IMO...This stock will go up much more when its recognized as a player in the field. It never really has been, and for a short while it was a few years ago, all confidence was squandered pretty quickly. That's why the Nicholson news was so important, as well as the signing on of McNally as legitimate player as opposed to previous management.
It's also the financing or dilution still needed, which I always thought was the principal factor in suppressing PPS, but since McNally has made some very positive changes, I think the above is actually the bigger factor here.
There's also some other important upward momentum that's easily forgotten, which is that we're getting pretty close to FDA submission, and it's starting to look like they will make it according to timeline. In 2014, that anticipation led to a fivefold increase in PSS over one year, despite dilution happening at the time, and without any real news (or visible product).
That could easily happen again provided they make the timelines and confidence increases in that period. So, a much higher PPS over the coming year seems quite feasible to me despite dilution, because this time there's so much more supporting this stock (like an actual product that is well-received)
