MOST NOTEWORTHY: Allegheny Tech, Carpenter Tech, Haynes, Motorola and Machinery stocks were today's noteworthy downgrades:
- JP Morgan downgraded Allegheny Tech (NYSE:ATI), Carpenter Tech (NYSE:CRS) and Haynes (NASDAQ:HAYN) to Neutral from Overweight based on the decline in nickel prices and its impact on nickel-based metals demand on valuation, as they find the risk/reward less attractive following the recent rally and increased raw material costs.
- Oppenheimer downgraded shares of Motorola (NYSE:MOT) to Underperform from Perform after channel checks indicated the company could miss Q2 handset guidance and continued market share losses.
- UBS said the risk/reward profile for owning Machinery stocks given macro challenges and valuations. The firm downgraded Caterpillar (NYSE:CAT) and Kennametal (NYSE:KMT) to Sell from Neutral and United Rentals (NYSE:URI) and RSC Holdings (NYSE:RRR) to Neutral from Buy. Additionally, shares of Paccar (NASDAQ:PCAR) were cut to Sell from Neutral and Navistar (OTC:NAVZ) was downgraded to Neutral from Buy due to weak U.S. truck demand.
