2. Money market fund (MMF) refers to an investment fund that invests in short-term (within one year, with an average term of 120 days) securities in the money market. The assets of the Fund are mainly invested in short-term monetary instruments, such as treasury bills, commercial bills, bank time deposit certificates, bank acceptance bills, government short-term bonds, corporate bonds and other short-term securities. There is only one way for money funds to pay dividends-dividends are transferred to investment. Each money market fund is always maintained at 1 yuan. If it exceeds 1 yuan, the income will be automatically converted into fund shares on time, and you will have as many assets as you have fund shares. Other open-end funds have fixed shares and accumulated net unit value, and investors can only rely on the annual dividends of the fund to realize their income.
