We bought a little more: Buffett on Berkshire's $56bn Apple stock
Warren Buffett, who turned 88 on Thursday, said his firm Berkshire Hathaway has bought "just a little" more of Apple stock. Berkshire, which already owns 252 million Apple shares worth $56 billion, also bought back its own stock for the first time since 2012. "I don't know when to buy stocks, but I know whether to buy stocks," he added.
