If the fund is held for more than one year, it is recommended to buy share A. The longer the holding period, the more cost-effective it is to buy share A. Although there is no subscription fee for share C, there is a sales service fee charged every year.

A share is purchased for a subscription fee, but there is no sales service fee. So the longer you hold it, the better it is. And after a certain number of years of holding, there is no redemption fee. Therefore, if investors are sure that they are long-term investors, it is better to buy share A.
