## Stock options pricing models

The Black-Scholes model is used to calculate a theoretical call price (ignoring dividends paid during the life of the option) using the five key determinants of an option's price: stock price, strike price, volatility, time to expiration, and short-term (risk free) interest rate. This model doesn't attempt to find an intrinsic value for the stock like the previous two valuation models. Instead, it compares the stock's price multiples to a benchmark to determine if the An option pricing model is a mathematical formula or model into which you insert the following parameters: underlying stock or index price exercise price of the option
