Title: CHAPTER 11: BOND YIELDS AND PRICES


1
CHAPTER 11 BOND YIELDS AND PRICES
2
Chapter Summary
  • How are returns for fixed income securities
    determined?
  • Bond Characteristics
  • Bond Pricing and YTM
  • Default Risk and Ratings

3
Definition Fixed Income Security
  • A claim on a periodic income stream which is
    fixed
  • Risk is minimal
  • The easiest one is bonds

4
Bond Definitions
  • Definition of a bond issuer borrows and makes
    specified pmts to bondholder on set dates
  • Characteristics
  • Face or par value
  • Coupon rate (ie. Interest rate)
  • Zero coupon bond
  • Compounding and payments
  • Accrued Interest
  • Bond Indenture

5
Different Issuers of Bonds
  • Canada bonds
  • Provincial government bonds
  • Corporations
  • Municipalities
  • International Governments and Corporations

RISK
6
Innovative Bonds
  • Catastrophe bonds
  • Eg. Electrolux tied to earthquake in Japan
  • Asset-backed bonds
  • Eg. Walt Disney bond value is tied to success of
    movie
  • Indexed bonds
  • Eg. Coupons tied to general price index
  • Common in countries with high inflation
  • Floaters
  • Interest pmt tied to market rate (eg. Prime 2)
  • Reverse floaters
  • Coupon decreases when market rates increase

7
Summary Reminder
  • ObjectiveTo review the principles of bond
    pricing and to examine the determinants of credit
    risk.
  • Bond Characteristics
  • Bond Pricing and YTM
  • Default Risk and Ratings

8
Bond Pricing
  • PB price of the bond
  • Ct interest or coupon payments
  • T number of periods to maturity
  • r the appropriate semi-annual discount rate

9
Examples
  • Zero-coupon bonds
  • Regular bonds
  • Sold at par
  • Sold at premium
  • Sold at a discount

Bond Prices and Interest Rates
  • Prices and market interest rates have an inverse
    relationship
  • When interest rates get very high the value of
    the bond will be very low
  • When rates approach zero, the value of the bond
    approaches the sum of the cash flows

12
Prices and Interest Rates
Convex curve an increase in interest rates has a
smaller price decline than the corresponding
price decrease

13
Bond prices
  • You can look them up
  • As interest rates inc gt price falls
  • As interest rates dec gt price inc

14
Bond prices
  • Bonds selling at par
  • Price face value
  • Coupon rate market rate
  • Bonds selling at premium
  • Price gt face value
  • Coupon rate gt market rate

15
Bond prices
  • Bonds selling at discount
  • Price lt face value
  • Coupon rate lt market rate
  • Over timeprices will also move toward par value

16
Price Paths of Coupon Bonds
17
Excel Bond formulas
  • PRICE(settlement, maturity, coupon ,YTD,
    redemption date, coupons/yr)

18
BOND YIELD DEFINITIONS
  • YTM
  • Effective annual yield
  • Current yield
  • Bond equivalent uield
  • Bank discount yield
  • Yield to call
  • Realized compound yield
  • Holding period return

19
Yield to Maturity
  • Avg rate of return earned if you buy the bond
    today and hold it to maturity
  • Interest rate that makes the present value of the
    bonds payments equal to its price
  • Solve the bond price formula for r

20
Yield to Maturity Example
10 yr Maturity Coupon Rate 7 Price
950 Solve for r semiannual rate
r 3.8635
21
Excel formula for yield
  • YIELD(settlement, maturity, coupon , flat
    price, redemption as par, coupons/yr)

22
Yield Measures
  • Bond Equivalent Yield APR (simple interest)
  • Yield reported in the newspaper
  • 3.86 x 2 7.72
  • 2) Effective Annual Yield (compound interest)
  • (1.0386)2 - 1 7.88
  • 3) Current Yield (Annual Interest/Market Price)
  • 70 / 950 7.37

23
Yield to Call
  • If bond is callable, what is the expected yield
    to call date?
  • Then calculate the yield to this date.
  • Eg. N10, pmt50, FV1100, PV1150
  • Solution interest 3.99 x 2 7.98

YTM
25
Realized Yield versus YTM
  • Reinvestment Assumptions of YTM
  • YTM assumes coupons are reinvested at this rate
    until maturity
  • Realized Yield
  • Coupons are reinvested at the prevailing interest
    rates
  • Holding Period Return

26
Realized Compound Yield vs. YTM
  • Requires actual calculation of reinvestment
    income
  • Solve for the Internal Rate of Return using the
    following
  • Future Value sale price future value of
    coupons
  • Investment purchase price

27
Example Realized Yield
  • Two-year bond selling at par, 10 coupon paid
    once a year. First coupon is reinvested at 8.
    Then

28
Holding-Period Return Single Period
HPR Return over the total time period the
investor is holding the bond (ie. not annual)
  • where
  • I interest payment
  • P1 price in one period
  • P0 purchase price

29
Holding-Period Example
  • CR 8 YTM 8 N10 years
  • Semiannual Compounding P0 1000
  • In 6M the rate falls to 7 P1 1068.55

HPR 10.85 (semiannual)
30
Special characteristics of Bonds
  • Secured or unsecured
  • Registered or bearer bonds (Canada)
  • Call provision
  • Convertible provision
  • Retractable and extendible (putable) bonds
  • Traded OTC

31
Summary Reminder
  • ObjectiveTo review the principles of bond
    pricing and to examine the determinants of credit
    risk.
  • Bond Characteristics
  • Bond Pricing and YTM
  • Default Risk and Ratings

32
Default Risk and Ratings
  • Rating companies
  • Moodys Investor Service
  • Standard Poors
  • Fitch IBCA
  • Canadian Bond Rating Service (CBRS)
  • Rating Categories
  • Investment grade (BBB or above)
  • Speculative grade (ie. junk bonds, high-yield
    bonds)

33
Factors Used by Rating Companies
  • Coverage ratios
  • Leverage ratio
  • Liquidity ratios
  • Profitability ratios
  • Cash flow to debt

34
Protection Against Default
  • Bond indenture
  • Sinking funds
  • Subordination of future debt
  • Dividend restrictions
  • Collateral
