Graph the value of your portfolio as a function of the relevant stock price. Graph for stock prices between 50 and 100.

You own (are long) a call with an exercise price of 70 and a put at 64.

You are short a call at 90, and long a put at 75.

Short a call at 85, long a put at 89, and long one share of the stock.

Long a call at 75, short a put at 75, short a share of stock.

(1) Please use binomial option pricing model to derive the value of a one-year put option.
The current share price is ?0 = 100 and exercise price ? = 110. The T-bill rate is ? = 10% per
year and annual standard deviation is 20%.
(2) Use the Black-Scholes formula to find the value of the same option in the previous
problem and compare the difference between these two types of methods.
