Track Insider Trades with AI
Corporate officers, directors, and 10%+ shareholders must file Form 4 with the SEC within two business days of buying or selling company stock. These legal disclosures reveal when executives put their own money on the line — or quietly exit a position before bad news. Pineify Finance Agent lets you ask plain-English questions about any ticker's insider activity and surfaces cluster signals, open-market purchases, and unusual transaction patterns across thousands of filings.
Form 4 Filings, Not Illegal Activity
When people hear "insider trading" they often think of criminal cases involving stolen tips. This page covers something entirely different: the legal disclosure system regulated by the SEC. Under Section 16 of the Securities Exchange Act, corporate insiders — executives, board members, and large shareholders — must report every stock transaction on a Form 4 within 48 hours. These filings are public record, updated daily on the SEC EDGAR database. Tracking them is legal, transparent, and widely used by institutional investors. Pineify aggregates these Form 4 disclosures, highlights open-market purchases (which carry the most signal since insiders pay full market price), and flags cluster buying — when multiple insiders buy within the same 30-day window.
How It Works
- 1
Ask a question in plain English — for example, "Show me recent insider buys for $META" or "Which semiconductor CEOs bought stock this quarter?"
- 2
Pineify queries the SEC EDGAR Form 4 database and filters for the transaction types, date ranges, and dollar thresholds most relevant to your question.
- 3
Results include the insider's name and title, transaction type (open-market buy, option exercise, gift, etc.), share count, price paid, and a direct link to the SEC filing.
- 4
For cluster signals, Pineify highlights windows where three or more insiders from the same company filed purchase transactions within 30 days of each other.
- 5
You can follow up in the same conversation: "Now show me their revenue trend for the same period" or "Compare this to the previous quarter's insider activity."
