PATH($7.22)- Those insider buys must be from the 08/06/2010, the first day PATH traded as an IPO. 08/06/2010, the first day, was the only time the stock hit $10.
Only pretend to put some info, about insider buys.
At the moment i don't have any information with more buys after that days or selling refer!
If they have with avg. $10 i believe during the next month the stock should really start to become more active, with PDUFA date is Aug 29th and near of prices $10!
