The Affordable Cara Act, a.k.a. Obamacare, is dramatically changing the economics of the hospital industry. Because of that transformation, we're seeing some large mergers and acquisitions as companies seek to gain the size to profit in this Obamacare world.
First, Tenet Healthcare purchased Vanguard at a 70% premium, becoming the nation's second largest publicly traded operator in the process. Tenet's CEO wanted to let it be known that purchasing Vanguard wouldn't stop it from pursuing other deals despite its size.

In this video, health-care analyst David Williamson discusses what these events mean for investors in the hospital sector, why they should expect the dealmaking to continue, and what his favorite hospital stock is.
