Insider buying

When an officer or director buys their own company’s stock on the open market, they file a Form 4 within two business days. This is those filings: 120 purchases worth $433.1M, newest first. Grants, option exercises and tax withholding are excluded, which is most of what Form 4 actually reports.

About 93% of Form 4 transactions are compensation mechanics: options exercised on a vesting schedule, shares surrendered to pay the tax on an award, the award itself. They fire on a calendar nobody chose this quarter. Only transaction code P, an open-market purchase at a price the buyer did not set, reflects a decision, and it is about 5% of the feed.

Where several insiders bought at once

Companies where three or more different officers or directors bought inside 90 days. Counted per person, not per filing, so one executive buying repeatedly does not become a crowd.

What this covers, and what it is worth

13,287 Form 4 filings across 52 days, 26 Jul 2026 to 15 Sept 2026, of which 1,362 carry an open-market purchase. Filings arrive up to two business days after the trade, so the newest rows here are already a few days behind the decision they report.

Insider buying is a well-documented signal and has been studied since the 1970s, which is the main thing to know before reading too much into it: whatever edge remains is modest, slow, and concentrated in small companies where it is hardest to act on. A single purchase is also a fact about one person’s finances before it is a fact about the business.

Filings are US-listed issuers only, and about 13% of purchases are at companies with no page here (OTC, blank-check and freshly listed issuers the rest of the site does not cover), so those rows carry a ticker but no link. Insider transactions from SEC Form 4 filings (public domain). Nothing on this page is investment advice.
