Warren Buffett mostly tweaked around the edges of Berkshire Hathaway's (BRK.A) Q4 holdings, but the firm bought 2.7M shares of Davita (DVA), which runs dialysis centers, and 1.7M shares of Liberty Media (LMCA), a communications and entertainment company. It raised its stake in DirecTV (DTV) to 20M shares from 4.2M.
