While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over the last twelve months, Jazz Pharmaceuticals actually shrank its EPS by 53%.

This means it's unlikely the market is judging the company based on earnings growth. Therefore, it seems likely that investors are putting more weight on metrics other than EPS, at the moment.

However the year on year revenue growth of 9.3% would help. We do see some companies suppress earnings in order to accelerate revenue growth.
