  4. Alternative Measures of Yield • Yield to Call • Call price replaces par • Call date replaces maturity • Holding Period Yield (actual return) • Considers actual reinvestment of coupons • Considers any change in price if the bond is held less than its maturity • Realized Compound Yield • Reinvestment rate of coupons

  5. Default Risk • Agency Assessment • Coverage ratios • Leverage ratios • Liquidity ratios • Profitability ratios • Cash flow to debt • Company’s Protection Against • Sinking funds • Subordination of future debt • Dividend restrictions • Collateral • Risk Premiums – Corporate Yields over T-bill Yields

  6. Term Structure of Interest Rates • Relationship between yields to maturity and maturity • Yield curve - a graph of the yields on bonds relative to the number of years to maturity • Usually Treasury Bonds • Have to be similar risk or other factors would be influencing yields

  7. Expectations Hypothesis Key Assumption: Bonds of different maturities are perfect substitutes Implication: Expected Return on bonds of different maturities are equal For n-period bond: yt + yt+1 + yt+2 + ... + yt+(n–1) ynt = n In words: Interest rate on long bond = average short rates expected to occur over life of long bond Numerical example: One-year interest rate over the next five years 5%, 6%, 7%, 8% and 9%: Interest rate on two-year bond: (5% + 6%)/2 = 5.5% Interest rate for five-year bond: (5% + 6% + 7% + 8% + 9%)/5 = 7% Interest rate for one to five year bonds: 5%, 5.5%, 6%, 6.5% and 7%.

  8. Liquidity Premium Theory Key Assumption: Bonds of different maturities are substitutes, but are not perfect substitutes Implication: Modifies Expectations Theory with features of Segmented Markets Theory Investors prefer short rather than long bonds  must be paid positive liquidity (term) premium, lnt, to hold long-term bonds Results in following modification of Expectations Theory yt + yet+1 + yet+2 + ... + yet+(n–1) ynt = + lnt n

  9. Relationship Between the Liquidity Premium and Expectations Theories

  10. Innovations in the Bond Market • Reverse floaters • Asset-backed bonds • Pay-in-kind bonds • Catastrophe bonds • Indexed bonds • TIPS (Treasury Inflation Protected Securities)

  11. Managing Fixed Income Securities: Basic Strategies • Active strategy • Trade on interest rate predictions • Trade on market inefficiencies • Passive strategy • Control risk • Balance risk and return

  12. Bond Pricing Relationships • Inverse relationship between price and yield • An increase in a bond’s yield to maturity results in a smaller price decline than the gain associated with a comparable decrease in yield • Long-term bonds tend to be more price sensitive than short-term bonds • As maturity increases, price sensitivity increases at a decreasing rate • Price sensitivity is inversely related to a bond’s coupon rate

  13. Duration • A measure of the effective maturity of a bond • The weighted average of the times (periods) until each payment is received, with the weights proportional to the present value of the payment • Duration is equal to maturity for zero coupon bonds • Duration of a perpetuity is (1+r)/r

  14. Duration Formula

  15. Duration FormulaAnother Perspective

  16. Workout Problem-Duration • Calculate the duration of an asset that makes nominal payments of $120 one year from now, $140 two years from now, and $160 three years from now. Assume the YTM is 10%. Calculate the duration of another asset that makes nominal payments of $160 one year from now, $140 two years from now, and $120 three years from now, also with an YTM of 10%. • Spreadsheet

  17. Duration Properties • The longer the term to maturity of a bond, everything else being equal, the greater its duration. • When interest rates rise, everything else being equal, the duration of a coupon bond falls. (convexity) • The higher the coupon rate on the bond, everything else being equal, the shorter the bond’s duration. • Duration is additive: The duration of a portfolio of securities is the weighted average of the durations of the individual securities, with the weights reflecting the proportion of the portfolio invested in each.
