Today was a busy economic day with data, but the selling in Asia as a "sell the news" reaction from the first Japan rate cut in seven years should have ruled the roost. Employment costs came in at 0.7% as expected, and personal income and spending showed no surprises. The markets also ignored a weak Chicago purchasing managers reading. This was a horrible month, but the DJIA ended up roughly 1,000 points higher from the close last Friday.

Below are today's unofficial closing bell levels:

Dow 9,325.01 +144.32 (1.57%)
S&P 500 968.75 +14.66 (1.54%)
Nasdaq 1,720.95 +22.43 (1.32%)

DivX, Inc. (Nasdaq: DIVX), which develops video applications, thought it could succeed in the topsy-turvey web business. So, in late 2006, the company launched Stage6.com.

Well, for the most part, it's not as easy as it looks and now DivX is closing down the site. Interestingly enough, DivX wasn't able to find a buyer for the property.

What happened? Well, I had a chance to interview Chase Norlin, who operates Pixsy (an online search engine). According to him:

"Stage6 likely needed a sugar-daddy to support operations going forward (e.g. acquirer with resources or large capital raise). Given the popularity of the service and the high quality of their streams, they probably had a significant bandwidth bill without the monetization to support that in the short term. Additionally, legal issues around copyrighted material may have added to the decision."

Shares in video software company DIVX Inc. (NASDAQ: DIVX) are up about 17% before the open on strong earnings. Stock in Chinese company Xinhua Finance Media Ltd. (NASDAQ: XFML) is 12% higher on news that it will gain SOX compliance with the SEC.

Momenta Pharma (NASDAQ: MNTA) is off over 50% on news that the FDA rejected its generic blood thinner. And shares of content delivery company Limelight Networks (NASDAQ: LLNW) are down 9% on weak guidance for the fourth quarter.

Looks like Yahoo, Inc. (NASDAQ: YHOO) has put yet another feather in its cap, as the internet company will have its web browser toolbar distributed along with video player software from company DivX Inc. as of this week. DivX makes a very popular video compression codec technology that is used in millions of downloadable videos.

Yahoo!'s toolbar is how millions of Yahoo! users interface with the company's various offerings every day, since it is always visible and available on a customer's web browser. DivX had worked previously with Google, Inc. (NASDAQ: GOOG) for about two years, and the relationship was apparently still in good standing despite the change to Yahoo!. According to a DivX representative, "We had worked with Google for two years and it was a good relationship. The deal we had with Yahoo was the most attractive to us at this time."

In other words, Yahoo! probably offered more to DivX to be included as a co-brander of every download of DivX video player and authoring software, which is not surprising considering the large moves the Sunnyvale, California has made in the last month to start playing more firmly with internet search leader Google.

Boasting a market cap of $19 billion, WPP Group (ADS) (NASDAQ: WPPGY) focuses on the communications needs of major clients and produces multi-million dollar ad campaigns. To protect its franchise, the company is moving into social networking and video. Its most recent deal is a strategic investment in VideoEgg.

VideoEgg is a privately-held company that provides editing tools and an ad network that serves 15 million videos a day. The company has distribution deals with more than 60 online communities, including Time-Warner's (NYSE: TWX) AOL, Tagged, and Bebo.

According to a recent Jupiter Research report, about a quarter of adult Internet users in the US regularly visit social networking sites. Users create profiles, meet new friends, and share videos.

This represents a big opportunity for brand advertisers. "Social networking sites are extremely interesting to brands because the audiences are filled with users seeking membership in particular interests," said Robb Hecht to me in an interview. Hecht operates media consulting firm IMC Strategy Lab.

MOST NOTEWORTHY: The interactive entertainment sector, CVS Corp (CVS) and two large retailers, J.C. Penney (JCP) & Federated Department Stores (FD), topped today's notable initiation list:

• AG Edwards initiated Electronic Arts Inc (NASDAQ: ERTS), Activision, Inc (NASDAQ: ATVI), THQ Inc (NASDAQ: THQI) with Buy ratings and Take-Two Interactive Software (NASDAQ: TTWO), Midway Games Inc (NYSE: MWY) and GameStop Corp (NYSE: GME) with Hold ratings. The firm believes the video game industry is well-positioned for above-average L-T growth based on positive demographic trends. In addition, AG Edwards expects overall U.S. video game industry retail dollar sales to grow by 39% in 2007.

• Elsewhere, Wachovia initiated CVS Corp (NYSE: CVS) with an Outperform rating. The firm believes CVS is well-positioned to take advantage of the fundamentals in the PBM business and find cost synergies from the merger.

• Thomas Weisel initiated both J.C. Penney (NYSE: JCP) and Federated Department Stores (NYSE: FD) with market Weight ratings. The firm believes JCP will have more modest margin expansion going forward and believes high expectations and valuation for FD will limit its outperformance in the near-term.

MOST NOTEWORTHY: Norfolk Southern and Abercrombie & Fitch were today's most notable upgrades.

• Citigroup upgraded shares of Norfolk Southern (NYSE: NSC) on valuation as they believe the recent weakness has brought shares to an attractive level.

• Merrill Lynch upgraded shares of Abercrombie & Fitch Co 'A' (NYSE: ANF), as the firm does not believe the stock's current valuation reflects the company's growth opportunities; additionally, the firm sees significant growth opportunities at the Hollister brand and expects free cash flow growth in 2007.

OTHER UPGRADES:

• Goldman Sachs upgraded Wellpoint Inc (NYSE: WLP) to Buy from Neutral, believing the company is better positioned in comparison to their peers to weather increasing price competition.

• UBS upgraded Ingersoll-Rand (NYSE: IR) to Buy from Neutral.

Cramer reviewed another "do you know what you own" on MAD MONEY last night. A hot stock that has been on fire is DivX Inc. (NASDAQ:DIVX). He was positive on it on at $18+ and now it is up about 50% from there. What does the company do and is it worth owning?

DivX makes video compression software that it licenses to DVD player companies that stream and download. Cramer noted the Google Inc. (NASDAQ:GOOG) relationship, as well as the company having great opportunities in Eastern Europe and in India because other video formats are too expensive to license.

As far as whether you should sell or hang on from here, Cramer said there are 4 buys and 1 hold from the Street. This stock is a lower-tier that might not get covered everywhere, and the IPO-lock-up doesn't come until March. Cramer thinks that may keep a lid on it until then and it could sell shares.

It is hard to gauge the real size of its market because it is a niche within a huge market and it competes with RealNetworks Inc. (NASDAQ:RNWK) and Microsoft Corp. (NASDAQ:MSFT). It trades at 17-times sales, so everything that was known back then is still known now, and he wouldn't keep hanging around in the stock. Cramer says to take profits here, and he would like it a lot cheaper than it is now.

DIVX closed up 2% at $27.69, and while it ticked up after Cramer was saying good things, it was down in after-hours after he said to avoid it.
