How could the growth of Berkshire Hathaway's market capitalization itself potentially degrade informational advantages and capital allocation flexibility?
This ignores the role of discipline in company management.
Holding strategic cash reserves by Berkshire, even at a trillion dollars, is not a constraint but evidence of intentional management, as demonstrated by their opportunistic acquisitions during periods of market turbulence.
Size is not the determining factor, but the underlying deployment strategy.
For example, their patience in waiting for undervalued investment opportunities, rather than rushing, maintains an unexpected flexibility for a company of this size.
