Analyst initiations:

MOST NOTEWORTHY: The Metals and Mining sector, Lamar Advertising and Rigel Pharmaceuticals were today's noteworthy initiations:

• Banc of America initiated the Metals and Mining sector with an Equal Weight rating and believes investors should take a selective approach to stocks in the group. The firm initiated Alcoa (NYSE: AA) and RTI International Metals (NYSE: RTI) with Buy ratings and a $44 target and $41 target, and started Allegheny Tech (NYSE: ATI), Century Aluminum (NASDAQ: CENX) and Titanium Metals (NYSE: TIE) with Neutral ratings and a $64 target, $58 target and $12 target, respectively.
  
• Lamar Advertising (NASDAQ: LAMR) was initiated at Caris with an Above Average rating and $40 target. Caris is positive on the company's North American focus and exposure to the aggressive deployment of digital boards.
  
• Stanford believes Rigel Pharma's (NASDAQ: RIGL) lead drug R788 has the potential to be the first oral drug for rheumatoid arthritis and expects clinical news flow and partnerships to serve as catalysts. Shares were initiated with a Buy rating and $30 target.

OTHER INITIATIONS:

• Thomas Weisel assumed Salesforce.com (NYSE: CRM) with an Overweight rating and $90 target.

• JP Morgan started Ares Capital (NASDAQ: ARCC) with an Underweight rating.

Armored vehicle maker Force Protection (NASDAQ: FRPT) has been slammed down to the single digits on fears that its sole product might be on the way out because of cuts in government spending. Who knows? The CEO says the company is doing fine, but the downtrending stock price is much more convincing. If the stock price is meant to make up lost ground, it should have no problem breaking out past $6, which it has not been able to do for the past few months. I'd avoid until the stock shows some strength.

Within the past few days, IDM Pharmacueticals (NASDAQ: IDMI) has had a huge run-up from under $1 to nearly $4 and a substantial drop to just under $2 -- all due to some positive drug news that was already known since November 2007, and of course the CEO's optimism about European approval. Do I believe the CEO? Yeah right! My distrust of CEOs is dwarfed only by my distrust of biotech CEOs! This company is not in the same league as other recently hot biotechs like Savient Pharmaceuticals (NASDAQ: SVNT) and Rigel Pharmaceuticals (NASDAQ: RIGL). Avoid, with a short bias on any spikes.

When I wrote this article about A-Power Generation Systems (NASDAQ: APWR), all the variables were aligned for a great run-up. I wanted to hold, but the volume and share price didn't live up to my expectations, so I sold quickly. Now, this company, potentially the new First Solar (NASDAQ: FSLR) of wind energy, has nearly retraced to its original breakout area around $15, so the risk has gone down ... but so has the reward. If you're a long-term investor, this is a solid choice, but I need it to break its previous highs at $19 to make me a buyer again. Avoid, with a long bias if it breaks out.
