I believe PTSC and EDIG both have spike potential within the next month. With PTSC there is the remaining possibility that Swartz will kill it. However, I have another worry. Trading in these stocks seems to be done though a handful of online brokers who also act as market makers. It seems to me that when volume surges these brokers/mm's quickly develop naked short positions and they have the ability to dampen or quell demand by requiring all trades go though a broker ( at a snails pace). That cost me considerable profit in the last move with PTSC but the same thing happened with EDIG. Etrade still has constraints on PTSC but neither Etrade nor TDAmertrade have any restraints on EDIG for the present. It ought to be illegal to change the rules in such an obviously self serving way.
