SAN FRANCISCO -- Apple Inc. shares fell the most in more than a year amid concerns about Nokia Oyj getting a leg up in China and traders betting that a recent rally may have sputtered.
Apple was down 4.4 percent to $550.37 as of 1:28 p.m. in New York, after falling as much as 5.3 percent, the most since Oct. 19, 2011. The stock has advanced 42 percent so far this year through yesterday.
China Mobile Ltd., China's largest wireless carrier, agreed to carry the Lumia 920T, a device based on Microsoft Corp.'s Windows Phone 8 software, the companies said in a statement today. While Apple has agreements with China Telecom Corp. and China Unicom (Hong Kong) Ltd. to sell iPhones, the Cupertino, California-based company hasn't yet forged a deal with China Mobile in the world's largest mobile-phone market.
"Nokia announced that they are launching one of their Lumia phones with China Mobile, and there was some hope that Apple would launch their iPhone on that network," Gus Papageorgiou, an analyst with Scotia Capital Inc. in Toronto, said in an interview. "I think they still will, but they'll probably launch closer to Chinese New Year."
China's 2013 lunar new year begins Feb. 10.
Apple's slide also may be the result of traders predicting a drop after the stock failed to sustain a recent rally, a "classic technical breakdown," according to Gene Munster, an analyst with Piper Jaffray Cos.
Munster said new so-called margin rules also may have been put in place by some investors that could limit how many Apple shares a firm can own. Investors may also be disappointed Apple isn't issuing a special dividend like Oracle Corp., Wal-Mart Stores Inc. and other U.S. companies, he said.
In another announcement that may be contributing to the share slide, research firm IDC said in a report today that Apple's share of the tablet market will slip to 53.8 percent this year from 56.3 percent in 2011, while Google's portion will advance to 42.7 percent from 39.8 percent. Apple's tablet share will slip below 50 percent by 2016, as total global tablet sales more than double to 282.7 million units in four years as consumers increasingly shun personal computers, according to IDC.
