In the last seven days, insiders reported 403 purchases (Form 4 code P) at 121 companies. 175 different insiders bought $467.77M of stock between them. That is down 29% on the $657.00M bought the week before.
The largest single purchase came from BERKSHIRE HATHAWAY INC (10% owner), who bought $52.12M of LENNAR CORP /NEW/ (LEN).
Two or more insiders bought the same stock at 5 companies, which is what we call cluster buying: ADRX (5 insiders), GME (2 insiders), PORT (2 insiders), BPRE (2 insiders), PAM (2 insiders). The cluster page has the 14-day list.
These figures count SEC Form 4 purchases (transaction code P) filed between 2026-09-28 and 2026-10-04. Code P covers open-market and private purchases. Grants, option exercises and shares withheld for tax are left out, because they are pay rather than a decision to buy. Cite the week number and the dates.
