Marriott ( MAR) downgraded to Underperform at Oppenheimer from perform and price target increased to $16 from $13. Downgrade based on three points: 1) OpCo does not expect that MAR will be able to pay down as much debt as it expects this year; 2) Lodging fundamentals have not indicated improvement to date and are more challenging in 2H09 an 2010, albeit at a lower negative growth rate; and 3) The run-up in the shares as well as the premium valuation compared to the group appear to be unwarranted.

RIM ( RIMM) Upgraded to Buy at Citigroup to buy from hold and price target increased to $100 from $65. Citi expects focus will shift over next few qtrs back to RIMM's unit growth rather than gross margins. RIMM's aggressive promotions (BOGO) open new consumer adoption & accelerate "Smart Becomes Average" view of mainstream adoption vs. former high-end/niche. Enterprise stabilizing & regulatory changes (Mass state encryption) also small help to enterprise units.
