Key ideas in How Bonds Price Risk

  • Current yield measures only the annual cash coupon divided by the purchase price
  • Discount bonds generate an additional capital gain as their price gradually pulls to par
  • YTM captures both cash flow and the price convergence to par value at maturity
  • Fixed coupon rates cannot adjust upward when market interest rates climb
  • Existing bond prices drop until their effective return matches newer market issues
  • A bond trading below face value is priced at a discount to boost buyer yield
  • Zero-coupon bonds issue no periodic interest checks during their lifespan
  • All profit comes from purchasing well below par and redeeming at full par value
  • Trading at a steep discount is what enables a zero-coupon bond to produce a yield
  • Holding a solvent bond to maturity delivers the exact Yield to Maturity locked in at purchase
  • Exiting a bond position before maturity exposes the seller to fluctuating secondary market prices
  • Selling when market yields have risen forces the seller to accept a capital loss
  • Macaulay duration measures the cash-flow-weighted average time until payout.
  • Intermediate coupon checks return a portion of invested principal early.
  • Early cash payouts pull the weighted waiting time below legal maturity.
  • Modified duration estimates percentage price swing per 1% rate shift.
