Blue Grotto Capital, LLC's disclosed holdings carry a Herfindahl concentration index of 0.065 — mathematically equivalent to about 15 equally-sized positions, close to its 21 actual disclosed holdings. Value is spread relatively evenly across the portfolio rather than concentrated in a handful of names.

No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
