CNBC reports that when asked about volatile Chinese stocks, investing legend Warren Buffett said Saturday that markets can sometimes resemble a "casino." The Oracle of Omaha offered advice to the world's second-largest economy, which in recent years has struggled to manage the fallout from an economic slowdown. Chinese authorities have imposed capital controls, and tightly manage the levels of its currency, the yuan. "Early on in the development of markets there's probably some tendency for them I think to be more speculative than markets that have been around for a couple hundred years," Buffett said, in response to a Chinese investor's question. He was speaking at the Berkshire Hathaway annual shareholders meeting. "Markets have a casino characteristic that has a lot of appeal to people, particularly when they see people getting rich around them," Buffett said. "And those who haven't been through cycles before are more prone to speculate than people who have experienced the outcome of wild speculation." The New York Stock Exchange launched in the late 18th-century. In contrast, the Shanghai Stock Exchange opened in 1990.
