RA Capital Management did not report any shares in DYAX and POZN in the third quarter, so these two might be new positions in RA Capital Management’s portfolio. Now RA Capital Management takes 5.29 million shares or 5.36% passive stake in DYAX, and 2.12 million shares or 7.08% passive stake in POZN.

RA Capital Management boosted its stake in SQNM to 5.20%, according to the SEC 13G. As disclosed at the end of September, RA Capital Management had 2.64 million shares in SQNM. So now the firm position is nearly doubled.

In the third quarter, three hedge funds invested in all the three stocks. They are Jim Simons’ Renaissance Technologies, David E. Shaw’s D. E. Shaw, and Israel Englander’s Millennium Management.
