Foreign Non U S Risk [Member]

Risk [Text Block]
•  
Foreign (Non‑U.S.) Risk: Investments in securities of non‑U.S. issuers may involve more risk than those of U.S. issuers. These securities may fluctuate more widely in price and may be more difficult to trade due to adverse market, economic, political, regulatory or other factors. Investments in emerging market countries such as China may involve more risk than investments in developed countries because the markets in emerging market countries are less developed and less liquid and are subject to increased economic, political, regulatory, or other uncertainties. In addition, the value of the Fund’s investments may decline because of factors such as unfavorable or unsuccessful government actions and reduction in government or central bank support.
China Single Country Risk [Member]

Risk [Text Block]
•  
China/Single Country Risk: Investments in issuers located in a particular country or geographic region typically involve more risk than investments in U.S. issuers because of particular market factors affecting that country or region, including political instability, geopolitical risks or unpredictable economic conditions. Risks of the Fund’s investments in securities of companies economically tied to China may include the volatility of the Chinese stock market; the Chinese economy’s heavy dependence on exports, which may be affected adversely by trade barriers or disputes or may decrease, sometimes significantly, when the world economy weakens; and the continuing importance of the role of the Chinese Government, which may take legal or regulatory actions that affect the contractual arrangements of a company or economic and market practices, and cause the value of the securities of an issuer held by the Fund to decrease significantly. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the
 
economy of Asian countries and a commensurately negative impact on the Fund. In addition, the Fund’s investments in companies owned or controlled directly or indirectly by the central, provincial or municipal governments of the People’s Republic of China or by the People’s Liberation Army (the military arm of the Chinese Communist Party) involve risks that political changes, social instability, regulatory uncertainty, adverse diplomatic developments, asset expropriation or nationalization, economic sanctions, trade embargos, cancellation of investors’ interests, or confiscatory taxation could adversely affect the performance of such companies and therefore investments by the Fund in those companies. China has a complex territorial dispute regarding the sovereignty of Taiwan and has made threats of invasion. Military conflict between China and Taiwan may adversely affect securities of Chinese, Taiwan-based and other issuers both in and outside the region. While the Chinese economy has grown at a rapid rate in recent years, the rate of growth has been declining, and there can be no assurance that China’s economy will continue to grow in the future. Investments in China A shares are subject to various licenses and quotas that may restrict daily trading and to additional risks that could affect liquidity compared to investments in companies in developed markets. Investments in China H shares are subject to the risk that the performance of the Hong Kong stock market may have little to no correlation to the performance of the Chinese stock market, and the Hong Kong stock market may behave differently from the Chinese stock market. Risks of investments in companies based in Hong Kong include heavy reliance on the Chinese economy, plus regional Asian and global economies such as the U.S. economy, which makes these investments vulnerable to changes in these economies.

•  
Currency Risk: Fluctuations in currency exchange rates may negatively affect the value of the Fund’s investments in equity securities denominated in foreign currencies or reduce the Fund’s returns. Emerging market currencies may be more volatile and less liquid, and subject to significantly greater risk of currency controls and convertibility restrictions, than currencies of developed countries.

•  
Depositary Receipts Risk: Investing in depositary receipts involves risks that are similar to the risks of direct investments in foreign securities. For example, investing in depositary receipts may involve risks relating to political, economic or regulatory conditions in foreign countries. In addition, the issuers of the securities underlying certain depositary receipts are under no obligation to distribute shareholder communications or pass through any voting rights with respect to the deposited securities to the holders of such receipts.
Illiquid Investments Risk [Member]

Risk [Text Block]
•  
Illiquid Investments Risk: Illiquid investments risk exists when certain investments are or become difficult to purchase or sell. Difficulty in selling such investments may result in sales at disadvantageous prices affecting the value of your investment in the Fund. Causes of illiquid investments risk may include low trading volumes and large positions. Foreign fixed-income securities may have more illiquid investments risk because secondary trading markets for these securities may be smaller and less well-developed and the securities may trade less frequently than domestic securities. Illiquid investments risk may be higher in a rising interest rate environment, when the value and liquidity of fixed-income securities generally go down.
Sector Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block]
•  
Sector Risk: The Fund may have more risk because it may invest to a significant extent in one or more particular market sectors, such as the information technology sector. To the extent it does so, market or economic factors affecting the relevant sector(s) could have a major effect on the value of the Fund’s investments.
Management Risk [Member]

•  
Management Risk: The Fund is subject to management risk because it is an actively-managed investment fund. The Adviser will apply its investment techniques and risk analyses in making investment decisions, but there is no guarantee that its techniques will produce the intended results. Some of these techniques may incorporate, or rely upon, quantitative models, but there is no guarantee that these models will generate accurate forecasts, reduce risk or otherwise perform as expected.

Risk [Text Block]
•  
Market Risk: The value of the Fund’s assets will fluctuate as the market or markets in which the Fund invests fluctuate. The value of the Fund’s investments may decline, sometimes rapidly and unpredictably, simply because of economic changes or other local, regional or global events, including public health crises (including the occurrence of a contagious disease or illness), terrorism, war, changing interest rate levels, the imposition of new or additional tariffs, or global conflicts, any of which can affect large portions of the securities markets. It includes the risk that a particular style of investing may be underperforming the market generally.
