  • What does "buy" mean in PFE activity?

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

  • Is institutional interest in PFE increasing?
