Class A has a subscription fee, that is, when you buy a fund, you will have a subscription fee of 0.6% (the original discount rate is 0.8%), which will be deducted directly from the principal. 1 month, the redemption fee is very high, reaching 0.75%, that is, the fund cannot be held for an ultra-short period, otherwise the redemption fee will be very high until it is held for more than 2 years, and the redemption fee is 0.75%.
There is no subscription fee for Class B, and your subscription principal will fully purchase the fund share. The redemption fee of this kind of fund is 0.75% within one month, and it is 0 after 1 month, so there is no need to wait for 2 years. However, Class B has one more charge than Class A, that is, the sales service fee. This fee, like management fee and custody fee, is an annual fee system, which is accrued every day and deducted directly from the total assets of the fund, so you can see that the net value of Class B is always lower than that of Class A. The reason for the low is that such a sales service fee deducted by Class A is less than that of Class B. The fee is 0.4% of the annual fee.
A and b have different purposes. B is more suitable for holding funds in the short term. If it is determined that it can be held for a long time, it must be A. It is difficult to judge how many days this limit is, because the net value of the fund fluctuates and cannot be calculated in detail. Generally speaking, if you can determine that the holding time is more than 2 years, choose A, and if you are not sure, choose B.
