The current stock price of a company is $39.25, the continuous annual standard deviation is 47.00%, the exercise price of an European call on the stock is $36.00, the exercise price of an European put on the stock is $36.00, the time to maturity for both options is 0.82 years, the yield on a risk-free Treasury Bill maturing on the same date at the options is 4.23%, and the continuous dividend paid throughout the year at the rate of 2.40% / year rate.
