CVS Caremark (CVS), which competes with Walgreen (WAG), Rite Aid (RAD), and Wal-Mart (WMT), posted fourth-quarter data on Monday. Sales increased 7%, and adjusted earnings per share from continuing operations (excluding, in addition, a penny per share relating to a tax benefit) came in at 78 cents -- good for a growth rate of over 11%. That bottom-line performance matched analyst projections, according to our earnings preview.

As we all know, matching expectations is sometimes the death of a stock. The market has no conscience when it comes to mercilessly punishing an equity for not going beyond the call of the analysts. However, CVS actually did pretty well yesterday, rising 5% by the end of the session; the move was backed by healthy volume.

Walgreens (WAG), the drug superstore chain that has found renewed competition with mass retailers Walmart (WMT) and Target (TGT), will enter the fresh food and prepared meal market in some of its stores. The reason: Walgreens wants to cater to "time starved" shoppers. This must be the type of shopper who doesn't want to slog through acres of a big-box store only to stand in a checkout line for 10 minutes, right?

Walgreen (WAG) shares are undervalued," says J. Royden Ward, who assesses stocks based on a strict value-basis. His the latest from The Cabot Benjamin Graham Value Letter.

"Walgreen, founded in 1901, is the largest drug store retailer based on sales. In addition to 7,000 drug stores, the company operates 680 health clinics within existing stores and on employer worksites.

Walgreen's (WAG - option chain) stock is trading lower today after the company said its same-store sales fell 0.3 percent last month, the first monthly sales decline since February. According to the company, this dip in sales is due to WAG stocking fewer seasonal items, which is better than the alternative of shoppers just not buying anything. If you think this stock won't be rising too far in the coming months, then it could be a good time to look at a bearish hedged play on WAG.

This morning, WAG opened at $36.16. So far today the stock has hit a high of $37.29 and a low of $35.92. As of 12:00, WAG is trading at $36.84, down 16 cents(-0.5%). The chart for WAG looks neutral and S&P gives WAG a neutral 3 STARS (out of 5) hold ranking.

I'm reiterating my buy ratings the nation's two premier drug store chains: CVS Caremark (CVS), first recommended on February 16, 2009, at a price of $27.30; and Walgreen (WAG), first recommended on February 17, 2009, at a price of $25.46. If you bought CVS in February, you're up 25%; WAG, up about 40%.

As expected, each has performed well on increased store traffic stemming from the H1N1 flu virus (trips to purchase hand sanitizers, other disinfecting items, and flu symptom comforts), which has offset reduced traffic for other drug store trips, due to the U.S. recession.

Here are a few highlights from this past week's earnings coverage on BloggingStocks:

• Cintas Corp. (CTAS) received an analyst's downgrade following its Q2 earnings report.
• ConAgra Foods Inc. (CAG) shares spiked after it posted better-than-expected Q2 earnings.
• Finish Line Inc. (FINL) posted surprise Q3 earnings, ending a streak of quarterly losses.
• Giga Media Ltd. (GIGM) was downgraded due to its disappointing Q2 report and lack of visibility.

Walgreen (WAG), a drugstore chain that competes with CVS Caremark (CVS) and Rite Aid (RAD), issued fiscal Q1 numbers on Monday. The growth rates were impressive.

Total sales were up 9.5%. Net income increased almost 20% to 49 cents per diluted share. Operational cash flow was higher by over three times. According to our earnings preview, analysts were expecting 48 cents per share. Of course, since there were restructuring charges included in the above per-share profit stat (equal to 3 cents per share), the beat is better than it looks. This was indeed a good quarter.

Career Education (CECO) closed at $22.30, selling off 19% in late afternoon trading on Dec. 18 after the Office of Inspector General sent out a negative letter concerning the for-profit education group. CECO January option implied volatility is at 58, above a level of 45 from December 16. April volatility is at 55; above its 26-week average of 43 according to Track Data, suggesting traders purchasing options to hedge price movement.

Three stocks with IV rise on Dec. 18: Sun Microsystems (JAVA) +3%, PowerShares DB US Dollar Index Bullish Fund (UUP) +2%, Walgreen's (NYSE-WAG) +2%, according to IVolatility.

Even in a holiday shortened week so close to the end of the calendar year, there are still some earnings reports dribbling in. Question is, will any of the companies reporting quarterly results this week offer up a gift for investors?

Apropos of the season, analysts surveyed by Thomson Reuters have high expectations for American Greetings Corp.'s (AM) fiscal third quarter 2010 earnings. The nation's second largest provider of greeting cards announced record second quarter results and declared a quarterly dividend during the three months that ended in November. American Greetings is expected to report that earnings rose 43.9% from a year ago to $0.66 per share. Revenue for the quarter is expected to total $445.4 million, or 1.9% lower than a year ago. So far, the full-year forecast is for its profit to more than double to $2.00 per share while revenue falls 5.6% from a year ago to $1.6 billion. This Cleveland-based company creamed earnings estimates in the past two quarters.

Rite Aid (RAD), whose colleagues include CVS Caremark (CVS) and Walgreen (WAG), reported third-quarter results on Thursday. Although they did show improvement, I think most investors would be better off staying away from the stock.

According to this summary at Reuters, top-line sales decreased a little under 2%, and the loss per share came in at 10 cents. This was a lot better than the 30 cents per share lost in the comparable quarter. Expectations were for the red ink to be closer to 18 cents per share.

If consumers try a little harder this year, the holiday season has a shot of hiding memories of last year's nightmare for retailers. The retailers are doing their part, with Walmart (WMT), Gap (GPS), RadioShack (RSH), Walgreens (WAG) and many others opening their doors Thanksgiving Day, giving shoppers the opportunity to start their spending early. There's a chance that consumers will spend a bit more this year to thank each other for keeping their belts so tight for so long.

Forecasts of the season's ultimate result remain difficult to pin down. Some expect a year-over-year decline of 3%, and predictions range to an increase of 2%. Credit is harder to come by, and unemployment remains over 10% and at a 26-year high. But, the pressures on spending are offset by pent-up emotion and a stabilizing financial environment -- even if it isn't getting better yet, it doesn't seem to be getting worse.

If Thanksgiving is a bird, a beer and a football game for you, prepare to have your thinking challenged. Many retailers are looking to get a head start on Black Friday this year, opening a day early, some of them for the first time. Most Old Navy Stores (GPS) will open their doors on Thursday, along with Wal-Mart (WMT), Toys "R" Us, RadioShack (RSH) and Walgreen's (WAG). Rather than bet solely on Friday, retailers are looking to eke every last dime they can out of the holiday season this year.

The National Retail Federation expects holiday spending to drop 1% this year to $437.6 billion. "Retailers need to be competitive," says NRF spokeswoman Ellen Davis. "There's a lot riding on the success of November and December retail sales."
