Parthenon LLC's disclosed holdings carry a Herfindahl concentration index of 0.034 — mathematically equivalent to about 30 equally-sized positions, well below its 133 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes vary widely across the portfolio (a coefficient of variation of 1.87), with a handful of outsized bets alongside many smaller positions.
No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
