Frequently asked questions about BMRN activity

  • Which institutional owners are buying BMRN?

The activity table above highlights which funds added shares in the latest reporting periods and how their positions changed over time.

  • What does "buy" mean in BMRN activity?

    "Buy" means an investor increased their reported position in BMRN compared to the prior reporting period. This reflects growing exposure to BIOMARIN PHARMACEUTICAL INC (BMRN) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).

  • Is institutional interest in BMRN increasing?

A higher number of additions typically signals increasing participation among large filers, but it should be read alongside position sizes and the full table.
