The income calculation method of currency funds is different from that of general open-end funds. Fund companies usually announce the amount of income realized per 10,000 fund units on that day, which is the income of 10,000 fund units. It should be noted that the income of 10,000 fund units is different from the cumulative income of 10,000 units. When buying a currency fund, you should look at the income of 10,000 fund units.
