Your perceptions are right on target with mine regarding your view of ptsc as an investment and the clouds hovering over there...quite convoluted imo.

Seems to be a bit of tax loss selling going on over there right now, trading around .149-.15 currently.

EDIG, on the other hand, seems to have solidified a base around .15-.165 range and sitting with a bullet imo, with a lot of good news going to surface consistently over time.
