1. If an investor buys before 3 o'clock on the first day, and his selling order is submitted on the same day, the redemption amount is calculated according to the net value of that night, then the rise and fall of the fund on the second day will not affect the investment income.

2. If the investor buys after three o'clock on the first day, he submits his selling order the next day, and the redemption amount is calculated according to the net value of the next night. So the next day's ups and downs will affect investors' income, that is, the net value of the fund will rise and investors' income will increase. On the contrary, the net value of the fund will fall, and the income of investors will decrease.
