Briefly explain:

Raising interest rates means raising the deposit interest rate, but the interest rate of bonds is fixed at the time of bond issuance and will not change. Compared with deposits, the interest rate of bonds is relatively lower, so the value of bonds falls and bond funds will also be affected.

But there are many bond foundations that invest in bonds and stocks. If they lose money on bonds, they may earn it back on stocks, so raising interest rates is only one factor.
