Since fund transactions are conducted during the daytime of working days, the changes of fund prices are mainly observed during the daytime of trading days. However, after the end of the trading day and before the start of the next trading day, investors can also submit applications for subscription or redemption. These applications for subscription and redemption are usually executed at the beginning of the trading day, so the net value of the fund may be affected by these operations, thus causing fluctuations in the price of the fund.
In addition, the net value of the fund will also be affected by market factors. If the market factors are favorable, the economic data is good, and investors are in a positive mood, the net value of the fund may rise; On the other hand, if the market risk increases and investors' mood is weak, the net value of the fund may fall.
Therefore, the price change of the fund at night may be due to the influence of the purchase and redemption operation and market factors. However, it is very difficult to accurately predict the change of fund price, and the investment risk of fund has a great relationship with market fluctuation. Therefore, it is impossible to determine the possibility of fund rising at night and during the day, and multiple factors need to be fully considered.
