The appropriate holding time of Class A funds should be judged according to the different charging methods of these two funds, where A stands for front-end charging, that is, subscription fee; C indicates that a sales service fee is required. According to the holding date, one day is charged.

Therefore, according to the fee collection mechanism, Class A funds are more suitable for long-term investment. As for the specific time, we use t to indicate that we need to meet a condition: T* sales service rate/365 > Subscription rate, i.e. T & gt365* subscription rate/sales service rate. It should be noted here that the sales service fee rate is annual, but the fee is charged by the day.

On the whole, Class A funds are relatively suitable for investors who intend to hold them for a long time, but both Class A and Class C funds are recommended to hold them for more than 7 days, otherwise there will usually be higher redemption fees, and the rate is about 1.5%.
