Largest options & derivatives disclosed

13F filers disclose option positions at the market value of the underlying the contracts reference, not the premium paid. A put is a bearish bet (it gains if the stock falls); a call is bullish. “Underlying shares” is the share count the contracts control, not a share holding. These legs are excluded from the equity book, weighting, concentration and sector figures above.

Fund
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.
