A semiannual payment bond with a $1,000 par has a 7 percent quoted coupon rate, a 7 percent promised YTM, and 10 years to maturity. What is the bond's duration? If interest rates are expected to rise by one half of a percent, by how much would you expect the price to change using the modified duration equation? How much would you expect the price to change using convexity? You need to use the bond duration and convexity calculator to answer this question.
