Dec. 31, 2025
Volatility Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Volatility Management Risk.  Although the Subadviser attempts to adjust the Portfolio’s overall exposure to volatility, there can be no guarantee that the Subadviser will be successful in managing the Portfolio’s overall level of volatility. The Portfolio may not realize the anticipated benefits from its volatility management strategies or it may realize losses because of the investment techniques employed by the Subadviser to manage volatility, the implementation of those strategies by the Subadviser or the limitations of those strategies in times of extremely low volatility or extremely high volatility. Under certain market conditions, the use of volatility management strategies by the Subadviser may also result in less favorable performance than if such strategies had not been used. For example, if the Portfolio has reduced its overall exposure to equities to avoid losses in certain market environments, the Portfolio may forego some of the returns that can be associated with periods of rising equity values.
Model and Data Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Model and Data Risk.  When the quantitative models (“Models”) and information and data (“Data”) used in managing the Portfolio contain an error, are input or designed incorrectly, or prove to be incorrect or incomplete, any investment decisions made in reliance on the Models and Data may not produce the desired results and the Portfolio may realize losses. Models may cause the Portfolio to underperform other investment strategies and may not perform as intended in volatile markets. In addition, any hedging based on faulty Models and Data may prove to be unsuccessful. Furthermore, the success of Models that are predictive in nature is dependent largely on the accuracy and reliability of the supplied historical data. All Models are susceptible to input errors which may cause the resulting information to be incorrect.
Asset Allocation Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Asset Allocation Risk.  The Portfolio’s ability to achieve its investment objective depends upon the Subadviser’s analysis of various factors and the mix of asset classes that results from such analysis, which may prove incorrect. The particular asset allocation selected for the Portfolio may not perform as well as other asset allocations that could have been selected for the Portfolio. The Portfolio may experience losses or poor relative performance if the Subadviser allocates a significant portion of the Portfolio’s assets to an asset class that does not perform as the Subadviser anticipated, including relative to other asset classes or other subsets of asset classes. The Portfolio may underperform funds that allocate their assets differently than the Portfolio.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk.  The Portfolio will primarily invest in derivatives, such as futures and forward contracts, and swaps, to seek exposure to certain asset classes and enhance returns. To a lesser extent, the Portfolio may also invest in derivatives to “hedge” or protect its assets from an unfavorable shift in the value or rate of a reference instrument. Derivatives can be highly volatile and can significantly increase the Portfolio’s exposure to market risk, credit and counterparty risk and other risks, as well as increase transaction costs. Derivatives may be illiquid and difficult to value and can involve risks in addition to, and potentially greater than, the risks of the underlying reference instrument. Because of their complex nature, some derivatives may not perform as intended. As a result, the Portfolio may not realize the anticipated benefits from a derivative it holds or it may realize losses. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. A risk of the Portfolio’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. Government regulation of derivative instruments may limit or prevent the Portfolio from using such instruments as part of its investment strategies, which could adversely affect the Portfolio.
Leveraging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Leveraging Risk.  Derivatives and other transactions that give rise to leverage may cause the Portfolio’s performance to be more volatile than if the Portfolio had not been leveraged. Leveraging also may require that the Portfolio liquidate portfolio securities when it is not advantageous to do so to satisfy its obligations. Leveraging may expose the Portfolio to losses in excess of the amounts invested or borrowed. Leverage can create an interest expense that would lower the Portfolio’s overall returns. There can be no guarantee that a leveraging strategy will be successful.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk.  The Portfolio’s share price can fall because of, among other things, a decline in the market as a whole, deterioration in the prospects for a particular industry or company, changes in general economic conditions, such as prevailing interest rates or investor sentiment, or other factors including terrorism, war, natural disasters and the spread of infectious illness including epidemics or pandemics. In addition, unexpected political, regulatory, trade and diplomatic events within the United States and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree. Significant disruptions to the financial markets could adversely affect the liquidity and volatility of securities held by the Portfolio.
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate Risk.  The value of the Portfolio’s investments in fixed income securities may decline when prevailing interest rates rise or increase when interest rates fall. The longer a security’s maturity or duration, the greater its value will change in response to changes in interest rates. The interest earned on the Portfolio’s investments in fixed income securities may decline when prevailing interest rates fall. During periods of very low or negative interest rates, the Portfolio may be unable to maintain positive returns or pay dividends to Portfolio shareholders. Additionally, under certain market conditions in which interest rates are low or negative, the Portfolio may have a very low, or even negative yield. A low or negative yield would cause the Portfolio to lose money and the net asset value of the Portfolio’s shares to decline in certain conditions and over certain time periods. Changes in prevailing interest rates, particularly sudden changes, may also increase the level of volatility in fixed income and other markets, increase redemptions in the Portfolio’s shares and reduce the liquidity of the Portfolio’s debt securities and other income-producing holdings. Changes in interest rate levels are caused by a variety of factors, such as central bank monetary policies, inflation rates, and general economic and market conditions.
Short Position Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Short Position Risk.  The Portfolio will incur a loss from a short position if the value of the reference instrument increases after the time the Portfolio entered into the short position. Engaging in a short position may cause the Portfolio to lose more money than the actual cost of the short position and the Portfolio’s potential losses may be unlimited if the Portfolio does not own the reference instrument and it is unable to close out of the short position. Any gain from a short position will be offset in whole or in part by the transaction costs associated with the short position. Short positions generally involve a form of leverage, which can exaggerate the Portfolio’s losses.
TIPS and Inflation Linked Bonds Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] TIPS and Inflation-Linked Bonds Risk.  The value of inflation-protected securities generally fluctuates in response to changes in real interest rates, which are in turn tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates would decline, leading to an increase in the value of inflation-protected securities. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates would rise, leading to a decrease in the value of inflation-protected securities. When real interest rates are rising faster than nominal interest rates, inflation-indexed bonds, including Treasury Inflation Protected Securities, may experience greater losses than other fixed income securities with similar durations. The inflation-protected securities markets are generally much smaller and less liquid than the markets for nominal bonds from the same issuers and as such can suffer losses during times of economic stress or illiquidity.
Commodities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Commodities Risk.  Exposure to the commodities markets may subject the Portfolio to greater volatility than investments in traditional securities. The value of commodities and commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. The Portfolio’s ability to invest in commodity-linked derivative instruments may be limited by the Portfolio’s intention to qualify as a regulated investment company, and could adversely affect the Portfolio’s ability to so qualify.
Credit and Counterparty Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit and Counterparty Risk.  The value of the Portfolio’s investments may be adversely affected if a security’s credit rating is downgraded or an issuer of an investment held by the Portfolio fails to pay an obligation on a timely basis, otherwise defaults or is perceived by other investors to be less creditworthy. If a counterparty to a derivatives or other transaction with the Portfolio files for bankruptcy, becomes insolvent, or otherwise becomes unable or unwilling to honor its obligation to the Portfolio, the Portfolio may experience significant losses or delays in realizing income on or recovering collateral and may lose all or a part of the income from the transaction.
Forward and Futures Contract Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Forward and Futures Contract Risk.  The successful use of forward and futures contracts will depend upon the Subadviser’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of forward and futures contracts include (i) the imperfect correlation between the change in market value of the instruments held by the Portfolio and the price of the forward or futures contract; (ii) possible lack of a liquid market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (iii) losses caused by unanticipated market movements, which are potentially unlimited; (iv) the Subadviser’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (v) the possibility that the counterparty will default in the performance of its obligations; (vi) if the Portfolio has insufficient cash, it may have to sell securities to meet daily variation margin requirements, and the Portfolio may have to sell securities at a time when it is disadvantageous to do so; (vii) the possibility that the Portfolio may be delayed or prevented from recovering margin or other amounts deposited with a futures commission merchant or clearinghouse; (viii) the possibility that position or trading limits will preclude the Subadviser from taking positions in certain futures contracts on behalf of the Portfolio; and (ix) the risks typically associated with foreign investments to the extent the Portfolio invests in derivatives traded on markets outside the United States.
Investment Company and Exchange Traded Fund Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Investment Company and Exchange-Traded Fund Risk.  An investment in an investment company or ETF involves substantially the same risks as investing directly in the underlying securities. An investment company or ETF may not achieve its investment objective or execute its investment strategy effectively, which may adversely affect the Portfolio’s performance. The Portfolio must pay its pro rata portion of an investment company’s or ETF’s fees and expenses. Shares of a closed-end investment company or ETF may trade at a premium or discount to the net asset value of its portfolio securities.
Foreign Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Investment Risk.  Investments in foreign securities, whether direct or indirect, tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social, economic and other developments abroad, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. To the extent foreign securities are denominated in foreign currencies, their values may be adversely affected by changes in currency exchange rates. All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. To the extent the Portfolio invests in foreign sovereign debt securities, it is subject to additional risks.
Market Capitalization Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Capitalization Risk.  Investing primarily in issuers in one market capitalization category (large, medium or small) carries the risk that due to current market conditions that category will be out of favor with investors. Larger, more established companies may be unable to respond quickly to new competitive challenges or attain the high growth rate of successful smaller companies. Stocks of medium and small capitalization companies may be more volatile than those of larger companies due to, among other things, narrower product lines, more limited financial resources and fewer experienced managers. In addition, there is typically less publicly available information about small capitalization companies, and their stocks may have a more limited trading market than stocks of larger companies.
Subsidiary Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Subsidiary Risk.  By investing in the Subsidiary, the Portfolio is indirectly exposed to the risks associated with the Subsidiary’s investments. The Subsidiary is not registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Portfolio and/or the Subsidiary to operate as described in this Prospectus and could adversely affect the Portfolio. The Portfolio’s ability to invest in the Subsidiary will potentially be limited by the Portfolio’s intention to qualify as a regulated investment company, and might adversely affect the Portfolio’s ability to so qualify.
Tax Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Tax Risk.  In order to qualify for the special tax treatment accorded to a regulated investment company (“RIC”) and its shareholders under the Internal Revenue Code of 1986, the Portfolio must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Portfolio’s pursuit of its investment strategies will potentially be limited by the Portfolio’s intention to qualify for such treatment and could adversely affect the Portfolio’s ability to so qualify. The Portfolio can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Portfolio were to fail to qualify for the special tax treatment accorded to a RIC and its shareholders, and were ineligible to or were not to cure such failure within the required timeframe, the Portfolio would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Portfolio’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Portfolio could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions. Please see the Statement of Additional Information for more information.
Portfolio Turnover Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Portfolio Turnover Risk.  The investment techniques and strategies utilized by the Portfolio might result in a high degree of portfolio turnover. High portfolio turnover rates will increase the Portfolio’s transaction costs, which can adversely affect the Portfolio’s performance.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] You could lose money by investing in the Portfolio.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] An investment in the Portfolio through a Contract is not a deposit or obligation of, or guaranteed by, any bank, and is not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. Government.
Risk Nondiversified Status [Member]  
Prospectus [Line Items]  
Risk [Text Block] Non-Diversification Risk.  Because the Portfolio invests in a small number of issuers, its value will be affected to a greater extent by the performance of any one of those issuers or by any single economic, political, market or regulatory event affecting any one of those issuers than would be the value of a portfolio that invests in a larger number of issuers.
