Wasserstein Management, L.P. 13F Filings Tracker (Q1 2026): Interactive Charts, AI & API

Wasserstein Management, L.P.'s disclosed holdings carry a Herfindahl concentration index of 0.765 — mathematically equivalent to about 1 equally-sized positions, well below its 4 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 1.66), 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 4.3 percentage-point tilt) — a pattern consistent with a more contrarian, new-idea-driven approach.

Sector classification currently covers about 8% 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.
