Bond funds have these advantages: low risk and low return. Due to the stable income and low risk of bonds, bond funds are less risky than stock funds, but their returns are not high. The cost is lower. Because bond investment management is not as complicated as stock investment management, the management fee of bond funds is relatively low. The income is stable. Investing in bonds has regular interest returns, and promises to repay the principal and interest at maturity, so the income of bond funds is relatively stable. Pay attention to current income. Bond funds mainly pursue a relatively fixed income in the current period, and lack the potential for appreciation compared with stock funds, so they are more suitable for investors who are unwilling to take too many risks and seek stable income in the current period.
