The rise and fall of bond funds is negatively related to the stock market. Although the rise and fall of bond funds are influenced by the bond trend, that is, when bonds rise, bond funds will rise, and when bonds fall, bond funds will fall. However, when the stock market falls, investors in the market will sell stocks and buy some bond funds with lower risks, which will push the bond funds up. On the contrary, when the stock market rises, investors in the market will pursue it.
