The fund can be said to have earned a poor net worth, but we should also consider the impact of dividends on the fund. Accurately speaking, the fund earns the difference of the accumulated net value, because the accumulated net value has already calculated the dividend. Except the money fund, the net value of the money fund is generally fixed at 1.
The fund will eventually get more benefits from the fund's investment products. Without the care of the fund manager, the fund will not generate any income. The change of net worth is only the final result, behind which is the credit of the fund manager.
