Because the dividend income of this part of the fund is actually a part of the net value of the fund unit, the net value of the general fund will decline after dividends. In layman's terms, it is to distribute part of the income earned by investors to the holders, and the holding share has not changed, so the unit net value will decrease. If the net value of the fund falls after dividends, you can buy it. If the development prospect of the fund is good and the fund itself is good, you can buy it. If the prospect is not good, it is generally recommended not to buy it. Let's wait and see.
