Shelter Mutual Insurance Co's disclosed holdings carry a Herfindahl concentration index of 0.029 — mathematically equivalent to about 35 equally-sized positions, close to its 58 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 0.82), 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 2.9 percentage-point tilt) — a pattern consistent with a momentum-following approach.
Sector classification currently covers about 58% 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.
