Frequently asked questions about NDAQ activity

  • Which institutional owners are buying NDAQ?

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 NDAQ activity?

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

  • Is institutional interest in NDAQ increasing?
