Problem:
Assume that a speculator purchases a put option on British pounds (with a strike price of $1.50) for $.05 per unit. A pound option represents 31,250 units. Assume that at the time of the purchase, the spot rate of the pound is $1.51 and continually rises to $1.62 by the expiration date. What is the net profit or loss possible for the speculator based on the above information?
