Fund position yield = position yield/position cost. Fund income is the part of fund assets that exceeds their own value in the process of operation. Specifically, fund income includes dividends, bonuses, bond interest, price difference between buying and selling securities, deposit interest and other income.

In addition to monetary open-end funds, general funds are based on the net difference at the time of redemption or the difference at the time of trading to judge the income. The income of the fund is mainly reflected in the rise and fall of the net value.
