Shares of Supernus (NASDAQ:SUPN) were down 31.5% in November, although the company is still trading at 50% above its IPO price.

Motley Fool health care analyst David Williamson tells us whether he thinks the lower price and potential of its drugs makes Supernus a buy -- or one to avoid at the moment.
