Here I am thinking that Biib's presentation and the news on tysabri about neurologist confidence increasing, the lower PML rate articulated, and the entire facts/spin, however you want to phrase BIIB's presentation on tysabri, along with the recent presentations in other forums on alzheimer, were all working to bring ELN shares back into favor.
Turns out, at least the most likely explanation for recent the share rise, is new rumors of ELN being bought out at 8 euros by a Danish pharma company Lundbeck.
Deja vu to about 2-3 months ago, but then I believe Pfizer was the rumored bidder.
