Is the net value of 1.07 the same as that of 1 to buy a fund?

No, suppose you want to spend 10000 yuan on a fund, and the rate is 1.5%.

When the net value of a is 1, subscription share = subscription amount /( 1+ subscription rate)/net value of fund share =10000/(1+1.5%)/1= 99.

When the net value of a is 1.07, subscription share = subscription amount /( 1+ subscription rate)/net value of fund share =10000/(1+1.5%)/1.

Obviously, the lower the net value of the fund when buying, the more shares you buy with the same amount, and of course the better.
