Momentum/Contrarian: 94.69
Sector conviction: 44.38
Diversification: 100
Sizing Uniformity: 81.97

Klingenstein Fields & Co LP's disclosed holdings carry a Herfindahl concentration index of 0.023 — mathematically equivalent to about 44 equally-sized positions, well below its 255 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 1.80), 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.
