This is relevant. Fund income is directly proportional to fund net value. The more the net value of the fund rises, the more the fund returns. The net value of the fund is the same as the stock price. The ups and downs determine whether the fund is profitable or loss. The formula for calculating the net fund value is: the income of each fund = the net fund value of the day-the net fund value at the time of subscription-subscription fee-redemption fee.

For example, the net value of fund A is 1 yuan; After a period of time, the net value of Fund A is 1.2 yuan, the subscription and redemption rates are both 1%, and the income of Fund A is1.2-1*1%-1.2 */kloc.
