I don't think it is a matter of information not being released......it went to these prices on the back of the last announcement.....it then looked like the big boys holding the price down to accumulate …..now that they may have got their fill they have released the breaks and the price is rising to where it should be on the back of the last announcement.....if anything this is what should be investigated but this is all IMHO and it appears to happen in every stock.
