CHAPTER 15

An investor purchases a stock for $38 and a put for $.50 with a strike price of $35. The
investor sells a call for $.50 with a strike price of $40. What is the maximum profit and
loss for this position? Draw the profit and loss diagram for this strategy as a function of

13. The common stock of the P.U.T.T. Corporation has been trading in a narrow price range
for the past month, and you are convinced it is going to break far out of that range in the
next three months. You do not know whether it will go up or down, however. The current
price of the stock is $100 per share, the price of a threemonth call option with an
exercise price of $100 is $10, and a put with the same expiration date and exercise price
costs $7. (L O 152)

until expiration, devise a zeronetinvestment arbitrage strategy to exploit the pricing
