While the release of economic data doesn't stop next week (see economic schedule highlights below), the earnings season does wind down dramatically. Most of the S&P 500 companies already have reported on the past quarter, which means dismal earnings news is largely behind us, at least for a while. About the only companies of note expected by analysts surveyed by Thomson Reuters to report falling earnings this week are Costco Wholesale Corp. (NASDAQ: COST), Wendy's/Arby's Group Inc. (NYSE: WEN), Foot Locker Inc. (NYSE: FL), Bank of Montreal (NYSE: BMO), and Steinway Musical Instruments Inc. (NYSE: LVB).

While PetSmart Inc. (NASDAQ: PETM) and Big Lots Inc. (NYSE: BIG) quarterly profits are expected to be about the same as a year ago, Liz Claiborne Inc. (NYSE: LIZ), Kenneth Cole Productions Inc. (NYSE: KCP), Ciena Corp. (NASDAQ: CIEN), and Trina Solar Ltd. (NYSE: TSL) are expected to have swung to losses in the most recent quarter.

Analyst upgrades:

• Baird upgraded Carlisle (NYSE:CSL) to Outperform from Neutral and lowered their target to $25 from $33 following the company's Q4 results citing attractive valuation and solid execution.
  
• Citigroup upgraded Talbots (NYSE:TLB) to Hold from Sell on valuation as they believe the company's cash flow is improving and does not expect the company to face bankruptcy in next three years.
  
• Jefferies upgraded shares of Spectra Energy (NYSE:SE) to Hold from Underperform on valuation following the company's Q4 results and raised their target price to $15 from $11.75.
• Costco (NASDAQ:COST) was upgraded to Buy from Neutral at UBS.
  
• AU Optronics (NYSE:AUO) and LG Display (NYSE:LPL) were upgraded to Buy from Neutral at Banc of America/Merrill.
  
• Alpha Natural (NYSE:ANR) was raised to Buy from Hold at Natixis.

MOST NOTEWORTHY: BioDelivery Sciences, Network Equipment, Barr Pharmaceuticals and Teva Pharmaceutical were today's noteworthy initiations:

• Merriman believes BioDelivery Sciences (NASDAQ:BDSI) is significantly undervalued given the positive results for BEMA Fentanyl and potential milestone payments of $60M, initiating shares with a Buy rating. They estimate fair value is in the $8-$10 range.
• Broadpoint believes Network Equipment (NYSE:NWK) is well-positioned for growth in the IP space, starting shares with a Buy rating.
• Banc of America started Barr Pharma (NYSE:BRL) with a Buy rating and $60 target, noting that the company's generic pipeline represents $30B in brand revenues and views Fosamax as the largest immediate opportunity. The firm also assumed coverage of Teva (NASDAQ:TEVA) with a Buy rating and $55 target, as they believe Teva's scale makes it the only generic company that can make a profit from aged generic products.

OTHER INITIATIONS:

• JP Morgan initiated Wintrust Financial (NASDAQ:WTFC) with a Neutral rating.
• Credit Suisse initiated Psychiatric Solutions (NASDAQ:PSYS) with an Underperform rating and $30 target.
• UBS started Weight Watchers (NYSE:WTW) with a Neutral rating and $51 target.

Most mergers are driven by the notion, sometimes wildly mistaken, that the combination will bring both a competitive advantage. Some pairs of companies, however, seem so intuitively right for one another, no bottom-line considerations should be allowed to interfere with their matrimony. Like a box of Oreos and a glass of milk, these two were meant for one another.

One aspect of American life that has been keeping up with the Dow Jones average is our waistlines. Since 1994, the percentage of adults considered overweight or obese has shot up from 55.8% to 65.9%, a bullish market (covered in barbecue sauce) indeed. In looking for partners that feed in this trough, I found two that, if merged, could make dough in both expanding and contracting economies.

The first, the obvious, is Weight Watchers International (NYSE: WTW). One of the oldest, and arguably the most successful weight loss company, Weight Watchers leverages peer- to-peer support to sell a full line of diet foods, books about weight loss and endorsed products. While its diet plan finished higher than those of other companies such as Jenny Craig in a Consumer Reports study, the fact is most customers don't succeed in maintaining their weight loss.

MOST NOTEWORTHY: Countrywide Financial (CFC), Hoku Scientific (HOKU), Lam Research (LRCX), Weight Watchers (WTW) and NutriSystem (NTRI) were today's more noteworthy downgrades:

• Friedman Billings downgraded Countrywide Financial (NYSE: CFC) to Underperform from Market Perform until credit stabilizes.

• Piper Jaffray downgraded Hoku Scientific (NASDAQ: HOKU) to Underperform from Outperform and sees several near-term risks, including competitive threats from larger and well-financed polysilicon start ups as well as financing risk.

• ThinkEquity downgraded Lam Research (NASDAQ: LRCX) to Source of Funds from Accumulate, expecting a recovery in the foundry segment but at 90nm, the nodes where Lam's market share is not high.

• Lehman downgraded Weight Watchers (NYSE: WTW) to Underweight from Equal Weight and NutriSystem (NASDAQ: NTRI) to Equal Weight from Overweight...

OTHER DOWNGRADES:

• First Albany downgraded Sketchers USA (NYSE: SKX) to Neutral from Buy.

• UBS downgraded Georgia Gulf (NYSE: GGC) to Reduce from Neutral.

• Bear Stearns cut GlaxoSmithKline (NYSE: GSK) to Underperform from Peer Perform.

• AG Edwards cut Peabody Energy (NYSE: BTU) to Hold from Buy.

Yesterday we learned that Starbucks (NASDAQ: SBUX) is taking another shot at the movie promotion business by pushing (for a cut of the action) the National Geographic movie "Arctic Tale." Starbuck's initial effort, last year's "Akeela and the Bee," had indifferent results.

While most of the big releases for 2007 already have commercial tie-ins, I thought about other companies that might make money by offering some targeted marketing. Perhaps

• Ratatouille -- KFC (Yum Brands, NYSE: YUM)
• The 40-year old Virgin -- Weight Watchers Intl (NYSE: WTW)
• Sicko -- The Church of Scientology
• Live Free or Die Hard -- Viagra (Pfizer, NYSE: PFE)
• Evan Almighty -- Chris Craft
• Transformers: The Mitt Romney Campaign
• The Simpsons Movie: Sylvan Learning
• Hairspray: Lane Bryant (Charming Shoppes, Inc., NASDAQ: CHRS)
• Hostel: Part II -- Hilton Hotels (NYSE: HLT)
• 1408 -- Hostelling International

After researching the Volumetrics plan, I'm convinced it's among the best eating strategies yet. So does Consumer Reports.

Notice that the word "diet" is not mentioned. "Diet" implies temporary while "eating strategies" and another commonly used phrase "eating plan" implies permanent changes. The book "The Volumetrics Eating Plan" by Barbara Rolls, who is a professor in the department of nutritional sciences at Pennsylvania State University, is worth a read for anyone looking to take control of their nutrition for the long term rather than just lose a few pounds for the summer.

The runner-up is the review was the Weight Watchers International Inc. (NYSE: WTW) diet plan (I'm a fan of this one) and Jenny Craig also came in a very close third.

The rest? Well, do your homework and see if there are solid tracts of science behind whatever diet plan you choose -- and don't fall for the marketing hype or baseless celebrity endorsements.

It's easy to do.

From the recent Atkins Diet craze to the newest "Best Life Diet" that counts Oprah Winfrey as an endorser, there are many plans making claims to be the best.

As Consumer Reports shows, very few are worth the bother.

Tonight on CNBC's MAD MONEY, Jim Cramer talked about diet-plays for betting-to-win off the obesity of America. On weight loss, Cramer said there are ways to profit off the diet fad after the holidays. He wants to get into the weight-loss game before the companies report Q1 results. You can burn calories or cut down calories. There are some that earn major bucks and some to avoid.

As far as a health-club play, Cramer likes Lifetime Fitness (NYSE:LTM). He disagrees with a Prudential 'Underweight' rating; here's why he liked it and why it popped after he talked about it.

He discussed NutriSystems Inc. (NASDAQ:NTRI) as one that is just as dangerous to own now as it was before it recently got hit. He said they sell direct to the consumer instead of through retail outlets. He likes Weight Watchers International (NYSE:WTW). It has a better business model because it is like a profitable A-A. Here is the full note on that one. After Cramer panned it, NTRI fell 0.7% to $43.75 and that is after it fell 15% today. Its 52-week high is $76.33 and the low is $35.01. WTW popped over 1% to $54.77 in after-hours.

• Matrix USA downgraded Texas Instruments, Inc. (NYSE:TXI) to Hold from Buy on valuation.
