12. 10-12 Irwin/McGraw-hill © The McGraw-Hill Companies, Inc., 1998 Bond Prices and Yields Prices and Yields (required rates of return) have an inverse relationship When yields get very high the value of the bond will be very low When yields get very high the value of the bond will be very low When yields approach zero, the value of the bond approaches the sum of the cash flows When yields approach zero, the value of the bond approaches the sum of the cash flows

14. 10-14 Irwin/McGraw-hill © The McGraw-Hill Companies, Inc., 1998 Yield to Maturity YTM = the discount rate that makes the present value of the bond’s promised payments equal to its price. Bond is priced at $1067.95, it has a coupon rate of 9% paid semiannually, a par value of $1000, and 10 years to maturity. Find the bond’s ytm. What is the current yield? Bond is priced at $945.40, it has a coupon rate of 6% paid semiannually, a par value of $1000, and 14 years to maturity. Find the bond’s ytm. What is the current yield?

15. 10-15 Irwin/McGraw-hill © The McGraw-Hill Companies, Inc., 1998 YTM versus current yield versus coupon rate Bond selling at par Bond selling at par –coupon = YTM = current yield Bond selling at a premium Bond selling at a premium –coupon > current > YTM Bond selling at a discount Bond selling at a discount –coupon < current < YTM

16. 10-16 Irwin/McGraw-hill © The McGraw-Hill Companies, Inc., 1998 Yield to call (YTC) Similar to YTM, but use time to first call date and call price as future value. Similar to YTM, but use time to first call date and call price as future value. Bond with 15 years to maturity, par of $1000, a coupon rate of 8% (paid semiannually), price of $1025, callable in 5 years at $1080. Find YTC. Bond with 15 years to maturity, par of $1000, a coupon rate of 8% (paid semiannually), price of $1025, callable in 5 years at $1080. Find YTC.

17. 10-17 Irwin/McGraw-hill © The McGraw-Hill Companies, Inc., 1998 Realized compound yield versus yield to maturity YTM will equal the realized return over the life of the bond if all payments are reinvested at an interest rate equal to the bond’s yield. YTM will equal the realized return over the life of the bond if all payments are reinvested at an interest rate equal to the bond’s yield. –Consider a bond with 10 years to maturity, coupon rate of 9 percent paid annually, and a price of $1067.10.

18. 10-18 Irwin/McGraw-hill © The McGraw-Hill Companies, Inc., 1998 Realized compound yield (RCY) versus yield to maturity (YTM) Consider a bond with 10 years to maturity, coupon rate of 9 percent paid annually, and a price of $1067.10. Consider a bond with 10 years to maturity, coupon rate of 9 percent paid annually, and a price of $1067.10. –What is its ytm? –Realized compound yield if you reinvest at ytm? –RCY if you reinvest at 3 percent?

20. 10-20 Irwin/McGraw-hill © The McGraw-Hill Companies, Inc., 1998 Holding period return (HPR) versus YTM. Consider a bond with 10 years to maturity, coupon rate of 9 percent paid annually, and a price of $1067.10. Note: ytm = 8% Consider a bond with 10 years to maturity, coupon rate of 9 percent paid annually, and a price of $1067.10. Note: ytm = 8% Suppose you hold the bond one year and interest rates decline to 7 percent. Calculate your HPR. Suppose you hold the bond one year and interest rates decline to 7 percent. Calculate your HPR. Suppose instead that rates had risen to 9 percent. What is your HPR? Suppose instead that rates had risen to 9 percent. What is your HPR?

21. 10-21 Irwin/McGraw-hill © The McGraw-Hill Companies, Inc., 1998 Original Issue Discount (OID) Consider a 10 year Treasury strip with a yield of 5 percent and face of $10,000. Consider a 10 year Treasury strip with a yield of 5 percent and face of $10,000. –Price = $6,139.13 –After one year (yield = 5%) »P = $6,446.09 »Difference = implicit interest = $306.96 »If you sold the strip for $6,500, then you would have interest income of $306.96 and capital gain of $53.91
