In an SEC Form 4 filing after the market closed today, Berkshire Hathaway revealed that it added 286,000 shares of kidney dialysis company DaVita (DVA) between October 9 and October 12 at prices as high as $111.21. DVA’s closing price on October 12 was $110.42. Berkshire’s stake is currently valued at $1.2 billion and represents 11% of DVA.
Ted Weschler, who joined Berkshire in early 2012 as a portfolio manager, apparently purchased these shares. Mr. Weschler’s hedge fund, Peninsula Capital, held a substantial position in DVA from 2003 – 2011. DVA was consistently one of Peninsula Capital’s three largest investments over this time period.
