Study Notes
Macaulay's Duration
- Measures a bond's price sensitivity to interest rate changes (yields)
- As yields increase, price decreases
- Duration increases as Time to Maturity (TTM) increases, exposing the bond to more interest rate risk
Properties of Macaulay's Duration
- Dmac ≤ TTM
- Dmac is higher for bonds with lower coupon rates (all else equal)
- Dmac is higher for bonds with lower Yield to Maturity (YTM) (all else equal)
- Dmac is higher for bonds with higher TTM (all else equal)
Modified Duration
- Modified version of Dmac, adjusting for the bond's yield
- Represents a percentage change in bond price
- Example: Dmod of 2.23 means a 1% yield increase will decrease bond price by approximately 2.23%
Implications of Duration
- Positive relationship between duration and price sensitivity to interest rate changes
- Positive relationship between TTM and duration
- Negative relationship between coupon rate and duration
- Two bonds with same Dmod have same percentage price change sensitivity to yields
Convexity
- Measures sensitivity of a bond's duration to changes in interest rates
- Accounts for non-linear relationship between bond price and yield
- Increasing (decreasing) yields decrease (increase) duration
- Convexity provides a more accurate estimate of price changes in response to interest rate movements
- Higher convexity means more curvature and less price change when yields increase
Properties of Convexity
- Convexity is higher for bonds with lower coupon rates (all else equal)
- Convexity is higher for bonds with lower YTM (all else equal)
- Convexity is higher for bonds with higher TTM (all else equal)
Rollover Strategy
- Invest in a bond for a shorter period than investment time horizon, expecting interest rates to increase
- Roll over into a new investment with a higher return when rates increase
Riding the Yield Curve
- Invest in a bond with a longer TTM than investment time horizon
- Sell the bond before maturity, taking advantage of the upward sloping yield curve
Barbell and Bullet Strategies
- Bullet: Invest in bonds with similar maturity dates
- Barbell: Invest in low-risk, low-maturity bonds and high-risk, high-maturity bonds
- Barbell tends to be more successful due to convexity benefits
