Fund companies need commissions to buy and sell stocks. Stock commission is not only charged by securities companies, but also has costs. If the securities company doesn't accept commission, then the securities company is losing money, so the commission will not be exempted for the time being. It's just that the commission of fund companies buying and selling stocks may be lower than that of retail investors.

At present, the proportion of stock commission in the income of securities companies is still very high. Although the current commission level is already very low, it is still very important for securities companies.
