When the fund is sold, it can only be sold and bought in the same amount, because the income of the fund will not be reflected separately, and this income will only be calculated into the net holding value. Therefore, when investors sell the fund, they will sell the same share as when they bought it. For example, if an investor buys 100 funds with a net value of 1 yuan, the investor's net position is 100 yuan. When the fund rose to 5 yuan, the investor's net position was 500 yuan.

If investors want to sell the fund, they need to sell the fund principal with the value of 100 yuan in order to obtain the net income of 500 yuan.
