md, you can remove BMY and AZ from that list. They are targets themselves and whatever they offer for PPHM (if) it would be over-bid because the candidates to buy them will NOT let them get any fatter and have to pay the leverage of the acquisition.
GILD, Roche, Merck, J&J/Janssens, Novartis, etc they have the pockets to buy the above ones and if that would be their intend then BMY and AZ will soon go through a PPS treatment. Starts UP, then boom down and then LID pressure with the profit from the artificial peek/dip.
Peregrine Pharmaceuticals the Microsoft of Biotechnology! All In My Opinion. I am not advising anything, nor accusing anyone.
