And their biggest position, Amarin, could potentially add to their gains in a big way with AdCom next week and potential expanded Vascepa labeling in December. Makes me wonder what is their next big play?

Baker Brothers are about to make a killing on their Amarin stake. According to their most recent filing, they have over 41M at an estimated average price of $8.93. Doing the math makes me sick. I stand to make a lot after the expanded labeling and buyout longterm but nothing like the money they are going to make. Very impressive set of investors.

Sorry....can't get over the fact that they made $1.4 billion in two weeks with their investment in biotech companies.

The other big biotech hedge fund is Perceptive Advisors.

Here's some good info from Fierce about Baker Brothers -

Julian and Felix Baker founded hedge fund Baker Brothers Investments in 2000. According to the earliest available SEC filing for this fund under the same name, they had a mere $256 million at mid-2003. Prior to founding their own fund, they co-founded a biotech investment firm with the Tisch family. The fund is a long-term investor backed by major university endowments and foundations; it focuses on trading in public life science companies.

Felix has a Ph.D. from Stanford University in immunology, while Julian started out in the private equity arm of Credit Suisse First Boston. The pair are both on the board of Genomic Health, Julian since 2001 and Felix since 2012. In 2001, Baker Brothers participated in a $29 million Series B round for Genomic Health alongside Kleiner Perkins Caufield & Byers and Versant Ventures. Felix is also on the board of ag bio company Synageva, where he has been a director since 2000. Julian is also on the board of Incyte ($INCY).
