Expense Narrative [Text Block] | rr_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. 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 AllianceBernstein 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 53 of this Prospectus and in Purchase of Shares--Sales Charge Reduction Programs for Class A Shares on page 113 of the Funds' SAI. | ||||||||||

Portfolio Turnover [Heading] | rr_PortfolioTurnoverHeading | PORTFOLIO TURNOVER | ||||||||||
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 88% of the average value of its portfolio. | ||||||||||

Expense Example [Heading] | rr_ExpenseExampleHeading | EXAMPLES | ||||||||||
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 and that the Fund's operating expenses stay the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: | ||||||||||
Expense Example, No Redemption, By Year, Caption [Text] | rr_ExpenseExampleNoRedemptionByYearCaption | For the share classes listed below, you would pay the following expenses if you did not redeem your shares at the end of the period: | ||||||||||
Strategy [Heading] | rr_StrategyHeading | PRINCIPAL STRATEGIES | ||||||||||
Strategy Narrative [Text Block] | rr_StrategyNarrativeTextBlock | The Fund invests primarily in a diversified portfolio of equity securities with relatively smaller capitalizations as compared to the overall U.S. market. Under normal circumstances, the Fund invests at least 80% of its net assets in equity securities of smaller companies. For these purposes, "smaller companies" are those that, at the time of investment, fall within the lowest 20% of the total U.S. equity market capitalization (excluding, for purposes of this calculation, companies with market capitalizations of less than $10 million). As of June 30, 2012, there were approximately 4,230 smaller companies, and those smaller companies had market capitalizations ranging up to approximately $9.3 billion. Because the Fund's definition of smaller companies is dynamic, the limits on market capitalization will change with the markets. The Fund may invest in any company and industry and in any type of equity security with potential for capital appreciation. It invests in well-known and established companies and in new and less-seasoned companies. The Fund's investment policies emphasize investments in companies that are demonstrating improving financial results and a favorable earnings outlook. The Fund may invest in foreign securities. When selecting securities, the Adviser typically looks for companies that have strong, experienced management teams, strong market positions, and the potential to support greater than expected earnings growth rates. In making specific investment decisions for the Fund, the Adviser combines fundamental and quantitative analysis in its stock selection process. The Fund may periodically invest in the securities of companies that are expected to appreciate due to a development particularly or uniquely applicable to that company regardless of general business conditions or movements of the market as a whole. Normally, the Fund invests in about 95-125 companies broadly diversified by sector. The Fund invests primarily in equity securities but may also invest in other types of securities, such as preferred stocks. The Fund may, at times, invest in shares of ETFs in lieu of making direct investments in securities. ETFs may provide more efficient and economical exposure to the types of companies and geographic locations in which the Fund seeks to invest than direct investments. The Fund may also invest up to 20% of its total assets in rights or warrants. 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 indexes, futures contracts (including futures contracts on individual securities and stock indexes) or shares of 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. |
