Generally, the rise and fall of funds are calculated by percentage. If the net value of the fund is 1 and the increase of the fund on that day is 1%, the final price of the fund is 1.0 1. If an investor holds a fund of 1 10,000 yuan, then the investor's income on that day is 1 10,000 yuan. The increase or decrease of the fund does not need to be calculated manually by investors, but will be directly displayed in the fund details, and the investor's income does not need to be calculated.

The rise and fall of the fund is determined by the investment target. When the investment target goes up, the fund goes up. At this time, investors will gain income, and the investment target will fall, so the foundation will fall. At this time, investors will lose money.
