Myles Houck holds 600 shares of Lubbock Gas and Light. He bought the stock several years ago at $48.50, and the shares are now trading at $75. Myles is concerned that the market is beginning to soften. He doesn't want to sell the stock, but he would like to be able to protect the profit he's made. He decides to hedge his position by buying six puts (1 put = 100 shares) on Lubbock G&L. The three-month puts carry a strike price of $75 and are currently trading at $2.50.

a. How much profit or loss will Myles make on this deal if the price of Lubbock G&L does indeed drop to $60 a share by the expiration date on the puts?

b. How would he do if the stock kept going up in price and reached $90 a share by the expiration date?
