Generally, if you look at a fund on the fund's third-party website, there will be a fund valuation of the day. To put it simply, the fund valuation is a forecast, which predicts the net value of the fund to be announced tonight. The fund valuation changes at any time according to market conditions, so the significance of the fund valuation is to let the people have a reference on how to operate and know the trend of the fund. Fund valuation is not the true net value of the fund. The net value of the fund shall be subject to the announcement of the fund company. Fund valuation is the data released earlier than fund companies, and people can refer to it at any time.
Therefore, the basic people can operate within the trading hours of the day according to the fund valuation, but the fund share of the operation is determined by the fund net value finally announced by the fund company.
