Long book

Aggregated from SEC Form 13F filings (institutional long equity positions, reported quarterly, up to 45 days after quarter-end). Holdings are public domain, sourced to SEC EDGAR. The book totals, weighting, concentration and sectors are long equity only; disclosed put/call options are listed separately and excluded from those figures. Price-derived performance is withheld until the price-source policy and freshness gate are green. Every panel is one call to the Arkolith API & MCP server.
