Closed-end funds have a fixed closed period, during which no transactions can be made. Investors can only wait until the fund is listed or traded after the closed period. It should be noted that some closed-end funds will be listed and traded on the stock exchange. Investors can transfer funds to the on-site market for trading and selling, or they can directly buy funds on the site to cover their positions. However, the factors affecting the rise and fall of on-site funds and off-site funds are different. Even if you make up the position, you may not be able to reduce the cost or profit.
