Choose subscription, redemption, etc. After the three-year closed-end fund expires, the foundation will usually open the subscription and redemption for a period of time according to the contract. Investors can purchase and redeem during this period. Then close the fund or turn it into an open-end fund. When investors buy closed-end funds, they must understand the maturity time and redemption rules, so as to make correct decisions when they are due. If investors don't handle or handle it improperly after the maturity, asset losses may occur and investment expectations may not be met.
