About Bonds
Bonds are fixed-income securities that represent a loan made by an investor to a borrower (typically a corporation or government entity). They provide a predictable income stream and are considered lower-risk investments compared to stocks.
Bond Structure
Key Components:
- Face Value (Par Value): The amount repaid at maturity
- Coupon Rate: Annual interest rate paid to bondholders
- Coupon Payment: Periodic interest payments
- Maturity Date: When the bond principal is repaid
- Yield to Maturity: Total return if held to maturity
Bond Pricing Concepts
Premium Bonds:
Bonds trading above face value when coupon rate > market yield
Example: 5% coupon bond when market yields are 3%
Discount Bonds:
Bonds trading below face value when coupon rate < market yield
Example: 3% coupon bond when market yields are 5%
Yield to Maturity (YTM)
Yield to Maturity is the total return anticipated on a bond if the bond is held until maturity. It considers:
- All coupon payments
- Face value repayment
- Time to maturity
- Current market price
