The most famous and successful investor in the world is Warren Buffet, and his company Berkshire Hathaway Inc now owns 15% of DaVita, reported on many financial web sites this week. As more people are given dialysis, obviously his company see this as a good investment.
According to the Davita web site, as of September 30, 2012, DaVita operated or provided administrative services at 1,912 outpatient dialysis centers located in the United States. Plus 24 centers in other countries. Not bad for a company that was founded in 1999. That sort of growth must be what attracted Buffet's company to regularly buy shares in the company.
