Analyst upgrades: UBS, CPHD and ICTG

MOST NOTEWORTHY: UBS AG, Cepheid and ICT Group were today's noteworthy upgrades:

• Credit Suisse upgraded shares of UBS AG (NYSE: UBS) to Outperform from Neutral on valuation, as they believe the current share price implies a negative valuation of the company's securities unit.
• Piper upgraded shares of Cepheid (NASDAQ: CPHD) to Buy from Neutral to reflect the better-than-expected quarter to date GeneXpert placements and management's bullish outlook during their Annual Health Care Conference.
• ICT Group (NASDAQ: ICTG) was upgraded to Market Perform from Underperform at Friedman Billings following the company's reiteration of guidance last night. The firm believes shares are near a floor and that the company could be an attractive takeout candidate once business stabilizes.
