A fund that outperforms the performance benchmark is a good fund. 2. Different types of funds have different returns. 3. Look at the performance of the fund from a specific market background. 4. You can't just look at the short term, but the sustainable return is the key. Compared with the performance benchmark: the fund that can outperform the performance benchmark for a long time shows that the management ability of the fund is still relatively strong. For example, the benchmark of a fund is the yield of CSI 300. If the fund's income can outperform the Shanghai and Shenzhen 300 most of the time, then this standard has been reached. Quartile rule: this method arranges similar funds in increasing order, and then divides them into four equal parts, each of which contains about a quarter or 25% of the funds. The relative ranking of funds is divided into excellent, good, average and poor according to their positions. When looking at the ranking of funds, we must pay attention to the comparison between similar funds, and the comparability between different types is not strong.
