Generally, dividends will be announced several working days in advance.

however, it doesn't make any sense to catch up with the purchase.

The reason is that dividends will lead to a decrease in net value. Even if you buy in advance, the net value of the fund will decrease after dividends. Although dividends are paid, the value of the fund will decrease.

For example, 1.6 yuan has been a fund, and .5 yuan pays dividends for each share. If the fluctuation of the net value on the dividend day is not considered, the net value after dividends should be 1.6-.5=1.1 yuan.

If it is in the form of cash dividend, your share will be paid according to each .5 yuan dividend, but the net fund value will become 1.1, and the share value will decrease. Left and right are equal.

The same is true for dividend reinvestment. After the dividend, the share will increase, because the dividend will directly become the fund share. But the net value drops, and it is still the same value after multiplication.

so it is meaningless to buy before the fund pays dividends.
