Frequently asked questions about MAC activity

  • Which institutional owners are buying MAC?

    Institutional owners buying MAC 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 MAC activity?

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

  • Is institutional interest in MAC increasing?
