Most funds need to deduct the subscription fee and redemption fee when buying and selling, so there is a situation that they have negative income just after buying, and the sold funds are inconsistent with the actual principal of the account. The amount of fund redemption fee is related to the holding time and total amount of the fund. The longer the fund is held, the less the redemption fee is deducted, and the more the total redemption amount of the fund is, the more the redemption fee is deducted.

After the fund is bought, it is generally not recommended to redeem it within 7 days, because the redemption rate of the fund sold within 7 days is1.5%; The redemption rate for holding for more than 7 days is 0.75%; The redemption rate for holding funds for more than 7 days and less than 30 days is 0.5%, and the redemption rate for holding funds for more than 730 days is zero. Therefore, the longer investors hold the fund, the lower the handling fee deducted when selling it, and the lowest is as low as zero. However, the transaction fee of each fund may be different, and investors can check the detailed trading rules of the fund when trading.
