Certainly the company can cause a drastic drop if its principals are involved in manipulative trading of the shares, i.e. shorting at the top, buying at the bottom, then pumping it up again!
They can't??? You mean telling us the "drop dead" date for AFs is Nov 15th....then posting that night that they will be up at or before 4am cannot cause a massive selloff??? I beg to differ. Oh yes, combine those two things with the fact that they have been promised many times before THAT, and also a negative news story about the CEO just as icing on the cake. This could very easily have caused the massive price drop. Were there other forces at work??? I cannot say, I just don't know. But my gut tells me no.
