How to read this page

This page summarizes how large institutional investment managers report holding this security in their quarterly SEC Form 13F-HR filings. A 13F filing is a mandatory disclosure that any manager with at least $100 million in qualifying US-listed equity assets must submit to the Securities and Exchange Commission within 45 days of the end of each calendar quarter. The figures here therefore describe long equity positions as of a specific reporting quarter, not live market quotes, and not a manager's complete book. 13F disclosures deliberately exclude short positions, cash, most derivatives, non-US listings, and small holdings, so the institutional ownership shown is a floor rather than a full picture. "Holders" counts the distinct managers reporting a position; "reported value" sums the market value those managers disclosed; and "top-5 concentration" measures how much of that reported value sits with the five largest holders. Use these numbers to understand institutional interest and how it shifts quarter over quarter, never as a recommendation to buy or sell. Every figure is rendered directly from the underlying filings and can be verified against the original documents on SEC EDGAR.
