The following video is part of our "Motley Fool Conversations" series in which David Williamson, health-care editor and analyst, and Brendan Byrnes, industrials editor and analyst, discuss topics across the investing world.

In today's edition, David and Brendan discuss some of the worst health-care stocks of 2011. These stocks fit relatively neatly into three categories: failure to launch, trial troubles, and home health-care scare. This video focuses on home health-care scare. The home healthcare sector was beaten down mercilessly in 2011 after an already poor showing in 2010. Given a DOJ and SEC investigation over billing practices, negative Medicare changes impacting business, and declining guidance figures, are these business doomed to failure? Or have they gotten so cheap that brighter days for investors are just over the horizon in 2012?
