What is a Form 4 filing?

A Form 4 is the SEC document corporate insiders — officers, directors, and 10% owners — must file within 2 business days of buying or selling their own company's stock. It discloses the transaction date, share count, price, and the insider's post-trade holdings.

Are insiders buying or selling this week?

In the past 7 days, 456 insider buys and 1,668 insider sells were disclosed in SEC Form 4 filings tracked by HoldingsIntel.

How many insider trades does HoldingsIntel track?

150,392 Form 4 transactions, updated within 2 business days of SEC publication.

What do insider transaction codes P and S mean?

Code P is an open-market purchase and code S is an open-market sale — the two codes that reflect a genuine market decision. Other codes (A, M, G and similar) cover grants, awards, and option exercises, which are compensation events rather than market conviction.
