After the fund is sold, the holding income will be reduced, because the selling income will be reflected in the accumulated income, and some selling expenses will be deducted after the fund is sold. The holding income of the fund refers to the income since the fund was bought, and the real income that investors can get also needs to be deducted from the selling expenses.

The cumulative income of the fund refers to the sum of the income of all funds (including all purchases and sales during the holding period). If some funds are still held, it is necessary to deduct the fund selling fee, which is the real income of investors.
