In Forms 3 and 4 filed with the SEC today, Warren Buffett's Berkshire Hathaway has disclosed an increased position in DaVita (DVA).

Per the filing, Berkshire now owns over a $1 billion stake with 10,197,569 shares (or over 10% of the company).  The filings disclose Berkshire purchased 282,403 shares at weighted average prices ranging from $100.96 to $103.7272 between September 26th and 28th.

In the most recent issue of our Hedge Fund Wisdom newsletter, we highlighted how Berkshire had boosted its stake in DVA by 55% during the second quarter and noted that it is portfolio activity most likely attributed to new portfolio manager Ted Weschler.  DVA was one of Weschler's big holdings at his previous hedge fund.

Additionally, our premium newsletter flagged that DVA was a consensus buy among hedge funds in Q2.  Other top holders at the end of Q2 included Viking Global, Lone Pine Capital, Pennant Capital and more.

Per Google Finance, DaVita is "a provider of dialysis services in the United States for patients suffering from chronic kidney failure, also known as end stage renal disease (ESRD)."
