “junk bonds”), asset-backed securities and commercial paper. Such investments will expose the Fund to the risks of these asset categories, such as credit and interest rate risk.

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 Fund will concentrate its investments in the real estate industry (i.e., invest more than 25% of its total assets in securities of issuers considered to be primarily engaged in the real estate industry).

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Concentration Risk—Real estate companies may lack diversification due to ownership of a limited number of properties and concentration in a particular geographic region or property type. By concentrating in the real estate industry, the Fund is subject to the risks specifically affecting that industry more than a fund that invests across a variety of industries.

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 investments, changes in the applicable interest rates, changes in the issuer’s credit rating and economic, legal, political or geographic events that affect the referenced investments. 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 (which includes the risk that the issuer may fail).

Investment in Investment Vehicles Risk—Investing in other investment vehicles, including ETFs, closed-end funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles’ expenses, which will reduce the Fund's performance. In addition, investments in an ETF are subject to, among other risks, the risk that the ETF's shares may trade at a discount or premium relative to the net asset value of the shares and the listing exchange may halt trading of the ETF's shares.

The Fund’s investments in investment companies advised by the Investment Manager, or an affiliate of the Investment Manager, that invest in short-term fixed-income or floating rate securities expose the Fund to credit and interest rate risk. In addition, these investments expose the Fund to the risks associated with asset-backed securities, collateralized loan and debt obligations, commercial paper and high yield and unrated securities.

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

There is no guarantee that the Fund will be able to neutralize or limit exposure to general stock market risk. The Fund’s use of short sales in combination with its long positions in an attempt to limit direct market exposure and improve performance may be unsuccessful and may result in greater losses or lower positive returns than if the Fund held only long positions. During times when the overall market is performing strongly, the Fund may underperform the market because the Fund’s short positions may be more likely to lose money than during other market conditions.

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

REIT Risk—In addition to the risks pertaining to real estate investments more generally, REITs are subject to additional risks. The value of a REIT can depend on the structure of and cash flow generated by the REIT. REITs whose investments are concentrated in a limited number or type of properties, investments or narrow geographic area are subject to the risks affecting those properties or areas to a greater extent than a REIT with less concentrated investments. REITs are also subject to certain provisions under federal tax law. In addition, REITs may have expenses, including advisory and administration expenses, and the Fund and its shareholders will incur its pro rata share of the underlying expenses.

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in: (i) long and short equity securities of issuers primarily engaged in the real estate industry, such as real estate investment trusts (“REITs”); and (ii) equity-like securities, including individual securities, exchange-traded funds (“ETFs”) and derivatives, giving exposure to (i.e., economic characteristics similar to) issuers primarily engaged in the real estate industry. The Fund seeks to manage investment risk by taking both long and short positions in real estate investments by combining a traditional long-only REIT strategy sleeve and a market-neutral long/short strategy sleeve.

The Fund will consider an issuer to be primarily engaged in the real estate industry if: (i) at least 50% of its assets, income, sales or profits are committed to, or derived from, the ownership, construction, management, financing, leasing, brokering, or sale of residential or commercial real estate, or the provision of products and services related to the real estate industry, such as building supply manufacturers, mortgage lenders, or mortgage servicing companies or (ii) a widely recognized industry classification system provider has given the company an industry or sector classification consistent with the real estate industry.

Equity securities in which the Fund may invest include common stocks, REITs and other investment vehicles primarily engaged in the real estate industry, ETFs, exchange-traded notes (“ETNs”) giving exposure to real estate markets, and American Depositary Receipts (“ADRs”). The Fund may take a long position by buying a security that that Guggenheim Partners Investment Management, LLC, also known as Guggenheim Investments ("the Investment Manager"), believes will appreciate, or it may sell a security short by first borrowing it from a third party with the intention to sell it later at a market price. The Fund may also obtain exposure to long and short positions by entering into swap agreements (including, but not limited to, total return swap agreements). Short positions may be used either to hedge long positions or to seek positive returns where the Investment Manager believes the security will depreciate. The Investment Manager will make investment decisions based primarily on a fundamental relative value framework. These investment decisions will be guided by a top-down approach to allocating the Fund’s assets among geographic regions and property sectors. The Investment Manager will then select individual securities using a bottom-up approach, focused primarily on a relative value-oriented process that reflects the macro-level investment themes and a due diligence process that includes, among other analytical components, an assessment of issuer-specific factors such as management acumen and strategic direction.

The Fund may dynamically adjust its level of long and short exposure to the real estate markets by adjusting allocations between its long-only REIT strategy sleeve and market-neutral long/short strategy sleeve over time based on macroeconomic, industry-specific, and other factors. However, the Investment Manager expects the Fund’s net exposure over time will be long biased. The Fund may reinvest the proceeds of its short sales by taking additional long positions, or it may use leverage to maintain long positions in excess of 100% of net assets.

To enhance the Fund’s exposure to real estate markets and to seek to increase the Fund’s returns, at the discretion of the Investment Manager, the Fund’s long and short positions in equities may be combined with investments in derivatives, which may include, among other derivatives: swap agreements (including, among other types of swaps, total return swaps); options on securities, futures contracts, and stock indices; and stock index futures contracts (some of these instruments may be traded in the over-the-counter market). These investments may be used to hedge the Fund’s portfolio, to maintain exposure to the equity markets, to increase returns, to generate income, or to seek to manage volatility of the portfolio. The Fund intends to borrow from banks to take larger positions and to seek an enhanced return.

While the Fund will principally invest in securities listed, traded or dealt in the United States, it may also invest without limitation in securities listed, traded or dealt in other countries, including emerging markets countries. Such securities may be denominated in foreign currencies.

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Futures Contracts Risk—Futures contracts are exchange-traded contracts that call for the future delivery of an asset at a certain price and date, or cash settlement of the terms of the contract. Risks of futures contracts may be caused by an imperfect correlation between movements in the price of the instruments and the price of the underlying assets. In addition, there is a risk that the Fund may not be able to enter into a closing transaction because of an illiquid market. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Investment Manager, thus limiting the ability to implement the Fund’s strategies. Futures markets are highly volatile and the use of futures may increase the volatility of the Fund’s NAV. Futures are also subject to leverage risks and to liquidity risk.

Emerging Markets Risk—Investments in or exposure to emerging markets are generally subject to a greater level of those risks associated with investing in or being exposed to developed foreign markets, as emerging markets are considered to be less developed than developing countries. Furthermore, investments in or exposure to emerging markets are generally subject to additional risks, including the risks associated with trading in smaller markets, lower volumes of trading, and being subject to lower levels of government regulation and less extensive accounting, financial and other reporting requirements.

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

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

Expense Narrative [Text Block]

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may be required to pay a commission to your financial intermediary for effecting transactions in a class of shares of the Fund without any initial sales charge, contingent deferred sales charge, or other asset-based fee for sales or distribution. These commissions are not reflected in the fee and expense table or expense example below. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in the Family of Funds, as defined on page 146 of the Fund’s prospectus. This amount may vary depending on the Guggenheim Fund in which you invest. More information about these and other discounts is available from your financial professional and in the “Sales Charges-Class A Shares” section on page 100 of the Fund’s prospectus and the “How to Purchase Shares” section on page 90 of the Fund’s Statement of Additional Information. Different intermediaries and financial professionals may impose different sales charges or offer different sales charge waivers or discounts. These variations are described in Appendix A to the Fund’s prospectus (Intermediary-Specific Sales Charge Waivers and Discounts).

PRINCIPAL INVESTMENT STRATEGIES

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its assets (net assets, plus the amount of any borrowings for investment purposes) in a diversified portfolio of equity securities, which include common stocks, rights, options, warrants, convertible debt securities, and American Depositary Receipts (“ADRs”), that, when purchased, have market capitalizations that are usually within the range of companies in the Russell 2000® Value Index. Although a universal definition of small-capitalization companies does not exist, the Fund generally defines small-capitalization companies as those whose market capitalization is similar to the market capitalization of companies in the Russell 2000® Value Index, which is an unmanaged index measuring the performance of the small cap value segment of the U.S. equity universe and which includes companies with lower price-to-book ratios and lower forecasted growth values. As of December 31, 2019, the Russell 2000® Value Index consisted of securities of companies with market capitalizations that ranged from $24.5 million to $6.8 billion.

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

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

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

The Fund may invest in a limited number of sectors or industries.

Risk [Heading]

rr_RiskHeading

PRINCIPAL RISKS

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Derivatives Risk—Derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, liquidity, valuation and legal restrictions. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in leverage, which may case the Fund to be more volatile and riskier than if it had not been leveraged. If the Investment Manager is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. In addition, the Fund’s use of derivatives may cause the Fund to realize higher amounts of short term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened counterparty credit, liquidity and valuation risks.

Investment in Investment Vehicles Risk—Investing in other investment vehicles, including ETFs, closed-end funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles’ expenses, which will reduce the Fund’s performance. In addition, investments in an ETF are subject to, among other risks, the risk that the ETF's shares may trade at a discount or premium relative to the net asset value ("NAV") of the shares and the listing exchange may halt trading of the ETF's shares.

Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.
