Legendary investor Warren Buffett, through his Berkshire Hathaway firm, has almost quadrupled the company's stake in Apple's stock through a shopping binge during the final three months of 2016, according to a regulatory filing.
Buffett has said his company picked up shares of Southwest for the first time last quarter, and Tuesday's filing revealed Berkshire now owns about 43 million shares.
