Blue represents the cumulative rate of return of the selected fund, and red represents the average cumulative rate of return of similar funds.

The cumulative rate of return of general funds is an index to measure whether a fund is good or not.

The cumulative rate of return of the fund records the cumulative income of the fund from its establishment to the present. Including cash dividend income and fund net value change income.

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

Yield = income/subscription amount × 100%.

However, the cumulative rate of return of the fund does not accurately reflect the real income of the fund. Because the fund can choose cash when paying dividends, it can also choose to reinvest the dividends automatically. However, as the benchmark of fund income change, it can still predict the profitability of the fund.
