Calculate modi?ed Duration of a bond that pays annual coupon at a rate of 6% and matures in 2 years. This bond has face value of 1,000 and is currently selling at a yield of 8%. Show calculations. Using just modified duration, if yield changes by 0.5%, what is the expected change in the price of the bond? Show calculations. Solving this in a calculator or at some other website that allows you to solve this kind of questions and just putting the value is not going to be an acceptable answer.
