Option Pricing, Greeks, and Volatility

Derivative pricing, option Greeks, volatility surface, time decay, and option-model terms.

Option Pricing, Greeks, and Volatility is the financial-instruments landing page for option pricing models, Black-Scholes, Heston, Hull-White, lattices, implied volatility, volatility smiles, volatility surfaces, and option Greeks. It keeps related terms in one branch so readers can move from a broad instrument question to the article that owns the contract evidence.

Use this page when an option-pricing input or sensitivity changes valuation, hedging, or risk interpretation. Use the parent Derivatives page when you need the broader instrument map. For an individual decision, confirm the contract, term sheet, prospectus, confirmation, exchange specification, or disclosure record before relying on the term.

Use the table below to choose the branch that matches the instrument type, payoff feature, settlement term, or risk exposure being reviewed.

Example in Use

A call option can gain value when the stock rises, but theta decay can still reduce value as expiration approaches.

What to Check

  • Underlying price, strike, time to expiration, volatility input, interest rate, dividend or carry assumption, and exercise style.
  • Delta, gamma, theta, vega, rho, lambda, model choice, calibration date, and market quote source.
  • Moneyness, volatility surface, skew, liquidity, model limitation, and hedge rebalancing assumption.
  • Effect on premium, hedge ratio, time decay, volatility exposure, and scenario loss.

Common Mistakes

  • Treating model value as a guaranteed market price.
  • Using one volatility input without checking skew, term structure, and market liquidity.
  • Reading a Greek in isolation without considering the whole position and how sensitivities change.
