In order for this to run there either has to be a rumor that sparks interest or a concerted effort by a group of investors to put it on the radar by amping up the volume. That is what just happened, a group of investors got together and pumped up the volume, which set off volume and price alerts, which set off the momo-run. I would think that if another group, or even the same group, was going to do that again, they'd wait for the volume and price to drop. JMHO, and yes, I'd love to see PBLS run (actually, it would be great if it had numerous momo-runs from .0001)...
