Though the small cap market as a whole has been down lately, one sector appears to be rallying and surpassing the others. That’s right – health care companies, a mainstay of small cap indices, is on the rise. Barron’s even called it “the place to be.”

If there’s one sector that’s looking bright, health care is a pretty safe bet. After all, an aging population combined with longer lifespans on average means that more people will be taking advantage of the health care system for quite some time. Over the next 10 years, world demographics will shift such that half of all humans will be over the age of 50.

In the past, we’ve covered health care small cap stocks in groups, but we thought we’d take a different approach and gather a potpourri of health care stocks from a variety of different sectors. While we’ve covered each of these companies before, we’ve never addressed them at the same time. Here’s a short list of small cap stocks in health care that we’ve covered previously:

While we often cover specific industries within the health care sector, health care investors are often concerned with the performance of the market as a whole in addition to specific areas. Investors looking for a market that may continue to show growth for quite some time might wish to investigate the health care industry. After all, it’s looking quite healthy in 2014.
