This small residual alpha of 0.1% for Berkshire, although measured, should not be the main evidence to claim that company size limits its future returns. If we had not already invested so much attention in this size restriction thesis, would we consider such a marginal figure as a decisive conclusion? It is crucial to ask, with fresh eyes, whether this figure is conditioned by specific factors rather than a universal truth. For example, regulatory changes on insurance float or a strategic shift could easily make this alpha disappear. It would then be the context, not size alone, that is decisive.
