The net value of the fund is announced by the fund company after the stock market closes, so the rise and fall of the fund on that day needs to wait until the fund company announces it at night, and the real-time rise and fall of the fund cannot be seen during trading hours.

At present, for the convenience of investors, most fund sales platforms will estimate the net value and fluctuation of the fund during trading hours according to the fund's position in the last quarter and the performance of the market index on that day, but the estimated net value is not accurate and can only be used as a reference.
