Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of post-acute-care service provider RehabCare Group (NYSE: RHB) zoomed 43% higher today after the company announced it was being bought out by Kindred Healthcare (NYSE: KND). In a rare deal that nearly everyone supports, Kindred's shares even jumped 21% on the news.

So what: Kindred Healthcare will pay $26 in cash and 0.471 shares of Kindred stock for each share of RehabCare. Kindred plans to pay for the acquisition and future growth by taking on around $1.9 billion in financing. The combined company will have a presence in 46 states including 118 long-term acute-care hospitals and 121 inpatient rehab hospitals.

Now what: Usually mergers and acquisitions are viewed as having a winner and a loser, but this time everyone wins. Kindred CEO Paul Diaz said the deal "will be highly accretive," meaning it will add to earnings immediately along with being a long-term strategic benefit. Long term, I love the move for Kindred and think the bigger, more highly leveraged company will provide nice returns to shareholders who decide to stick around.
