The net value of the fund has been staying for a few days, because the net value of the fund has not been updated. If it is an open-end fund, the net value of the fund will be updated every day. If it is a closed-end fund, the net value of the fund is generally one week, and some funds may be longer.

In addition, the net value calculation of closed-end funds and development funds is also different. Closed-end funds are known market prices at the time of trading. The unit transaction price of open-end funds depends on the unknown net asset value of unit funds at the time of purchase and redemption (but it can be calculated after the market closes on the same day and announced on the next trading day).
