Pure debt fund: Pure debt funds mainly invest in bonds, but it should be noted that convertible bonds are generally not invested (except for the pure debt part of convertible bonds that can be traded separately). According to the maturity of bonds, pure debt funds can be divided into short-term pure debt funds with a maturity of less than 1 year and medium-and long-term pure debt funds with a maturity of more than 1 year. The expected risk level of short-term debt funds is higher than that of money market funds, and lower than that of medium-and long-term bond funds, mixed funds and equity funds. For the debt base, the shorter the duration, the smaller the risk. This is also the reason why the short-term debt fund suddenly became popular after the income of the money fund declined for a period of time.
Hybrid bond fund: Compared with pure debt base, hybrid bond fund refers to the investment in the stock market with no more than 20% of other assets on the basis of satisfying more than 80% of fund assets invested in bonds.
Index bond funds: according to whether the index is enhanced or not, index bond funds can be divided into passive index bond funds and index enhanced bond funds. With the index layout of fund companies, the number of passive index bond funds is increasing, mainly tracking credit bond index, CDB bond index and government bond index with different maturities, while the number of index-enhanced bond funds is not much at present.
The purchase methods of bonds include: investors open accounts in securities companies, entrust securities companies to buy and sell bonds, and sign account opening contracts. Securities companies, through their representatives or agents in the stock exchange, carry out bond trading business according to the entrustment conditions.
