Plenty of health-care stocks hit major headwinds this week. Few were blown away like these three, though.

One of this week's major losers disappointed investors with mid-stage clinical results. Another had some big news that didn't seem to move shares much, but the broader sell-off on Thursday shook the stock in a big way. The third didn't have much news at all to speak of, but a general perception that it's overvalued combined with the larger trend working against health-care and technology stocks appear to have dealt this stock a double-whammy.

Which stocks were the most horrendous in all the world of health-care? Find out by watching the following slideshow.
