Net fund value-net asset value. The total asset value of the assets owned by the fund is calculated according to the market closing price of each trading day. After deducting the costs and expenses of the fund on that day, the net asset value of the fund on that day is obtained. Divided by the total number of units issued by the fund on that day, it is the market value of each fund-the value of listed funds in the stock market, which changes at any time. Generally speaking, the net value determines the market value.
