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.
