After President Barack Obama's reelection last night, several of the policies he enacted in his first term will now come into effect as he moves into his second term. No policy is bigger or more polarizing than his Affordable Care Act, colloquially called "Obamacare." And now that Mitt Romney has lost the election, repeal of Obamacare is off the table, and several stocks have made big moves today as a result. The Motley Fool's own health care analyst David Williamson discusses how hospital stocks are poised to gain from this development, and what it will mean for hospitals going forward now that they won't have to carry the debt of the uninsured. However, Medicare reimbursement cuts among other factors means that the health care market news isn't all roses.
