In the last seven days, insiders reported 321 purchases (Form 4 code P) at 128 companies. 145 different insiders bought $657.00M of stock between them. That is up 123% on the $295.26M bought the week before.
The largest single purchase came from BERKSHIRE HATHAWAY INC (10% owner), who bought $93.08M of LENNAR CORP /NEW/ (LEN).
Two or more insiders bought the same stock at 5 companies, which is what we call cluster buying: ETRA (2 insiders), GRAB (2 insiders), GME (2 insiders), NYAX (2 insiders), HHH (2 insiders). The cluster page has the 14-day list.
These figures count SEC Form 4 purchases (transaction code P) filed between 2026-09-21 and 2026-09-27. 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.
