Insider Stock Watch is an educational and research tool. It helps you explore public information about insider buying. It isn't investment advice.

Not investment advice
Rankings, scores, lists, signals, charts and suggested hold periods on this site are general information generated automatically from public data. They don't take your personal finances, goals or tolerance for risk into account.
We are not a registered investment adviser, broker-dealer or financial planner, and using this site doesn't create an advisory relationship. Labels such as "buy list", "HOLD" and "SELL" describe what a rule or model shows, not a recommendation for you. Consider talking to a qualified professional before making investment decisions.
Where the data comes from
Insider trades come from SEC Form 4 filings, collected through OpenInsider. Prices and headlines come from Yahoo Finance, and company filings from SEC EDGAR. We work to keep this information accurate and up to date, but third-party data can be delayed, incomplete or corrected after the fact, and rankings are refreshed once a day. You can always check the original filings on SEC EDGAR.
About scores and models
Scores and model estimates summarize how unusual insider buying is and how similar situations played out historically. They are estimates, not predictions or guarantees, and markets can move for reasons no model anticipates.
Past performance
Performance figures on this site come from backtests: simulations that apply a strategy to historical data. They are hypothetical, don't reflect actual trading, and don't account for every real-world cost such as taxes, fees and the difference between quoted and actual trade prices. Past performance doesn't guarantee future results.
Investing involves risk
All investments carry risk, including the possible loss of the money you invest. Only invest what you can afford to lose, and do your own research before acting on anything you read here.
Your positions
If you record positions, their status, hold periods and sell dates are worked out with the same data and rules described above. They are reminders based on a general plan, not an assessment of your situation.
No warranty
The site and its data are provided "as is", without warranties of any kind. We aren't liable for any loss arising from your use of, or reliance on, information on this site. Investment decisions are your own.
