The annualized rate of return refers to the rate of return obtained by holding it for one year.

For example, if you hold it for one month, the fund will get a yield of 5%, which is the yield obtained during the holding period. If the annualized rate of return is converted, it is 5%* 12=60%.

Performance benchmark means that financial institutions evaluate the closed rate of return according to the past performance of the product, and then convert it into annualized rate of return. Performance benchmark (annualized) can be understood as reference annualized rate of return, which does not represent the actual rate of return in the future.

According to different standards, securities investment funds can be divided into different types:

(1) According to whether the fund unit can be increased or redeemed, it can be divided into open-end funds and closed-end funds. Open-end funds are not traded on the market (as the case may be), but are purchased and redeemed by banks, brokers and fund companies, and the fund scale is not fixed; Closed-end funds have a fixed duration and are generally listed and traded on the stock exchange. Investors buy and sell fund shares through the secondary market.

(2) According to different organizational forms, it can be divided into corporate funds and contractual funds. A fund is established by issuing fund shares to establish an investment fund company, which is usually called a corporate fund; The establishment of fund managers, fund custodians and investors through fund contracts is usually called contractual funds. China's securities investment funds are all contractual funds.

(3) According to the different investment risks and returns, it can be divided into growth funds, income funds and balanced funds.

(4) According to different investors, it can be divided into bond funds, stock funds, money funds and hybrid funds.

The difference between open-end fund and closed-end fund;

(1) The variability of fund size is different. Closed-end funds have a definite duration (in China, the duration is not less than 5 years), 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.
