Big-name founders/CEOs trading their own stock (SEC Form 4). Most sells are pre-set 10b5-1 plans (≠ bearish); an open-market buy (code P) is the stronger bullish signal. Research only — not investment advice.

Net insider buying

Net value = insider buy value − sell value over the last ~90 days, from public SEC Form 4 filings. Reflects disclosed activity only, not a buy/sell signal.
