Cumulative net growth rate refers to the percentage increase or decrease of fund net value (including dividends) over a period of time.

For example, the net value of T-day fund is X;

T+ 1 day fund net value is y.

Then the growth rate is (y-x)/X.

The growth rate can be positive or negative.

It means that the fund has gone up; A negative value indicates that the fund has fallen.
