Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other portfolios. The Example assumes that you invest $10,000 in the Portfolio for the periods indicated, that your investment has a 5% return each year, that the Portfolio’s operating expenses remain the same, and that the Expense Limitation Arrangement is not renewed. This Example does not reflect any Contract-related fees and expenses including redemption fees (if any) at the Contract level. If such fees and expenses were reflected, the total expenses would be higher. Although your actual costs may be higher or lower, based on these assumptions, whether you redeem or hold your shares, your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Equitable Investment Management Group, LLC (“EIM” or “Adviser”) invests the Portfolio’s assets across various equity and fixed income asset categories using a tactical asset allocation strategy. Under normal market conditions, the Portfolio invests at least 80% of its net assets, plus borrowings for investment purposes, in other mutual funds and in exchange traded securities of other investment companies. The Portfolio pursues its investment objective by investing in other mutual funds in the same fund complex as the Portfolio (affiliated “Underlying Portfolios”) as well as in other mutual funds outside the fund complex (unaffiliated “Underlying Portfolios”) and in exchange traded securities of other investment companies (“Underlying ETFs”) comprising various equity and fixed income asset categories. The other mutual funds in the same fund complex as the Portfolio are managed by the Adviser or Equitable Investment Management, LLC, an affiliate of the Adviser. The Adviser, under the oversight of the Trust’s Board of Trustees, has established an asset allocation target for the Portfolio. This target is the approximate percentage of the Portfolio’s assets that will be invested in equity investments or fixed income investments (referred to herein as “asset classes”) as represented by the primary holdings (as described in the prospectuses) of the Underlying Portfolios and Underlying ETFs in which the Portfolio invests. The Portfolio’s current target allocation for long-term investments is approximately 40% of its assets in equity investments and approximately 58% of its assets in fixed income investments through investments in Underlying Portfolios and Underlying ETFs. The Portfolio also holds approximately 2% of its assets in cash and cash-equivalent instruments. The target allocations to the equity and fixed income asset classes may be changed by the Adviser and the Trust’s Board of Trustees without notice or shareholder approval. The Portfolio’s allocations to equity investments and fixed income investments may deviate from the target allocations by up to 15% for various reasons, including the Adviser’s tactical views, in response to changing market conditions, or as a result of appreciation or depreciation of an asset class. Subject to the asset allocation target set forth above, the Portfolio seeks to invest its assets among the Underlying Portfolios and Underlying ETFs to achieve a diversified exposure across multiple asset categories. The asset categories of the Underlying Portfolios and Underlying ETFs in which the Portfolio currently expects to invest are as follows: Equity Asset Categories U.S. Large Cap Equity U.S. Small & Mid Cap Equity International Markets Equity Emerging Markets Equity Global Equity U.S. Equity U.S. Growth Equity U.S. Value Equity Fixed Income Asset Categories Investment Grade Bond High Yield (“Junk”) Bond The percentage of the Portfolio’s assets exposed to an asset category will vary from time to time, and the Portfolio may not invest in all of the asset categories listed. The Adviser may allocate the Portfolio’s assets to additional asset categories in the future. The investment grade bond and high yield (“junk”) bond asset categories may include both U.S. and foreign (including emerging markets) issuers. The Portfolio may invest up to 25% of its total assets in the high yield bond asset category. The Portfolio is not limited with respect to the maturity, duration or credit quality of the fixed income securities in which it invests. The Underlying Portfolios and Underlying ETFs may invest in fixed income investments of any maturity, duration or credit quality. The fixed income investments in which the Underlying Portfolios and Underlying ETFs may invest include primarily government, corporate, and investment grade agency mortgage-backed and asset-backed securities. The Adviser employs a tactical asset allocation strategy in managing the Portfolio’s weightings in the asset classes and asset categories in which the Portfolio may invest. Pursuant to this strategy, the Adviser will make periodic tactical adjustments to the Portfolio’s weightings toward asset classes and asset categories that, in the Adviser’s view, offer the opportunity to enhance the Portfolio’s performance. In determining the weightings for each asset class and asset category, the Adviser will consider, among other things, momentum factors to determine the relative attractiveness of each asset class or asset category, as well as the overall level and trend of volatility in the market. Momentum is the tendency of investments to exhibit persistence in their performance. Volatility is a measure of the magnitude of changes in market or portfolio returns, without regard to the direction of those changes. When momentum deteriorates in a particular asset class or asset category, or the level of volatility in the market increases, the Adviser may reduce the Portfolio’s exposure to a particular asset class or asset category and to equity markets more generally. The Adviser reviews the Portfolio’s asset allocations at least monthly, or more frequently as needed, to consider adjusting the allocations based on, among other things, the Adviser’s evolving investment views amid changing market conditions. If the Adviser reduces the Portfolio’s exposure to equity investments in certain market environments, the Portfolio may forgo some of the returns that can be associated with periods of rising equity values. In addition, the Portfolio may invest in Underlying Portfolios and Underlying ETFs that employ derivatives (primarily options, futures contracts, forwards and swaps) for a variety of purposes, including to reduce risk, to seek enhanced returns from certain asset classes, and to leverage exposure to certain asset classes. The Adviser selects the Underlying Portfolios and Underlying ETFs in which to invest the Portfolio’s assets. The Adviser may add new Underlying Portfolios and Underlying ETFs or replace or eliminate existing Underlying Portfolios and Underlying ETFs without notice or shareholder approval. The Underlying Portfolios and Underlying ETFs have been selected to represent what the Adviser believes is a reasonable spectrum of investment options for the Portfolio. The Adviser has based the asset allocation target percentages for the Portfolio on a variety of factors, including the degree to which it believes the Underlying Portfolios and Underlying ETFs, in combination, are appropriate for the Portfolio’s investment objective. The Adviser may sell the Portfolio’s holdings for a variety of reasons, including to invest in an Underlying Portfolio or Underlying ETF that the Adviser believes offers superior investment opportunities. The Underlying ETFs are investment companies whose shares are listed and traded on U.S. stock exchanges or otherwise traded in the over-the-counter market and may be purchased and sold throughout the trading day based on their market price. Generally, each Underlying ETF seeks to track a securities index or a basket of securities that an “index provider” (such as Standard & Poor’s, Morgan Stanley Capital International (“MSCI”), or Bloomberg) selects as representative of a market, market segment, industry, sector, country or geographic region. An Underlying ETF generally holds the same stocks or bonds as the index it seeks to track (or it may hold a representative sample of such securities). Accordingly, each such Underlying ETF is designed so that its performance, before fees and expenses, will correspond closely with that of the index it seeks to track.
