The fund does T, that is, the fund operates in a short term, and the profit comes out.

For example, choose an open-end fund and buy it when its net value is 1.0. Suppose the fund rose by 2% for some reason that day, that is, the net value was 1.2. At this time, investors choose to sell their shares on the same day, so the repeated operation method is that funds can only choose open-end funds to do T, and then it is best to choose funds without subscription fees, because subscription fees are calculated according to the number of times.
