Aristotle Capital Boston, LLC's disclosed holdings carry a Herfindahl concentration index of 0.012 — mathematically equivalent to about 82 equally-sized positions, close to its 122 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 0.70), suggesting a disciplined, rules-based approach to how much capital goes into each idea.
No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
Sector classification currently covers about 63% 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.
