For example, the fund you buy is based on the Shanghai and Shenzhen 300 Index. After holding it for a period of time, if the fund loses money, but the Shanghai and Shenzhen 300 index falls even more, then the investment level of the fund is not bad; If you make money, but the increase is not as big as the Shanghai and Shenzhen 300 index, it shows that although the fund has made money, its investment level is not very good.

Therefore, the relationship between fund performance benchmark and fund return rate is the relationship between target realization and actual realization. It is impossible to calculate the rate of return of the fund through the performance comparison standard of the fund.

fund yield rate

computing formula

Income = fund net value of the day × fund share ×( 1- redemption fee)-subscription amount+cash dividend.

Rate of return = income/subscription amount × 100%

Cumulative net value

The accumulated net value can not accurately reflect the fund's income, because the fund can choose cash when paying dividends, or it can choose to reinvest the dividends automatically. If you choose cash, you can also choose to buy it manually in a few days or months. Cumulative net worth is a simple reduction, which can be used as an indicator if accurate calculation is not needed.

According to the new fund information disclosure rules, in the annual report, semi-annual report and quarterly report of the fund, the fund manager must disclose the comparison between the net growth rate and the benchmark return rate of the same period, and require the fund to disclose the changes in the net value since the fund contract came into effect in a graphic way and compare them with the changes in the benchmark performance.
