Strategy [Heading]	PRINCIPAL STRATEGIES
Strategy Narrative [Text Block]	The Fund invests primarily in domestic equity securities of companies selected by the Fund’s Adviser for their growth potential within various market sectors. The Fund invests, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of companies meeting the Adviser’s growth criteria. For purposes of this policy, companies meeting the Adviser’s growth criteria are those companies with securities included in any one of the following indexes: the Russell 3000^® Growth Index, the MSCI ACWI IMI Growth, and the Morningstar Global All‑Cap Growth TME. When selecting securities, the Adviser seeks companies that have experienced management teams, strong market positions, and the potential to deliver greater-than-expected earnings growth rates. In managing the Fund, the Adviser allocates investments among broad sector groups and selects specific investments based on the fundamental company research conducted by the Adviser’s internal research staff, assessing the current and forecasted investment opportunities and conditions, as well as diversification and risk considerations. The Adviser’s research focus is on companies with high sustainable growth prospects, high or improving return on invested capital, transparent business models, and clear competitive advantages. The Fund has the flexibility to invest across the capitalization spectrum. The Fund is designed for those seeking exposure to companies of various sizes, and typically has substantial investments in both large-capitalization companies and mid‑capitalization companies, and may also invest in small-capitalization companies. 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.

Strategy [Heading]	PRINCIPAL STRATEGIES
Strategy Narrative [Text Block]	The Fund invests primarily in equity securities, either directly or through underlying investment companies advised by the Adviser (“Underlying Portfolios”). A majority of the Fund’s assets are expected to be invested directly in U.S. large‑cap equity securities, primarily common stocks, in accordance with the Adviser’s U.S. Strategic Equities investment strategy (“U.S. Strategic Equities”), as described below. In addition, the Fund seeks to achieve exposure to international large‑cap equity securities through investments in other registered investment companies advised by the Adviser, which may include International Strategic Equities Portfolio of Bernstein Fund, Inc. (“Bernstein International Strategic Equities Portfolio”). The Fund also invests in other Underlying Portfolios to efficiently gain exposure to certain other types of equity securities, including small- and mid‑cap and emerging market equity securities. An Underlying Portfolio is selected based on the segment of the equity market to which the Underlying Portfolio provides exposure, its investment philosophy, and how it complements and diversifies the Fund’s overall portfolio. Under U.S. Strategic Equities, portfolio managers of the Adviser that specialize in various investment disciplines identify high-conviction large‑cap equity securities based on their fundamental investment research for potential investment by the Fund. These securities are then assessed in terms of both this fundamental research and quantitative analysis in creating the Fund’s portfolio. In applying the quantitative analysis, the Adviser considers a number of metrics that historically have provided some indication of favorable future returns, including metrics related to valuation, quality, investor behavior and corporate behavior. Bernstein International Strategic Equities Portfolio focuses on investing in non‑U.S. large‑cap and mid‑cap equity securities. Bernstein International Strategic Equities Portfolio follows a strategy similar to U.S. Strategic Equities, but in the international context. Fluctuations in currency exchange rates can have a dramatic impact on the returns of foreign equity securities. The Adviser may employ currency hedging strategies in the Fund or the Underlying Portfolios, including the use of currency-related derivatives, to seek to reduce currency risk in the Fund or the Underlying Portfolios, but it is not required to do so. The Fund is managed without regard to tax considerations.
AB All Market Total Return Portfolio
Prospectus [Line Items]
Strategy [Heading]	PRINCIPAL STRATEGIES
Strategy Narrative [Text Block]	The Adviser allocates the Fund’s investments primarily among a number of asset classes, including equity securities, fixed-income securities, and a number of alternative asset classes and alternative investment strategies. The Fund pursues a global strategy, typically investing in securities of issuers located in the United States and in other countries throughout the world, including emerging market countries. Under normal circumstances, at least 40% of the Fund’s net assets will be invested in securities of non‑U.S. issuers. The Fund’s investments in equity securities of issuers consist primarily of securities of large-capitalization companies, but include securities of small- and mid‑capitalization companies to a lesser extent, and include derivatives related to equity securities. In selecting equity securities for the Fund, the Adviser uses fundamental and quantitative analysis with the goal of generating returns primarily from security selection rather than price movements in equity securities generally. Fixed-income securities include corporate and sovereign debt securities as well as interest rate derivatives and credit derivatives such as credit default swaps. Fixed-income securities also include debt securities with lower credit ratings (commonly known as “junk bonds”). In selecting fixed-income securities for the Fund, the Adviser attempts to take advantage of inefficiencies that it believes exist in the global fixed-income markets. These inefficiencies arise from investor behavior, market complexity, and the investment limitations to which investors are subject. Alternative investments include various instruments the returns on which are expected to have low correlation with returns on equity and fixed-income securities, such as commodities and related derivatives, real estate-related securities, and inflation-indexed securities. Alternative investment strategies that may be pursued by the Fund directly or indirectly through investment in other registered investment companies include (i) long/short equity strategies through which the Fund takes long positions in certain securities in the expectation that they will increase in value and takes short positions in other securities in the expectation that they will decrease in value; (ii) strategies that consider macroeconomic and technical factors to identify and exploit opportunities across global asset classes; and (iii) event-driven strategies that invest in the securities of companies that are expected to become the subject of major corporate events and companies in which an active role in company management has been taken or sought by a third-party investor. The Adviser tactically adjusts the Fund’s asset class exposure utilizing both fundamental analysis and quantitative tools. These quantitative tools are employed by the Adviser to gauge fluctuations in the risk/return profile of various asset classes. Tactical adjustments aim to capitalize on changing market conditions to mitigate volatility or enhance long-term return potential. For example, the Adviser may seek to reduce the Fund’s risk exposure to one or more assets classes when the combined research suggests that market risks relevant to those asset classes are rising but return opportunities are declining. In addition to merely increasing or decreasing asset class exposure by buying or selling securities of that asset class, the Adviser may make tactical adjustments for the Fund by utilizing derivatives. The Adviser intends to utilize a variety of derivatives in its management of the Fund. As noted above, the Adviser may use derivatives to gain exposure to various asset classes, and may cause the Fund to enter into derivatives to express its tactical views. As a result of the use of derivatives, the Fund will frequently be leveraged, with net investment exposure substantially in excess of net assets. While the Fund may seek to gain exposure to physical commodities traded in the commodities markets through investments in a variety of derivative instruments, the Adviser expects to seek exposure to commodities and commodities-related instruments and derivatives primarily through investments in AB All Market Total Return Portfolio (Cayman), Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “All Market Total Return Subsidiary”). The All Market Total Return Subsidiary is advised by the Adviser and has the same investment objective and substantially similar investment policies and restrictions as the Fund except that the All Market Total Return Subsidiary, unlike the Fund, may invest, without limitation, in commodities and commodities-related instruments. The Fund is subject to the risks associated with the commodities, derivatives and other instruments in which the All Market Total Return Subsidiary invests, to the extent of its investment in the All Market Total Return Subsidiary. The Fund limits its investment in the All Market Total Return Subsidiary to no more than 25% of its total assets. Investment in the All Market Total Return Subsidiary is expected to provide the Fund with commodity exposure within the limitations of federal tax requirements that apply to the Fund. Currency exchange rate fluctuations can have a dramatic impact on returns. The Fund’s foreign currency exposures will come from investment in securities priced or denominated in foreign currencies and from direct holdings in foreign currencies and currency-related derivatives. The Adviser may seek to hedge all or a portion of the currency exposure resulting from Fund investments or decide not to hedge this exposure. The Adviser may seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives.

The Fund seeks to maximize after‑tax returns to shareholders by taking into account the tax impact of buy and sell investment decisions on its shareholders. For example, the Adviser may sell certain securities in order to realize capital losses. Capital losses may be used to offset realized capital gains. To minimize capital gains distributions, the Adviser may sell securities held by the Fund with the highest cost basis. The Adviser may monitor the length of time the Fund has held an investment to evaluate whether the investment should be sold at a short-term gain or held for a longer period so that the gain on the investment will be taxed at the lower long-term rate. In making this decision, the Adviser considers whether, in its judgment, the risk of continued exposure to the investment is worth the tax savings of a lower capital gains rate. There can be no assurance that any of these strategies will be effective or that their use will not adversely affect the gross returns of the Fund.
