Trader thinks DAL can trade through its 52 Week High

Delta Air Lines, Inc. provides scheduled air transportation for passengers and cargo worldwide. Today a trader bought over 2,000 5.9.2014 37 Calls for $.74. This gives the buyer of the Calls, the right but not obligation to buy 200,000 shares of stock at $37 between now and next week and they paid a Cash Outlay of $150,000. With recent sell-offs in UAL and AAL, I thought that this was a goos risk vs reward trader, so I bought these Calls as well. Lets breakdown my trader.

The Trade: I bought the DAL 5.9.2014 37 Calls for $.74 debit
