Wrong. You should be talking about closed-end funds. The opening and closing of closed-end funds is the same as the opening and closing of stocks. After paying dividends, you must be ex-dividend like a stock.

If it is an open-end fund, according to the net value of the fund, the net value after dividends may not necessarily become 1.00 yuan. And dividends are not determined by how much the fund has risen.

Supplement:

This may be the natural value return after dividends and ex-rights.
