Price behavior due to positive convexity indicates which of the following?

Positive convexity refers to the curvature of the price-yield relationship of a bond or other fixed income instrument. When an instrument exhibits positive convexity, it indicates that the price of the instrument increases at an increasing rate as interest rates decline and decreases at a decreasing rate as interest rates rise.

This behavior leads to the conclusion that prices move less dramatically with changing interest rates, as the protective feature of positive convexity dampens the extent of price fluctuations in response to interest rate movements. In scenarios where interest rates decline, the price of the bond appreciates more than it would if it exhibited only linear characteristics, while in the event of rising interest rates, the price declines less than it would with negative convexity. This property provides investors with a cushion against interest rate risk and contributes to more stable price performance compared to instruments with lower convexity.

Other options do not accurately capture the essence of positive convexity. It's not that prices become completely stable (which is overly optimistic) or unaffected by interest rates (as they are still sensitive to changes but in a moderated way). Also, the notion that prices increase more significantly when rates rise contradicts the relationship defined by convexity, as price behavior in such cases is generally moderated.
