Analyst upgrades:

• Morgan Keegan upgraded Marvell Tech (NASDAQ: MRVL) to Outperform from Market Perform based on valuation and sustainable growth.
  
• Merrill upgraded Lehman (NYSE: LEH) to Neutral from Underperform and said the government bailout of the GSE's removes "considerable uncertainty" in the residential mortgage markets and that the housing market is now closer to a bottom. The analyst believes the environment has improved for Lehman to attract equity capital needed and that loss expectations are reflected in valuation.
• Friedman Billings upgraded Zions Bancorp (NASDAQ: ZION) and UCBH Holdings (NASDAQ: UCBH) to Outperform from Market Perform.

Citigroup also downgraded shares to Sell from Buy following the federal government's plan to place the GSEs into conservatorship as they believe both Fannie and Freddie will no longer be managed to maximize common shareholder returns.
  
• Nokia (NYSE: NOK) was cut to Hold from Buy at Deutsche Bank. The firm downgraded shares following the company's guidance reduction and believes the forecast could still be optimistic.
