Bond funds, also known as bond funds, refer to funds that specialize in investing in bonds. They pool the funds of many investors and invest in bonds to seek relatively stable returns.

Bonds are credit and debt certificates issued to investors when governments, financial institutions, industrial and commercial enterprises and other institutions directly borrow money from society to raise funds, and promise to pay interest at a certain interest rate and repay the principal according to agreed conditions.

In China, the investment objects of bond funds are mainly treasury bonds, financial bonds and corporate bonds.

Generally, bonds provide investors with fixed returns and principal repayment at maturity, with lower risks than stocks. Therefore, compared with stock funds, bond funds have the characteristics of stable returns and lower risks.
