Generally speaking, the core difference between bond funds A and B is the subscription fee. Generally, Class A has subscription fees, including front-end and back-end, while Class B bonds have no subscription fees. However, investors need to pay attention to the fact that Class B does not charge subscription or redemption fees, and there is an additional "sales service fee" compared with Class A, which is extracted on a daily basis.

Choose Class A or Class B bond funds according to their holding time. For example, the subscription fee for bond funds is 0.8%, and the redemption fee for holding for more than 90 days is 0; There is no redemption fee for Class B, and the sales service fee is 0.3%. Therefore, if it is a short-term investment, then it is obviously more appropriate to choose a Class B bond fund; If it is determined to be a long-term investment or a large investment, you can choose Class A. ..
