Officers, directors, and 10%+ owners have to disclose most trades in their own company's stock within 2 business days — with the actual price paid, something quarterly institutional filings never show. Look up any ticker to see its real transaction history.
An insider buying isn't a strategy on its own. Run your own margin-of-safety analysis on anything you look up here, free.
Methodology: transactions come directly from SEC Form 4 filings. Only genuine open-market purchases are treated as a signal — stock grants, option exercises, and sells are shown for transparency but not highlighted, since routine compensation mechanics and pre-scheduled 10b5-1 sales don't reflect a change in outlook the way a real purchase does.
