About these leaderboards
13F boards are computed from the latest non-superseded quarterly filing of every tracked fund; insider boards from open-market Form 4 purchases over a rolling window. Pick any quarter or window on a board to see that point-in-time ranking. The manager board separates disclosed focus/activity from any gated price-derived track record, so "conviction" never masquerades as performance. All data is public domain, sourced to SEC EDGAR, and available programmatically via the Arkolith API & MCP server.
