What is a weakness of using only the duration measure in estimating bond price? What can we do to mitigate this problem? 1) Price from duration underestimates the actual bond price and we need to add convexity price adjustment to duration adjusted price. Price from convexity underestimates the actual bond price and we need to add convexity price adjustment to convexity adjusted price. 2) 3) Price from duration overestimates the actual bond price and we need to subtract convexity price adjustment from duration adjusted price 4) Price from convexity overestimates the actual bond price and we need to subtract convexity price adjustment from convexity adjusted price
