The difference between Fund A and Fund C lies in the different handling fees, as follows:
Sales service fee: Fund A does not charge investors sales service fee, while Fund C charges investors sales service fee.
Subscription fee: Fund A will charge subscription fee, while Fund C will not charge subscription fee.
Subscription fee: Class A funds charge subscription fee, while Class C funds do not charge subscription fee.
Redemption fee: Class A funds held for less than two years have redemption fee, Class C funds held for less than 30 days have no redemption fee, Class C funds held for more than 30 days have no redemption fee, and some of them are even exempted from redemption fee for more than 7 days.
In other words, Fund A is suitable for long-term holding, because the longer it is held, the lower the fee. If it is held for a long time, it will eventually be free, while fund C is suitable for short-term holding, because there is no redemption fee for holding fund C for more than 30 days.
