I've mentioned DVA a few times,  from our Oct. 2, 2012 post "Buffett Bets on the Boomers: End Stage Renal Disease (BRK.B; DVA)":

Around ten years ago a sharp young analyst gave me his five-minute kidneys and dialysis pitch. It made quite an impression on me, I remember it to this day. Unfortunately for him and his firm we were just coming off the Dotbomb crash and everything looked really cheap so I filed the idea under "stuff I'll get to".
Davita is up seven-fold since that day, $103.44 at the close. Fresenius, the largest in the industry is up ten-bagger in ten years, no lost decade there....

After a 2:1 split the stock is at $118 equivalent.
