Oppenheimer believes this represents a $300M shift from KLA-Tencor's dominant market share in reticle inspection.

MOST NOTEWORTHY: The Managed Care sector, Keryx Biopharma and Citrix Systems were today's noteworthy downgrades:

• Goldman downgraded the Managed Care sector to Neutral from Attractive following WellPoint's (NYSE: WLP) reduced 2008 outlook. The firm said WellPoint's issues reflect a company specific underwriting error but also industry-wide pricing pressures which increase the risk of a cyclical slowdown in managed care. WellPoint was also downgraded to Neutral from Overweight at JP Morgan.
  
• Banc of America cut Keryx Biopharma (NASDAQ: KERX) to Neutral from Buy and lowered their target to $1.00 after Sulonex failed to meet its primary endpoint.

Last week, Citadel Investment Group, a Chicago hedge fund, bought E*Trade Financial (NASDAQ: ETFC)'s collateralized debt obligation (CDO) portfolio for 27 cents on the dollar according to The Wall Street Journal [subscription required]. If this price was applied to the Level 3 assets of nine of the largest banks, it would wipe out the capital of three of them.

It's important to point out, before presenting this analysis, that the 27 cents on the dollar price that Citadel paid applied only to E-Trade's CDOs. It may represent a worst case scenario price for these banks. Furthermore, the Level 3 assets of these nine banks include other illiquid securities besides their CDOs. Finally, the calculations I'll show are based on the most recent Level 3 assets and equity of these banks as of last month.

Having said that, here are the three banks whose capital would be wiped out if that 27 cents on the dollar valuation was applied to their Level 3 assets and written off from their most recent capital levels:

MOST NOTEWORTHY: Trident Microsystems, Comcast, Level 3 Communications, Ambac Financial and MBIA Inc were today's noteworthy downgrades:

• Jefferies downgraded shares of Trident Microsystems Inc (NASDAQ: TRID) to Hold from Buy and lowered their target to $9 from $20 following the company's mixed quarter as they expect TRID to lose share in the TV market and face increasing price pressure. Shares were also downgraded to Hold from Buy at Deutsche Bank. Oppenheimer lowered Trident to Neutral from Buy, citing disappointing December guidance, delay in TV ramp, and expectations that 2008 will be a peak year for TV chip ramp revenues.
• CIBC downgraded shares of Comcast Corporation (NASDAQ: CMCSA) to Sector Performer from Outperformer following the weak Q3 results to reflect increasing competition in telco video, slower broadband growth and the weakening economy.
• JP Morgan downgraded Level 3 Communications Inc (NASDAQ: LVLT) to Neutral from Outperform following disappointing Q3 results and guidance.
• Friedman Billings downgraded shares of Ambac Financial Group Inc (NYSE: ABK) and MBIA Inc (NYSE: MBI) to Market Perform from Outperform citing lack of near-term catalysts and uncertainty surrounding the credit markets.

• WestLB downgraded GlaxoSmithKline PLC (NYSE: GSK) to Sell from Add.
• Societe Generale downgraded France Telecom (NYSE: FTE) to Hold from Buy.

Level 3 Communications Inc (NASDAQ: LVLT) flexed it muscles yesterday when it announced that it would be dropping prices for its content delivery network (CDN) services. Level 3's stock jumped over 4% on the news.

The IP-centric service provider has boasted for years about its low-cost structure and constant inferences that it could slash prices and drive volume unlike any other network provider in the country, if not the world. This is the first time the company has been so public about a specific price action.

Lisa Guillaume, VP of CDN Product Development for Level 3, said CDN services usually carry a 20 to 30% premium over the cost of transport, in a LightReading.com interview. This pricing action eliminates that differential. The ownership of a massive long-haul network and CDN platform will allow Level 3 to do this profitably, she added.
Level 3's network was designed to play the price-elasticity curve for bandwidth consumption in the Internet age. Volume increases in bandwidth consumption would offset per-unit price declines for transporting all those bits of information for MySpace, YouTube and Wallstrip.com.

Level 3 reported light revenue and earnings in the most recent quarter as it attempts to integrate seven acquisitions that it has completed during the last eighteen months. Demand for its services is strong, but the company is having issues getting the new customers onto their network.

After years of anticipation, possibly yesterday's announcement is a sign that Level 3 is finally ready for prime time and will be able to drive its business model, leading to higher revenue and profit growth. The company is due to report earnings on October 23 -- a must listen to call for investors.

MOST NOTEWORTHY: News Corp, Limelight Networks, Corning and Carmike Cinemas were today's noteworthy initiations:

• RBC Capital is positive on News Corporation's (NYSE: NWS) strategy of investing cash flow away from mature enterprises to fund high-growth initiatives such as Sky Italia and Fox Interactive Media. The firm initiated shares with an Outperform rating and $26 target.
  
• Kaufman Brothers rates Limelight Networks Inc (NASDAQ: LLNW) a Sell based on a significant increase in the competitive environment with Akamai discounting on large deals, Level 3 Communications Inc (NASDAQ: LVLT) introducing a competitive offering in November 2007, Korean major-CD Networks becoming aggressive, and new entrants becoming aggressive with their value propositions.
  
• Deutsche Bank initiated Corning Inc (NYSE: GLW) with a Buy rating and $31 target as they believe shares are fundamentally undervalued given the company's strong fundamentals and promising outlook.
  
• Carmike Cinemas Inc (NASDAQ: CKEC) was started at JP Morgan with an Overweight rating. The firm said the company is the most exposed to 3-D, which could lead to potential upside due to low margins and leverage capital structure.

OTHER INITIATIONS:

• UBS started shares of St. Jude Medical Inc (NYSE: STJ) with a Sell rating and $43 target and shares of Medtronic Inc (NYSE: MDT) with a Buy rating and $64 target.
  
• Bear Stearns initiated shares of TJX Companies Inc (NYSE: TJX) and Ross Stores Inc (NASDAQ: ROST) with Peer Perform ratings.

• Applix Inc (NASDAQ: APLX) was downgraded to Neutral from Buy at First Albany and SunTrust Robinson Humphrey following the acquisition by Cognos Inc (NASDAQ: COGN).
• Time Warner Inc (NYSE: TWX) was downgrade to Neutral from Buy at Pali Capital. The firm has lost faith in Time Warner's executive management team and Board of Directors and feels the outlook for AOL is concerning.
• Gabelli downgraded Apple Inc (NASDAQ: AAPL) shares to Hold from Buy on iPhone concerns and valuation as they view the iPhone price cut as an indication that sales are not living up to management's expectations.
• Buckingham Research downgraded shares of Level 3 Communications Inc (NASDAQ: LVLT) to Underperform from Neutral citing deterioration in demand for some key products.

OTHER DOWNGRADES:

• SL Green Realty (NYSE: SLG) was downgraded to Equal Weight from Overweight at Lehman Brothers.

Global Crossing Limited (NASDAQ: GLBC), Time Warner Telecom (NASDAQ: TWTC) and Level 3 Communications Inc (NASDAQ: LVLT), had one heck of a rally the past few day, despite horrific market conditions.

Both Global Crossing and Time Warner Telecom reported very strong results. Global Crossing's stock is selling from $22, up from $17.50 earlier this week. Why? The international telecommunications service provider reported a 500 basis-point improvement in its gross margin. This is a company that had some of the lowest gross margins in the telecommunication sector a few years ago. EBITDA came in $4 million ahead of analysts expectations. A good sign for a company that has often missed financial targets.

Jefferies has EBITDA going from $144 million in 2007 to $388 million by 2010. The combination of better industry conditions and recent acquisitions bodes well for the once-bankrupt telecom provider.

Time Warner Telecom also reported strong results earlier this week and should be looked at.

Emerging telecommunications providers got hit pretty hard after Level 3's results came in lite. Level 3 said demand for its services was strong, but messed up getting new customers on the network. Investors were not sure to believe management. From the results of both Global Crossing and Time Warner Telecom, it appears the demand for service from these new service providers is most definitely strong.

Big Band Networks (NASDAQ: BBND) had a bad quarter. The provider of infrastructure for moving video around the internet lost 25% of its value today down to $10.60. It announced a modest $54.5 million in revenue and earnings $.07 a share. An IPO this year, Big Band is now off from a high of $21.63.

LimeLight (NASDAQ: LLNW), a content delivery network that competes with industry leader Akamai (NASDAQ: AKAM), is off from $24.33 just after its IPO to $16.15. Akamai's stock is down 35% this year. It earnings disappointed investors.

In a related part of the internet infrastructure, Level 3 (NASDAQ: LVLT) came up with flat revenue and lackluster earnings for the last quarter. Its shares went from $6.42 to $4.93 after its announcement. It has recovered a bit since then.

But, there is a trend here. The companies that provide the pipes and pipe parts to get video around the internet should be doing very well during the "YouTube" generation. They are not.

Two things may be happening. The first is the the service providers are in such fierce competition for business in a market that Wall Street views as hot that margins are being compressd by price cuts. The other possibility is that, after two years of extremely rapid expansion, video streaming and consumption is flattening.

An industry that everyone thought would be a big winner turns out to be the opposite.

MOST NOTEWORTHY: SanDisk (SNDK), Indevus Pharmaceuticals (IDEV), Integra LifeSciences (IART) and Level 3 Communications (LVLT) were today's noteworthy initiations:

• Morgan Stanley initiated shares of Integra LifeSciences (NASDAQ: IART) with an Equal Weight rating and $55 target, citing competitive risks from larger competitors.

• Shares of Level 3 Communications (NASDAQ: LVLT) were initiated at Raymond James with an Underperform rating, as the firm believes estimates will be difficult to achieve given high debt levels and free cash flow.

With weak futures this morning and panic selling at the end of the trading day yesterday, it is time to start looking at buying some stock. The market is so oversold it could mean we are due for a pretty good short term rally. Stocks to consider include:

• Home Depot Inc. (NYSE: HD) -- Barron's was on target this past weekend writing that the home-improvement retailer could have considerable upside in the years ahead. The company still has a tender on the market between $39 and $44, the record day of which may have passed, but there is $10 to $12 billion in buybacks still to come.
• National Semiconductor Corporation (NYSE: NSM) -- iPhones are selling and the move to wireless is still the rage, which fits into this wireless semiconductors sweet spot. Following a strong earnings report and a huge share repurchase agreement, the stock rallied to $29.60, but it is now down below $26, essentially erasing all the gains for the good earnings. This is a good entry point.
• AES Corporation (NYSE: AES) -- The Fly blogged about this one the other day, with the stock down 15% from its recent high, and continuing to trade poorly, this stock may be worth scooping up.

We blogged about a trading opportunity in Level 3 Communications Inc (NASDAQ: LVLT) the other day, and the stock rallied from $5.00 to $5.40. For those who were nimble enough to sell into yesterday's strength, that trade worked out well. The trades listed above should also work out well as this oversold market has a short-term rebound.

Level 3 Communications (NASDAQ: LVLT), the IP telecommunications company, got hit pretty good yesterday due to the market's broad-based sell-off and its coming up short on revenue.

Management cited integration issues due to its seven recently completed acquisitions as the prime reason. The sales backlog is increasing but it is slow bringing customers on to its network. Level 3 will be a show-me stock for the next few quarters as management will have to hit their numbers to regain investors' confidence. October is expected to be another weak quarter, but business is expected to ramp in 4Q.

However, with what looks like a weak or a flat opening this morning in combination with yesterday's sell off, a quick recoil is possible from its oversold condition for traders to make a nice profit on.
