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 28% of the average value of its portfolio.

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:10.02pt;font-weight:bold;">PRINCIPAL INVESTMENT STRATEGIES</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund 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 2500® Value Index. Although a universal definition of small- and mid-capitalization (i.e., SMid-capitalization) companies does not exist, the Fund generally defines SMid-capitalization companies as those whose market capitalization is similar to the market capitalization of companies in the Russell 2500® Value Index, which is an unmanaged index measuring the performance of securities of small-to-mid cap U.S. companies with greater-than-average value orientation. As of December 31, 2023, the Russell 2500® Value Index consisted of securities of companies with market capitalizations that ranged from approximately $16.8 million to $22.3 billion.In choosing securities, Security Investors, LLC, also known as Guggenheim Investments (the “Investment Manager”), primarily invests in value-oriented companies. Value-oriented companies are companies that appear to be undervalued relative to assets, earnings, growth potential or cash flows. The Investment Manager uses a blend of quantitative and fundamental analysis to identify securities that appear favorably priced and have the potential to appreciate in value. The Investment Manager regularly evaluates the metrics and data underlying the quantitative model and, from time to time, may make adjustments for a variety of reasons, including, without limitation, to account for changing market, financial or economic conditions.The Fund may invest a portion of its assets in derivatives, including options and futures contracts. These instruments are used to hedge the Fund’s portfolio, to maintain exposure to the equity markets or to increase returns.The Fund may invest in a variety of investment vehicles, including those that seek to track the composition and performance of a specific index, such as exchange-traded funds (“ETFs”) and other mutual funds. The Fund may use these investments as a way of managing its cash position or to gain exposure to the equity markets or a particular sector of the equity markets. These investments may be more liquid than investing directly in individual issuers. Certain investment vehicles’ securities and other securities in which the Fund may invest are restricted securities (consisting of securities originally issued in reliance on Rule 144A and Regulation S securities), which may be illiquid.The Fund 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.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.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	<span style="color:#000000;font-family:Arial;font-size:10.02pt;font-weight:bold;">PERFORMANCE INFORMATION</span>
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The following chart and table provide some indication of the risks of investing in the Fund. Because Class R6 shares had not commenced operations as of the date of this Prospectus, the following chart and table show the Fund’s Institutional Class share calendar year performance from year to year and average annual returns for the one, five and ten year or, if shorter, since inception periods, as applicable, for the Fund's Institutional Class shares compared to those of a broad measure of market performance. Class R6 shares and Institutional Class shares of the Fund would have substantially similar performance because they invest in the same portfolio of securities. However, the performance of Class R6 shares would be higher than Institutional Class shares to the extent Class R6 shares pay lower expenses than Institutional Class shares.On January 3, 2020, the Guggenheim SMid Cap Value Institutional Fund (formerly, the Guggenheim Mid Cap Value Institutional Fund), which also was an investment company registered under the Investment Company Act of 1940 and pursued the same investment objective and principal investment strategies as the Fund and was managed in the same manner, reorganized with and into Institutional Class shares of the Fund. The Fund has adopted the Guggenheim SMid Cap Value Institutional Fund's performance history with respect to its Institutional Class shares. Accordingly, the performance of the Institutional Class shares of the Fund shown below for the periods prior to January 3, 2020 is the performance of the Guggenheim SMid Cap Value Institutional Fund. The returns shown below for the Guggenheim SMid Cap Value Institutional Fund have not been restated to reflect the fees and expenses applicable to the Institutional Class shares of the Fund and could have been lower had such an adjustment been made.As with all mutual funds, past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available on the Fund’s website at www.guggenheiminvestments.com or by calling 800.820.0888.Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

R6 Shares | Guggenheim SMid Cap Value Fund | Risk Lose Money [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	The value of an investment in the Fund will fluctuate and is subject to investment risks, which means investors could lose money, including all or part of their investment in the Fund.
R6 Shares | Guggenheim SMid Cap Value Fund | Risk Not Insured Depository Institution [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any governmental agency.
R6 Shares | Guggenheim SMid Cap Value Fund | Convertible Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Convertible Securities Risk—Convertible securities may be subordinate to other securities. The total return for a convertible security depends, in part, upon the performance of the underlying security into which it can be converted. The value of convertible securities tends to decline as interest rates increase. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality.
R6 Shares | Guggenheim SMid Cap Value Fund | Counterparty Credit Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Counterparty Credit Risk—The Fund makes investments in financial instruments and OTC-traded derivatives involving counterparties to gain exposure to a particular group of securities, index, asset class or other reference asset without actually purchasing those securities or investments, to hedge a position, or for other investment purposes. Through these investments and related arrangements (e.g., prime brokerage or securities lending arrangements or derivatives transactions), the Fund is exposed to credit risks that the counterparty may be unwilling or unable to make timely payments or otherwise to meet its contractual obligations. If the counterparty becomes bankrupt or defaults on (or otherwise becomes unable or unwilling to perform) its payment or other obligations to the Fund, the Fund may not receive the full amount that it is entitled to receive or may experience delays in recovering the collateral or other assets held by, or on behalf of, the counterparty. If this occurs, the value of your shares in the Fund will decrease. Counterparty credit risk also includes the related risk of having concentrated exposure to such a counterparty.
R6 Shares | Guggenheim SMid Cap Value Fund | Depositary Receipt Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Depositary Receipt Risk—The Fund may hold the securities of non-U.S. companies in the form of depositary receipts. The underlying securities of the depositary receipts in the Fund’s portfolio are subject to fluctuations in foreign currency exchange rates that may affect the value of the Fund’s portfolio. In addition, the value of the securities underlying the depositary receipts may change materially when the U.S. markets are not open for trading. Investments in the underlying foreign securities also involve political and economic risks distinct from those associated with investing in the securities of U.S. issuers.
R6 Shares | Guggenheim SMid Cap Value Fund | Derivatives Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Derivatives Risk—Derivatives and other similar instruments (collectively referred to in this paragraph as “derivatives”) pose risks in addition to and greater than those associated with investing directly in securities, currencies or other investments, including risks relating to leverage, market conditions and market risk, imperfect correlations with underlying investments or the Fund’s other portfolio holdings, high price volatility, lack of availability, counterparty credit, illiquidity, valuation, operational and legal restrictions and risk. Their use is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in leverage, which may cause the Fund to be more volatile and riskier than if it had not been leveraged. Changes in the value of a derivative may also create sudden margin delivery or settlement payment obligations for the Fund, which can materially affect the performance of the Fund and its liquidity and other risk profiles. If the Investment Manager is incorrect about its expectations of market conditions, the use of derivatives could also result in a loss, which in some cases may be unlimited. In addition, the Fund’s use of derivatives may cause the Fund to realize higher amounts of short term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Some of the derivatives in which the Fund invests may be traded (and privately negotiated) in the OTC market. OTC derivatives are subject to heightened counterparty credit, legal, liquidity and valuation risks.
R6 Shares | Guggenheim SMid Cap Value Fund | Equity Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Equity Securities Risk—Equity securities include common stocks and other equity and equity-related securities (and securities convertible into stocks). The prices of equity securities generally fluctuate more than those of fixed-income investments, may rise or fall rapidly or unpredictably, and may reflect real or perceived changes in the issuing company’s financial condition and changes in the overall market or economy. A decline in the value of equity securities held by the Fund will adversely affect the value of your investment in the Fund. Common stocks generally represent the riskiest investment in a company and dividend payments (if declared) to preferred stockholders generally rank junior to payments due to a company’s debtholders. The Fund may lose a substantial part, or even all, of its investment in a company’s stock.
R6 Shares | Guggenheim SMid Cap Value Fund | Foreign Securities and Currency Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Foreign Securities and Currency Risk—Foreign securities carry unique or additional risks when compared to U.S. securities, including currency fluctuations, adverse political (including geopolitical) and economic developments, unreliable or untimely information, less liquidity and more volatility, limited legal recourse and higher transactional costs.
R6 Shares | Guggenheim SMid Cap Value Fund | Investment in Investment Vehicles Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Investment in Investment Vehicles Risk—Investing in other investment vehicles, including ETFs, closed-end funds and other mutual funds, subjects the Fund to those risks affecting the investment vehicle, including the possibility that the value of the underlying securities held by the investment vehicle could decrease or the portfolio becomes illiquid. Moreover, the Fund and its shareholders will incur its pro rata share of the underlying vehicles’ expenses, which will reduce the Fund’s performance. In addition, investments in an ETF or a listed closed-end fund are subject to, among other risks, the risk that the shares may trade at a discount or premium relative to the net asset value of the shares and the listing exchange may halt trading of the shares.
R6 Shares | Guggenheim SMid Cap Value Fund | Liquidity and Valuation Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Liquidity and Valuation Risk—It may be difficult for the Fund to purchase and sell particular investments to meet redemption requests or otherwise within a reasonable time at a fair price, or the price at which it has been valued by the Investment Manager for purposes of the Fund’s net asset value, causing the Fund to be less liquid and unable to realize what the Investment Manager believes should be the price of the investment. Valuation of portfolio investments may be difficult, such as during periods of market turmoil or reduced liquidity, and for investments that may, for example, trade infrequently or irregularly. In these and other circumstances, an investment may be valued using fair value methodologies, which are inherently subjective, reflect good faith judgments based on available information and may not accurately estimate the price at which the Fund could sell the investment at that time. These risks are heightened in a changing interest rate or volatile environment.
R6 Shares | Guggenheim SMid Cap Value Fund | Management Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Management Risk—The Fund is actively managed, which means that investment decisions are made based on investment views. There is no guarantee that the investment views will produce the desired results or expected returns. As a result of these and other factors, the Fund may lose value or fail to meet its investment objective or underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active and frequent trading that can accompany active management, also called “high turnover,” may have a negative impact on performance. Active and frequent trading may result in higher brokerage costs or mark-up charges and tax costs, which are ultimately passed on to shareholders of the Fund. Active and frequent trading may also result in adverse tax consequences.
R6 Shares | Guggenheim SMid Cap Value Fund | Market Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Market Risk—The value of, or income generated by, the investments held by the Fund may fluctuate rapidly and unpredictably. These fluctuations may be frequent and significant. In addition, the Fund may incur losses as a result of various market and economic factors, such as those affecting individual companies or issuers or particular industries, or from broader influences, such as general market conditions. In addition, developments related to economic, political (including geopolitical), social, public health, market, extreme weather, natural or man-made disasters or other conditions or events may cause volatility in financial markets and reduced liquidity in equity, credit and/or debt markets, which could adversely impact the Fund and its investments and their value and performance. Under such conditions, the Fund may experience significant redemption activity by shareholders and could be forced to sell portfolio securities or other assets at unfavorable prices in an effort to generate sufficient cash to pay redeeming shareholders. The Fund's investments may perform poorly or underperform the general securities markets or other types of securities.
R6 Shares | Guggenheim SMid Cap Value Fund | Mid Capitalization Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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.
R6 Shares | Guggenheim SMid Cap Value Fund | Quantitative Investing Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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.
R6 Shares | Guggenheim SMid Cap Value Fund | Real Estate Investments Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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 and the real estate market generally. 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 mortgages and other types of financing; changes in the real estate values and interest rates; fluctuations in occupancy levels and demand for properties or real estate-related services; decline in value of (or income generated by) the real estate; variations in rental income; and changes in financing terms that may render the sale or refinancing of properties difficult or unattractive. Real estate values or income generated by real estate may be affected by many additional factors and real estate is a cyclical business, highly sensitive to general and local economic developments and characterized by intense competition and periodic overbuilding. Real estate income and values and the real estate market may also be greatly affected by demographic trends, such as population shifts or changing tastes, preferences and values, and government actions. Real estate companies may also be affected by changing interest rates and credit quality requirements. 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.
R6 Shares | Guggenheim SMid Cap Value Fund | Regulatory and Legal Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Regulatory and Legal Risk—U.S. and non-U.S. governmental agencies and other regulators regularly implement additional regulations and legislators pass new laws that affect the investments held by the Fund, the strategies used by the Fund or the level of regulation or taxation applying to the Fund (such as regulations related to investments in derivatives and other transactions). These regulations and laws impact the investment strategies, performance, costs and operations of the Fund or taxation of shareholders.
R6 Shares | Guggenheim SMid Cap Value Fund | REIT Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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. The value of a REIT may also decline when interest rates rise and will also be affected by, among other factors, the real estate market and by the management, development or occupancy rates of the underlying properties, which may also be subject to mortgage loans and the underlying mortgage loans (and other types of financing) are subject to the risk of default. 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.
R6 Shares | Guggenheim SMid Cap Value Fund | Restricted Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Restricted Securities Risk—Restricted securities generally cannot be sold to the public and may involve a high degree of business, financial and liquidity risk, which may result in substantial losses to the Fund.
R6 Shares | Guggenheim SMid Cap Value Fund | Sector Emphasis Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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, public health 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.
R6 Shares | Guggenheim SMid Cap Value Fund | Small Capitalization Securities Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	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.
R6 Shares | Guggenheim SMid Cap Value Fund | Value Stocks Risk [Member]
Risk Return Abstract	rr_RiskReturnAbstract
Risk [Text Block]	rr_RiskTextBlock	Value Stocks Risk—Value stocks are subject to the risk that the intrinsic value of the stock may never be realized by the market or that the price goes down.
