What is a Form 4?
Company officers, directors and owners of more than 10% of a company’s shares must report their trades in its stock to the SEC on Form 4, within 2 business days of the trade. Each report lists what they traded, how many shares, the price and what they own afterwards.
How this list is counted
Each row adds up one insider’s open-market purchases (transaction code P) of one stock, from the Form 4s filed in the last seven days, and the rows are ranked by value. Stock awards, option exercises, gifts and amended reports are left out, and a purchase that related firms each reported is shown once. The price is the average the insider paid across those purchases.
Questions people ask about insider buying.
What was the biggest insider purchase this week?
NIPPON LIFE INSURANCE CO, 10% owner at Corebridge (CRBG), reported buying 919,758 shares at an average of $34.90, about $32.1M, in 4 Form 4s, the latest filed Oct 22, 2026.
What is a Form 4?
Form 4 is the report a company’s officers, directors and owners of more than 10% of its shares file with the SEC when they buy or sell the company’s stock. It is due within 2 business days of the trade.
What counts as an open-market insider buy?
A purchase reported with transaction code P: the insider bought shares at a price they paid, on the market or in a private sale. Stock awards, option exercises, gifts and shares withheld for taxes use other codes and are not counted here.
How quickly do insiders have to report a trade?
Within 2 business days of the trade, so this week’s Form 4s mostly cover trades made in the last week or so. The table shows the day each report was made public.
Is insider buying a signal?
It is one piece of information, not a recommendation. Insiders know their company well, which is why many investors follow these reports, but they buy for many reasons and a purchase says nothing certain about where the stock goes next. Instaport shows these filings as information, not advice.
Can I get an alert when an insider buys a stock I own?
Yes. Instaport alerts you when company insiders, top funds and members of Congress buy or sell a stock you own. It starts with a free account.
