AQR MS Fusion HV Fund Investment Risks - AQR MS Fusion HV Fund |
Dec. 31, 2025 |
|---|---|
| Below Investment Grade Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Below Investment Grade Securities Risk: Although bonds rated below investment grade (also known as “junk” securities) generally pay higher rates of interest than investment grade bonds, bonds rated below investment grade are high risk, speculative investments that may cause income and principal losses for the Fund. |
| China Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | China Risk: Despite economic and market reforms implemented over the last few decades, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies. Investing in China also involves risks of losses due to expropriation, nationalization, confiscation of assets and property, and the imposition of restrictions on foreign investments and on repatriation of capital invested. There is also the risk that the U.S. Government or other governments may sanction Chinese issuers or otherwise prohibit U.S. persons (such as the Fund) from investing in certain Chinese issuers which may negatively affect the liquidity and price of their securities. There can be no assurance that economic reforms implemented over the past few decades will continue or that they will be respected. |
| Common Stock Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Common Stock Risk: The Fund may invest in, or have exposure to, common stocks. Common stocks are subject to greater fluctuations in market value than certain other asset classes as a result of such factors as a company’s business performance, investor perceptions, stock market trends and general economic conditions. |
| Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Counterparty Risk: The Fund may enter into various types of derivative contracts as described below under “Derivatives Risk”. Many of these derivative contracts will be privately negotiated in the over-the-counter market. These contracts also involve exposure to credit risk, since contract performance depends in part on the financial condition of the counterparty. If a privately negotiated over-the-counter contract calls for payments by the Fund, the Fund must be prepared to make such payments when due. In addition, if a counterparty’s creditworthiness declines, the Fund may not receive payments owed under the contract, or such payments may be delayed under such circumstances and the value of agreements with such counterparty can be expected to decline, potentially resulting in losses to the Fund. |
| Credit Default Swap Agreements Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Credit Default Swap Agreements Risk: The Fund may enter into credit default swap agreements or credit default index swap agreements, and similar agreements as a “buyer” or “seller” of credit protection. Credit default swap agreements involve special risks because they may be difficult to value, are highly susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty). |
| Credit Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Credit Risk: Credit risk refers to the possibility that the issuer of a security or the issuer of the reference asset of a derivative instrument will not be able to make principal and interest payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation. Securities rated in the four highest categories (S&P Global Ratings (“S&P”) (AAA, AA, A and BBB), Fitch Ratings (“Fitch”) (AAA, AA, A and BBB) or Moody’s Investors Service, Inc. (“Moody’s”) (Aaa, Aa, A and Baa)) by the rating agencies are considered investment grade but they may also have some speculative characteristics, meaning that they carry more risk than higher rated securities and may have problems making principal and interest payments in difficult economic climates. Investment grade ratings do not guarantee that the issuer will not default on its payment obligations or that bonds will not otherwise lose value. |
| Currency Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Currency Risk: Currency risk is the risk that changes in currency exchange rates will negatively affect securities denominated in, and/or receiving revenues in, foreign currencies. The liquidity and trading value of foreign currencies could be affected by global economic factors, such as inflation, interest rate levels, and trade balances among countries, as well as the actions of sovereign governments and central banks. Adverse changes in currency exchange rates (relative to the U.S. dollar) may erode or reverse any potential gains from the Fund’s investments in securities denominated in a foreign currency or may widen existing losses. |
| Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Derivatives Risk: In general, a derivative instrument typically involves leverage, i.e., it provides exposure to potential gain or loss from a change in the level of the market price of the underlying security or currency (or a basket or index) in a notional amount that exceeds the amount of cash or assets required to establish or maintain the derivative instrument. Adverse changes in the value or level of the underlying asset or index, which the Fund may not directly own, can result in a loss to the Fund substantially greater than the amount invested in the derivative itself. The use of derivative instruments also exposes the Fund to additional risks and transaction costs. These instruments come in many varieties and have a wide range of potential risks and rewards, and may include, as further described in the section entitled “Principal Investment Strategies of the Fund,” futures contracts, forward contracts and swaps. A risk of the Fund’s use of derivatives is that the fluctuations in their values may not correlate perfectly with the overall securities markets. |
| Emerging Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Emerging Market Risk: The Fund intends to have exposure to emerging markets. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. Emerging markets generally have less stable political systems, less developed securities settlement procedures and may require the establishment of special custody arrangements. Emerging securities markets generally do not have the level of market efficiency and strict standards in accounting and securities regulation as developed markets, which could impact the Adviser's ability to evaluate these securities and/or impact Fund performance. |
| Fixed Income Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Fixed Income Securities Risk: Fixed income securities are subject to the risk that the securities could lose value because of interest rate changes. For example, bonds tend to decrease in value if interest rates rise. Fixed income securities with longer maturities sometimes offer higher yields, but are subject to greater price shifts as a result of interest rate changes than fixed income securities with shorter maturities. During periods of declining interest rates, a bond issuer may “call,” or repay, its high yielding bonds before their maturity dates. The Fund would then be forced to invest the unanticipated proceeds at lower interest rates, resulting in a decline in its income. Fixed income securities are generally subject to the risk that the issuer may be unable to make principal and interest payments when they are due. There is also the risk that the securities could lose value because of a loss of confidence in the ability of the borrower to pay back debt. |
| Foreign Investments Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Foreign Investments Risk: Foreign investments often involve special risks not present in U.S. investments that can increase the chances that the Fund will lose money. These risks include:•The Fund generally holds its foreign instruments and cash in foreign banks and securities depositories, which may be recently organized or new to the foreign custody business and may be subject to only limited or no regulatory oversight.•Changes in foreign currency exchange rates can affect the value of the Fund’s portfolio.•The economies of certain foreign markets may not compare favorably with the economy of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources and balance of payments position.•The governments of certain countries may prohibit or impose substantial restrictions on foreign investments in their capital markets or in certain industries.•Many foreign governments do not supervise and regulate stock exchanges, brokers and the sale of securities to the same extent as does the United States and may not have laws to protect investors that are comparable to U.S. securities laws.•Settlement and clearance procedures in certain foreign markets may result in delays in payment for or delivery of securities not typically associated with settlement and clearance of U.S. investments.•The regulatory, financial reporting, accounting, recordkeeping and auditing standards of foreign countries may differ, in some cases significantly, from U.S. standards. |
| Forward and Futures Contract Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Forward and Futures Contract Risk: As described in the “Principal Investment Strategies” section for each Fund, a Fund may invest in forward and/or futures contracts. The successful use of forward and futures contracts draws upon the Adviser’s skill and experience with respect to such instruments and is subject to special risk considerations. The primary risks associated with the use of forward and futures contracts, which may adversely affect the Fund’s NAV and total return, are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Adviser’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so. |
| Hedging Transactions Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Hedging Transactions Risk: The Adviser from time to time employs various hedging techniques. The success of the Fund’s hedging strategy will be subject to the Adviser’s ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or time passes, the success of the Fund’s hedging strategy will also be subject to the Adviser’s ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Adviser may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own costs (such as trading commissions and fees). |
| High Portfolio Turnover Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | High Portfolio Turnover Risk: The investment techniques and strategies utilized by the Fund, including investments made on a shorter-term basis or in derivative instruments or instruments with a maturity of one year or less at the time of acquisition, may result in frequent portfolio trading and high portfolio turnover. High portfolio turnover rates will cause the Fund to incur higher levels of brokerage fees and commissions, which may reduce performance, and may cause higher levels of current tax liability to shareholders in the Fund. |
| Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Interest Rate Risk: Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. Prices of longer term securities generally change more in response to interest rate changes than prices of shorter term securities. The Fund may lose money if short-term or long-term interest rates rise sharply or otherwise change in a manner not anticipated by the Adviser. |
| Investment in Other Investment Companies Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Investment in Other Investment Companies Risk: As with other investments, investments in other investment companies, including exchange-traded funds (“ETFs”), are subject to market and manager risk. In addition, if the Fund acquires shares of investment companies, shareholders bear both their proportionate share of expenses in the Fund (including management and advisory fees) and, indirectly, the expenses of the investment companies. The Fund may invest in money market mutual funds. An investment in a money market mutual fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although money market mutual funds that invest in U.S. Government securities seek to preserve the value of the Fund’s investment at $1.00 per share, it is possible to lose money by investing in a stable NAV money market mutual fund. Moreover, prime money market mutual funds are required to use floating NAVs that do not preserve the value of the Fund’s investment at $1.00 per share. Investments in REITs or securities with similar characteristics that pool investors’ capital to purchase or finance real estate investments also involve certain unique risks, including concentration risk (by geography or property type) and interest rate risk (i.e., in a rising interest rate environment, the stock prices of real estate-related investments may decline and the borrowing costs of these companies may increase). |
| Leverage Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Leverage Risk: As part of the Fund’s principal investment strategy, the Fund will make investments in futures contracts, forward contracts, swaps and other derivative instruments. These derivative instruments provide the economic effect of financial leverage by creating additional investment exposure to the underlying instrument, as well as the potential for greater loss. The net asset value of the Fund while employing leverage will be more volatile and sensitive to market movements. |
| Manager Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Manager Risk: If the Adviser makes poor investment decisions, it will negatively affect the Fund’s investment performance. |
| Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Market Risk: Market risk is the risk that the markets on which the Fund’s investments trade will increase or decrease in value. Prices may fluctuate widely over short or extended periods in response to company, market or economic news. Markets also tend to move in cycles, with periods of rising and falling prices. If there is a general decline in the securities and other markets, your investment in the Fund may lose value, regardless of the individual results of the securities and other instruments in which the Fund invests. |
| Mid-Cap Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Mid-Cap Securities Risk: The Fund may invest in, or have exposure to, the securities of mid-cap companies. The prices of securities of mid-cap companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large-cap companies by changes in earnings results and investor expectations or poor economic or market conditions, including those experienced during a recession. |
| Model and Data Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Model and Data Risk: Given the complexity of the investments and strategies of the Fund, the Adviser relies heavily on quantitative models and information and traditional and non-traditional data supplied or made available by third parties (“Models and Data”). Models and Data are used to construct sets of transactions and investments, to provide risk management insights, and to assist in hedging the Fund’s investments.When Models and Data prove to be incorrect or incomplete, including because data is stale, missing or unavailable, any decisions made in reliance thereon expose the Fund to potential risks. Similarly, any hedging based on faulty Models and Data may prove to be unsuccessful. Some of the models used by the Adviser for the Fund are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties or otherwise, the success of relying on such models may depend on the accuracy and reliability of the supplied historical data. The Adviser also uses machine learning, which typically has less out-of-sample evidence and is less transparent or interpretable, which could result in errors or omissions. The Fund bears the risk that the quantitative models used by the Adviser will not be successful in selecting investments or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.All models rely on correct data inputs. If incorrect data is entered into even a well-founded model, the resulting information will be incorrect. However, even if data is inputted correctly, “model prices” will often differ substantially from market prices, especially for instruments with complex characteristics, such as derivative instruments.The Adviser currently makes use of non-traditional data, also known as “alternative data” (e.g., data related to consumer transactions or other behavior, social media sentiment, and internet search and traffic data). There can be no assurance that using alternative data will result in positive performance. Alternative data is often less structured than traditional data sets and usually has less history, making it more complicated (and riskier) to incorporate into quantitative models. Alternative data providers often have less robust information technology infrastructure, which can result in data sets being suspended, delayed, or otherwise unavailable. In addition, as regulators have increased scrutiny of the use of alternative data in making investment decisions, the changing regulatory landscape could result in legal, regulatory, financial and/or reputational risk.The Fund is unlikely to be successful unless the assumptions underlying the models are realistic and either remain realistic and relevant in the future or are adjusted to account for changes in the overall market environment. If such assumptions are inaccurate or become inaccurate and are not promptly adjusted, it is likely that profitable trading signals will not be generated, and major losses may result. The Adviser, in its sole discretion, will continue to test, evaluate and add new models, which may result in the modification of existing models from time to time. There can be no assurance that model modifications will enable the Fund to achieve its investment objective. |
| Momentum Style Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Momentum Style Risk: Investing in or having exposure to securities with positive momentum entails investing in securities that have had above-average recent returns. These securities may be more volatile than a broad cross-section of securities. In addition, there may be periods during which the investment performance of the Fund while using a momentum strategy may suffer. |
| Repurchase Agreements Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Repurchase Agreements Risk: The Fund may invest in repurchase agreements. When entering into a repurchase agreement, the Fund essentially makes a short-term loan to a qualified bank or broker-dealer. The Fund buys securities that the seller has agreed to buy back at a specified time and at a set price that includes interest. There is a risk that the seller will be unable to buy back the securities at the time required and the Fund could experience delays in recovering amounts owed to it. |
| Reverse Repurchase Agreements Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Reverse Repurchase Agreements Risk: Reverse repurchase agreements involve the sale of securities held by the Fund with an agreement to repurchase the securities at an agreed-upon price, date and interest payment. Reverse repurchase agreements involve the risk that the other party may fail to return the securities in a timely manner or at all. The Fund could lose money if it is unable to recover the securities and the value of the collateral held by the Fund, including the value of the investments made with cash collateral, is less than the value of securities. These events could also trigger adverse tax consequences to the Fund. Furthermore, reverse repurchase agreements involve the risks that (i) the interest income earned in the investment of the proceeds will be less than the interest expense, (ii) the market value of the securities retained in lieu of sale by the Fund may decline below the price of the securities the Fund has sold but is obligated to repurchase, and (iii) the market value of the securities sold will decline below the price at which the Fund is required to repurchase them. In addition, the use of reverse repurchase agreements may be regarded as leveraging. |
| Risk Associated with Use of AI Tools Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Risk Associated with Use of AI Tools: In line with advances in computing technology and data analytics, there has been an increasing trend towards utilizing machine learning, natural language processing, artificial generative intelligence, artificial neural networks, artificial narrow intelligence, or similar tools, models and systems generally referred to as "artificial intelligence" (collectively, "AI Tools") as part of portfolio management, trading, portfolio risk management and other applications in the investment management processes used by various market participants. The Adviser currently utilizes machine learning, natural language processing, and other AI Tools in connection with, and in support of, certain of its investment management activities, and may use other AI Tools in the future. In addition, certain vendors, service providers and counterparties, including third-party data or research providers, may use AI Tools or provide AI Tools to the Adviser. Many AI Tools may be subject to one or more undetected errors, defects or security vulnerabilities. When using AI Tools, the Adviser often has limited or no visibility over the data used to train or the technology used to create these AI Tools, as well as the accuracy and completeness of such AI Tools, and there is a risk that any particular output will be unreliable. Any errors, defects or security vulnerabilities discovered after AI Tools are in widespread operation could result in substantial loss of revenues or assets, or material liabilities, reputational risks or sanctions. |
| Short Sale Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Short Sale Risk: The Fund may take a short position in a derivative instrument, such as a future, forward or swap. A short position in a derivative instrument involves the risk of a theoretically unlimited increase in the value of the underlying instrument, which could cause the Fund to suffer a (potentially unlimited) loss. Short sales also involve transaction and financing costs that will reduce potential Fund gains and increase potential Fund losses. |
| Small-Cap Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Small-Cap Securities Risk: Investments in or exposure to the securities of companies with smaller market capitalizations involve higher risks in some respects than do investments in securities of larger companies. For example, prices of such securities are often more volatile than prices of large capitalization securities. In addition, due to thin trading in some such securities, an investment in these securities may be less liquid (i.e., harder to sell) than that of larger capitalization securities. Smaller capitalization companies also fail more often than larger companies and may have more limited management and financial resources than larger companies. |
| Sovereign Debt Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Sovereign Debt Risk: The Fund may invest in, or have exposure to, sovereign debt instruments. These investments are subject to the risk that a governmental entity may delay or refuse to pay interest or repay principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of the governmental entity’s debt position in relation to the economy or the failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected. |
| Swap Agreements Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Swap Agreements Risk: Swap agreements involve the risk that the party with whom the Fund has entered into the swap will default on its obligation to pay the Fund. Additionally, certain unexpected market events or significant adverse market movements could result in the Fund not holding enough assets to be able to meet its obligations under the agreement. Such occurrences may negatively impact the Fund’s ability to implement its principal investment strategies and could result in losses to the Fund. |
| Tax Aware Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Tax Aware Risk: When employing tax-aware strategies, the performance of the Fund may deviate from that of funds that invest without any regard to after-tax returns. The Fund's tax-aware investment strategy may include active management with the intent of minimizing the amount of realized gains from the sale of securities; however, market conditions may limit the Fund's ability to execute such strategy. Although, when employing tax-aware strategies, the Fund expects that a smaller portion of its total return will consist of taxable distributions to shareholders as compared to funds that invest without any regard to after-tax returns, there can be no assurance about the size of taxable distributions to shareholders. The tax treatment of investments may be adversely affected by future tax legislation, U.S. Treasury regulations, and/or any other guidance issued by the Internal Revenue Service, including any developments that could affect the character, timing, and/or amount of taxable income or gains attributable to an account.The Fund may seek to invest in lower-yielding securities and/or stocks that pay dividends that would qualify for favorable federal tax treatment provided certain holding periods and other conditions are satisfied by the Fund. The Fund may invest a portion of its assets in stocks and other securities that generate income not eligible for taxation at preferential capital gains or dividend rates. |
| TIPS and Inflation-Linked Bonds Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Treasury Inflation-Protected Securities 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 might 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 might rise, leading to a decrease in the value of inflation-protected securities. If the Fund purchases inflation-protected securities in the secondary market whose principal values have been adjusted upward due to inflation since issuance, the Fund may experience a loss if there is a subsequent period of deflation. The inflation-protected securities markets are generally much smaller and less liquid than the nominal bonds from the same issuers and as such can suffer losses during times of economic stress or illiquidity. |
| U.S. Government Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | U.S. Government Securities Risk: Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Obligations of U.S. Government agencies and authorities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. Government. No assurance can be given that the U.S. Government will provide financial support to its agencies and authorities if it is not obligated by law to do so. Certain of the government agency securities the Fund may purchase are backed only by the credit of the government agency and not by full faith and credit of the United States. |
| Value Style Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Value Style Risk: Investing in or having exposure to “value” securities presents the risk that the securities may never reach what the Adviser believes are their full market values, either because the market fails to recognize what the Adviser considers to be the security’s true value or because the Adviser misjudged that value. In addition, there may be periods during which the investment performance of the Fund while using a value strategy may suffer. |
| Volatility Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Volatility Risk: The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund’s net asset value per share to experience significant increases or declines in value over short periods of time, however, all investments, long- or short-term, are subject to risk of loss. |
| Volatility Futures Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Volatility Futures Risk: The Fund may take long and short positions in volatility index futures. A volatility index generally attempts to reflect the projected future volatility of a specific market index by calculating the average price of listed options on the specific market index. The prices of options on market indices have tended to increase during periods of heightened volatility in the underlying market and decrease during periods of greater stability in the underlying market, which would result in increases or decreases, respectively, in the level of the volatility index. Investments in volatility index futures are subject to the risk that the Fund is incorrect in its forecast of volatility for the underlying index, and may have the potential for unlimited loss. |
| Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. |
