Sdr, re manipulation: look at the charts for ibzt, ptsc and pcbm. Notice they are all unrelated yet spiked heavily at the same time last april. What could have caused this? Anticipation of an upcoming rules change? I wont even go back and read any posts from any of their respective message boards either. It would be too painful. "Investors" probably thought they were on the edge of a bubble renaissance and added to their positions on the way back down.
