Buffett likes Amazon and dislikes Walmart. Something that a lot of us stock geeks overlook is that Buffett has been bullish on Amazon for a long time. Uncle Warren has never been fond of the Everything Store’s stock, but he’s been investing in the company’s debt for a long time. He bought $98.3 million worth of its junk bonds back in 2003. Therefore Buffett was an Amazon bull long before it was fashionable. He’s also on record as a Jeff Bezos fan.
