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 hospital operators Vanguard Health Systems (NYSE: VHS), HCA Holdings (NYSE:HCA), Tenet Healthcare (NYSE:THC), Health Management Associates (NYSE: HMA), and Community Health Systems (NYSE:CYH), soared 16%, 10%, 10%, 10%, and 14%, respectively, following the re-election of President Obama.

So what: As I mentioned earlier in the week, hospitals definitely had the most at stake in last night's elections. President Obama's bill, the Affordable Care Act, is going to make it a requirement for all Americans to carry insurance, which should reduce and potentially eliminate the bad-debt provision that all hospitals currently count as losses for patients who are unable to pay their bill. With Obama's re-election, it seems ever more likely that the ACA will go into effect in 2014 without a hitch.

Now what: I'm not sure I'd chase after hospital stocks after a big rally like the one we're witnessing today, but it's definitely another step in the right direction for the sector as a whole. None of these companies is particularly expensive on a forward earnings basis, but it's going to take some time to remove those bad losses from hospitals stocks' bottom-line results, so keep your expectations in check.
