They already have a large stake here..
Sentiment: Strong Buy
They have a small stake, as a number of pharmas have with various microcaps. They're not about to buy an unproven science. And if MultiStem is turns out to be half as good as hoped for, Athersys would be nuts to sell.
C'mon, you are not me. Not even close.
BTW, this goes up tomorrow. And will be up big!!! JMHO
Athesys buying Pfizer would be a very positive development.
