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.
Some SEC filings for this period have not finished importing. Holder totals and changes may be incomplete; these filings remain queued for recovery.
The Sep 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. Each fund's Change is measured against its own
previous reported quarter, shown in the Reported column. Pick a
completed quarter in the Quarter selector below to put every
fund on one quarter and see the stock-wide activity breakdown.
