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.

It's good to see that Pentastone Electronics has rewarded shareholders with a total shareholder return of 141% in the last twelve months.
