Frequently asked questions about HEI-A activity

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 HEI-A activity?

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