I wonder what the subscription rate of your fund is?
I don't know if there is any dividend during the fund period. If there is a dividend, the net value will definitely decline, but this part of the dividend will still be increased.
So I suggest you check the fund share. If it is the present value of this part of the fund, multiply it by the latest net value. When inquiring about the share, you can directly consult the place where you buy the fund. Or register in official website, a fund company, and log in to view it.
