Oct. 31, 2025
Prospectus [Line Items]  
Risk [Text Block] Principal RisksThe Fund cannot guarantee that it will achieve its investment objective. As with any fund, the value of the Fund’s investments—and therefore, the value of Fund shares—may fluctuate. These changes may occur because of:Loss of money is a risk of investing in the Fund. An investment in the Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity securities risk – stock markets are volatile. The price of an equity security fluctuates based on changes in a company’s financial condition and overall market and economic conditions.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market risk – the risk that one or more markets in which the Fund invests will go down in value, including the possibility that the markets will go down sharply and unpredictably. This occurs due to numerous factors, including interest rates, the outlook for corporate profits, the health of the national and world economies, and the fluctuation of other securities markets around the world. These risks may be magnified if certain social, political, economic and other conditions and events (such as natural disasters, epidemics and pandemics, terrorism, conflicts, trade disputes and social unrest or rapid technological developments such as artificial intelligence) adversely interrupt the global economy.
Foreign Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign securities risk – foreign securities often are more volatile, harder to price and less liquid than U.S. securities. The prices of foreign securities may be further affected by other factors, such as changes in the exchange rates between the U.S. dollar and the currencies in which the securities are traded.
Foreign Currencies [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign currencies – foreign securities may be denominated or quoted in currencies other than the U.S. dollar. Changes in foreign currency exchange rates affect the value of the Fund’s portfolio. Generally, when the U.S. dollar rises in value against a foreign currency, a security denominated in that currency loses value because the currency is worth fewer U.S. dollars. Conversely, when the U.S. dollar decreases in value against a foreign currency, a security denominated in that currency gains value because the currency is worth more U.S. dollars.
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Emerging markets risk – emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets are 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. Since these markets are smaller than developed markets, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because the Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries are unreliable compared to developed markets. Companies in emerging market countries generally are subject to less stringent financial reporting, accounting and auditing standards than companies in more developed countries. In addition, information about such companies may be less available and reliable. Many emerging markets also have histories of political instability and abrupt changes in policies, and the ability to bring and enforce actions may be limited. Certain emerging markets also face other significant internal or external risks, including the risk of war, nationalization of assets, unexpected market closures and ethnic, religious and racial conflicts.
Frontier Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Frontier markets risk – frontier market countries generally have smaller economies and even less developed capital markets than traditional emerging market countries and, as a result, the risks of investing in emerging market countries are magnified in frontier market countries. The risk magnification is the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of the private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by countries with which frontier market countries trade; and the relatively new and unsettled securities laws in many frontier market countries.
Quantitative Analysis Strategy Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Quantitative analysis strategy risk – the success of the Fund's investment strategy depends in part on the effectiveness of the subadviser's quantitative tools for screening securities. These strategies may incorporate factors that are not predictive of a security's value. Additionally, a previously successful strategy may become outdated or inaccurate, possibly resulting in losses.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives risk – derivatives may be volatile and may involve significant risks. The underlying security, commodity, measure or other instrument on which a derivative is based, or the derivative itself, may not perform as expected. Normally derivatives involve leverage, which means that their use can magnify significantly the effect of price movements of the underlying securities or reference measures, disproportionately increasing the Fund’s losses and reducing the Fund’s opportunities for gains. Some derivatives have the potential for unlimited loss, including a loss that may be greater than the amount invested. They also present default risks if the counterparty to a derivatives contract fails to fulfill its obligations to the Fund. Certain derivatives held by the Fund may be illiquid, making it difficult to close out an unfavorable position. Finally, the Fund's use of derivatives may cause the Fund to realize higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments. Derivatives also may be more difficult to purchase, sell or value than other instruments.
Currency Exposure [Member]  
Prospectus [Line Items]  
Risk [Text Block] Currency exposure – the Fund’s investments in currency futures and forward foreign currency exchange contracts (collectively, “currency contracts”) may involve a small investment relative to the amount of risk assumed. To the extent the Fund enters into these transactions, its success will depend on the subadviser’s ability to predict market movements, and their use may have the opposite effect of that intended. Risks include potential loss due to the imposition of controls by a government on the exchange of foreign currencies, the loss of any premium paid to enter into the transaction, delivery failure, default by the other party, or inability to close out a position because the trading market becomes illiquid. Currency contracts may reduce the risk of loss from a change in the value of a currency, but they also limit any potential gains and do not protect against fluctuations in the value of the underlying security.
Futures [Member]  
Prospectus [Line Items]  
Risk [Text Block] Futures – the prices of futures contracts typically are more volatile than those of stocks and bonds. Small movements in the values of the assets or measures of underlying futures contracts can cause disproportionately larger losses to the Fund. While futures may be more liquid than other types of derivatives, they may experience periods when they are less liquid than stocks, bonds or other investments.
Forwards [Member]  
Prospectus [Line Items]  
Risk [Text Block] Forwards – using forwards can involve greater risks than if the Fund were to invest directly in the underlying securities or assets. Because forwards often involve leverage, their use can significantly magnify the effect of price movements of the underlying securities or reference measures, disproportionately increasing the Fund’s losses and reducing the Fund’s opportunities for gains. Currently there are few central exchanges or markets for forward contracts, and therefore they may be less liquid than exchange-traded instruments. If a forward counterparty fails to meet its obligations under the contract, the Fund will lose money.
Options [Member]  
Prospectus [Line Items]  
Risk [Text Block] Options – purchasing and selling options are highly specialized activities and entail greater-than-ordinary investment risks. When options are purchased over the counter, the Fund bears the risk that the counterparty that wrote the option will be unable or unwilling to perform its obligations under the option contract. The Fund's ability to close out positions in exchange-listed options depends on the existence of a liquid market. Options that expire unexercised have no value.
Country or Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Country or sector risk – if the Fund emphasizes one or more countries or economic sectors, it will be more susceptible to the financial, market or economic events affecting the particular issuers in which it invests than funds that do not emphasize particular countries or sectors.
Selection Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Selection risk – the risk that the securities selected by the Fund’s subadviser will underperform the markets, the relevant indexes or the securities selected by other funds with similar investment objectives and investment strategies.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] Loss of money is a risk of investing in the Fund.
