In recent years, ETFs (Exchange-Traded Funds) have become the focus of investors due to their flexibility, low cost, and diversified allocation characteristics. Whether it is a long-term holding strategy or a short-term volatility grid trading strategy, ETFs can meet the needs of investors with different risk preferences. Additionally, industry rotation strategies and core-satellite strategies provide investors with more options to help them maximize returns in various market environments. As the market continues to innovate, the variety of ETF products is increasingly rich, allowing investors to flexibly allocate assets according to their own goals and achieve stable returns.
