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