Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, at least 80% of the Fund's net assets (plus the amount of any borrowings for investment purposes) are invested in securities of small capitalization companies. The Fund considers a company to be a small capitalization company if it has a market capitalization, at the time of investment, within the range of the market capitalizations of the companies in the Russell 2000® Index. The capitalization range of that index is subject to change over time due to market activity or changes in the composition of the index. As of December 31, 2017, the market capitalizations of the companies in the Russell 2000 Index ranged from $22.5 million to $9.3 billion.

The Fund's investment sub-advisor, Bahl & Gaynor Inc., d/b/a Bahl & Gaynor Investment Counsel ("Bahl & Gaynor") pursues its small cap growth strategy by focusing on high-quality dividend-paying stocks. Quantitative tools are initially used for screening purposes, but Bahl & Gaynor's investment process is primarily driven by fundamental, bottom-up, company-focused processes. The investment process begins by quantitatively screening the stock universe to identify companies with perceived competitive advantages by evaluating their historical revenue growth, earnings growth, long-term debt/capital, dividend history and cash flows. Bahl & Gaynor conducts extensive fundamental research on potential portfolio companies to determine which stock(s) provide the best risk/reward opportunities for inclusion in the portfolio. Bahl & Gaynor typically will sell an investment if the company's fundamentals have changed or the company's market capitalization (stock market worth) moves outside of the small cap range.

Although the Fund seeks investments across a number of sectors, from time to time, based on portfolio positioning to reflect its benchmark index, the Fund may have significant positions in particular sectors. The Fund may have significant exposure to the Information Technology sector. However, as the sector composition of the Fund's portfolio changes over time, the Fund's exposure to the Information Technology sector may be lower at a future date, and the Fund's exposure to other market sectors may be higher.

The Fund's equity investments may include common stocks, depositary receipts, and real estate investments trusts ("REITs").

The Fund may invest cash balances in other investment companies, including money market funds and may purchase and sell futures contracts to gain market exposure on cash balances in anticipation of liquidity needs. The Fund may lend its securities to broker-dealers and other institutions to earn additional income.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund are:

Cybersecurity and Operational Risk
The Fund and its service providers, and shareholders' ability to transact with the Fund, may be negatively impacted due to operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Dividend Risk
An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks.

Equity Investments Risk
Equity securities are subject to investment and market risk. The Fund's investments in equity securities may include common stocks, depositary receipts, and REITs. Such investments may expose the Fund to additional risks.

Common Stock. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.
Depositary Receipts. Depositary receipts are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency exchange rate fluctuations, political and financial instability in the home country of a particular depositary receipt or foreign stock, less liquidity and more volatility, less government regulation and supervision and delays in transaction settlement.
REITs. Investments in REITs are subject to the risks associated with investing in the real estate industry such as adverse developments affecting the real estate industry and real property values. REITs also are dependent upon the skills of their managers and are subject to heavy cash flow dependency or self-liquidation. Domestic REITs could be adversely affected by failure to qualify for tax-free "pass-through" of distributed net income and net realized gains under the Internal Revenue Code of 1986, as amended, or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. REITs typically incur fees that are separate from those incurred by the Fund. Accordingly, the Fund's investment in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs' operating expenses, in addition to paying Fund expenses. The value of REIT common stock may decline when interest rates rise.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing and financial reporting standards, (5) increased volatility, (6) different government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays in transaction settlement in some foreign markets.

Futures Contracts Risk
Futures contracts are derivative instruments where the parties agree to a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience potentially dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract).

Growth Companies Risk
Growth companies are expected to increase their earnings at a certain rate. When these expectations are not met, the prices of these stocks may go down, even if earnings showed an absolute increase. Growth company stocks may lack the dividend yield that can cushion stock prices in market downturns.

Investment Risk
An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Issuer Risk
The value of, and/or the return generated by, a security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets.

Market Risk
The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably based on overall economic conditions and other factors. The value of a security may decline due to general market conditions which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investment sentiment generally. Changes in the financial condition of a single issuer can impact a market as a whole. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Model and Data Risk
Models and data are used to screen potential investments for the Fund. When models or data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Some of the models used by the sub-advisor are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.

Other Investment Companies Risk
The Fund may invest in shares of other registered investment companies, including money market funds. To the extent that the Fund invests in shares of other registered investment companies, the Fund will indirectly bear the fees and expenses charged by those investment companies in addition to the Fund's direct fees and expenses and will be subject to the risks associated with investments in those companies. For example, money market funds are subject to interest rate risk, credit risk, and market risk.

Sector Risk
When the Fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the Fund were invested more evenly across sectors.

Information Technology Sector Risk. The market prices of information technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices.

Securities Lending Risk
To the extent the Fund lends its securities, it may be subject to the following risks: i) borrowers of the Fund's securities typically provide collateral in the form of cash that is reinvested in securities, ii) the securities in which the collateral is invested may not perform sufficiently to cover the return collateral payments owed to borrowers, iii) delays may occur in the recovery of securities from borrowers, which could interfere with the Fund's ability to vote proxies or to settle transactions, and iv) there is the risk of possible loss of rights in the collateral should the borrower fail financially.

Securities Selection Risk
Securities selected by the sub-advisor or the Manager for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objectives.

Small Capitalization Companies Risk
Investing in the securities of small capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies. Since smaller companies may have narrower commercial markets, and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity. The securities of small capitalization companies and they can be particularly sensitive to expected changes in interest rates, borrowing costs and earnings.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local income taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. If you are a tax-exempt entity or hold your Fund shares through a tax-deferred arrangement, such as an individual retirement account ("IRA") or a 401(k) plan, the after-tax returns do not apply to your situation.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests in a diversified portfolio of large capitalization companies that are listed on the New York Stock Exchange, NYSE MKT, and NASDAQ. Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in stocks from among those in the large-cap growth category at the time of purchase. For purposes of the Fund's investments, "large-cap stocks" are stocks of companies whose market capitalization falls within the range of the Russell 1000® Index at the time of investment. The Russell 1000 Index is an unmanaged, market value weighted index, which measures performance of approximately 1,000 of the largest companies in the U.S. equity market. The Russell 1000 Index is reconstituted from time to time. The market capitalization range for the Russell 1000 Index was $1.1 billion to $868.9 billion as of December 31, 2017.

Growth stocks are those that the Fund's sub-advisor, Bridgeway Capital Management, Inc. ("Bridgeway Capital") believes have above average prospects for economic growth. Generally, these are stocks represented in the Russell 1000® Growth Index, but may also include stocks of other companies with similar "growth" characteristics whose market capitalizations are within the range of the Russell 1000 Index. The Russell 1000 Growth Index includes those Russell 1000 companies with higher price-to-book ratios and higher forecasted growth values.

The Fund's investments may include common stocks, preferred stocks, securities convertible into U.S. common stocks, real estate investment trusts ("REITs"), depositary receipts and dollar-denominated foreign stocks traded on U.S. exchanges (collectively referred to as "stocks"). The Fund also may invest in stocks of mid-capitalization companies.

Bridgeway Capital selects stocks within the large-cap growth category using a statistically driven approach. Bridgeway Capital will not necessarily sell a stock if it "migrates" outside the market capitalization range of the Russell 1000 Index after purchase. As a result, due to such "migration" or other market movements, the Fund may have less than 80% of its assets in large-cap stocks at any point in time. Based on statistically driven rules, securities are sold when the reasons for selecting the stock are no longer valid or when necessary to maintain the risk profile of the overall Fund.

Although the Fund seeks investments across a number of sectors, from time to time, based on portfolio positioning to reflect its benchmark index, the Fund may have significant positions in particular sectors. The Fund may have significant exposure to the Information Technology sector. However, as the sector composition of the Fund's portfolio changes over time, the Fund's exposure to the Information Technology sector may be lower at a future date, and the Fund's exposure to other market sectors may be higher.

While the Fund is actively managed for long-term total return on capital, Bridgeway Capital seeks to minimize capital gain distributions as part of a tax management strategy. For example, Bridgeway Capital tracks tax lots and periodically harvests capital losses to offset realized capital gains from stock sales or mergers. (A capital gain occurs when the Fund sells a stock at a higher price than the purchase price. A capital loss occurs when the Fund sells a stock at a lower price than the purchase price.) The successful application of this method is intended to result in a more tax-efficient fund than would otherwise be the case.

The Fund may also invest cash balances in other investment companies, including money market funds, and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs. The Fund may lend its securities to broker-dealers and other institutions to earn additional income.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund are:

Allocation Risk
The Manager's and the sub-advisor's judgments about, and allocations among, asset classes and market exposures may adversely affect the Fund's performance.

Cybersecurity and Operational Risk
The Fund and its service providers, and shareholders' ability to transact with the Fund, may be negatively impacted due to operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Equity Investments Risk
Equity securities are subject to investment and market risk. The Fund's investments in equity securities may include common stocks, preferred stocks, securities convertible into or exchangeable for common stocks, REITs, depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges. Such investments may expose the Fund to additional risks.

Common Stock. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.
Convertible Securities. Convertible securities are subject to the risk that the credit standing of the issuer may have an effect on the convertible securities' investment value. Convertible securities are also sensitive to movements in interest rates.
Depositary Receipts. Depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency exchange rate fluctuations, political and financial instability in the home country of a particular depositary receipt or foreign stock, less liquidity and more volatility, less government regulation and supervision and delays in transaction settlement.
Preferred Stock. Preferred stocks are sensitive to movements in interest rates. Preferred stocks may be less liquid than common stocks and, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred stocks generally are payable at the discretion of an issuer and after required payments to bond holders.
REITs. Investments in REITs are subject to the risks associated with investing in the real estate industry such as adverse developments affecting the real estate industry and real property values. REITs also are dependent upon the skills of their managers and are subject to heavy cash flow dependency or self-liquidation. Domestic REITs could be adversely affected by failure to qualify for tax-free "pass-through" of distributed net income and net realized gains under the Internal Revenue Code of 1986, as amended ("Internal Revenue Code"), or to maintain their exemption from registration under the Investment Company Act of 1940, as amended ("Investment Company Act"). REITs typically incur fees that are separate from those incurred by the Fund. Accordingly, the Fund's investment in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs' operating expenses, in addition to paying Fund expenses. The value of REIT common stock may decline when interest rates rise.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing and financial reporting standards, (5) increased volatility, (6) different government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays in transaction settlement in some foreign markets.

Futures Contracts Risk
Futures contracts are derivative instruments where the parties agree to a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. Futures contracts may experience potentially dramatic price changes (losses) and imperfect correlation between the price of the contract and the underlying security or index, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract).

Growth Companies Risk
Growth companies are expected to increase their earnings at a certain rate. When these expectations are not met, the prices of these stocks may go down, even if earnings showed an absolute increase. Growth company stocks may lack the dividend yield that can cushion stock prices in market downturns.

Investment Risk
An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Issuer Risk
The value of, and/or the return generated by, a security may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets.

Large Capitalization Companies Risk
The securities of large market capitalization companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain the high growth rates of successful smaller companies, especially during periods of economic expansion.

Market Risk
The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably based on overall economic conditions and other factors. The value of a security may decline due to general market conditions which are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investment sentiment generally. Changes in the financial condition of a single issuer can impact a market as a whole. A rise in protectionist trade policies, and the possibility of changes to some international trade agreements, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Mid-Capitalization Companies Risk
Investing in the securities of mid-capitalization companies involves greater risk and the possibility of greater price volatility than investing in larger capitalization and more established companies. Since mid-capitalization companies may have narrower commercial markets and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity, and they can be particularly sensitive to expected changes in interest rates, borrowing costs and earnings.

Model and Data Risk
Models and data are used to screen potential investments for the Fund. When models or data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks. Some of the models used by the sub-advisor are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data.

Other Investment Companies Risk
The Fund may invest in shares of other registered investment companies, including money market funds. To the extent that the Fund invests in shares of other registered investment companies, the Fund will indirectly bear the fees and expenses charged by those investment companies in addition to the Fund's direct fees and expenses and will be subject to the risks associated with investments in those companies. For example, money market funds are subject to interest rate risk, credit risk, and market risk.

Redemption Risk
The Fund may experience periods of high levels of redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. The sale of assets to meet redemption requests may create net capital gains, which could cause the Fund to have to distribute substantial capital gains. Redemption risk is heightened during periods of declining or illiquid markets. Heavy redemptions could hurt the Fund's performance.

Risk of Programming and Modeling Error
The success of the sub-advisor's investment strategy depends largely on the effectiveness of its quantitative research models and investment programs. The programs may not react as expected to market events resulting in losses for the Fund. Additionally, programs may become outdated or experience malfunctions which may not be identified by the sub-advisor and therefore may also result in losses to the Fund.

Sector Risk
When the Fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the Fund were invested more evenly across sectors.

Information Technology Sector Risk. The market prices of information technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices.

Securities Lending Risk
To the extent the Fund lends its securities, it may be subject to the following risks: i) borrowers of the Fund's securities typically provide collateral in the form of cash that is reinvested in securities, ii) the securities in which the collateral is invested may not perform sufficiently to cover the return collateral payments owed to borrowers, iii) delays may occur in the recovery of securities from borrowers, which could interfere with the Fund's ability to vote proxies or to settle transactions, and iv) there is the risk of possible loss of rights in the collateral should the borrower fail financially.

Securities Selection Risk
Securities selected by the sub-advisor or the Manager for the Fund may not perform to expectations. This could result in the Fund's underperformance compared to other funds with similar investment objectives.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

On February 5, 2016, the Fund acquired all the assets and assumed all the liabilities of the Fund's predecessor. The Institutional Class shares of the Fund have adopted the performance history and financial statements of the Fund's predecessor. The chart and the table below show the performance of the Fund's Institutional Class shares, which, prior to February 5, 2016, is the performance of the Fund's predecessor. The table below also shows the performance of the Fund's A Class, C Class, Y Class and Investor Class shares. Performance for the A Class, C Class, Y Class and Investor Class shares represents the returns achieved by the Fund's predecessor from January 1, 2008 through February 4, 2016, and the performance of each of the Fund's respective share classes from February 5, 2016 through December 31, 2017. In each case, the newer share classes would have had similar annual returns to the Fund's predecessor because the shares of each class represent investments in the same portfolio securities. However, the older share class had different expenses than the newer share classes, which would affect performance. Performance information for R6 Class shares of the Fund is not provided because this share class had not commenced operations prior to the date of this Prospectus. You may obtain updated performance information on the Fund's website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

The bar chart and table below provide an indication of risk by showing how the Fund's performance has varied from year to year. The table shows how the Fund's performance compares to a broad-based market index, which is the Fund's benchmark index and was the benchmark index of the Fund's predecessor.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local income taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. The return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. If you are a tax-exempt entity or hold your Fund shares through a tax-deferred arrangement, such as an individual retirement account ("IRA") or a 401(k) plan, the after-tax returns do not apply to your situation. After-tax returns are shown only for the Fund's Institutional Class shares; after-tax returns for other share classes will vary.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests in a diversified portfolio of stocks of large capitalization companies that are listed on the New York Stock Exchange, NYSE MKT, and NASDAQ. Under normal market conditions, at least 80% of Fund net assets (plus borrowings for investment purposes) are invested in stocks from among those in the large-cap value category at the time of purchase. For purposes of the Fund's investment portfolio, "large-cap stocks" are those whose market capitalization (stock market worth) falls within the range of the Russell 1000® Index at the time of investment. The Russell 1000® Index measures the performance of the 1,000 largest U.S. companies based on total market capitalization. As of December 31, 2017, the market capitalizations of the companies in the Russell 1000® Index ranged from $1.1 billion to $868.9 billion.

The Fund's sub-advisor, Bridgeway Capital Management, Inc. ("Bridgeway Capital"), selects stocks within the large-cap value category for the Fund using a proprietary statistically driven approach. Value stocks are those Bridgeway Capital believes are priced cheaply relative to some financial measures of worth, such as the ratio of price to earnings, price to sales, or price to cash flow. Generally, these are stocks represented in the Russell 1000® Value Index, plus large capitalization stocks with similar "value" characteristics. The Russell 1000® Value Index includes those Russell 1000® companies with lower price-to-book ratios and lower forecasted growth values. Based on statistically driven rules, securities are sold when the reasons for selecting the stock are no longer valid or when necessary to maintain the risk profile of the overall Fund.

The Fund's investments may include common stocks, preferred stocks, securities convertible into U.S. common stocks, real estate investment trusts ("REITs"), American Depositary Receipts ("ADRs") and U.S. dollar-denominated foreign stocks traded on U.S. exchanges (collectively referred to as "stocks"). The Fund also may invest in stocks of mid-capitalization companies.

The Fund may also invest cash balances in other investment companies, including money market funds, and may purchase and sell futures contracts to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs. The Fund may lend its securities to broker-dealers and other institutions to earn additional income.

While the Fund is actively managed for long-term total return, Bridgeway Capital seeks to minimize capital gain distributions as part of a tax management strategy. For example, Bridgeway Capital tracks tax lots and periodically harvests capital losses to offset realized capital gains from stock sales or mergers. (A capital gain occurs when the Fund sells a stock at a higher price than the purchase price. A capital loss occurs when the Fund sells a stock at a lower price than the purchase price.) The successful application of this method is intended to result in a more tax-efficient fund than would otherwise be the case.

Although the Fund seeks investments across a number of sectors, from time to time, based on portfolio positioning to reflect its benchmark index, the Fund may have significant positions in particular sectors. The Fund may have significant exposure to the Financial Services sector. However, as the sector composition of the Fund's portfolio changes over time, the Fund's exposure to the Financial Services sector may be lower at a future date, and the Fund's exposure to other market sectors may be higher.

The Fund uses income to pursue its investment objective. Income is achieved almost exclusively from dividend-paying stocks held by the Fund. However, not all stocks held by the Fund pay dividends.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund are:

Allocation Risk
The Manager's and the sub-advisor's judgments about, and allocations among, asset classes and market exposures may adversely affect the Fund's performance.

Cybersecurity and Operational Risk
The Fund and its service providers, and shareholders' ability to transact with the Fund, may be negatively impacted due to operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Dividend Risk
An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks.

Equity Investments Risk
Equity securities are subject to investment and market risk. The Fund's investments in equity securities may include common stocks, preferred stocks, securities convertible into or exchangeable for common stocks, REITs, depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges. Such investments may expose the Fund to additional risks.

Common Stock. The value of a company's common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.
Convertible Securities. Convertible securities are subject to the risk that the credit standing of the issuer may have an effect on the convertible securities' investment value. Convertible securities are also sensitive to movements in interest rates.
Depositary Receipts. Depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency exchange rate fluctuations, political and financial instability in the home country of a particular depositary receipt or foreign stock, less liquidity and more volatility, less government regulation and supervision and delays in transaction settlement.
Preferred Stock. Preferred stocks are sensitive to movements in interest rates. Preferred stocks may be less liquid than common stocks and, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred stocks generally are payable at the discretion of an issuer and after required payments to bond holders.
REITs. Investments in REITs are subject to the risks associated with investing in the real estate industry such as adverse developments affecting the real estate industry and real property values. REITs also are dependent upon the skills of their managers and are subject to heavy cash flow dependency or self-liquidation. Domestic REITs could be adversely affected by failure to qualify for tax-free "pass-through" of distributed net income and net realized gains under the Internal Revenue Code of 1986, as amended ("Internal Revenue Code"), or to maintain their exemption from registration under the Investment Company Act of 1940, as amended ("Investment Company Act"). REITs typically incur fees that are separate from those incurred by the Fund. Accordingly, the Fund's investment in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs' operating expenses, in addition to paying Fund expenses. The value of REIT common stock may decline when interest rates rise.
