LOF Fund is an open-end fund. Investors can purchase and redeem at designated outlets or buy and sell funds on exchanges. Trading on the exchange requires a certain commission fee. Among them, the difference between Class A and Class C of LOF funds is mainly that investors charge different fees when purchasing and redeeming funds at designated outlets. LOF Fund Class A is a front-end fee-based fund, which means that investors need to charge a certain subscription and redemption fee when purchasing. LOF fund class C does not need to charge subscription fees, and redemption fees can be reduced, but the service fee will be deducted from the fund assets during the holding period.
