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.
