Investors can buy funds according to the estimated net value, which is the estimated net value of the fund on that day. Investors can decide whether to buy the fund before the close, because the transactions before 3 pm on the trading day of the fund are calculated according to the net value at the close of the trading day, so it is most appropriate to buy before 3 pm on the trading day.

Investors should pay attention to the fact that the estimated net value may deviate from the actual net value, but the deviation will not be too great. Investors are generally advised to buy when the fund falls, and the purchase cost is lower when it falls.
