Health-insurance stocks have been under a lot of pressure recently. Though fourth-quarter results weren't great for many, the downward pressure can be much more closely attributed to several CEOs in the industry showing grave concern for larger-than-anticipated Medicare cuts. The cuts were expected to be in the 3%-4% range, but large insurers had reached the point of expressing fear over much steeper cuts of 6%-7%. Today came the moment of truth, with the cuts falling in line with original expectations, at 3.55%.

In this video, Motley Fool health-care analyst David Williamson takes a look at which of the large insurers are the most exposed to Medicare Advantage, and which are benefiting the most from the lower-than-expected cuts today.
