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.
This company filed no 8-K forms in the last year. Foreign companies listed in the US (ADRs) report material events on forms 6-K and 20-F, and ETFs and funds do not file 8-Ks. If it is a foreign company listed in the US through ADRs (American Depositary Receipts), what trades are bank-issued certificates that represent shares from its home market. See its filings on EDGAR ↗
