Although duration itself can never be negative, convexity can make it negative, since there are some securities, such as some mortgage-backed securities that exhibit negative convexity, meaning that the bond changes in price in the same direction as the yield changes.For example, a 5 year coupon bond might be subject to less interest rate risk than a 4 year zero coupon bond.
