Valentine's Day may be a commercialized holiday to some, but there's no denying that its big business. And this coming Valentine's Day may be extra sweet since it falls on a Sunday, making it a great excuse for a romantic night out. In fact, total Valentine's Day spending is expected to reach $17.6 billion this year, up 3.3% over 2009, according to consumer spending researchers at IBISWorld.

That's a big payday, and one that investors should be paying attention to.

Eating less is being rewarded in a strange new way. Thinner employees at Whole Foods (WFMI) will enjoy deeper discounts on food, leading to an even wider disparity relative to the ... ummmm ... "bigger-boned" employees. A new employee rewards program called "Health Starts Here" offers employees discounts based on body mass index. Hit the gym, go for a jog or simply enjoy the perks of a naturally buzzing metabolism, and you can save a fortune. Carry around a little extra heft, and you'll pay more to maintain it.

At present, every Whole Foods employee receives a 20% discount on purchases in the store. By sweating to the oldies, however, they can take that discount to 30%. But dieting like a model won't work: nicotine use is a disqualifier. So, if you're trying to smoke your way to svelte, find another way.

With close to 60 million users, Twitter is a force corporate marketing departments just can't ignore. The reach offered by this microblogging platform is profound, and skipping it means yielding digital turf to the competition.

Yet, as the country's major brands have flocked to Twitter, not all have mastered it. Some merely push headlines and deals, while others have used it as a way to open a dialogue with their customers, build relationships and ultimately grow their businesses. A study by The Big Money sought to determine the dozen companies that are mastering Twitter and why they are the masters.

All three of the major indexes finished Tuesday in the red, but there were several big names that moved up to new 52-week highs in Tuesday's trading.

Walgreen Co. (NYSE: WAG): The drugstore giant had a really good day on Wall Street after posting better than expected earnings in the morning before the market opened. The company posted earnings of 44 cents per share versus analyst estimates of 39 cents. The stock set a new 52-week high of $38.44 and closed the day up 9.2% at $37.35.

Here are some highlights from last week's earnings coverage from BloggingStocks:

• Activision Blizzard Inc. (NASDAQ: ATVI) reported better-than-expected Q2 results, sending shares higher.
• Blackstone Group (NYSE: BX) said it swung to a Q2 profit despite a dearth of leveraged buyouts.
• CBS Corp. (NYSE: CBS) Q2 earnings declined but still topped estimates, sending shares higher.
• Coinstar Inc. (NASDAQ: CSTR) reported stellar Q2 results driven by its the popularity of RedBox.
• Clorox Co. (NYSE: CLX) posted solid Q4 earnings but said revenues were flat due to currency effects.
• Duke Energy Corp. (NYSE: DUK) lower Q2 earnings beat expectations by a penny but revenue fell short.

Whole Foods Markets, Inc. (NASDAQ: WFMI), once the grocery darling of the investing market, took a serious wrong turn somewhere in the M&A market in 2007. Ever since the ill-fated acquisition of Wild Oats, WFMI has taken a dive, plunging from highs in the $60s (2006) and $50s (until late 2007) to as low as $8.68 this past December. So it was with great joy that investors heralded news of the company's fiscal third quarter results last night, exceeding analyst expectations, with earnings per share of $0.25, or $35.0 million, and sales up 2% over the year-ago quarter, to $1.9 billion. Same-store sales declined compared to the year-earlier quarter, but reversed their declining trend, down 2.5% from Q3 2008 but up from Q2 2009.

The markets closed down in negative territory, but today will feel like a win to many traders. Each day the news keeps getting a set up for a sell-off and nothing materializes. Bears are even getting frustrated because of no substantial pullbacks. The weaker employment data had little dent, but then the weaker services market kept the rally from emerging today.

Here are today's unofficial closing bell levels:

Dow 9,280.97 -39.22 (-0.42%)
S&P 500 1,002.68 -2.97 (-0.30%)
Nasdaq 1,993.05 -18.26 (-0.91%)

It was easy to discount a company dedicated to selling high-end groceries in the midst of a terrible global downturn. And Whole Foods (NASDAQ: WFMI) has indeed suffered from investor fears. Shares of the company fell from year-ago levels of about $22 per share to lows of near $8 per share in the dark days of December 2008. They have since rebounded to the $22 level on green shoots speculation. On Monday, however, they tumbled again to $18.80. Is it time to buy?

That's a tricky question. First, the positives. Whole Foods is a well-managed grocery chain. It has been extremely disciplined in its expansion push, choosing good locations. It has also overcome relatively low revenues per employee by posting higher margins on items and much higher average cash register rings.

We all know the impact that celebrities have on businesses. One of the most obvious instances of this phenomenon comes from the Oprah Winfrey Show. For example, when a title makes it into her book club, millions of loyal followers immediately take action, and sales follow.

These days, Michelle Obama is giving Oprah a run for her money. The First Lady is being closely watched by millions, and she too has a loyal following. She also appears to have a fashion sense that resonates with consumers around the globe. We all saw the number of stories and speculation about her gown during the inauguration.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

• Abercrombie & Fitch Co. (NYSE: ANF) reported dismal Q1 numbers as same-store sales plunged.
• Applied Materials Inc. (NASDAQ: AMAT) dismal Q2 results were in line with analysts' expectations.
• Bankrate Inc. (NASDAQ: RATE) reported lower earnings and revenue for Q1 and offered no guidance.
• Blockbuster Inc. (NYSE: BBI) earnings, revenue, and same-store sales all fell in the first quarter.
• Dr Pepper Snapple Group (NYSE: DPS) Q1 earnings declined but still topped analysts' expectations.

Whole Foods Market, Inc. (NASDAQ: WFMI) reported its earnings at $0.19 non-GAAP EPS and $1.86 billion in revenues for the second quarter, and Thomson Reuters had consensus estimates of $0.18 EPS and $1.87 billion. The earnings included non-cash asset impairment charges of approximately $13 million, or $0.05 per share.

There are several things that are good about the quarter and there are a few issues. Same store sales were -4.1%, yet it showed operating cash flow of $173 million and generated $98 million of free cash flow. The company also maintained certain aspects of guidance, at least sort of. It sees opening two additional stores (including one relocation) in the third quarter and sees opening three stores in the fourth quarter, and is still waiting on the divestment approval from the FTC.

As earnings season begins to wind down, some apparel retailers are scheduled to report quarterly results this week. Analysts polled by Thomson Reuters anticipate that Walmart Stores Inc. (NYSE: WMT), the 800-pound gorilla in the space, will report that it earned $0.77 per share in the first quarter, about the same as in the first quarter of last year. But JCPenney Co. (NYSE: JCP), Kohl's Corp. (NYSE: KSS), Nordstrom Inc. (NYSE: JWN), and Urban Outfitters Inc. (NASDAQ: URBN) are expected to report lower profits for the first quarter as consumers continued to hold off on spending. Macy's Inc. (NYSE: M) and Abercrombie & Fitch Co. (NYSE: ANF) are expected to have swung to a loss year over year.

Whole Foods Market Inc. (NASDAQ: WFMI) and Winn Dixie Stores Inc. (NASDAQ: WINN) are likewise expected to report declining earnings, while the Great Atlantic & Pacific Tea Co. (NYSE: GAP), parent of the A&P supermarket chain, is expected to have narrowed its net loss 68.9% to $0.28 per share.

Here are some highlights from this past week's earnings coverage from BloggingStocks:

• Agilent Technologies Inc. (NYSE: A) Q1 earnings were cut almost in half and were lower than expected.
• AT&T Inc. (NYSE: T) earnings expectations for 2010 resulted in an analyst's upgrade.
• BioMarin Pharmaceutical Inc. (NASDAQ: BMRN) was downgraded following its Q4 earnings report.
• CBS Corp. (NYSE: CBS) beat Q4 earnings expectations but slashed its quarterly dividend.
• Crocs Inc. (NASDAQ: CROX) posted a smaller-than-expected Q4 loss but sales and gross margins fell.
• Deere & Co. (NYSE: DE) Q1 earnings and revenue fell and it offered guidance below estimates.
• Deutsche Telekom (NYSE: DT) was upgraded on confidence ahead of the company's earnings report.
• Hewlett-Packard Corp. (NYSE: HPQ) reported a bigger-than-expected drop in Q1 earnings.

Today's markets were under pressure most of the day after weekly jobless claims remained higher than estimates and after wholesale inflation rose more than expected. Earnings disappointments also added some pressure, yet oil rose sharply today with futures up over 10% at $38.60 late in the day after oil inventory levels were reported. Here are today's unofficial closing bell levels:

Dow 7,465.79 -89.84 (-1.19%)
S&P 500 778.93 -9.49 (-1.20%)
Nasdaq 1,442.82 -25.15 (-1.71%)
