MOST NOTEWORTHY: Patterson Companies, Virgin Media and MannKind were today's noteworthy downgrades:

• Patterson (NASDAQ:PDCO) was downgraded to Neutral from Outperform at Baird, as the firm's checks indicate industry fundamentals have softened and it sees greater near-term risk for dental consumables than dental equipment.
  
• Virgin Media (NASDAQ:VMED) was cut to Hold from Buy at Jefferies as they believe the company's results could be under pressure given the continued competitive activity and potential weakening of the UK economy.
  
• Piper downgraded shares of MannKind (NASDAQ:MNKD) to Neutral from Buy and lowered their target to $1.50 after Pfizer (NYSE:PFE) discontinued inhaled insulin Exubera due to an increase in lung cancer cases.

• Pantry (PTRY) was cut to Market Perform from Outperform at Friedman Billings.

Just because a company is in the health are field, it doesn't mean it's a buy. That's because investors have figured out that future demand for a product does not translate into unexpectedly high profit for the companies that meet the demand.

Obviously demand for medical products and services is going to rise as 77 million baby boomers age. But that demand does not necessarily translate into making money -- either in the product or stock markets. Why not? Because the competition is fierce. Not only are rivals going after each other with aggressive marketing but in many cases the government or pharmacy benefit managers are the buyers. And these buyers cap prices -- often at levels that make it difficult for suppliers to make a decent profit.

Furthermore, companies in this industry must invest considerable amounts in R&D to develop new products since they can't rely on profits from products that lose patent protection due to competition from generics. And the success rates of those R&D efforts seem to be dropping -- leaving many competitors with high costs, declining revenues, and uncertain futures.
