  • What does "buy" mean in ANAB activity?

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