Position sizes are fairly uniform across the portfolio (a coefficient of variation of 0.70), 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.
