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
