The core idea
Existing fixed-rate bond prices generally fall when comparable market interest rates rise. The size of the move depends mainly on duration, convexity, credit spreads and the bond's cash-flow structure.
What is happening underneath
Short-maturity or floating-rate securities usually have less direct rate sensitivity than long-duration fixed-rate bonds.
How investors should read it
For investors who can reinvest cash flows, higher rates also create a positive future effect: new money can eventually be invested at higher yields.
The same market move can carry different information depending on which maturity, issuer and risk premium is changing. Read the question together with the underlying concepts rather than treating one price move as a universal signal.
