Bond Math Quant Interview Guide
Bond math quant interview guide for price, yield, coupon, discounting, accrued interest, duration, and practical examples.
Candidates who need clean fixed-income arithmetic and intuition.
Bond math is discounted cash-flow math
A bond price is the present value of coupon and principal cash flows. The hard part is usually using the right timing and rate convention.
Yield is a summary rate
Yield to maturity summarizes a bond price into one rate under assumptions. It is useful, but it can hide curve shape and reinvestment assumptions.
Concrete example
For a two-year annual coupon bond, discount the first coupon one year and the second coupon plus principal two years, using the specified rates.
Accrued interest changes quoted price
Bond questions may distinguish clean price from dirty price. Dirty price includes accrued interest since the last coupon date.
Common mistakes
Candidates often mix annual and semiannual conventions. Always state compounding frequency, coupon frequency, and whether rates are spot or yield measures.
