A stock is currently selling for $50. The stock price could go up by 10 percent or fall by 5 percent each month. The monthly risk-free interest rate is 1 percent. Calculate the price of an American put option on the stock with an exercise price of $55 and a maturity of two months. (Use the two-stage binomial method.)
A. $5.10
B. $3.96
C. $4.78
D. $1.19
Why is it A
where interest rate = monthly rate*12 = 1*12 = 12%
Time period t in years = 1/no. of months in a year = 1/12 = 0.08333
