As a bond fund manager, you are considering corporate bonds issued by Super Buy $($SB$).$ Each SB bond is a $4-$year bond with a par value of $$1$ million. Its interest payments are based on the following schedule: $$50,000$ in year $1,$ $$60,000$ in year $2,$ $$70,000$ in year $3,$ and $$80,000$ in year $4.$ You estimate SB$$s current interest rate is $6\%.$ What is the actual bond price change if the YTM increases by $100$ basis points?
