Emerging Economies Fund Investment Risks - Emerging Economies Fund
May 31, 2026
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk. The investment style or strategy used by a subadviser may fail to produce the intended result. A subadviser’s assessment of a particular security or company may prove incorrect, resulting in losses or underperformance.
Foreign Investment Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Foreign Investment Risk. Investment in foreign securities involves risks due to several factors, such as illiquidity, the lack of public information, changes in the exchange rates between foreign currencies and the U.S. dollar, unfavorable political, social and legal developments, or economic and financial instability. Foreign companies are not subject to the U.S. accounting and financial reporting standards and may have riskier settlement procedures. U.S. investments that are denominated in foreign currencies or that are traded in foreign markets, or securities of U.S. companies that have significant foreign operations may be subject to foreign investment risk.
Emerging Markets Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Emerging Markets Risk. In addition to the risks associated with investments in foreign securities, emerging market securities are subject to additional risks, which cause these securities generally to be more volatile than securities of issuers located in developed countries.
Currency Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Currency Risk. Because the Fund’s foreign investments are generally held in foreign currencies, the Fund could experience gains or losses based solely on changes in the exchange rate between foreign currencies and the U.S. dollar. Such gains or losses may be substantial.
Geographic Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Geographic Risk. If the Fund invests a significant portion of its assets in issuers located in a single country, a limited number of countries, or a particular geographic region, it assumes the risk that economic, political and social conditions in those countries or that region may have a significant impact on its investment performance.
Equity Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Equity Securities Risk. The Fund invests principally in equity securities and is the subject to the risk that stock prices will fall and may underperform other asset classes. Individual stock prices fluctuate from day-to-day and may decline significantly. The prices of individual stocks may be negatively affected by poor company results or other factors affecting individual prices, as well as industry and/or economic trends and developments affecting industries or the securities market as a whole.
Preferred Stock Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Preferred Stock Risk. Unlike common stock, preferred stock generally pays a fixed dividend from a company’s earnings and may have a preference over common stock on the distribution of a company’s assets in the event of bankruptcy or liquidation. Preferred stockholders’ liquidation rights are subordinate to the company’s debt holders and creditors. If interest rates rise, the fixed dividend on preferred stocks may be less attractive and the price of preferred stocks may decline. Preferred stockholders typically do not have voting rights.
Depositary Receipts Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Depositary Receipts Risk.Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. Depositary receipts may or may not be jointly sponsored by the underlying issuer. The issuers of unsponsored depositary receipts are not obligated to disclose information that is considered material in the United States. Therefore, there may be less information available regarding the issuers and there may not be a correlation between such information and the market value of the depositary receipts. Certain depositary receipts are not listed on an exchange and therefore may be considered to be illiquid securities.
Convertible Securities Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Convertible Securities Risk. Convertible security values may be affected by market interest rates, issuer defaults and underlying common stock values; security values may fall if market interest rates rise and rise if market interest rates fall. Additionally, an issuer may have the right to buy back the securities at a time unfavorable to the Fund.
IPO Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] IPO Risk. A Fund’s purchase of shares issued as part of, or a short period after a company’s initial public offering (“IPO”) exposes it to risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. The market for IPO issuers has been volatile, and share prices of newly-public companies have fluctuated in significant amounts over short periods of time.
Model Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Model Risk. The risk that the asset allocation model fails to produce the optimal allocation.
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk. The prices of derivatives may move in unexpected ways due to the use of leverage and other factors and may result in increased volatility or losses. The Fund may not be able to terminate or sell derivative positions, and a liquid secondary market may not always exist for derivative positions.
Hedging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Hedging Risk. A hedge is an investment made in order to reduce the risk of adverse price movements in a currency or other investment by taking an offsetting position (often through a derivative instrument, such as an option or forward contract). While hedging strategies can be very useful and inexpensive ways of reducing risk, they are sometimes ineffective due to unexpected changes in the market. Hedging also involves the risk that changes in the value of the related security will not match those of the instruments being hedged as expected, in which case any losses on the instruments being hedged may not be reduced.
Quantitative Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Quantitative Investing Risk. The value of securities selected using quantitative analysis can react differently to issuer, political, market, and economic developments from the market as a whole or securities selected using only fundamental analysis. The factors used in quantitative analysis and the weight placed on those factors may not be predictive of a security’s value. In addition, factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model.
Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Sector Risk. Companies with similar characteristics may be grouped together in broad categories called sectors. Sector risk is the risk that securities of companies within specific sectors of the economy can perform differently than the overall market. This may be due to changes in such things as the regulatory or competitive environment or to changes in investor perceptions regarding a sector. Because the Fund may allocate relatively more assets to certain sectors than others, the Fund’s performance may be more susceptible to any developments which affect those sectors emphasized by the Fund.
Technology Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Technology Sector Risk. Technology stocks historically have experienced unusually wide price swings. Earnings disappointments and intense competition for market share can result in sharp declines in the prices of technology stocks.
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk. The Fund’s share price can fall because of weakness in the broad market, a particular industry, or specific holdings or due to adverse social, political or economic developments here or abroad, changes in investor psychology, technological disruptions, or heavy institutional selling and other conditions or events (including, for example, military confrontations, war, terrorism, trade wars, disease/virus outbreaks and epidemics). The prices of individual securities may fluctuate, sometimes dramatically, from day to day. The prices of stocks and other equity securities tend to be more volatile than those of fixed-income securities.
Securities Lending Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Securities Lending Risk. Engaging in securities lending could increase the market and credit risk for Fund investments. The Fund may lose money if it does not recover borrowed securities, the value of the collateral falls, or the value of investments made with cash collateral declines. The Fund’s loans will be collateralized by securities issued or guaranteed by the U.S. Government or its agencies and instrumentalities, which subjects the Fund to the credit risk of the U.S. Government or the issuing federal agency or instrumentality. If the value of either the cash collateral or the Fund’s investments of the cash collateral falls below the amount owed to a borrower, the Fund also may incur losses that exceed the amount it earned on lending the security. Securities lending also involves the risks of delay in receiving additional collateral or possible loss of rights in the collateral if the borrower fails. Another risk of securities lending is the risk that the loaned portfolio securities may not be available to the Fund on a timely basis and the Fund may therefore lose the opportunity to sell the securities at a desirable price.
Risk Lose Money [Member]  
Prospectus [Line Items]  
Risk [Text Block] If the value of the assets of the Fund goes down, you could lose money.
Risk Not Insured Depository Institution [Member]  
Prospectus [Line Items]  
Risk [Text Block] Shares of the Fund are not bank deposits and are not guaranteed or insured by any bank, government entity or the Federal Deposit Insurance Corporation.
