The current price of a stock is below.

In 1 year, the price will be Pu if the price increases and Pd if the price decreases.

The annual risk-free rate is below.

Using the binomial method, find the price of a call option on the stock that has the strike price listed below and expires in one year.

Current Stock Price, P	$17.00
Pu	$20.00
Pd	$15.00
risk-free rate	3%
Strike price	$16.00
time to expiration	1	year

5. Calculate the optimal number of shares, Ns, in our future hedge portfolio. Use the equation (Cu-Cd)/(P(u-d))

6. If the market increases at a factor of u, calculate the Portfolio payoff, Pu(Ns) and subtract Cu to obtain the net portfolio payoff.

7.If the market decreases at a factor of d, calculate the Portfolio payoff, Pd(Ns) and subtract Cd to obtain the net portfolio payoff.

8. Both net portfolio payoffs should be the same. Now find the present value (PV) of the net portfolio payoff with daily compounding. Use 365 days in a year.

N
I/Y
PMT
FV
PV	$0.00

9. Using the present value of the portfolio you have just calculated, now solve for the value of the call, Vc.

(Make sure you use the positive value of the PV.)

Use the equation PVportfolio = Ns(P) - Vc
