Black-Scholes value

The value provided by a formula for pricing tradable call options that do not pay dividends. Uses the stock price, the exercise price, the risk-free interest rate, the time to expiration, and the expected standard deviation of the stock return (also know as the stock price volatility). Developed by Fischer Black and Myron Scholes.
