It is possible that the fund is not a capital preservation product, and the principal may be lost, which needs to be borne by the investors themselves. But historically, funds are more likely to make money by long-term investment. The fund invests in a basket of stocks, and the income of the fund is determined by this basket of stocks. However, in the A-share market, the probability and expected return of holding the fund for a long time are greater, and the handling fee for holding the fund for a long time is cheaper.

It is easier for investors to gain income by choosing high-quality funds. They can choose funds from three aspects: fund manager, historical performance and maximum withdrawal. The longer the fund manager works, the better. You can also look at the performance of fund managers in managing funds. Historical performance is the income of the fund since its establishment. The higher the historical performance, the better. Exit refers to the interval from the highest to the lowest net value of the fund within a period of time. The lower the extraction value of funds, the better.
