When it comes to investing, insider data matters.
Harvard Business School research found that insiders’ opportunistic trades beat the market by 82 basis points a month.

Why insiders
What’s included.
Insider Scores
A 0–100 score on every company with qualifying open-market buys, with the pillars behind it.
Top Insider Buys
Every purchase graded A+ to F as the Form 4 lands — size, stake growth, buyer record, timing.
Top Analysts & Insiders
People ranked by measured results: analyst success rates and insider track-record accuracy.
Insider alerts
Summarized email alerts on the CEO, CFO and $1M+ buys that matter, sent as each filing is processed.
Congress & contracts
House and Senate trades and government contract awards, side by side with the insiders.
Bubbles & heat maps
The whole tape in one picture — insider bubbles, congress bubbles and sector flow.
Backtest figures are historical, gross of costs, and do not predict future results.

What is All-In Access?
One membership that unlocks everything on Insider Buying: full Insider Scores and Insider ROI, the ranked lists counted down to #1, top-analyst track records and upside ratings, congressional trades, government contracts, and real-time insider alerts.
Where does the data come from?
Insider activity is parsed first-hand from SEC Form 4 filings. Market data, analyst ratings and fundamentals come from licensed market-data providers. Congressional trades come from official House and Senate disclosures.
How fresh are the alerts?
Filings are ingested continuously throughout the trading day, and qualifying buys — CEO/CFO purchases and $1M+ open-market buys — hit the alerts feed as they are processed.
Can I cancel anytime?
Yes. Subscriptions are handled by Stripe and can be cancelled in one click from your account — you keep access until the end of the paid period.
Is this financial advice?
No. Insider Buying is a research platform. Every figure traces to a public filing or licensed data feed, and nothing on the site is a recommendation to buy or sell any security.
