EA, no offense, but IMO this is one of the most damaging questions that has been repeatedly asked over the last decade or so.  Without referencing any of the Company's fundamental aspects, it implies that the stock will, or should, have a higher price merely because others are choosing to buy it while at the same time paying less.  Yet, as we have seen over this period of time, the price has contined to fall even as the stock has continued to be purchased.

Until fundamental reasons can be cited for assigning a higher value to PTSC, the best answer to this question is probably, "Those who don't know any better".
