What it does
Pulls every SEC Form 4 filing across US-listed companies — CEOs, CFOs, directors, and 10% owners buying or selling their own stock — and returns clean records with shares, price, total value, post-transaction ownership, and a cluster-buy flag when multiple officers transact simultaneously. Filter by ticker, date range, transaction type, insider role, and minimum dollar value.
Who it's for
Hedge funds and quants modeling insider flow, retail smart-money followers, and compliance teams auditing Section 16 activity — a Bloomberg insider-flow alternative without the $24K/year terminal.

- Detect cluster buying by multiple officers, a pattern shown to outperform the S&P 500 by 6–12% over the following year.
- Audit Section 16 filing activity across a coverage list for compliance review.

FAQ
How quickly do Form 4 filings appear?
Insiders must file within 2 business days of a transaction, and filings are public immediately — the actor surfaces them as the SEC publishes.
What is cluster-buy detection?
When multiple officers or directors of the same company buy within a short window, the actor flags it — cluster buys are the most studied and strongest insider-trading signal.
Is this legal insider-trading data?
Yes — Form 4 is the SEC's mandatory public disclosure of insider transactions under Section 16(a). This is the legal, disclosed kind that funds pay terminals to monitor.
