Barbara Oil Co.'s disclosed holdings carry a Herfindahl concentration index of 0.031 — mathematically equivalent to about 32 equally-sized positions, well below its 73 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes are fairly uniform across the portfolio (a coefficient of variation of 1.13), suggesting a disciplined, rules-based approach to how much capital goes into each idea.
No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
