Billionaire activist investor Carl Icahn is done with . 
  
 In an interview with CNBC on Thursday, Icahn said he has unloaded all of his Apple shares, citing concern about the tech giant's challenges in China. 
  
 The 80-year-old investor said the stock is cheap and he still believes Apple is a "great company" and CEO Tim Cook is doing a "tremendous job." 
  
 Yet his fears about China have prompted him to exit the stock. "China obviously could be a shadow for it," he told CNBC, describing concerns about the government telling Apple what it can and can't do. 
  
 Icahn started chipping away at his Apple stake months ago, selling $700 million worth of shares in the fourth quarter of 2015. That still left him with some 46 million shares, equivalent to less than 1% of the company. 
  
 The investment has been a successful one for Icahn. He estimates that he's pocketed about $2 billion in profits and could return for more. "I hope to get back into [the stock] someday," he said. 
  
 Since Icahn announced in a 2013 tweet he had taken a "large" position in the company after speaking with Tim Cook, he has been one of Apple's biggest fans. Last year, he said the company was worth more than $1 trillion, at a time when its market capitalization was $700 billion. He's routinely called the stock undervalued and misunderstood by the market and expressed hope that Apple would make an entrance into television and cars. 
  
 The stock was down nearly 2% following Icahn's comments, after falling 6% yesterday on ugly quarterly earnings. 
  
 Apple has struggled to sell more iPhones and on Tuesday reported its first quarterly sales drop in 13 years. Sales fell all over the world, but dropped an especially steep 26% in China.

The company also manufacturers in China. ||||| NEW YORK (Reuters) - Billionaire activist investor Carl Icahn said Thursday he had sold his entire stake in Apple Inc (AAPL.O), citing the risk of China’s influence on the stock.

 Icahn, in an interview with cable television network CNBC, also said he was “still very cautious” on the U.S. stock market and there would be a “day of reckoning” unless there was some sort of fiscal stimulus. 
  
 Icahn had been a huge cheerleader of Apple, acquiring a stake in the company almost three years ago, repeatedly calling the investment a “no brainer.” 
  
 In an open letter to Apple Chief Executive Officer Tim Cook in May 2015, Icahn had argued that shares of the iPhone maker were worth $240, about 90 percent more than they had been trading. At $240 a share, Apple’s market cap would be $1.4 trillion, Icahn asserted. 
  
 But Icahn, who owned 45.8 million Apple shares at the end of last year, said China’s economic slowdown and worries about how China could become more prohibitive in doing business triggered his decision to exit his position entirely. 
  
 “We no longer have a position in Apple. Tim Cook did a great job. I called him this morning to tell him that and he was a little sorry, obviously. But I told him it’s a great company,” Icahn said. “In Apple today as opposed to six months or a year ago, in this one, there’s no need for activism because I think they have a great management. But you worry a little bit, maybe more than a little, about China’s attitude.” 
  
 The Chinese government could “come in and make it very difficult for Apple to sell there ... You can do pretty much what you want there,” Icahn said. Earlier this month, China shut down Apple’s iTunes movies and iBooks stores within the country, following Beijing’s introduction of regulations in March imposing strict curbs on online publishing, particularly for foreign firms. 
  
 Asked when he might get back in, Icahn replied: “I don’t think it’s the price point. I think it’s my opinion about what is happening with China. I think the stock is very cheap on a multiple basis. China could be a shadow for it, and we have to look at that.” 
  
 Icahn, who suggested that he made roughly $2 billion off the Apple trade, said he was in Apple for about three years and “if you bought the stock then, you got a 48 percent to 50 percent total return. We obviously made a great deal of money, but it was no surprise that we got out of some in February.” 
  
 Apple shares came under further selling pressure during Icahn’s television interview, as did the Dow Jones industrials with Apple closing down over 3 percent at $94.83. The Dow ended down by 210 points. 
  
 Apple on Tuesday posted its first decline in iPhone sales as well as its first revenue drop in 13 years. The company’s sales fell by more than a quarter in China, its most important market after the United States, and it forecast another disappointing quarter for global revenues. 
  
 Apple shares have now declined more than 10 percent this week. ||||| Chinese customers of Apple's iTunes Movies and iBooks services are seeking refunds on their purchases amid reports that the features have been suspended at the behest of government authorities. 
  
  
  
 Apple has not issued any statement to customers in China about the status of the services, but many users report that they have been unable to connect to the movie service and iBooks since April 15. 
  
  
  
 A Beijing-based Apple spokeswoman said: "We hope to make books and movies available again to our customers in China as soon as possible," but she would not elaborate on why the services were unavailable. 
  
  
  
 The Chinese government has not issued any statement on the matter. However, the New York Times, citing two anonymous sources, said the State Administration of Press, Publication, Radio, Film and Television had ordered the services offline, though it was unclear why. 
  
  
  
 Apple's App Store revenue has surged in China in the last year, overtaking Japan as the world's No. 2 market for the service, according to App Annie. 
  
  
  
 Apple technical assistance and account service representatives, reached by phone in China, said they had received no official notice from the company that the services had been blocked or shut down. They offered to arrange refunds on purchased content. 
  
  
  
 "The iTunes Store's movie service is turned off," one customer wrote on the Twitter-like service Sina Weibo. "I spent 88 kuai [about $13.50] buying a 'Star Wars' collection and have not had time to download it. I want know if I can get a refund or not." 
  
  
  
 China has become a massive market for Apple since the Cupertino, Calif. company launched the iPhone on the mainland in 2009. In its fiscal year ending in September 2015, the company said total net sales increased 84% year-over-year in Greater China to $58.7 billion. (Greater China includes mainland China, Hong Kong and Taiwan). 
  
  
  
 Apple is one of only a handful of U.S. tech companies that have flourished in China. 
  
  
  
 Facebook and Twitter have been blocked by Internet censors for years. Google pulled its servers out of China in 2010 because of censorship. And Amazon has struggled to gain traction in the country against local rivals such as Alibaba. 
  
  
  
 The government in Beijing has moved to rein in foreign technology companies — at times demanding to add backdoors to hardware and urging data be stored on local servers. Apple said it has never provided a backdoor to Chinese authorities, but it agreed to store user data locally. 
  
  
  
 Now that millions of Chinese own Apple hardware, the company has set its sights on selling them content and services. On Sept. 30, Apple launched its music service, as well as iTunes Movies and iBooks in China. The company in February introduced Apple Pay in China as well. 
  
  
  
 The iTunes movie service enabled fans to rent or purchase movies from Chinese studios as well as Hollywood blockbusters. A variety of free and paid books also were made available on iBooks. Rentals of high-definition movies on iTunes started at about 77 cents, and purchases at $2.77. Paid iBooks started at about 8 cents. 
  
  
  
 "For the first time, customers in China will have access to Apple's entertainment ecosystem with music, movies and books right at their fingertips," the company said in a statement announcing the September launch. 
  
  
  
 Eddy Cue, Apple's senior vice president of Internet Software and Services, added at the time: "Customers in China love the App Store and have made it our largest market in the world for app downloads. One of the top requests has been more great content, and we're thrilled to bring music, movies and books to China, curated by a local team of experts." 
  
  
  
 To encourage Chinese customers to start using iTunes Movies, Apple offered free rentals of the hit Chinese film "The Taking of Tiger Mountain" for a limited time. On the books front, Apple touted its selection of Chinese books and foreign novels, noting that it was bringing Stephenie Meyer's "Twilight" series to China for the first time in a digital format. 
  
  
  
 Apple Chief Executive Tim Cook took to Weibo on the day of the launch, telling Chinese customers: "Excited to launch Apple Music, iTunes Movies and iBooks in time for you to enjoy over the October holidays!" China celebrates its National Day on Oct. 1. 
  
  
  
 So far, Cook's Weibo account has been silent about the services' suspension.

Output:
Just a few years ago, Carl Icahn opened his wallet to invest in Apple, calling such a move a "no-brainer," and became what the Guardian calls a "huge cheerleader" for the tech company. But that all changed this week as the billionaire investor made a decision to dump his entire stake, citing interference from China—Apple's second-largest market—and worries that the country would keep putting up barriers to Apple doing business there. (One such barrier: China "mysteriously suspended" the iTunes movies and iBook stores earlier this month.) "They're basically … a benevolent dictatorship," he said, though "I don't know if benevolent is the right word." And so "we no longer have a position in Apple," Icahn said in a CNBC interview Thursday, per Reuters. "Tim Cook did a great job," he continued. "I called him this morning to tell him that and he was a little sorry, obviously. But I told him … it's a great company." Forbes notes that Icahn's trade wasn't a total shock, as he had started getting rid of large chunks of shares last year (he sold off $700 million worth of shares late last year). What he just sold off amounted to a nearly 1% stake, per the Los Angeles Times. The 80-year-old said he made about $2 billion on Apple. But is he out for good? Icahn said he'd get back into Apple if China "basically steadied." (Apple this week experienced a drop in quarterly revenue for the first time 13 years.)
