Frequently asked questions about AIV activity

  • Which institutional owners are buying AIV?

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 AIV activity?

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

  • Is institutional interest in AIV 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.
