Robertson Opportunity Capital, LLC — Inside Their 13F Portfolio

Robertson Opportunity Capital, LLC's disclosed holdings carry a Herfindahl concentration index of 0.054 — mathematically equivalent to about 18 equally-sized positions, close to its 30 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 0.81), suggesting a disciplined, rules-based approach to how much capital goes into each idea.
