NEW YORK ( TheStreet) -- Earnings from Google ( GOOG), Apple's ( AAPL) market cap and a major acquisition by Facebook were the talk of the tech world this week. On Monday, an analyst did the unthinkable (gasp! the horror!) and downgraded Apple, citing concerns about carrier subsidies.
BTIG Research analyst Walter Piecyk cut his rating on the stock on beliefs that partners such as AT&T ( T) and Verizon ( VZ) would rein in iPhone subsidies. "We believe that investors should take a breather during the expected strength of this quarter and the rapid rise in the stock," Piecyk wrote, citing potential changes in the wireless industry. "We expect post-paid wireless operators to remain firm in their plan to stunt the pace of phone upgrades in 2012 and we expect to see some initial evidence of their success in the current quarter." Piecyk downgraded Apple from buy to neutral after shares hit his $600 price target. Despite the downgrade on Monday, Apple continued to chug higher, with the company surpassing $600 billion in market cap for the first time on Tuesday. Shares touched a high of $644 that day, before settling at $628.44. Apple shares have soared since the start of 2012, gaining 49.44%. That outpaces the 15.58% gain seen in the Nasdaq. > >> Bull or Bear? Vote in Our Poll
