Sector conviction: 100
Diversification: 56
Sizing Uniformity: 82.72

Diameter Capital Partners LP's disclosed holdings carry a Herfindahl concentration index of 0.139 — mathematically equivalent to about 7 equally-sized positions, well below its 29 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 1.73), with a handful of outsized bets alongside many smaller positions.

Recent activity leans toward initiating meaningfully larger new positions than it adds to existing ones (a 4.2 percentage-point tilt) — a pattern consistent with a more contrarian, new-idea-driven approach.

Sector classification currently covers about 31% 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.
