Buffelhead’s stock price is $220 and could halve or double in each six–month period (equivalent to a standard deviation of 98%). Suppose that you own a one–year American put option on Buffelhead stock with an exercise price of $220. The interest rate is 20% a year.
(a) Calculate the value of the put.
(b) Now compare the value with that of an equivalent European put
option.
