Credit risk. This point should be better understood, that is, "the risk of not repaying the principal and interest on time". If the credit risk of bonds becomes relatively large, the market will sell bonds, resulting in a sharp drop in prices. For bonds publicly issued by listed companies, investors can judge the credit risk through their financial risk indicators, including asset-liability ratio, current ratio, speed ratio and so on.

Interest rate risk. The bond price is inversely proportional to the market interest rate. Bonds usually have a fixed coupon rate. When the market interest rate drops, the relative yield of bonds will increase. At this time, the demand for bonds will increase and the price of bonds will rise. When the market interest rate rises, the bond price will fall.

Pay attention to the following points when buying bond funds:

1. Although the risk of bond funds is low, it is not without risk, and there may be principal loss.

2. Choose bond funds according to your risk preference, which has strong risk tolerance, and you can choose secondary debt base, graded debt, closed debt, etc. The risk tolerance is low, and it is best to choose pure debt or primary debt.

When the stock market bears, it is a good time to enter the bond market.

4. Monetary policy is loose. For example, it is a good time to enter the bond market when reducing RRR and cutting interest rates.

5. Bond funds can be purchased through bank counters, fund companies or formal official channels.
