Codex Capital Asset Management L.L.C.'s disclosed holdings carry a Herfindahl concentration index of 0.060 — mathematically equivalent to about 17 equally-sized positions, well below its 31 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes are fairly uniform across the portfolio (a coefficient of variation of 0.94), suggesting a disciplined, rules-based approach to how much capital goes into each idea.
Recent activity leans toward adding more aggressively to already-large existing positions than to newly initiated ones (a 2.7 percentage-point tilt) — a pattern consistent with a momentum-following approach.
