Insider Activity Tracker

Officers, directors, and 10% owners file Form 4 within two business days of executing a trade. Form 144 announces a planned sale 0–90 days ahead — leading indicator for upcoming supply pressure. Discretionary open-market trades are amber-flagged; routine 10b5-1 / sell-to-cover events are noise.

Methodology

Transactions are parsed from the structured XML primary documents at SEC EDGAR for every Form 4 (executed) and Form 144 (planned) filing on Rocket Lab shares. Dollar values use the per-share price reported in the filing × shares; "planned" entries reflect the issuer's stated intent and may differ from the eventual executed price. Open-market sales (`code S`) and purchases (`code P`) carry the strongest signal; grants (`A`), tax-withholdings (`F`), and option exercises (`M`) are routine compensation events and treated as noise.
