Boundless Plain Holdings Ltd's disclosed holdings carry a Herfindahl concentration index of 0.260 — mathematically equivalent to about 4 equally-sized positions, well below its 11 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 1.43), 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 25.1 percentage-point tilt) — a pattern consistent with a more contrarian, new-idea-driven approach.
