Berkshire Hathaway Inc. has been buying Amazon shares and the purchases will show up in a regulatory filing later this month, Buffett told CNBC in an interview Thursday. Buffett, Berkshire’s chairman and chief executive officer, said “one of the fellows in the office that manage money” made the purchases, a reference to investment managers Todd Combs and Ted Weschler.
Combs and Weschler have gained influence at Berkshire in recent years. Buffett credited some of his conglomerate’s purchases of airline stocks and Apple Inc. to the deputies and noted their involvement in helping Berkshire beyond their stock-picking duties. Buffett, 88, and long-time business partner, Charles Munger, 95, have praised the pair, with Munger saying they give Berkshire “younger eyes.”"
