How is hedge fund similarity measured?

Similarity is computed from each fund's top conviction holdings in their latest 13F filing. Funds are scored by the overlap of distinctive shared positions (the mega-caps that nearly every fund owns are excluded), so the ranking reflects genuinely shared strategy rather than common index exposure.

Similarity is derived from each fund’s latest 13F-HR filing with the SEC. Funds are ranked by the overlap of distinctive conviction holdings; near-universal mega-cap positions are excluded so the ranking reflects shared strategy, not common index exposure.
