About Insider Buying

Insider Buying helps everyday investors follow the smart money. When corporate executives and directors buy shares of their own companies on the open market, they file a Form 4 with the U.S. Securities and Exchange Commission (SEC). We collect those filings the moment they hit SEC EDGAR, structure them, and turn them into clear, actionable signals.

At the heart of the platform is our proprietary Insider Score — a 0–99 measure that weighs purchase size, buying clusters, the role of the insider, and conviction, so you can instantly see where insiders are putting their own capital with the most confidence.

What we do

• Track every open-market insider buy and sell from SEC Form 4 filings.
• Score and rank companies by insider conviction with the Insider Score engine.
• Surface live market data — heatmaps, gainers, dividends, analyst ratings and more.
• Publish plain-English research and daily AI briefings on the biggest insider moves.

Where our data comes from

Our insider data is sourced directly from SEC EDGAR. Market prices, market caps and volumes come from live market-data feeds, and we cross-reference macro data from the Federal Reserve, U.S. Treasury and other public sources. Everything is refreshed throughout the trading day.
