SGE:
I believe you are correct in your assumption. regarding the 9.99% threshold for Swartz. As was mentioned before, this is Swartz's problem not PTSC's to maintain below the 9.99% threshold. I do suspect from time to time, Swartz crosses that boundary for a few days or even weeks, but likely manages to get back under the 9.99% before the end of each reporting month.
Regarding resistance, given the relatively consistent low dollar volume, and the number of MM's there are, Swartz selling of even 300-400k shares daily would move the price measurably.
