Consider an $8\%$ coupon, $5$ year bond with a YTM of $10\%$ and a semi annual coupon payments. The bond has a regualr duration of $4\mathrm{.}180.$

If the YTM on the bond decreases to a new level of $8\%,$ what is the duration$-$approzimated percentage price change? A$.8\mathrm{.}36\%$ b$\mathrm{.}7\mathrm{.}74\%$ c$.7\mathrm{.}96\%$ d$.8\mathrm{.}04\%$ e$\mathrm{.}7\mathrm{.}60\%$

If the YTM on rhe bond decreases to a new level of $8\%$ and the bond has a convexity of $19\mathrm{.}574,$ calculate the approzimate percentage price change uaing the convexity adjustment.

A$.7\mathrm{.}57\%$

B$\mathrm{.}8\mathrm{.}93\%$

C$.7\mathrm{.}99\%$

D$\mathrm{.}8\mathrm{.}35\%$

E$\mathrm{.}8\mathrm{.}75\%$
