Monday, December 28, 2020 · Johnny Hopkins

As part of the weekly research here at The Acquirer’s Multiple we’re always interested in superinvestors who hold the same stocks that appear in our Acquirer’s Multiple Stock Screeners, based on their latest 13F’s. Investors such as Warren Buffett, Joel Greenblatt, Carl Icahn, Jim Simons, Prem Watsa, Jeremy Grantham, Seth Klarman, Ray Dalio, and Howard Marks.

While doing this research we’ve also uncovered a number of stocks that superinvestors have sold, or reduced in their portfolios, according to their latest 13f’s. So we’re now providing a new weekly feature article called ‘One Stock Superinvestors Are Selling‘. This week we’ll take a look at:

Biogen Inc (NASDAQ: BIIB)

Biogen and Idec merged in 2003, combining forces to market Biogen’s multiple sclerosis drug Avonex and Idec’s cancer drug Rituxan. Today, Rituxan and next-generation antibody Gazyva are marketed via a collaboration with Roche. Biogen also markets novel MS drugs Plegridy, Tysabri, Tecfidera, and Vumerity. In Japan, Biogen’s MS portfolio is co-promoted by Eisai. Hemophilia therapies Eloctate and Alprolix (partnered with SOBI) were spun off as part of Bioverativ in 2017. Biogen has several drug candidates in phase 3 trials in neurology and neurodegenerative diseases and has launched Spinraza with partner Ionis.

A quick look at the price chart below for Biogen shows us that the stock is down 18% in the past twelve months.
