Today's action dictates that approval must be close and, that some important funds want shares.
A connected friend will trigger a slide in the shares by placing a huge sell order, this sale order will trigger stop losses creating illusion of a panic, meaning huge firm gets to load up.
Firms usually do this when they are fed up and want in or, know that approval is close. On DNDN these firms pulled out a beauty, they made everyone sell from $ 22 to $ 7 in minutes, then halted and next day open at $ 22 with new owners. Talk about raping the little guy.
