About insider trading data

What is a Form 4 / insider transaction?

Corporate insiders — officers, directors, and 10%+ shareholders — must report their trades in the company’s stock to the SEC on Form 4 within two business days. These filings reveal what people closest to a company are buying and selling.

Which transactions are shown here?

We surface open-market purchases (transaction code P) and sales (code S) — the trades that reflect an actual buy/sell decision. Routine, non-discretionary events like option grants, vesting, tax-withholding and gifts are filtered out as noise, and we focus on the most recent, most meaningful trades by dollar value.

Is insider buying or selling a reliable signal?

Insiders trade for many reasons (taxes, diversification, options vesting), so selling is often noise. Clustered, open-market buying by multiple insiders is the pattern most commonly watched. This data is informational only, not investment advice.

Where does the data come from, and how fresh is it?

Corporate trades are sourced directly from SEC EDGAR Form 4 filings and refreshed daily. Each filing’s disclosure delay (filing date minus trade date) is shown, and a delay of a week or more is flagged in red as a late filing.

What is the STOCK Act, and where are congressional trades?

The STOCK Act (2012) requires members of the U.S. Congress to disclose their securities trades, generally within 45 days. Congressional trade tracking is coming soon; for now this page covers SEC Form 4 corporate insider activity.
