Options Smile Dynamics Interview Guide
Options smile dynamics interview guide covering smile, skew, sticky strike, sticky delta, stress moves, examples, and risk.
Candidates discussing skew, surface shifts, and market stress.
Smile dynamics describe how the surface moves
Options smile dynamics ask how implied volatility at different strikes changes when the underlying moves or market stress changes.
Sticky strike and sticky delta are approximations
Sticky-strike keeps implied volatility by strike fixed, while sticky-delta keeps volatility by moneyness or delta more stable.
Concrete example
If an equity index falls and downside skew steepens, a simple sticky-strike assumption may underestimate put revaluation.
Dynamics affect hedging
Delta, vega, and skew hedges can behave differently depending on how the surface moves during the underlying price change.
Common mistakes
Candidates often assume one rule is correct. Real smile dynamics vary by asset class, regime, expiry, and dealer positioning.
