Every insider buy and sell reported to the SEC on 2026-07-17, parsed from primary EDGAR filings into a clean dataset. Here are the moves that matter — and how the data is built.
TL;DR: On 2026-07-17, 29 individual directors & officers made open-market purchases of their own stock (~$5,004,059), against 394 open-market sales. Separately, 19 larger fund / 10%-owner buys (~$479,974,084) are kept apart so a bank's strategic stake doesn't masquerade as insider conviction.
Why individual insider buys are the signal
Insiders sell for a hundred reasons — taxes, diversification, a new house. They buy their own stock on the open market for essentially one: they think it's going up. That's why the number worth watching isn't "insider activity" in aggregate — it's individual directors and officers putting their own cash in, separated from institutional 10%-owner block trades.

How the dataset is built (and why it's not trivial)
It's not just "download the filings." The pipeline that produces this:
- Pulls the SEC EDGAR daily Form-4 index (free, keyless — with a compliant User-Agent).
- Parses each filing's
ownershipDocumentXML for issuer, insider, role, transaction code, shares, and price. - De-duplicates — a single trade by a fund group is filed through many affiliated entities (and repeated within a filing); on a busy day that's ~50% redundant rows. Collapsing them on the transaction identity is the difference between a real number and a 2× inflated one.
- Verifies deterministically — every row's value is checked against shares × price; codes validated; nothing AI-generated. Each row links back to its original SEC filing.
The result is a clean CSV / Excel table you can sort, filter (code = P for open-market buys), and drop into a screener or backtest — instead of writing an EDGAR parser yourself.
I run this every trading day and keep one cumulative, de-duplicated dataset updated — every Form 4 insider buy & sell, source-linked, in CSV + Excel. If you'd rather not maintain the scraper yourself, it's a membership here: https://unfairhq.gumroad.com/l/rtukz.
Your turn
Do you actually weight insider buying in your process — and if so, do you filter for clusters (several insiders at one company) or just the big single buys? Curious how others use this.
