You are attempting to value a call option with an exercise price of $140 and one year to expiration. The underlying stock pays no dividends, its current price is $140, and you believe it has a 50% chance of increasing to $160 and a 50% chance of decreasing to $120. The risk-free rate of interest is 10%. Based upon your assumptions, calculate your estimate of the the call option's value using the two-state stock price model. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Value of the call $
Current trading price=$140
It can go up =U=$160
It can go down=D=$120
Probability of going up=p=0.5
Probability of going down=1-p=0.5
Call strike price=$140(at the money)
Payoff if price goes up=(160-140)=$20
Pay off if it comes down=$0
Net expected payoff after one year=20*0.5+0= $ 10
Risk free Interest rate=10%=0.1
Present value of payoff=10/(e^0.1)= 9.048374
Call Option price= $ 9.05
