This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may be required to pay commissions and/or other forms of compensation to a broker for transactions in Advisor Class shares, which are not reflected in the tables or the examples below. You may qualify for sales charge reductions if you and members of your family invest, or agree to invest in the future, at least $100,000 in AB Mutual Funds. More information about these and other discounts is available from your financial intermediary and in Investing in the Funds—Sales Charge Reduction Programs for Class A Shares on page 72 of this Prospectus, in Appendix B—Financial Intermediary Waivers of this Prospectus and in Purchase of Shares—Sales Charge Reduction Programs for Class A Shares on page 134 of the Fund’s Statement of Additional Information (“SAI”).

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock
The Fund pays transaction costs, such as commissions, when it buys or 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 transaction costs, which are not reflected in the Annual Fund Operating Expenses or in the Examples, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 56% of the average value of its portfolio.

Expenses Deferred Charges [Text Block] rr_ExpensesDeferredChargesTextBlock Purchases of Class A shares in amounts of $1,000,000 or more, or by certain group retirement plans, may be subject to a 1%, 1‑year contingent deferred sales charge, or CDSC, which may be subject to waiver in certain circumstances. For Class C shares, the CDSC is 0% after the first year. Class C shares automatically convert to Class A shares after eight years.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock
The Examples are intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Examples assume that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Examples also assume that your investment has a 5% return each year, that the Fund’s operating expenses stay the same and that any fee waiver and/or expense limitation is in effect for only the first year. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
 
Strategy [Heading] rr_StrategyHeading PRINCIPAL STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock
The Fund invests primarily in the equity securities of U.S. companies that the Adviser believes are attractively valued. The Adviser relies primarily upon the fundamental analysis and research of its dedicated investment team for the Fund in conducting research and making investment decisions. The team initially screens a primary research universe of largely U.S. companies for attractive security valuation and business models. Once appropriate candidates have been identified for further analysis, the team conducts fundamental research to better understand the economics of the company’s business model. In evaluating a company for potential inclusion in the Fund, the Adviser takes into account many factors that it believes bear on the company’s ability to perform in the future, including competitive advantages and fundamentals such as strong cash-flow generation, sustainable growth and strong balance sheets.
At different times, and as a result of how individual companies are valued in the market, the Fund may be attracted to investments in companies with different market capitalizations (i.e., large-, mid‑ or small-capitalization) or companies engaged in particular types of business (e.g., banks and other financial institutions), although the Fund does not intend to concentrate in any particular industries or businesses. The Fund’s portfolio emphasis upon particular industries or sectors will be a by‑product of the stock selection process rather than the result of assigned targets or ranges. In managing the Fund, the Adviser will not seek to have a bias either towards securities typically considered growth stocks or securities typically considered value stocks.
The Fund may enter into derivatives transactions, such as options, futures contracts, forwards, and swaps. The Fund may use options strategies involving the purchase and/or writing of various combinations of call and/or put options, including on individual securities and stock indices, futures contracts (including futures contracts on individual securities and stock indices) or shares of exchange-traded funds (“ETFs”). These transactions may be used, for example, in an effort to earn extra income, to adjust exposure to individual securities or markets, or to protect all or a portion of the Fund’s portfolio from a decline in value, sometimes within certain ranges.
Risk [Heading] rr_RiskHeading PRINCIPAL RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock
•  
Market Risk: The value of the Fund’s investments will fluctuate as the stock or bond market fluctuates. The value of its investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other events, including public health crises (including the occurrence of a contagious disease or illness), that affect large portions of the market. It includes the risk that a particular style of investing, such as the Fund’s value approach, may be underperforming the market generally. 
•  
Capitalization Risk: Investments in small-capitalization companies may be more volatile than investments in large-capitalization companies. Investments in small-capitalization companies may have additional risks because these companies have limited product lines, markets or financial resources. 
•  
Currency Risk: Fluctuations in currency exchange rates may negatively affect the value of the Fund’s investments or reduce its returns. 
•  
Derivatives Risk: Derivatives may be difficult to price or unwind and leveraged so that small changes may produce disproportionate losses for the Fund. Derivatives, especially over‑the‑counter derivatives, are also subject to counterparty risk, which is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable or unwilling to honor its contractual obligations to the Fund. 
•  
Industry/Sector Risk: Investments in a particular industry or group of related industries may have more risk because market or economic factors affecting that industry could have a significant effect on the value of the Fund’s investments. 
•  
Management Risk: The Fund is subject to management risk because it is an actively-managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected. 
As with all investments, you may lose money by investing in the Fund.

Purchases of Class A shares in amounts of $1,000,000 or more, or by certain group retirement plans, may be subject to a 1%, 1‑year contingent deferred sales charge, or CDSC, which may be subject to waiver in certain circumstances.
[2]
The Adviser has contractually agreed to waive its management fees and/or to bear certain expenses of the Fund. In addition to that agreement, in connection with the Fund’s investments in AB Government Money Market Portfolio (the “Money Market Portfolio”) (except for the investment of any cash collateral from securities lending), the Adviser has contractually agreed to waive its management fee from the Fund and/or reimburse other expenses of the Fund in an amount equal to the Fund’s pro rata share of the Money Market Portfolio’s effective management fee, as included in “Acquired Fund Fees and Expenses”. Each of the agreements will remain in effect until February 28, 2023 and may only be terminated or changed with the consent of the Fund’s Board of Directors. In addition, each of the agreements will be automatically extended for one‑year terms unless the Adviser provides notice of termination to the Fund at least 60 days prior to the end of the period.
[3] Amount is less than .005%.
[4] After-tax returns: – Are shown for Class A shares only and will vary for the other Classes of shares because these Classes have different expense ratios; – Are estimates based on the highest historical individual federal marginal income tax rates, and do not reflect the impact of state and local taxes; actual after-tax returns depend on an individual investor’s tax situation and are likely to differ from those shown; and – Are not relevant to investors who hold fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.
[5]
For Class C shares, the CDSC is 0% after the first year. Class C shares automatically convert to Class A shares after eight years.
[6]
If you did not redeem your shares at the end of the period, your expenses would be decreased by approximately $100.

Inception date for Class Z shares is 10/15/13. Performance information for periods prior to the inception of Class Z shares is the performance of the Fund’s Class A shares adjusted to reflect the expenses of the Class Z shares.
