Custos Family Office, LLC's disclosed holdings carry a Herfindahl concentration index of 0.071 — mathematically equivalent to about 14 equally-sized positions, well below its 71 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes vary widely across the portfolio (a coefficient of variation of 1.95), with a handful of outsized bets alongside many smaller positions.
Recent activity leans toward adding more aggressively to already-large existing positions than to newly initiated ones (a 2.2 percentage-point tilt) — a pattern consistent with a momentum-following approach.
Sector classification currently covers about 17% of this portfolio's disclosed value; the remainder includes holdings (e.g. unmapped tickers, options, or other security types) not yet covered by our sector mapping.
