There are some big blocks coming out, 30K,30K, 18.5K. This appears to be some of the settlement money. Could be AQ itself, more likely they had to pay debts, law fees (remember they asked for stock in 50K certificates which means they need to sign some or many of those over, they may have borrowed money to continue the fight?) and those guys are likely selling. Don't expect it to last too long. PERT may be the MM for the seller or sellers, can't tell yet.
