There have been some interesting upgrades in technology stocks this morning. It wasn't so much a goal of analysts trying to mark the bottom on yesterday's sell-off, but these appear to be on valuation. Apple Inc. (NASDAQ: AAPL) was raised to Buy from Hold over at Gabelli after the recent sell-off looks excessive. Shares are up over 3% at $108.90, but we'd note that shares were down almost $23.00 yesterday. ARM Holdings (NASDAQ: ARMH), the British communications chip company, was raised to Buy from Neutral at Goldman Sachs. Shares are up over 2% at $5.26, although this one is fairly thin trading volume. Intel Corporation (NASDAQ: INTC) is up 4% on a call out of Piper Jaffray. The firm raised its Neutral rating to a Buy rating with a $22.00 price target. Research in Motion (NASDAQ: RIMM) is up over 4% at $64.50 after JMP Securities took its Market Perform rating up to an Outperform rating. Jon C. Ogg September 30, 2008 ...
