After you buy a fund, your return on investment depends on the net value of the fund. If the net worth is higher than when you applied, your investment will be profitable. If you drop to a lower cost, you will lose money. This is on the books, and the final profit will be redeemed. Many people hold investment funds for a long time, that is, they don't redeem them for a short time to keep their net value growing, and the funds will pay dividends in the profitable year.

The handling fee for purchasing and redeeming the Fund is about 1.5%. You have to consult clearly what the handling fee rate of the fund you bought is, and calculate your cost, that is, the net value at the time of purchase plus your handling fee, before you know how much the net value is above, you are profitable, and below this cost, you are losing money.
