- 1Input bond parameters: coupon, yield, maturity
- 2Calculate convexity
- 3Estimate price change accounting for both duration and convexity
Worked Examples
Инпут
Long-duration bond with high convexity
Резултат
Larger price gains in falling yields than losses in rising yields
Convexity positive for bullet bonds
Common Mistakes to Avoid
- ✕Using duration alone for large yield changes
- ✕Neglecting option-adjusted analysis for callable bonds
Frequently Asked Questions
Can convexity be negative?
Yes, for callable bonds when rates fall and issuer likely calls.
