Open-end funds (LOF) are called "Listened Open-end Fund" or "open-end funds" in English, "listed open-end funds" in Chinese and * * * mutual funds abroad. In other words, after the issuance of listed open-end funds, investors can purchase and redeem fund shares at designated outlets, or buy and sell funds on exchanges. However, if investors want to sell the fund shares purchased at designated outlets, they must go through certain transfer custody procedures; Similarly, if you want to redeem the fund shares you bought online on the exchange and redeem them at designated outlets, you must also go through certain transfer custody procedures. Closed-end fund refers to the fund sponsors' restrictions on the total amount of fund units when setting up funds. After the total amount of fundraising is completed, the fund is announced to be established and closed, and no new investment will be accepted for a certain period of time. The circulation of fund shares is listed on the stock exchange, and investors must bid on the secondary market through securities brokers in the future. Closed-end funds belong to trust funds, which refers to the relationship between open-end funds and closed-end funds, which have been fixed in size before issuance and traded in the securities market within a specified period after issuance. The isomorphism of open-end fund and closed-end fund forms two basic modes of fund operation. Open-end fund refers to an investment fund whose scale is not fixed, but which can issue new shares or be redeemed by investors at any time according to market supply and demand. Closed-end fund is relative to open-end fund, which refers to the investment fund whose fund size has been determined before issuance and remains unchanged within the specified period after issuance. Open-end funds are not listed and traded, and are generally purchased and redeemed by banks. The scale of the fund is not fixed, and the fund unit can sell it to investors at any time or buy it back at the request of investors. Closed-end funds have a fixed duration, and the fund size is fixed during the duration. Generally listed on the stock exchange, investors buy and sell fund shares through the secondary market. Closed-end funds are not allowed to accept new shares and IPOs for a period of time before the new round of opening. When opening up, you can decide how much to bid or reinvest, and newcomers can also buy shares at this time. Generally, the opening time is 1 week and the closing time is 1 year. Fund is an indirect way of securities investment. By issuing fund shares, fund management companies concentrate investors' funds, which are managed by fund custodians (that is, qualified banks) and managed and used by fund managers to invest in financial instruments such as stocks and bonds, and then * * * bear the investment risks and share the benefits. According to different standards, securities investment funds can be divided into different types-according to whether the fund share can be increased or redeemed, they can be divided into open-end funds and closed-end funds. Open-end funds are not listed and traded, but are generally purchased and redeemed by banks, and the fund scale is not fixed; Closed-end funds have a fixed duration, and the fund size is fixed during the duration. Generally listed on the stock exchange, investors buy and sell fund shares through the secondary market. Open-end fund refers to an investment fund whose scale is not fixed, but which can issue new shares or be redeemed by investors at any time according to market supply and demand. Closed-end fund is relative to open-end fund, which refers to the investment fund whose fund size has been determined before issuance and remains unchanged within the specified period after issuance. The main difference between open-end funds and closed-end funds is that (1) the fund size is different. Closed-end funds have a clear duration (not less than 5 years in China), during which the issued fund shares cannot be redeemed. Although this kind of fund can be raised under special circumstances, it must meet strict legal conditions. So in general, the size of the fund is fixed. However, the fund shares issued by open-end funds can be redeemed, and investors can also buy fund shares at will during the duration of the fund, which leads to the constant change of the total amount of funds every day. In other words, it is always in an "open" state. This is the fundamental difference between closed-end funds and open-end funds. (2) There are different ways to buy and sell fund shares. When a closed-end fund is initiated, investors can subscribe to the fund management company or sales organization; When closed-end funds are listed and traded, investors can entrust brokers to buy and sell at market prices on the stock exchange. When investors invest in open-end funds, they can purchase or redeem them from fund management companies or sales organizations at any time. (3) The buying and selling prices of fund shares are formed in different ways. Because closed-end funds are listed on the exchange, their buying and selling prices are greatly influenced by the relationship between market supply and demand. When the market supply is less than the demand, the buying and selling price of the fund unit may be higher than the net asset value of each fund unit, and then the fund assets owned by investors will increase; When the market supply exceeds demand, the fund price may be lower than the net asset value of each fund unit. The transaction price of open-end funds is calculated based on the net asset value of the fund unit, which can directly reflect the level of the net asset value of the fund unit. In terms of fund transaction costs, investors have to pay a certain percentage of securities transaction tax and handling fee in addition to the price when buying and selling closed-end funds, just like buying and selling listed stocks; The related expenses (such as initial subscription fee, redemption fee, etc.) that investors of open-end funds need to pay are included in the fund price. Generally speaking, the transaction cost of closed-end funds is higher than that of open-end funds. (4) The investment strategies of funds are different. Since closed-end funds cannot be redeemed at any time, all the funds raised can be used for investment, so that fund management companies can formulate long-term investment strategies and achieve long-term business performance. On the other hand, open-end funds must keep some cash so that investors can redeem it at any time, but not all of it is used for long-term investment. Generally invest in assets with strong liquidity.
