Wechat daily fund income = (net fund value at the close of the previous trading day-net fund value at the close of that day) * fund share handling fee. The fund income will be directly displayed in the investor's account, and investors do not need to calculate it manually. The income generated by the fund on the same day will be updated the next day.

Fund returns are determined by investment targets, such as stock funds, which mainly invest in a basket of stocks. The rise and fall of the fund is determined by this basket of stocks. Investment stocks go up, funds go up, investors make profits, investment stocks go down, and funds go down, resulting in losses for investors.
