Consider the following information (as of today) of a bond portfolio: Name Price per Face Bond Value Coupon Rate (Nominal Annual) Coupon Frequency Maturity (years) # Bonds Bond A $103 $100 10% Semi-annual 13 80 a) 12% for the calculation of the first coupon Bond B $100 $100 Annual 4 100 b) Subsequently the coupons will grow at a rate of 3% effective annual Bond C $42 $50 0% o 3.5 (three and half years) 120 A. Calculate the annual effective yield to maturity (YTM) of the portfolio. B. Using the nominal annual YTM with semiannual capitalization corresponding to the YTM calculated in the previous question and the modified duration of the portfolio, approximate the percentage change in the value of the portfolio if the required nominal annual yield decreases by 150 basis points.
