Yes, as long as the current price of the fund is higher than the cost price, investors will gain. If the current price of the fund is lower than the cost price, the investor will lose money, and the fund profit and loss will be directly displayed on the investor's position, without the need for investors to calculate manually.

Fund income = (current fund net value-net value when buying the fund) * fund share-handling fee. The net value of the fund is determined by the investment target. Investment target rises, fund net value rises, investment target falls, and fund net value falls.
