PTSC has not yet been able to demonstrate the potential (EPS) we believe is out there. News releases never report income, and the Jan 16th Q Report is not likely to reflect good EPS for the Sept-Nov period (5 licenses). Conclusion: SP is about right - just look at the P/E.
I believe something like this might help if issued with the 10Q:
