1. At present, the mainstream selection method is based on fund PE valuation, that is, the lower the P/E ratio valuation, the more suitable it is for fixed investment;
2. Choose a large-scale fund, because the bigger the fund, the smaller the risk, and generally will not face the risk of liquidation;
3. Choose an index fund with a relatively low fund rate, that is, when choosing an index fund, you need to compare the subscription rate, selling rate, management rate, custody rate and sales service fee of the fund one by one, so as to choose an index fund with a relatively low fund rate for fixed investment;
4. With the help of online fund screening tools, we can screen out the index funds with the top ranking of 1/4 in recent 3 years, 2 years and nearly1year for fixed investment. Or you can choose the index fund with the top ranking in the fund ranking column of the fund purchase platform.
