Net flow in the quarter: −$17.1M (−1.7 M shares) · bought $394K and sold $17.5MShares concentrated managers added minus those they cut, valued at the 13F quarter-end implied price, not each trade's price. It is a different measure from the change in managers: the two can have opposite signs.

The set of concentrated managers changed between quarters: with the set as it was then, 6 held it last quarter (the chart point); with today's set, 7 (the base for the change).

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.

Shares reported by the 83 13F filers as of Jun 30, 2026, divided by the shares outstanding on the cover of the company's latest report (Dec 31, 2025). It is not all institutional ownership: only managers above $100M file a 13F, and it excludes short positions. Entities of the same group file separately and some 13F filings include other managers: there may be double counting. We only publish it where the figure is credible: not for ADRs, companies with more than one share class or stale shares-outstanding data.

Above 5% over time (13D/13G)

Each holder with its filings in order. History since December 2024.

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.
