I think that speculation and various what-if scenarios do have an impact when there are upcoming binary events. These message boards do have casual visitors, those with large dollars and those without. Besides the casual observers there are also word bots that could easily have picked up on 'large number of dropouts' to make AMRN tank. This is a traders paradise.
This message board is hard enough to read as it is, without having topics and threads and posters that can be easily ignored. I believe that the board going on and on about scenarios where assumptions have turned into facts does shareholders a disservice.
