Bond Yields and Prices

Ex. Yield on 8% 5 year bond selling at par has duration* of 4.31 years rates go to 71/2%. ΔP/P = - 4.31* (-.005) = .0216 =2.16%. Convexity. If you have large yield changes then modified duration becomes less accurate. Duration equation assumes a linear relationship between price and yield ................
