Hello, there are these: 1. There is a debt crisis in a company. After all, bond funds not only invest in treasury bonds, but also invest in some corporate bonds. If a company has problems and cannot pay when due, it will be equivalent to an investment loss and the bond fund will fall.

2. Buy high and sell low. The price of bond funds is not static and fluctuates. When the cost of buying by the fund manager is higher than the current price, it means a loss.

3. Interest rates rise. The rise and fall of bond prices has an inverse relationship with the rise and fall of interest rates. When interest rates rise, bond prices will fall. If the reserve requirement ratio is cut and interest rates are cut, bond prices will rise. When interest rates fall, investors will tend to buy long-term bonds with high interest rates.

yields, thereby pushing up bond prices.
