Hauser Brothers GmbH SEC 13F Disclosure Analysis

Hauser Brothers GmbH's disclosed holdings carry a Herfindahl concentration index of 0.340 — mathematically equivalent to about 3 equally-sized positions, close to its 4 actual disclosed holdings. Value is spread relatively evenly across the portfolio rather than concentrated in a handful of names.

Position sizes are fairly uniform across the portfolio (a coefficient of variation of 0.69), 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 23.7 percentage-point tilt) — a pattern consistent with a momentum-following approach.
