Stock options pricing models

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
