Could be, or it could be they tried to start a panic sell to mop up at these prices as it may well never see this range again, at this point it's hard to say, all speculation until results are out, but truthfully if they trade this big without any announcements I think ASIC should start investigations as to why some people had privilege information before the market was notified as if results come out negative it's a little obvious that the people selling new exactly what was going to be announced, I think a shareholder should lodge it and contact ASIC on the matter
