You don't understand it correctly. When the fund was first sold, its net value was 1, which is a fund 1 yuan. Later, the fund rose to 8.5 yuan through operation, with a net value of 8.5.

If it is assumed that a fund investor buys 654.38+00000 funds at the beginning of the fund sale, at the price of 654.38+0654.38+00000 yuan, that is, 654.38+00000 yuan, then the fund investor's 654.38+00000 funds are worth 85,000 yuan, that is to say, his income is 85,000 yuan.

If the fund loses money, the net value may be 0.5, so the value of a fund is 0.5 yuan, and the investor loses 5000 yuan.

I wonder if you understand my explanation.
