Its partly based on e-wave as well Zeev, your favourite-g. But basic TA has the choppy mess since early December as nothing more than a bear flag for now.
As for AMGN it appears to be breaking down from a large wedge going back to September, so I have it on breakdown alert although it hasn't moved yet.
And the BTK is up against the top of its large triangle out of the July low, if we go higher I too will be bullish on the bios as it would be a breakout. But as it is I see a possibility that the triangle consolidation there may be complete and we will begin to break down. Early days yet and nothing techinically damaging has actually occured to any bios including IDPH but there is some very bearish scenarios which are set up, whether or not they follow through is another matter.
