The fund sold on the same day has income. If the fund is sold before 15:00, it shall be settled according to the net value of the day; If it is sold after 15:00, it shall be settled according to the net value of the next trading day. So no matter when investors sell, there will definitely be gains on that day.

Because the subscription and redemption of funds follow the principle of unknown price, the redemption price is based on the closing net value of the day before the trading day of 15:00, and the redemption price is based on the closing net value of the second trading day after the trading day of 15:00.
