  • 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).
