The fund’s net value growth rate.

What will not affect the fund's final return is the fund's net value growth rate.

Regardless of the fund's net worth, what determines investment income is the change in the net worth growth rate, not the level of the net worth.

Theoretically, there is no ceiling on the net value of a fund.

The level of the fund's net worth is not directly related to the room for rise or fall, but is related to the performance of the fund's portfolio.
