US tech giant Apple lost about 190 billion dollars in market value over two days as reports of iPhone restrictions in China caused its shares to plunge.
The stock fell 2.9 percent in New York on Thursday, following a 3.6 percent tumble the day before.
The declines came after the Wall Street Journal and other media reported that the Chinese government ordered its officials not to use iPhones for work or bring them into their offices.
China is one of Apple's main markets, accounting for about 20 percent of its global sales.
