There are two rules for fund redemption: "first in first out" and "last in first out". FIFO means that investors buy the same fund many times. When handling the redemption business, the fund company will give priority to the redemption of the fund shares that were first purchased according to the time order of subscription. Similarly, LIFO refers to the priority redemption of fund shares purchased in the future. The main difference between "first in first out" and "last in first out" is that the calculation of fund holding days and redemption rate will be different.
