Black and Scholes Model

Black Scholes Model

A model for mathematically pricing options. The model takes into account the strike price, the time until the expiration date, the price of the underlying asset, and the standard deviation of the underlying asset's return. The model assumes that the option can only be exercised on the expiration date, that it will provide a risk-free return, and that the volatility of the underlying asset will remain constant throughout the life of the contract. The calculation is slightly different for calls and puts. See also: Option Adjusted Spread, Option Pricing Curve.

Black and Scholes Model

A relatively complicated mathematical formula for valuing stock options. The Black and Scholes Model is used in options pricing to determine whether a particular option should be selling at a price other than the one at which it currently trades.

However, it has been observed from previous researches that Black and Scholes model is reasonably efficient in explaining the option prices in several countries markets (Latane and Rendleman 1976; Mac B eth and Merville 1979; Manaster and Rendleman, 1982).

The pricing efficiency of options market can be stated to be prevailing, when there is no significant deviation exists between the theoretical option prices obtained from the Black and Scholes model and the observed market prices of the options.
