Frequently Asked Questions — Black-Scholes Options Pricing
What is the Black-Scholes model?
Black-Scholes is a mathematical model for pricing European-style options. It takes into account stock price, strike price, time to expiry, risk-free rate, and volatility to calculate the theoretical fair value of an option.
What are Options Greeks?
Greeks measure sensitivity of option price to various factors: Delta (price change sensitivity), Gamma (delta change rate), Theta (time decay per day), Vega (volatility sensitivity), Rho (interest rate sensitivity).
Is Black-Scholes accurate for Indian options?
Black-Scholes works well for index options (Nifty, Bank Nifty) but has limitations for individual stocks. It assumes constant volatility, which is not realistic. Use it as a reference, not as absolute truth.
