New buyers

No tracked exits this quarter.

Full-market context: across ALL 13F filers (SEC structured data, Q1 2026): 2,223 holders, 597.68M shares, $78.12B reported. This is a different, older period than the tracked-universe figures above and the two are never mixed.

Frequently co-owned

What else this security's tracked holders most often hold — shared-ownership counts, not fundamental relationships.

Provenance: Ownership from parsed 13F common-stock positions (tracked universe, comparable sets for changes); insider rows from Forms 3/4/5; stakes from Schedules 13D/13G; every filing links to its original on SEC EDGAR. Reporting period: Q2 2024 · Methodology · Get this via the API
