Astock is currently priced at $54. the stock will either increase or decrease by 10 percent over the next year. there is a call option on the stock with a strike price of $50 and one year until expiration. if the risk-free rate is 4 percent, what is the risk-neutral value of the call option?

Value = $6.33

Explanation:

First of all we have to find the risk neutral probability. For that we have to find the up-move and down-move factor. As it is given that the stock will go up or down by 10%, so the up-move factor is 1.1 and down-move factor is .9. To find the risk-neutral probability the formula is:

π=(1+r-d)/(u-d)

where;

d = down-move factor

u = up-move factor

r = risk free rate

Using this formula you will get the risk-neutral probability 0.7.

To calculate the value of the call option the formula is:

((π*C+)+((1-π)*C-))/(1+r)

where;

C+ = stock price if it goes up - strike price ((54*1.1)-50)=9.4

C- = Stock price if it goes down - strick price (as it goes negative so C- = 0, because the option holder won't exercise the otpion)

And (1+r) is to get the present value.

answer; i believe the correct answer is (treasury bills);
