Short-sellers -- investors who bet that Amylin shares would fall -- are positively giddy and making money. Amylin shares are down $10.35, or 50%, to $10.14 in Wednesday trading.
How did the shorts get Amylin right when a majority of investors believed Bydureon was going to be approved? I spoke with one Amylin short early Wednesday about his bear thesis. This hedge fund manager asked to remain anonymous because the rules of his fund forbid him to speak publicly about his investments.
"I always believed that Amylin and Eli Lilly (LLY) were taking shortcuts to get Bydureon through the FDA" and the agency was going to have problems with this approach, said this short seller.
