The 10 13F filers with the most shares as of Jun 30, 2026, whatever their type (index firms usually come first). “Change”: shares added or cut versus the previous quarter, split-adjusted; “no data” = there is no comparable portfolio for the previous quarter (no filing, or a filing with its holdings under confidential treatment). “% of the company” only where shares outstanding are up to date. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. With a free account: the top 25, the largest buyers and the largest sellers.
Insiders (Form 4)
Open-market purchases, excluding 10b5-1 plans. Officers and directors only; joint filers of the same purchase count as one. 10% owners with no role are shown separately. 0 = nobody bought; “no data” = we do not have its Form 4 filings.
Above 5% (13D/13G)
This list may be incomplete: we hold 13D and 13G filings made since December 2024. A holder above 5% that has not filed anything since then is not shown here.
No recent filings.
All material events (8-K)
