$heff's $tation of $tocks & $olid DD

[RealGenius]

OT: Drop on positive news. I have been watching this also, with big board biotechs I've played recently separate from those listed or discussed on Sheff's board.

I am nervous this is an indication the bull market is over. Overhyped speculation during the run up but no continuation on positive news. Does this mean its all traders and no fundamentalists; big funds not seeing any fundamental increase in value after approvals, because the shareprice has already been overextended by enthusiastic retail traders?
