Some PPS volitility is to be expected with any pinksheet company. Especially one that is subject to pumpers and dumpers. Most companies trade on news or rumors. If the news is good, PPS goes up, if the news is bad, PPS goes down. If the PPS goes up without a reason, then it is only logical to conclude that the increase is due to daytraders who are looking to make a quick buck. I have been with this company for almost 2 years now. Got in at .14 then added along the way (basis is now .27). I've seen this stock fluctuate up and down for no reason many times. However, when good news is posted, the market has always responded favorably. For the long-term investor, riding the wave is just part of it.
