i wouldn't short nas, rather looking for buy opportunities, in 2 days there is the famous fed talk about the fkng tapering, i think that even if they announce it, it will just be a good BT(F)D opportunitie: tapering means easing of QE not that they will suddenly stop their brrrr damn thing. something to be looking at is nasdaq divided by M2, i think it will double top with the dot com bubble top, but that's a story for another idea, mean wile just be careful bears. trade what you see not what you would like to happen.
