Frequently asked questions about AER activity
Which institutional owners are buying AER?
Institutional owners buying AER include investors who have either initiated new positions or increased their existing holdings based on recent SEC 13F filings. 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 AER activity?
"Buy" means an investor increased their reported position in AER compared to the prior reporting period. This reflects growing exposure to AERCAP HOLDINGS NV (AER) rather than necessarily a brand-new position (though new positions also appear as buys when prior quantity was zero).
Is institutional interest in AER 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.
