The net value of the fund is generally updated on the evening of the trading day, and Saturday, Sunday and national legal holidays are not trading days. Therefore, if the net value of the fund is not updated on Saturday, investors can calculate its profit and loss according to its published net value and position cost, that is, when the published net value is greater than the investor's position cost, investors will make a profit, on the contrary, when the published net value is less than the investor's position cost, investors will lose money.

At the same time, when investors buy and sell funds, it should be noted that if investors trade funds before the trading day 15:00, their shares will be calculated according to the net value announced that night, otherwise their funds will be redeemed; If investors trade funds after the trading day 15:00, they will submit them in the next transaction, and their shares will be calculated according to the net value announced that night, otherwise their funds will be redeemed.
