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 AORT activity?

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

  • Is institutional interest in AORT 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.
