The fund size and share are not equal because the net value of the fund unit is not equal to 1. Fund size = share * net value of fund unit. Therefore, when the net value of the fund unit is less than 1, the share is greater than the scale; When it is equal to 1, the share is equal to the scale; When it is greater than 1, the share is less than the scale.

The size of the fund is the total assets managed by the fund, that is, how much money is in the fund. Fund size is an important index when choosing a fund. Whether the scale is too large or too small requires careful choice.
