The idea that Berkshire Hathaway's growth was not hindered by its size is a past observation that ignores the current market constraints. The notion that size does not affect sustained alpha is a generalization that does not account for structural specifics. Berkshire has been able to bypass certain limits by acquiring entire companies, which is a different option from simply allocating capital to listed securities. For example, a Swiss wealth manager seeking to generate alpha often turns to niche investments or private participations for significant returns, as liquid markets are too efficient for large allocations. Such posture is controllable and more relevant for alpha generation today.
