MGM – MGM Resorts International – The operator of casino resorts attracted bullish options players this afternoon with the price of the underlying stock rallying as much as 3.65% to an intraday high of $11.36. It looks like investors expecting shares to continue higher ahead of August expiration purchased call options. The most optimistic of individuals picked up approximately 5,200 calls at the August $13 strike for an average premium of $0.21 each. Call buyers at this strike make money if MGM’s shares surge 16.3% to trade above the average breakeven price on the upside at $13.21 by expiration day next month. Other bullish traders who are perhaps hoping shares can retain the present rally, but not looking for shares to move much higher ahead of expiration in August, sold 3,000 puts at the August $10 strike for an average premium of $0.37 each. If investors are selling these puts outright, they walk away with the full premium received on the transaction as long as MGM’s shares exceed $10.00 through expiration day. Investors populating MGM Resorts International today exchanged more than 2.2 call options for each single put option in play on the stock as of 3:45 pm ET. MGM is scheduled to report its second-quarter results ahead of the opening bell of August 3, 2010.
