ETF funds that track indices through different market indices, such as SSE Index ETF, SSE 50ETF, SSE 180ETF, and CSI 300ETF, can be purchased directly in the securities trading software like stock trading. When choosing index ETFs issued by different fund companies, we can focus on the error and synchronization of fund tracking index.
2. In addition to index ETF funds, fund companies, banks and third-party platforms also have some OTC ETF-linked funds to track the index. You can buy on the corresponding platform account without opening a stock account. Generally, the transaction cost of such funds is higher than that of ETF funds.
