Morgens Waterfall Vintiadis & Co INC's disclosed holdings carry a Herfindahl concentration index of 0.084 — mathematically equivalent to about 12 equally-sized positions, close to its 14 actual disclosed holdings. Value is spread relatively evenly across the portfolio rather than concentrated in a handful of names.
Position sizes are fairly uniform across the portfolio (a coefficient of variation of 0.44), suggesting a disciplined, rules-based approach to how much capital goes into each idea.
Recent activity leans toward initiating meaningfully larger new positions than it adds to existing ones (a 4.7 percentage-point tilt) — a pattern consistent with a more contrarian, new-idea-driven approach.
