There are only 2 possibilities that I can think of.
1. PTSC is aware of leakages from within that would provide a heads up for some to trade in Europe ahead of the news here. Perhaps they caught someone and though small potatoes decided to put an end to the possibility.
2. PTSC is not providing any help for Swartz to exit, unless they absolutely have to. The lower price gets him out quicker. But it would seem that they would have started the after-close prs earlier, so ????
What else do we have? Opty
