Apple(AAPL Quote) was up 10.5% after reports of brisk sales of the iPhone in the U.K. and Germany where it made its debut over the weekend. China, the world's biggest cell phone market, may be next. An Associated Press report suggested Apple is in talks with service provider China Mobile to introduce the device in China. Shares of Apple were up $16.20 to $169.96 in recent trading.

Chinese search giant Baidu's(BIDU Quote) shares also soared after a positive research note from Citigroup. Analyst Jason Brueschke, who has a buy rating on the stock with a target price of $425, said the recent sell-off in Baidu was overdone.
