Class A and Class C index funds have similar names, but the fund code and fund net value are different. Class A and Class C represent different shares of an index fund. The biggest difference between the two types of shares is the different rate structure.
The general fund subscription fee is divided into several grades according to the subscription amount, and different channels have different preferential rates for fund subscription. Generally speaking, because the sales service fee of Class C funds is accrued on a daily basis, the investment cost of Class C funds is cheaper than that of Class A funds in the short term.
