The fund income is updated at night because the fund mainly invests in a basket of stocks, and the fund income needs to be updated after the stock is closed, and the stock closing time is from 4 pm to 10, and the net value and income of the fund can only be determined after the stock is closed, so the fund income will be updated at night, usually around 10 on the trading day.

Fund income = (current net fund value-net fund value at the time of purchase) * fund share-fund handling fee. Fund income is determined by the investment target. When the investment target rises, the fund will rise, and at this time it will gain income. When the investment target falls, the fund will fall, and losses will occur at this time.

Attention should be paid to hybrid funds, equity funds, linked funds and LOF funds. Revenue will only be generated on trading days. Money funds and bond funds earn money every day. The fund income will be directly displayed in the investor's account, and investors do not need to calculate it manually.
