Executives, directors, and 10% owners disclose their trades within 2 business days on SEC Form 4. Below are the largest open-market purchases from the most recent filings, before the market notices.
This page tracks the largest open-market insider purchases from SEC Form 4 filings across every US-listed company. Only transaction code P (open-market purchase) is included, option exercises, stock grants, and tax-withholding transactions are filtered out because they don't signal a bullish bet.
Insider buying is one of the most watched signals on Wall Street: when officers, directors, or 10% owners spend their own cash to buy shares of their own company, they typically have a bullish view of what's coming. This data is provided by SEC EDGAR and refreshed every hour.
Nothing here is investment advice. Insider buying can be motivated by many factors including tax planning, portfolio rebalancing, or contractual obligations. Always do your own research.
