7 The Black-Scholes Model Black-Scholes Model Value of a stock option is a function of 6 input factors:. Current price of underlying stock.. Strike price specified in the option contract. 3. Risk-free interest rate over the life of the contract. 4. Time remaining until the option contract expires.. Price volatility of the underlying stock. The price of a call option equals: C = S N ( d) E e N ( d) C = S N ( d) E e N ( d) Where the inputs are: S = Current stock price E = Option strike price r = Risk-free interest rate T = Time remaining until option σ = Sigma, representing stock price volatility, standard deviation Black-Scholes Model Black-Scholes Models C = S N ( d) E e N ( d) Where d and d equal: d = ln ( S ) σ + r T E + σ T d = d σ T 38 Remembering put-call parity, the value of a put, given the value of a call equals: S + P = C + Ee P = C S + Ee Also, remember at : C = S E P = E S 39 The Black-Scholes Model Find the value of a six-month call option on the Microsoft with an $ The current value of a share of Microsoft is $6 The interest rate available in the U.S. is r = %. The option maturity is 6 months (half of a year). The standard deviation of the underlying asset is 3% per annum. Before we start, note that the intrinsic value of the option is $ our answer must be at least that amount. The Black-Scholes Model Assume S = $6, X = $, T = 6 months, r = %, and σ = 3%, calculate the value of a call. First calculate d and d ln( S / E) + ( r +. ) T d = σ T ln(6 /) + (. +.(.3) ). d =.3. Then d, d = d σ T = = d =.8.3. =

From a standard normal probability table, look up N(d ) =.8 and N(d ) =.74 (or use Excel s normsdist function) C = (. 8) 4 e. (. ) (. 74) = $ P = $ 8. 3 $ + $ 4e.

If growth is less than anticipated, the developer thinks he can sell the land to a country club to build a golf course on the property. The development option is a option. The golf course option is a option.
