Yes, investors only hold the fund after the fund share is confirmed, and the daily income of the fund will be calculated by holding the fund. If the fund buys on the same day, it needs to confirm the share on the second trading day. If the fund buys after three o'clock on the trading day, the time to confirm the share will be one day later.

Fund income is determined by the rise and fall of fund net value, and fund income = (fund net value on the current day-fund net value at the time of subscription) * fund share.
