Participation was mixed. 77 of 761 tracked companies finished the window net buyers of their own shares (10%); the rest were flat or net sellers.
TSM is the story: 30 separate insiders there filed open-market purchases in this window, which is a company-wide pattern rather than one executive acting alone. 29 other companies in this edition also drew more than one buyer.
No single name dominates the dollar total — the largest, GME, is 24% of the net open-market buying across the 10 names below.
More separate purchases were filed at ENR than at any other name here — 30 of them.
The individual purchases listed below were filed between Sep 15, 2026 and Sep 21, 2026, across 10 companies.
Companies with more than one insider buying
“Buyers” counts separate insiders who filed an open-market purchase (Form 4 code P) at that company in the window. The dollar figure is net of open-market sales by insiders at the same company, so it can be negative even where several people bought. The officer/director tag means at least one buyer filed a role other than 10% owner or an unspecified “insider”; untagged means no such role was filed, not that the buyers were anything in particular.
Largest net open-market buying this edition
Net value = open-market buys minus sells as disclosed on Form 4 (code P). Grants/options/withholding excluded.
Who filed, and when
Open-market purchases (Form 4 code P) only — grants, option exercises and tax withholding are excluded. Share counts are as disclosed in the filing.
