BRK-B — Berkshire Hathaway Inc.

The market's mood on Berkshire as of 2026-09-13 is politely indifferent rather than bearish. Q2 2026 (reported August 8) beat handily - operating earnings of $12.98B, up 16.3% YoY, and operating EPS of ~$6.02 vs ~$5.13 consensus - and management did two things bulls have waited years for: it repurchased ~$4.5B of stock in Q2 alone (~$4.8B in H1) and was a net buyer of public equities for the first time in 14-15 quarters, cutting cash/T-bills from a ~$397B peak to ~$366B, plus closing the $8.5B Taylor Morrison homebuilder deal on July 24, 2026. Yet the sell-side still says 'Hold' (4 Buy, 6 Hold, 0 Sell) and the stock is flat over one month and lagging a momentum-driven index, which is the classic Berkshire pattern during tech-led bull runs. Analyst targets ($594.50 recent average, $604 high/consensus, but only two price-target contributors) sit 16-18% above the 2026-09-13 price, so the market is splitting the difference between 'fortress, buybacks, optionality' and '1.47x book, ~23x operating earnings.'

The trend inflected upward over the last three quarters after a flat-to-soft 2024-2025 stretch. Revenue YoY went from -1.2% (Q2 2025) and -0.7% (Q4 2025) to +2.1% (Q3 2025), +4.4% (Q1 2026) and then +10.0% in Q2 2026 ($101.8B vs $92.5B) - the strongest print in the three-year window. Operating income confirms it: $17.49B in Q2 2026 vs $15.58B a year ago (+12.2%), and $15.37B in Q1 2026 vs $12.71B (+20.9%). Operating margin was 17.18% in Q2 2026 versus 16.85% in Q2 2025 (+33bps) - modest expansion, not a step-change, and roughly in line with the 17.55% posted in Q3 2025. Free cash flow is the cleanest improvement: TTM FCF through Q2 2026 is ~$24.2B versus ~$8.2B a year earlier (+194%), because the two negative-FCF quarters (Q3 2024 -$2.90B, Q4 2024 -$0.73B) have rolled out of the window. Important caveat: GAAP net income is nearly useless as a trend signal here - it swings from -$12.77B (Q3 2023) to +$37.57B (Q4 2023) to +$30.80B (Q3 2025) on mark-to-market equity gains. Judge this company on operating earnings and book value, both of which are improving steadily.

Not cheap, and modestly rich against its own history. As of 2026-09-13 the headline TTM P/E was 12.84x on $39.75 of TTM GAAP EPS - but that EPS is inflated by unrealized investment gains, and the honest number is the ~23.0x forward multiple on the $22.18 next-FY operating EPS estimate. The 5-year average P/E of 10.69x (4 years of data used) and 5-year average P/S of 2.48 vs. current 2.864 both say the stock sits at a premium to its recent norms, which is why the deterministic model labels it 'Rich vs. its own history.' P/B of 1.466x is mid-to-upper range versus the ~1.2-1.6x band Berkshire has occupied for a decade. PEG of 0.354 looks spectacular but is an artifact of GAAP earnings volatility and should be ignored. The offsetting point: on the ex-cash math the brief cites, stripping ~$366B of cash/T-bills from a $1.10T market cap leaves ~$735B for ~$48B of operating earnings, or ~15x - genuinely reasonable for a 0.61-beta fortress. Net: fairly valued at best on headline multiples, arguably 5-10% cheap only if you give full credit to the cash pile.

At $510.37 on 2026-09-13 you are paying ~23x forward operating earnings for a business compounding operating earnings in the high single digits. That means the stock is not discounting a growth surprise - it is discounting the balance sheet. The upside case is not an earnings beat; it is (a) deployment of the ~$366B liquidity into something accretive, (b) a market dislocation that lets Berkshire buy assets cheap, or (c) continued multiple creep as investors pay up for a 0.61-beta defensive in a fragile tape. The downside case is equally mechanical: if operating earnings grow ~7% and the multiple compresses back toward 20x, you get roughly flat returns. Watch two things quarterly: the pace of buybacks (management's own tell on intrinsic value - they bought at roughly 1.40-1.50x book in Q2 2026) and the change in cash/T-bill balances. Rising cash in a rising market is a warning; falling cash funded by acquisitions or equities is the bull case showing up in the numbers. With $4.8B of H1 2026 repurchases and the first net equity-buying quarter in 14-15 quarters, the tape currently supports the bull read - but neither is yet large enough to move a $1.1T market cap.

As of 2026-09-13, BRK-B was in a mild, orderly uptrend, not an overbought one. RSI(14) was 57.47 - above neutral, comfortably below 70. The price sat 1.31% above its 20-day SMA, 1.29% above its 50-day SMA and 3.63% above its 200-day SMA, so all three trend measures are positively stacked but the extensions are small, which is typical for a low-beta name. Performance was +0.86% over one week, +0.07% over one month, +4.32% over three months and +4.15% over six months - a slow grind, with the last month essentially flat and the 3-month gain front-loaded. The 52-week range of $464.01-$537.74 puts the stock about 5% below the high and about 10% above the low, i.e., in the upper-middle of a well-defined range. Practical read: no urgency to chase, and no technical reason to avoid. The 200-day SMA sits roughly 3.6% below the market price, so a pullback into the $480-495 zone would be the higher-conviction entry; a decisive break above $537.74 would signal the market is finally willing to pay up for the defensive/optionality trade.

• Short-term interest rates and T-bill yields: Berkshire's ~$366B liquidity book is directly levered to the Fed - elevated rates generate enormous risk-free interest income today, while a cutting cycle would trim that income but simultaneously lift the mark-to-market value of the equity portfolio and book value.
• Equity market level and concentration: because the investment portfolio is marked to market through GAAP earnings, a broad drawdown (especially in mega-cap tech) hits reported net income and book value immediately, even though it is also the environment in which Berkshire's cash pile becomes most valuable.
• US housing and consumer cyclicality: the $8.5B Taylor Morrison acquisition completed July 24, 2026 plus Clayton Homes and building-products exposure make Berkshire increasingly levered to mortgage rates and household formation, for better or worse.
• Freight, industrial demand and tariffs: BNSF volumes and pricing track industrial production and trade flows, so tariff-driven shifts in goods movement are a direct earnings variable for the largest non-insurance subsidiary.
• Insurance cycle and catastrophe load: GEICO auto margins and reinsurance pricing are cyclical, and Berkshire Hathaway Energy carries meaningful wildfire/liability tail risk - a single large catastrophe quarter can swamp an otherwise good operating print.

• Q3 2026 earnings, expected early November 2026 - the next real read on Greg Abel's pace of cash deployment, GEICO underwriting, BNSF volumes, and whether the net-buyer posture on equities continues.
• Continued share repurchases - roughly $4.8B was executed in H1 2026 ($4.5B+ in Q2 alone); a sustained multi-billion-per-quarter pace is management's clearest public statement that the stock trades below intrinsic value.
• 13F and portfolio disclosures - the expanded Delta Air Lines stake and a newly disclosed Alphabet position (initiated under Buffett) show a willingness to put money to work; further large additions would validate the 'cash is a call option' thesis.
• Rate cuts or a market dislocation - either could finally convert the ~$366B cash/T-bill pile from an earnings drag into an acquisition engine, which is the single largest source of upside optionality.
• Integration of Taylor Morrison ($8.5B, closed July 24, 2026) into an eventual housing-cycle recovery, which would mark a shift from pure financial-asset accumulation toward hard-asset, cash-generating operating earnings.

• Valuation risk: at 1.47x book and roughly 23x forward operating earnings, the stock has no real margin of safety - the bull case depends on either multiple persistence or a genuinely accretive use of the $366B cash pile, and the deterministic model's own reading is 'Rich vs. its own history.'
• Key-person and transition risk: Greg Abel is now running capital allocation, and while the buyback and equity-purchase activity in Q2 2026 is encouraging, his judgment is unproven across a full cycle relative to the Buffett track record that produced the valuation premium he is now inheriting.
• Earnings-quality optics: the accruals ratio of +1.14% as of 2026-06-30 (net income exceeding operating cash flow) reflects mark-to-market equity gains flowing through GAAP income - structurally unavoidable here, but it means reported earnings will keep diverging violently from cash generation and can mask genuine operating issues.
• Mark-to-market / concentration risk in the equity portfolio: reported net income and book value swing on the mark (a single quarter printed +$30.8B in Q3 2025), so a tech-led drawdown would dent book value and the multiple at the same time.
• Scale and cash drag: at a $1.10T market cap with $365B+ in short-duration instruments, a falling-rate environment shrinks interest income meaningfully while the sheer size of the company makes any acquisition big enough to matter increasingly hard to find; ROE of 9.3% and ROIC of 4.1% already show the drag.

Berkshire is a genuinely high-quality, low-beta compounder whose operating momentum re-accelerated sharply in Q2 2026 - revenue +10.0% YoY, operating income +12.2% YoY, TTM free cash flow up roughly 194% YoY - and management is finally signaling conviction with ~$4.8B of buybacks in H1 2026 and its first net equity-buying quarter in 14-15 quarters. The problem is the price: 1.47x book and ~23x forward operating earnings is the high end of Berkshire's own historical range, and the GAAP P/E of 12.84x that makes it look cheap is distorted by investment gains. You are buying a superb balance sheet and a $366B option on a market dislocation at a full-but-not-crazy price; I would own it as a defensive core holding and add on pullbacks toward $480-495, not chase it at $510. Expected return from here is modest - high single digits - not the 16-18% implied by the $594-604 sell-side targets.

Two-metric blend, averaged 50/50. (1) Earnings leg: forward operating EPS of $22.18 (the next-FY consensus estimate, which reconciles with ~$48B of normalized after-tax operating earnings on ~2.157B B-share equivalents) at 22.5x - the midpoint of Berkshire's recent 18-25x operating-earnings range, with a small premium for the 0.61 beta and $366B liquidity offset by a 9.3% ROE - giving $499. (2) Book leg: Q2 2026 book value of $347.8 per B-share ($750.2B / 2.157B shares) grown ~10% to a 12-month-forward $382, at 1.50x P/B, a multiple supported by management's own revealed willingness to repurchase stock at roughly 1.40-1.50x book in Q2 2026, giving $574. Average = $536, about 5% above the 2026-09-13 price of $510.37 and well below the two-analyst $594.50-604 consensus, which I view as too generous relative to Berkshire's historical multiple range.
