The idea that Berkshire Hathaway's stock market capitalization growth to $1.08 trillion inherently limits its informational advantages and flexibility in capital allocation is a charitable thesis that highlights a real challenge of large-scale management.
However, a careful reading of their strategy reveals that the insurance float, for example, is not simply a constraint but a unique advantage that adapts to size.
The strength of this argument is that size can complicate investment searches, but Berkshire has historically turned this obstacle into an opportunity by targeting massive acquisitions or entire markets, thus shifting the very nature of its advantages.
