When the current net value of the fund is higher than the investor's position cost, it means that the investor is profitable; when the current net value of the fund is lower than the investor's position cost, it means that the investor is losing money. When investors are in a profitable state, then investors can redeem the fund to get this part of the profits.

Fund profit = (current fund net value-net value when buying the fund) * fund share-fund handling fee, and the fund profit will be directly displayed in the investor's account without manual calculation by the investor.
