CVS – CVS Caremark Corp. – The better-than-expected fourth-quarter earnings report from Walgreen Co. this morning helped CVS’s shares higher during the trading session. Shares rallied as much as 3.365% to rein in an intraday high of $31.64. The increase in the price of the underlying stock inspired one options player to extend bullish sentiment on the stock by initiating a calendar roll. It looks like the investor purchased 10,000 calls at the November $30 strike at a premium of $1.11 each back on September 17, 2010, when shares were trading around $29.72 each. The surge in shares since the purchase bumped up premium on those now in-the-money calls, which the investor sold today for a premium of $2.09 apiece. Net profits on the sale amount to $0.98 per contract. Next the investor renewed optimism on CVS by purchasing a fresh batch of 10,000 calls at the higher January 2011 $32 strike at a premium of $1.64 a-pop. Profits on the new position are available to the trader if CVS’s shares jump 6.3% to surpass the effective breakeven price of $33.64 by expiration day in January.
