Dropped 31.56% Friday. $5.03. Closed at 10.91. Rosen needs to be in jail and the laws changed. I don't care how this company is performing, targeting companies to fail with accusations and profiting from it shouldn't be legal. They must have a hidden trading and that needs to be exposed and face the courts system.
