Institutional ownership from SEC Form 13F filings. Investment managers with more than $100 million in U.S. equities must disclose their positions every quarter, within 45 days of quarter-end, so the holdings shown can lag the market by up to a quarter.
The Jun 30, 2026 filing window is
still open — showing the latest known positions. Funds that have not filed yet
carry their prior-quarter positions; a fund that filed without this stock counts
as sold out.
