The core idea
Floating-rate bond coupons reset periodically with a reference rate, so their income adjusts more quickly to changes in short-term rates.
What is happening underneath
That reduces the price adjustment needed to align the bond with new market rates.
How investors should read it
They can still carry meaningful credit, liquidity and spread risk.
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.
