The decrease of fund holding income is due to the decrease of fund net value, which is determined by fund net value. When the fund's net value rises, investors gain, and when the fund's net value falls, investors lose.

Fund holding income refers to the total income of the fund since it was held. After the fund is sold, the holding income of the fund will be included in the accumulated income, and the holding income is the income without deducting the selling expenses.
