Suppose that you buy a share of stock for 52 dollars. In order to hedge your investment, you decide to also buy 2 put options and sell 1 call option on the same stock. Each of the two puts costs 6 dollars and has a strike price of 37 dollars. The call costs 7 dollars, and has a strike price of 52 dollars. Find (if it exists) the minimum possible profit for your portfolio on the exercise date. If there is no minimum, then write "None" for your answer. (Note: your portfolio contains options and a share of stock.)
Answer = dollars.
