I guess we can assume that the roadshow will generate awareness at potential investors. These investors have no PTK shares in their portfolio. I can see three different kind of investors:
(A) Some will build first positions in the open market, driving the SP slowly up - good.
(B) Some will try to play tricks to do the same, trying to short, so scare old investors as well as (A) out of their position, trying to drive the SP down: bad and ugly.
(C) Some will be not interested, or can not invest due to a lot of factors: neutral for the moment, good or bad - lateron.
My idea is that it will not be that easy for investor (B), as (A) is not that stupid as some retail investors. Finally (A) and (B) are very similar, possibly the same, we should not care, as
1. It will be not that easy to scare (A), as (A) knows all these tricks, and
2. (A) will use opportunities of building up volume in the bid to harvest them. There will be a competition between (A) and (B). But as both have the target to buy shares, all this finally should move the SP north.
So let us stay calm, and as always - patient.
