About Insider Tracker
What this site shows, where the data comes from, and what it cannot tell you.
What it shows
Company insiders (officers, directors, owners of more than 10%) must report their trades to the SEC on Form 4 within two business days. This site reads those forms, keeps the open-market purchases and sales, and groups purchases by three or more distinct insiders of one company into buying clusters. Each cluster gets a score from 0 to 100 that is split into its parts on the cluster page.
Where the data comes from
- Insider trades, company names, share counts: SEC EDGAR, the regulator's public filing system.
- Daily prices: the public DoltHub dataset
post-no-preference/stocks(CC BY-SA 4.0), with gaps and over-the-counter symbols filled from Massive (formerly Polygon.io). Prices are end-of-day. - Sector and industry: the SEC's SIC code of each company. It is approximate and can differ from the classification you know.
- Market pages: Yahoo Finance, fetched by your own browser through an optional extension. This server never receives that data.
How fresh it is
The pipeline is set to look for new filings every 15 minutes from 07:00 to 22:45 New York time, Monday to Friday, and to complete each day and refresh end-of-day prices once a day. This copy was last updated 2026-10-13 14:15 UTC and contains filings accepted up to 2026-10-13 10:13 ET.
What it cannot tell you
The score describes the buying: how many insiders, how senior, how much. It is not a forecast. Missing inputs are shown as missing and count as neutral. This is a research tool, not investment advice, and nothing here is a recommendation to buy or sell a security.
