Black-Scholes Option Pricing Model
An analyst is interested in using the Black-Scholes model to value call options on the stock of Ledbetter Inc. The analyst has accumulated the following information:
The price of the stock is $33.
The strike price is $33
The option matures in 6 months (t=0.50)
The standard deviation of the stock’s returns is 0.30 and the variance is 0.09.
The risk-free rate is 10 percent.
Given this information, the analyst is then able to calculate some other necessary components of the Black-Scholes model:
d1=0.34177
d2=0.12964
N(d1)=0.63369
N(d2)=0.55155
N(d1) and N(d2), represent areas under a standard normal distribution function. Using the Black-Scholes model, what is the value of the call option?
The course text book provides the solution, but I have a question???
The solution is stated as follows:
V=P(N(d1)) -Xe(-krft) (N(d2)
V=(33.00(0.63369) – (33(0.95123)(0.55155)
V=20.91-17.31
V=$3.60
My question is how to calculate the figure (0.95123) Please explain. Thanks.
