Chapter 2: Fixed Income Securities
2.1 Introduction to Fixed Income Securities
Fixed income securities are
financial instruments that provide investors with regular income payments and
return of principal at maturity. They are popular for their relatively stable
income streams compared to equity investments.
2.2 Bond Features
Bonds, a type of fixed income
security, share common features:
1. Principal: The face value or
par value of the bond, which is returned to the investor at maturity.
2. Coupon Rate: The fixed
interest rate paid periodically (usually semi-annually or annually) on the face
value of the bond.
3. Maturity Date: The date when
the issuer repays the principal amount to the bondholder.
4. Issuer: The entity
(government or corporation) that issues the bond to raise capital.
2.3 Types of Bonds
Bonds can vary based on issuer,
maturity, coupon structure, and other features:
1. Government Bonds: Issued by
governments to finance public spending. Examples include Treasury bonds and
savings bonds.
2. Corporate Bonds: Issued by
corporations to raise capital for expansion or operations. They carry varying
degrees of credit risk based on the issuer's financial health.
3. Municipal Bonds: Issued by
state or local governments to fund public projects. Interest income from
municipal bonds is often tax-exempt at the federal level.
4. Convertible Bonds: Bonds
that can be converted into a specified number of shares of the issuer's common
stock.
5. Zero-Coupon Bonds: Bonds
that do not pay periodic interest but are sold at a discount to face value. The
investor earns interest through price appreciation.
2.4 Estimating Bond Yields
Bond yields measure the return
an investor receives from holding a bond. Key yield measures include:
1. Current Yield: Annual
interest income divided by the bond's current market price.
2. Yield to Maturity (YTM): The
total return anticipated on a bond if held until maturity, considering its
current market price, coupon payments, and principal repayment.
3. Yield to Call (YTC): Yield
assuming the bond is called (redeemed) by the issuer before maturity.
2.5 Bond Valuation
Bond valuation involves
determining the fair price of a bond based on its future cash flows (coupon
payments and principal repayment) discounted at a suitable interest rate.
2.6 Types of Bond Risks
Investing in bonds carries
several risks that investors should consider:
1. Interest Rate Risk: Bond
prices are inversely related to interest rates. Rising rates decrease bond
prices, and vice versa.
2. Credit Risk: The risk of the
issuer defaulting on payments. Higher-risk bonds (e.g., junk bonds) offer
higher yields to compensate for this risk.
3. Reinvestment Risk: Risk that
future proceeds from interest payments will have to be reinvested at lower
rates.
4. Call Risk: Risk that the
issuer will call (redeem) a bond before maturity, especially when interest
rates decline.
5. Liquidity Risk: Risk that a
bond may not be easily sold or converted to cash quickly without a significant
price concession.
2.7 Default Risk and Credit Rating
Credit ratings assess the
creditworthiness of bond issuers:
- Investment Grade: Bonds rated
BBB- or higher by agencies like Moody's, S&P, or Fitch, indicating low to
moderate credit risk.
- High Yield (Junk) Bonds:
Bonds rated below investment grade (BB+ or lower), offering higher yields due
to higher default risk.
2.8 Conclusion
Fixed income securities,
particularly bonds, play a crucial role in investment portfolios by offering
stable income streams and varying degrees of risk exposure. Understanding bond
features, types, yield estimation, valuation methods, and risks such as default
and credit risk is essential for investors seeking to build diversified and
resilient investment portfolios.
