Methodology & FAQ
How We Track NOC Insider Transactions
Form 4 disclosures are sourced directly from SEC EDGAR and re-ingested on every pipeline cycle. A complete description of transaction-code handling, the open-market vs grant distinction, and the Rule 10b5-1 plan-reference heuristic is documented in the Methodology.
What is an SEC Form 4 filing for NORTHROP GRUMMAN CORP /DE/?
Form 4 is a transaction-level disclosure that corporate insiders (officers, directors, and beneficial owners of more than 10% of a registered class of equity securities) must file with the SEC within two business days of any change in their beneficial ownership of NORTHROP GRUMMAN CORP /DE/ (NOC) shares.
What is a Rule 10b5-1 trading plan?
Rule 10b5-1 is an SEC rule that lets insiders schedule trades in advance under a written plan, providing an affirmative defense against insider-trading allegations as long as the plan was adopted in good faith and not while in possession of material non-public information. Form 4 rows marked "10b5-1" on this page indicate the underlying trade was executed under such a plan; rows without the badge are discretionary or did not reference a plan in the Form 4 footnotes.
How is "insider buying" different from a stock grant or option exercise?
An insider buy (SEC transaction code P) is an open-market purchase of NORTHROP GRUMMAN CORP /DE/ (NOC) stock executed at the prevailing market price using the insider's personal capital. Stock grants (code A) and option exercises (code M) are compensation events, not directional trades; they are tracked separately and excluded from the "conviction" signal because they are not discretionary purchases.
How recent is the data?
Form 4 transactions are typically reported within two business days of execution. Pactolio re-ingests the EDGAR feed on a nightly cycle and reflects new filings on the next ingest run, typically within 24 hours of EDGAR acceptance. The table on this page covers the most recent 1-year window.
