Yes, the fund income is generally updated the next day, and the fund income is determined by the net value of the fund. The fund's net value is generally updated after the stock is closed, and the closing time of the stock is from 4 pm to 10 on the trading day, so the fund can generally see the income of the day on the second trading day.
When the net value of the fund rises, the fund gains, and when the net value of the fund falls, the fund loses.
