The Nasdaq fell just shy of an official "correction" between mid-March and mid-April, losing 9.8% of its value during that time frame. Even if that threshold wasn't reached, a number of stocks fell by large margins. When that happens, it's best to have a list of stocks to watch.

The Motley Fool's Brian Stoffel wants to let you know about one stock that's on his list: Catamaran (UNKNOWN:CTRX.DL).  The company's stock hasn't been spared from the recent "correction," with shares trading about 25% lower than their 2014 highs.  But Brian thinks there are three big reasons it's worth looking into this health-care stock now before others realize the value right before their eyes.
