Markin Volterra Fund LP's disclosed holdings carry a Herfindahl concentration index of 0.219 — mathematically equivalent to about 5 equally-sized positions, well below its 34 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 2.57), 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 7.7 percentage-point tilt) — a pattern consistent with a more contrarian, new-idea-driven approach.
Sector classification currently covers about 16% 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.
