  • What does "buy" mean in AVTR activity?

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

  • Is institutional interest in AVTR increasing?
