What you are doing now is over-the-counter trading of open-end funds. The fund's net value is updated between working days 18 and 2 1. This announcement is official, but your inquiry on the bank website is not an official channel. Banks are the agency channels of funds, and funds are operated by fund management companies. So, you can check the net value of fund companies in official website on weekdays, or read it on the bank's website the next day. Generally, the net value of the bank's consignment channel is relatively slow to update. What you see is that the net value of the weekend has not been updated. In fact, it's just that the agency channel itself has not been updated. In fact, the net value came out on Friday night.

The reason why open-end funds announce their net value so late is mainly because there are fluctuations in the stock market and bond market on weekdays, and the final net value of the day should be calculated after the close. When the stock market closes, the fund company calculates the net value of the fund under the supervision of the custodian bank and then announces it. It takes several hours, so although the closing price is 15, the net announcement is generally between 18 and 2 1.

The so-called working day is the day when the stock market opens. Weekends and national holidays are not working days.

There is also a special situation, that is, the net value announcement of newly established funds is quite special. The newly established fund entered a closed period. During this period, the net value of the fund will only be published once a week, and will not be updated every working day before the normal subscription and redemption are opened.
