1, buy a class C fund.
Class C funds charge sales service fees, not subscription fees, and generally have little redemption fees. Some funds are held for 7 days, and some are free of redemption fee for 30 days. The sales service fee is charged according to the holding days. The longer they are held, the higher the charges will be. Therefore, it is more cost-effective to buy class C funds in the short term.
2. It is more cost-effective to buy on-site funds.
For similar funds, if they exist, it is more cost-effective to buy on-site funds, because on-site funds only charge commissions, which are generally three-tenths of the turnover, much lower than off-site funds.
3. It is more cost-effective to buy a fund with large fluctuations.
In the short term, investors mainly use the fluctuation of funds to sell high and suck low to earn a certain price difference. For funds with large fluctuations, the greater the spread income, while for funds with small fluctuations, the spread income earned in the short term may not be able to make up for the formalities.
