Residual alpha of 0.1% for Berkshire is certainly a statistical curiosity, but historically, such residual alpha claims for entities of this scale should be approached with healthy skepticism. The market playbook has long taught us that the ability to generate significant alpha diminishes as assets under management increase, because large-scale investment opportunities are rare. Considering this small figure as decisive evidence against size restrictions ignores precedents where sovereign funds managing hundreds of billions struggle to outperform their indices after fees. An alpha of this magnitude could easily be drowned in methodological noise or market fluctuations, as seen with the ephemeral quants' alphas in the 90s, which evaporated over time.
