Precautions:
Fund income is not compound interest every day, but only compound interest caused by changes in net value. If you want to enjoy the maximum compound interest effect, you can choose the dividend reinvestment method when buying funds.
For example, Xiaohe bought a fund of 100 yuan with a net value of 1 yuan. Assuming that the fund rises by 2% on the first day, the cost will become 102 yuan and the net value will become 1.02/ share the next day. If it goes up by 2% the next day, then this 2% is the net value of yesterday 1.
