(1) Tracked Country and Region: The level of economic development, market size, political stability, and regulatory environment of different countries and regions can significantly impact the performance of overseas and cross-border ETFs. For example, an ETF that invests in the Nasdaq index, which is an important indicator of stock market trends in the United States and globally, is particularly reflective of economic health and growth potential in the innovation and technology sectors for investors tracking technology and growth companies. Therefore, it is essential to thoroughly research the macroeconomic conditions, monetary policies, trade relations, and potential risks of the target country before investing.
