What is it that the fund has no income?
1 just bought it. The fund implements T+ 1 trading, and the share is confirmed on the second trading day of the day. After the share is determined, the fund's income on the same day will be updated on the third day, so the income two days before buying the fund is invisible.
On weekends, most funds are not updated on Saturday and Sunday, and the holders can't see the income, but they will update the income on Saturday and Sunday together on Monday.
3 if you lose money or don't make money or lose money, the net value of the fund will fluctuate with the market. If the market rises actively, it will generate income. If it falls, the income or principal will be deducted. Sometimes, if you don't go up or down, you will maintain a balance, and you won't make money or lose money.
