First of all, bond funds can be selected from two aspects: investment scope and historical performance. If investors with low risk tolerance can choose pure bond funds or bond funds with low stock allocation ratio, then investors with high risk tolerance can choose bond funds with high stock allocation interest rate. Historical performance represents the performance of the fund since its establishment, and investors can choose bond funds with high historical performance.

Secondly, you can buy bond funds at one time and hold them for a long time. The income of bond funds is relatively stable, which is not suitable for fixed investment or short-term operation.
