MOST NOTEWORTHY:

• Wachovia upgraded Goldman Sachs (NYSE: GS) to Outperform from Market Perform, as they believe Goldman has a superior capital position relative to competitors and will likely benefit more than any firm from Bear Stearns' (NYSE: BSC) collapse. They have a $180-$185 target range for the stock.
  
• Following Alexza Pharma's (NASDAQ: ALXA) Q4 report, JMP Securities said they have reduced concerns regarding Loxapine timelines and risks. The firm raised Alexza to Outperform from Market Perform.
  
• SAP AG (NYSE: SAP) was upgraded to Outperform from Market Perform at Bernstein on valuation and a positive view on fundamentals.

• Tyson Foods (NYSE: TSN) was raised to Overweight from Equal Weight at Stephens.
• Citigroup upgraded Teekay Shipping (NYSE: TK) and General Maritime (GMR) to Buy from Hold.
  
• RiskMetrics (NYSE: RMG) was upgraded to Buy from Neutral at Banc of America.

With the turbulence in the markets, it was looking dicey for the RiskMetrics Group (NYSE: RMG) IPO. The company even priced its offering at $17.50, at the low end of its proposed $17-$19 range.

But RMG turned out to be a good deal for investors. RiskMetrics' stock price is now trading at about $23.

The company is the brainchild of JPMorgan (NYSE: JPM), which wanted to develop better ways to deal with risk. After all, the financial markets have become increasingly complicated – especially with the surge in derivatives.

To bulk things up, RiskMetrics purchased ISS, which provides research and voting services for corporate governance.

The upshot: RiskMetrics has about 3,500 customers. Revenues increased about 16% to $176 million for the first nine months of 2007.

However, perhaps the biggest boost for RiskMetrics came from announcement that Societe Generale lost $7.1 billion, which was the result of a nefarious trader. No doubt, the firm could have used some better risk management systems, huh?

The underwriters on the RiskMetrics IPO included Credit Suisse, Goldman Sachs and Banc of America Securities LLC.
