It can be considered from the following aspects: 1. Comparison of similar funds: the income of the same type of funds can be compared with each other. You can choose the same type of fund to compare and see if it outperforms the average level of similar funds. You can know the performance of similar funds by looking at fund rating websites or fund research reports published by investment institutions.

2. Historical performance of the fund: By looking at the historical performance of the fund, including long-term and short-term performance, such as the past 1, 3, 5 years and 10 years, we can see the trend and stability of the fund's historical performance.

3. Risk-return ratio: In the process of investing in funds, we need to pay attention to the risk-return ratio, which is the ratio of expected return and risk of an investment. Usually, funds with high risk-return ratio may bring higher returns, but they are also accompanied by higher risks.

4. Comprehensive consideration: In evaluating the fund, besides the fund's rate of return, it is also necessary to consider the fund manager's experience and management ability, market environment, fund fees and other factors. Considering these factors comprehensively, we can have a more comprehensive understanding of the performance of the fund.

It should be noted that past performance cannot guarantee future performance. When choosing a fund, investors should choose according to their own risk tolerance and investment objectives, invest rationally and avoid blindly following suit.

It's hard to write. Read a compliment before you go.
