Buying a fund is money, not a fund share. So when redeeming, you are redeeming the number of your fund shares. The net fund value multiplied by your redemption share is the total amount of funds. Subtract the total amount of money from your investment. If it is positive, it is profit; If it is negative, it is a loss.
Redemption funds can be redeemed at the bank counter or the bank counter. Online banking redemption can be redeemed according to the process requirements.
