Healthcare is a trillion-dollar industry in America alone, and the opportunities for investors to profit from it are absolutely incredible. However, the complexity of technical information (i.e., hard to pronounce drug names) and significant downside risks (i.e., failing an FDA approval) have led many investors to avoid the space entirely.

In the following video, Rule Breakers analyst Simon Erickson and healthcare analyst Michael Douglass introduce three fast-growing healthcare companies that don't require a PhD to decipher. Veeva Systems (NYSE:VEEV) is optimizing the way new drugs are brought to market, Athenahealth (NASDAQ:ATHN) is making hospitals more efficient, and Catamaran (UNKNOWN:CTRX.DL) is bringing down costs of the entire healthcare system. In the video, our analysts reveal what they believe makes each of these businesses so special.
