Problem 8 Find the current yield, YTM, and the capital gains yield for a N=10 years, c=14% annual coupon bond V=$1112.94 and has a face value of M=$1,000. INT-cM-14%*1000-140 (INT) Current Yield (CY) price of the Bond = 140/1112.94-0.1257=12.57% INT-70 V=1114.57 (2) Yield to Maturity (YTM) INT+(M-V)/N 240461000-1012.94740_120706 (M+V)/2 -0.1218=12.18% (1000+1112.94)/2 1056.47 (2) Yield to Maturity (YTM)- INT+(M-V)/N 140461000-11120472 138306 = 0.1196-11.96% (M+2V9/3 (1000+2-1112.90/3 (3) Capital Gains Yield (CGY)- YTM-CY-12.18%-12.57% -0.39%
