Now that he's taken care of selling ImClone Systems to Eli Lilly
A quick look at Icahn and his fund's SEC filing shows that he's increased his stake in Biogen Idec
Icahn has been pretty clear about his intentions to get Biogen sold to the highest bidder -- even though breaking up the company would be very difficult. It's anyone's guess, but I'd imagine that he's more likely stocking up for another proxy fight than just grabbing cheap shares.
Amylin is an entirely different story. As I said when Icahn originally purchased shares in the diabetes specialist, I have a hard time seeing Icahn getting Amylin sold off. The company is partnered with Eli Lilly to sell its main drug Byetta, and I don’t see anyone getting in a bidding war with Lilly. It's more likely that Icahn sees Amylin as a cheap value play, since potential pancreatitis side effects with Byetta have caused the company's stock to crash in the last few months.
Icahn also opened a position in Exelixis
From Icahn to Buffett, guru investors’ holdings make pretty decent watch lists, but when it comes to an activist investor like Icahn, you also have to try and figure out what his intentions may be. We'll have to wait and see what Icahn does, but my guess is that he keeps badgering Biogen and leaves Amylin and Exelixis alone -- for now.
