Frequently asked questions about NOC activity

  • Which institutional owners are buying NOC?

    Institutional owners buying NOC 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 NOC activity?

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

  • Is institutional interest in NOC increasing?
