Cumulative net value is unit net value+past dividends. This net value is of little use, that is, it represents the total income of a fund from its birth to the present, and the comparability is not strong, because the fund was established at different times. Dividends will lead to a decline in net worth, so in this case, dividends themselves will not generate income.
The net growth rate has the concept of time period. The formula is: growth rate% = (final value-initial value)/initial value. If the growth rate has not been written for a long time, it will be compared with yesterday. In other cases, such as the recent growth rate of 1 month, such as the previous year, such as a certain year, both the initial value and the final value can be found and calculated.
