Open enrollment for most people in the public exchanges created by the Affordable Care Act, better known as Obamacare, has ended. The final enrollment numbers, including people who have an extension for the next 60 days, are not yet available, but we already know that the public exchanges enrolled more than 7 million Americans, far more than expected. This number is in addition to the millions of Americans who have newly enrolled in Medicaid thanks to Obamacare's Medicaid expansion and people who purchased insurance individually or on private insurance markets in response to the Obamacare individual mandate.

In the video below, excerpted from Friday's market checkup, Motley Fool health care analysts David Williamson and Michael Douglass discuss the newest Obamacare news, what data investors should focus on as it becomes available, and the stocks most poised to benefit from the increased enrollment. This story will continue to develop over the next months, so stay tuned for more information as it becomes available.
