Today’s tickers: CVS, DRIV, AVP, WAG, ADBE, PHM & COP 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.

The strangle-strategist appears to have sold 2,500 calls at the November $35 strike for a premium of $1.35 each, and sold the same number of puts at the lower November $28 strike at a premium of $0.525 apiece. Gross premium pocketed on the transaction amounts to $1.875 per contract. The trader keeps the full amount of premium received on the strangle play if DRIV’s shares trade within the boundaries of the strike prices described through expiration day. The short positions in both call and put options expose the investor to potentially devastating losses in the event that shares rally above the upper breakeven price of $36.875, or should shares slip beneath the lower breakeven point at $26.125, by November expiration. Digital River is scheduled to report third-quarter earnings after the closing bell on November 3, 2010. An earnings miss or surprise could adversely impact the strangle player if the price of the underlying…
