Chubb Limited (CB)
Financieras / Seguros
A global property and casualty insurer, with $55.2bn of net premiums earned — a disciplined underwriting machine (82.7% combined ratio in the trailing twelve months to Jun-30-2026, 83.8% in the quarter) plus a $175.4bn float that yields increasingly more with rates high, compounded by Evan Greenberg. Trades at ~12× core operating income and at around 2× book value. Base case 5y ~$480 (+8%/year): Fairly valued — a superb compounder at a full but reasonable price; the soft property market, already pulling down North America commercial premium, is the headwind to watch.
Moat Compounder estimates the intrinsic value of Chubb Limited (CB) at $480 per share on a five-year horizon. With the stock at $345.06 at 2026-10-12 close, the expected total return is 8.1% per year: fairly valued. The analysis draws on 10-K FY2025 and 8-K dated Jul-21-2026 (Q2 2026 press release and financial supplement). Analysis dated 2026-07-28.

The essentials
- A global property and casualty insurer —$55.2bn of net premiums earned in the trailing twelve months to Jun-30-2026 and $281.3bn of assets— that underwrites with discipline: 82.7% combined ratio in that trailing period and 85.7% in FY2025 — below 100% there is a technical underwriting profit, before investment income, and Chubb has run in the low-to-mid 80s for years. Globally diversified by the quarter's written premium: North America Commercial 38%, Overseas General 27%, Life 13%, and the rest (high-net-worth personal, agricultural, and reinsurance) 22%. Berkshire Hathaway is the largest disclosed shareholder in the proxy, at 8.07%.
- The float —$175.4bn of invested assets at Jun-30-2026, which management describes as its invested assets "up 9% over the last twelve months"— is the superpower: Chubb invests premiums collected before paying claims and keeps the yield ($6.8bn of net investment income in the trailing twelve months; $1.88bn adjusted in the quarter alone, a record, +11.4%). Combined with profitable underwriting, book value per share rose 12.3% year-over-year to $195.45 and tangible book value 17.1% to $131.93, with 33 consecutive years of dividend increases. Annualized return on equity of core operating income was 14.3% in the first half, and on tangible equity, 20.9%.
- ⚠️ The pricing cycle turned soft, and it shows in the company's own premium: property and casualty written premium grew just 3.0% in the quarter —6.3% excluding major accounts and E&S property— with North America Commercial at −2.3% and the major accounts and specialty business at −9.0% on property underwriting decisions. Management describes "excessively soft" conditions in global property, extending into parts of casualty and financial lines. At ~$345 it trades at around 2× book value; base case 5y ~$480 → total return +8%/year: Fairly valued.
Intrinsic value — two valuation methods
Total return at 5 years: 8.1%/year = 6.8% appreciation + 1.2% dividend. The target price ($480) is ex-dividend; the $24 in dividends collected over 5 years are added separately.
By both methods, the value today (DCF $740 · Multiples $406) exceeds the market price ($345).
Pillars of the analysis
The verdict — today vs 5 years
Today — fairly valued: at $345 trades ~15.1% below its value discounted to today (~$406); the discount is positive but does not reach the margin of safety we require (≥38%).
At 5 years — En valor: the target price ($480) plus dividends yield between the 4% floor and the 10% average return — a reasonable return, though without the margin of a great investment.
The bridge: the return at 5 years exceeds the risk-free rate (4.5%) — but the discount does not reach the required margin of safety (≥38%). To require a 15% annual return, it would need to be bought at ~$255.
Thesis
The business
Chubb is a global property and casualty insurer, with $55.2bn of net premiums earned — a disciplined underwriting machine (82.7% combined ratio in the trailing twelve months to Jun-30-2026, 85.7% in FY2025) plus a $175.4bn float that yields increasingly more with rates high. Globally diversified: 54 countries, commercial plus personal plus life in Asia. Book value per share rose 12.3% year-over-year and tangible book value 17.1%, plus a 33-year dividend aristocrat streak. The moat is underwriting discipline, scale, and balance sheet strength, but it is an execution moat: it depends on Evan Greenberg's culture, 71 years old with no named successor. Berkshire Hathaway is the largest disclosed shareholder in the proxy.
The valuation
An insurer is valued on equity —a multiple on earnings plus price against book value, with return on equity as the profitability measure— never on enterprise value: the float is low-cost funding of its own, not capital structure. The metric is core operating income, not GAAP net income, because the latter carries realized portfolio gains that are not underwriting economics. At ~$345, Chubb trades at ~12× that income and at around 2× book value.
The base year is not the raw trailing twelve months: core operating income of $11,516 million is normalized to $10,768 million because the period's catastrophe load, 3.4 points of earned premium, came in well below the three-year range the annual report publishes (4.5%, 5.5%, and 6.3%), and that difference does not repeat. On that basis, the base scenario projects earnings growing 4.6% in the first year and converging to 3% by year five —premium plus float income, moderated by the soft property market—, a buyback that reduces shares 2.5% a year, and an exit multiple of 12.5 times, the center of the method's band for this type of business. That gives ~$480/share; adding the dividend, the total return is +8%/year.
The margin of safety
It trades close to intrinsic value, far from the required margin of safety. At ~$345, Chubb is a superb compounder at a full but reasonable price. The verdict is Fairly valued: the quality is beyond question —a combined ratio sustained in the low-to-mid 80s, a growing float, 33 years of dividends, Berkshire as the largest disclosed shareholder in the proxy— and the price is not expensive on earnings terms, but against book value there is no discount, and the pricing cycle that turned soft is a headwind to the underwriting margin. The total return (+8%/year) is decent but not exceptional: book value compounding plus the dividend, with little room for re-rating from an already full multiple. The adverse scenario —a prolonged soft cycle plus a mega-catastrophe year plus multiple compression— has limited downside, because insurance is recurring and recession-resilient; the favorable one —prices re-harden, the float yields more, and the multiple expands— is a clear upside. The value discipline says this is a great business at a fair price: better bought at a cycle trough or a catastrophe scare than near highs.
What to watch
Three things. The property and casualty pricing cycle, the central disconfirmer: written premium grew just 3.0% in the quarter, with North America Commercial at −2.3% and major accounts and specialty at −9.0% on property underwriting decisions; if the softening persists and reaches casualty, the combined ratio rises and the margin compresses. Evan Greenberg's succession: at 71 with no named successor, the underwriting-discipline culture is his legacy and the transition is the biggest structural question. And the catastrophe load plus float income: the trailing twelve months ran at 3.4 points of catastrophes against a three-year range of 4.5 to 6.3 points, so the reported result is helped by a benign year —the model normalizes it— while the $175.4bn float keeps yielding more with each portfolio renewal. At this price, the best entry comes with a cycle trough or a catastrophe scare.

Valuation by multiples
The multiple is applied to the metric per share (EPS / Core FFO): that metric already reflects the evolution of the share count (buybacks or issuance), so the share count does not enter as a separate step. The implied equity (~$185.2 bn) is the metric carried to the equivalent of today's share count — the detail is in the piece's (i).
Discounted cash flow to present value (DCF)
Core operating income for the trailing twelve months to Jun-30-2026, normalized to a mid-cycle catastrophe load (an insurer has no depreciation or working capital to subtract: core operating income is the owner's earnings) as the base. Move the assumptions: the value recalculates live. The verdict remains anchored by multiples; the DCF contrasts it at present value.
Risk does not inflate the rate: protection is required separately, as a margin of safety over the value. The floor avoids discounting at the pace of a depressed market rate.
| Year | Projected earnings | Discount factor | Present value |
|---|---|---|---|
| 1 | $11.2 bn | 0.957 | $10.7 bn |
| 2 | $11.6 bn | 0.916 | $10.6 bn |
| 3 | $12.1 bn | 0.876 | $10.6 bn |
| 4 | $12.5 bn | 0.839 | $10.5 bn |
| 5 | $13 bn | 0.802 | $10.5 bn |
Reverse DCF — what growth the price discounts
The inverse approach: instead of projecting growth to obtain the value, the market price ($345) is taken as given and it solves for what annual owner-earnings growth would need to hold for 5 years for the present value —at the method's rate (4.5%, no-growth terminal)— to equal that price. It is the disconfirmation test: the expectations the price already pays for, contrasted against the method's projection.
The market discounts less growth (-12.2%/year) than we project (3.9%/year) → if the base case holds, there is margin: perception is more pessimistic than the estimated reality.
That growth implies ~$5.6 bn of owner earnings in year 5 (vs ~$13 bn of our base case). It recalculates if the DCF assumptions are edited.
Year-by-year model — bank (equity)
A bank is valued on equity (P/E × common earnings + price/tangible book), not EV: deposits and debt are funding. It returns capital via dividend + buyback —the buyback reduces the share count, so earnings per share grow faster than aggregate earnings—. Total return adds the dividend collected along the way.

An insurer is valued on equity —a multiple on earnings plus price against book value, with return on equity as the profitability measure— never on enterprise value: the float, which is invested policy reserves, is its own low-cost funding and not capital structure. The model's metric is core operating income (the measure Chubb reconciles to net income in the financial supplement of each release), not GAAP net income: the latter incorporates realized portfolio gains, market-risk benefits, and amortization of the fair-value adjustment on acquired assets, which are market movements rather than underwriting economics, and it is on core operating income that the company itself measures its return and ties management's compensation. The method's band for this type of business is calibrated on that same measure. The grid is rolling: the base year is the trailing twelve months ended June 30, 2026, read from the XBRL instance of the 10-Q filed on July 28, 2026 —the SEC's data interface has not yet ingested it— and from the financial supplement of the July 21, 2026 release. Core operating income for that trailing period is $11,516 million, built by levels (fiscal 2025 $9,954 million, plus first-half 2026 $5,531 million, minus first-half 2025 $3,969 million), and is normalized for catastrophes before being projected. The trailing-twelve-month catastrophe load was $1,625 million pretax on property and casualty net premiums earned of $47,294 million, i.e., 3.44%, well below the three-year range the annual report publishes: 4.5% in 2023, 5.5% in 2024, and 6.3% in 2025. Carried to the midpoint of that range, 5.4%, the normalized load would be $2,554 million, so the trailing period received $929 million pretax —$748 million after the period's core operating income effective tax rate, 19.4%— that does not recur. The base year comes to $10,768 million, equivalent to $27.92 per share on the 385.6 million shares outstanding at quarter-end, and to a normalized combined ratio of 84.7% versus the 82.7% actually reported. Favorable prior-period reserve development, $1,198 million or 2.53 points of the combined ratio, is not normalized: its published series climbs steadily (1.9% in 2023, 2.0% in 2024, and 2.5% in 2025) and adjusting it would imply a reversal the filing does not support. The path keeps the shape of the prior model. Chubb does not publish earnings forecasts —the search of the quarter's release and the annual report returns none— so the starting point is anchored to its own trajectory: normalized core operating income in the first half grew about 9% year-over-year, of which roughly 2.8 points are foreign exchange, putting normalized organic growth at around 6.5%. Year 1 is modeled below that figure, at 4.6%, for a reason the release itself documents: written premium, the leading indicator of earned premium, grew just 3.0% in property and casualty —6.3% excluding major accounts and E&S property— with North America Commercial at −2.3% and the major accounts and specialty business at −9.0% on property underwriting decisions; management describes "excessively soft" conditions in global property and its spread into parts of casualty and financial lines. Growth converges to 3% by year 5 as earned premium catches up to written premium and the boost from investment income moderates. The adverse scenario prolongs the soft market and adds a year of larger catastrophes; the favorable one assumes prices re-harden and float income keeps rising. The 12.5-times exit multiple on core operating income sits at the center of the method's band for a quality property and casualty insurer, 11 to 15 times, where it is placed by a wide but stable-direction moat, a return on equity well above the 10% bar, and moderate terminal growth; the implied 8% yield plus that growth covers the bar. Shares decline 2.5% a year, below the 3.3% year-over-year actually revealed (398.7 million at June 30, 2025 versus 385.6 million a year later): the trim is deliberate and reflects that the buyback was executed at an average price of $326.03 per share in the first half, near 1.7 times book value, a level that limits how much it adds per share. The base-year dividend is the amount declared over the last four quarters, $3.93 per share; year 1's is the current rate of $1.02 quarterly, $4.08 annualized, the same across the three scenarios because it is a declared fact rather than a scenario variable. The return the table shows is core operating income per share over ending book value per share: 14.3% in the base year, reproducing the 14.3% return on equity of core operating income the company published for the first half of 2026.
Today's multiple compresses on its own going forward as the metric per share grows (accelerated by the buyback, which reduces the share count). The exit multiple at 3 years is higher than the terminal at 5 years —at 3 years there is more growth still ahead—. Total return adds the dividend collected; the required return is applied to the base scenario.

Forward multiples
With today's price fixed and the metric growing, what multiple is being paid at 3 and 5 years. Today's high multiple is the price of growth: if the business grows, the entry multiple cheapens on its own.
Optionalities
They are valued separately, with their own rationale, and are not incorporated into the base or the verdict (they are excess return). When assigning them value — in Editmode —, the total with optionalities updates live, without moving the base.
The verdict, the base CAGR, and the margin of safety are always calculated on the base; optionalities do not alter them (with optionalities at $0 they do not move).
Maximum price to pay today — by required return
Each card fixes a required annual return and answers: if the business is worth $480 in 5 years, what is the maximum that can be paid today to obtain that return? Since it now trades at $345, the margin of safety is how much cheaper the market is than that maximum. The three thresholds: 4% covers inflation (the floor), 10% is the long-term average return, and 15% is the level of a great investment.

The maximum price to pay today to earn the required return, with the dividend collected as a separate flow. Both controls are editable.
With a target price of $480 in 5 years plus $24 of dividends collected (the dividend adds to the return, not to the price) and a required return of 4.5% annually, the maximum to pay today is $406. Against the current market price ($345), the margin of safety is 15.1% (trades below the maximum → there is margin) and the total return at that price would be 8.1% annually.
Valuation quality
- Multiple vs the band. ~12× core operating income (within a quality insurer's band, 11 to 15 times — reasonable) but near 2× book value, in the high end of its historical range. The earnings multiple is not expensive; the book-value multiple leaves no room for expansion.
- Near highs. It trades with no discount, with price against book value in the high end of its range. The market pays for the quality plus Berkshire's backing. Full but reasonable price.
- Margin of safety. Base case 5y ~$480 against a price of ~$345 → total return +8%/year (book value compounding plus dividend). Decent but not exceptional; little room for multiple expansion. Better bought at a cycle trough.
ROTCE vs the 10% bar — the bank's engine
The quality bar — return bands
The return on capital is judged against absolute bands; the value-creation floor is the market's opportunity cost (~10%). A stock's volatility does not measure business risk.
ROE 14% → good (10-15%). The bar is a measure of business quality, not the method's discount rate: value is discounted to today at the risk-free rate, and protection is required separately, as a margin of safety.
Quality — profitability and capital
- ROE vs the 10% bar. Return on equity of core operating income of 14.3% and on tangible equity of 20.9% in the first half — above the 10% bar. Sustained, with underwriting discipline and the float as the engines. Less volatile than an investment bank, more than a deposit-taking bank.
- Underwriting quality. The combined ratio (82.7% in the trailing twelve months, 85.7% in FY2025) is a solid technical profit, and the current-accident-year ratio excluding catastrophes is flat at 82.2%: the underlying margin did not move. Reserve development is consistently favorable, with the published series climbing. ⚠️ The 82.7% is helped by a benign catastrophe year; normalized it would be 84.7%.
- The float. $175.4bn of invested assets (a quality, unlevered portfolio) that generated $6.8bn of net investment income in the trailing twelve months, with the adjusted quarterly component hitting a record (+11.4%) — its own low-cost funding, the superpower of insurance.

Where the growth comes from · by segment
Weight in revenue and year-over-year (YoY) growth, in reported USD.
Breakdown of net premium written in the second quarter of 2026 and its year-over-year change: North America Commercial is the largest ($5,594 million, −2.3% — the soft property market, with major accounts and specialty at −9.0% on underwriting decisions and middle-market and small commercial at +8.9%), Overseas General ($3,990 million, +10.2%, or +4.8% in constant currency, with Latin America +15.6%, Asia +12.0%, and Europe +5.1%), and life ($1,937 million, +7.5%, led by Asia). The rest is high-net-worth personal ($2,054 million, +6.0%), agricultural ($776 million, +6.0%), and reinsurance ($354 million, −6.7%). The consolidated total grew 3.6%, or 2.0% in constant currency: written premium is the leading indicator of earned premium, and that is why the model's path starts below first-half growth.
Growth engine — operating drivers
Annual levels from the official filing (10-K); the % over each bar is the year-over-year (YoY) growth vs the prior year.
The engine of a property and casualty insurer is underwriting (a combined ratio below 100% is a technical profit; Chubb ran 82.7% in the trailing twelve months, or 84.7% normalized to a mid-cycle catastrophe load) plus the float (invested policy reserves, $175.4bn of invested assets, which generated $6.8bn of net investment income and whose adjusted quarterly component was a record, +11.4%). The value metric is book value per share compounding —up 12.3% year-over-year, and tangible book value up 17.1%— plus the 33-year dividend aristocrat streak. The pricing cycle is cyclical and is soft today in property, compressing premium growth; catastrophes are the inherent risk. Chubb returns capital via dividend plus buybacks, with a Board authorization of up to $5,000 million in effect since July 2025 and no expiration date.

The % are the annual (year-over-year) growth: each year —historical and projected— vs the prior one; the TTM (trailing 12m) vs the TTM of a year ago, to avoid overlapping windows. The historicals are exact figures from the official filings; the projected years come from the year-by-year model (the intermediate years without their own series are interpolated between the anchors). The projected columns (+1y…+5y) are 12-month windows counted from the TTM close (30-jun-2026): the projection starts from the most recently reported data, not the fiscal year. The projected base is realistic and unbiased — the risk discount is applied at the end, via the required return. The rationale for each metric is in the (i).
Growth quality
- Real, not nominal. Growth (earned premiums +4-5%, book value per share +12.3% year-over-year) is real: premium volume, Asia, and the float. No monetary inflation distorting it.
- Growth driver. Premium volume (life +7.5% of written premium in the quarter, led by Asia) plus rising float income plus buybacks. Book value compounding is the value engine. Modest, cyclical plus secular.
- Pricing cyclicality. The pricing cycle turned soft in property and brakes written premium growth (+3.0% in property and casualty). Book value growth moderates but does not stop; the business is defensive.
Moat strength
The business and its moat
The business: what it does and how it makes money
Chubb is a property and casualty insurer: it charges premiums in exchange for assuming risks (a factory fire, a car accident, a liability claim, a natural catastrophe) and pays claims when they occur. It makes money two ways. First, underwriting: if it collects more in premiums than it pays out in claims plus expenses, it has a technical profit, measured by the combined ratio (claims plus expenses over earned premiums). A ratio below 100% is a profit; Chubb ran 82.7% in the trailing twelve months to June 30, 2026 and 85.7% in FY2025, a level it has sustained for years, the product of demanding risk selection and pricing discipline. The current-accident-year ratio excluding catastrophes held at 82.2% versus 82.3% a year earlier: the underlying margin did not move. Second, the float: between collecting the premium and paying the claim, which can be years later, Chubb invests that money — $175.4bn of invested assets, which generated $6.8bn of net investment income in the trailing twelve months. It is the superpower of insurance that Buffett popularized: investing other people's money and keeping the return.
The economics combine both: a disciplined insurer earns from underwriting (negative-cost float) and from the yield on that float. With rates higher, the float yields more — adjusted investment income in the second quarter was a record, up 11.4%. The result is that book value per share compounds year after year: up 12.3% year-over-year, to $195.45, and tangible book value up 17.1%, to $131.93. Chubb returns the rest via dividend, with 33 consecutive years of increases, plus buybacks: $2.90bn returned to shareholders in the first half, of which $2.12bn was buybacks at an average price of $326.03 per share.
Scale and competitive position
Chubb is a large-scale global insurer: $56.7bn of net premium written in the trailing twelve months and operations in 54 countries. Its edge is not size itself —insurance is a fragmented, competitive business— but discipline and diversification. The discipline: Chubb underwrites to make money, not to grow, and the quarter shows it starkly — its major accounts and specialty business fell 9.0% in written premium on property underwriting decisions, while middle-market and small commercial grew 8.9%; management sums it up as unwilling to knowingly underwrite at a loss. That gives it a low, stable combined ratio through the cycle. The diversification: it operates in 54 countries, with a balanced mix of commercial and personal, U.S. and international — Overseas General grew written premium 10.2% in the quarter (4.8% in constant currency), with Latin America up 15.6%, Asia up 12.0%, and Europe up 5.1%, and the international life business added 14.4% more in premiums and deposits.
It competes with the large global property and casualty insurers and with specialists, plus reinsurers. The Chubb brand, inherited from the 2016 merger with ACE, is strong in commercial specialty and high-net-worth personal lines, where service and financial strength matter more than price. The moat is sustained underwriting discipline, the scale of data and actuarial models, and balance sheet strength that lets it assume large risks — but it is an execution moat, not a structural one: it depends on the underwriting culture, which in turn depends on Evan Greenberg.
The moat: why it is hard to compete
Chubb's moat is underwriting discipline plus scale plus balance sheet strength. The discipline: over decades, Chubb —and before it ACE, under Evan Greenberg— built a culture of underwriting to make money, not to grow, with a combined ratio sustained in the low-to-mid 80s that peers do not match consistently. That is not copied quickly: it requires decades of actuarial data, systems, incentives, and a culture that rewards turning down bad business. The accounting evidence of that discipline is reserve development: prior-year claims released $1,198 million in the trailing twelve months, 2.53 points of the combined ratio, and the published series climbs steadily (1.9% in 2023, 2.0% in 2024, 2.5% in 2025) — it reserved conservatively, year after year. The scale: 54 countries, a diversified mix of lines and geographies, and $175.4bn of invested assets generating rising income. The strength: a balance sheet that lets it assume large risks and absorb a mega-catastrophe without compromising the franchise.
The moat's direction is stable, with one favorable nuance —float income rises with rates— and two risks. First, pricing cyclicality: when capital is abundant, competition pushes prices down and underwriting margins compress; when catastrophes or losses drain industry capital, prices harden. The market just turned soft in property. Second, and more important: the moat is one of execution and depends on Evan Greenberg, 71, with no named successor — the underwriting culture is his legacy, and the transition is the structural risk.
Moat direction and threats
The bull case is that Chubb keeps being the compounding machine it has been: underwriting with discipline, investing the growing float, growing in Asia and in lines where price is adequate, and compounding book value per share plus the aristocrat dividend — a high-quality insurance franchise, with Berkshire as the largest disclosed shareholder in the proxy. Management frames it this way: setting aside catastrophes and foreign exchange, it is confident it can keep outperforming the industry and generate strong operating income and per-share growth, and double-digit growth in tangible book value.
The threats are three. First, the pricing cycle that turned soft: property and casualty written premium grew just 3.0% in the quarter, with North America Commercial at −2.3%, and management describes excessively soft conditions in global property already extending into parts of casualty and financial lines; a prolonged soft cycle compresses the margin. Second, catastrophes: a mega-catastrophe year hits results — the 2025 California wildfires cost $1.47bn and pushed the annual catastrophe load to 6.3 points of the combined ratio, versus 3.4 points in the current trailing twelve months. That is exactly why the model's base year is normalized to a mid-cycle load. Third, and the most structural: Evan Greenberg's succession — the discipline moat is his legacy, and at 71 with no named successor, the transition is the biggest long-term question. Above all that, valuation: it trades at around 2× book value — the quality is fully priced.
Business / sector quality
- Relevant in 10 years (recurrence). Insurance is essential and recurring (policies renew); Chubb is the quality leader. It will still be in use in 10 and in 50 years. High recurrence; pricing cyclicality is the limit.
- Pricing power. Cyclical: in a hard market Chubb raises prices; in a soft one, like today's in property, it gives up volume rather than underwrite mispriced risk — major accounts and specialty fell 9.0% in written premium in the quarter on underwriting decisions. The power lies in the discipline to turn down bad business, not in setting prices against the cycle.
- Moat and its direction. Wide moat (underwriting discipline plus scale plus float plus AA balance sheet), stable direction. But it is one of execution (the culture), which depends on Greenberg — succession is the question mark.
- Pricing cyclicality. The disconfirmer: the pricing cycle turned soft and shows in the company's own premium — property and casualty written premium grew 3.0% in the quarter and North America Commercial fell 2.3%, with the softening spreading into parts of casualty. Chubb is defensive (recurring and resilient) but the underwriting margin is cyclical.

Health — balance sheet risks
- Underwriting profitability. 82.7% combined ratio in the trailing twelve months (85.7% in FY2025) — a solid technical underwriting profit, before float income. ⚠️ Helped by a catastrophe load of 3.4 points against a three-year range of 4.5 to 6.3; normalized it would be 84.7%.
- Reserves + balance sheet. Consistently favorable reserve development (2.53 points of the combined ratio in the trailing twelve months, with the series climbing), a balance sheet of $281.3bn of assets and $75.4bn of equity, a quality, unlevered investment portfolio. Solid.
- Catastrophe exposure. A mega-catastrophe year hits results (the 2025 wildfires cost $1.47bn and pushed the annual load to 6.3 points) — the inherent risk, managed with reinsurance and diversification. The result excluding catastrophes remains very profitable: 82.2% current-accident-year ratio.
Who runs it
- Compensation is tied to the metrics of a quality insurer: the long-term incentive (performance units vesting over three years) is earned on tangible book value per share growth plus combined ratio; in 2025 the record combined ratio drove relative performance to the 97th percentile of the peer group the proxy itself defines.
- ⭐ Berkshire Hathaway (Buffett) is the largest disclosed shareholder in the proxy (8.07%) — a vote of confidence in the underwriting discipline and book value compounding. BlackRock (7.60%) is second.
- Capital allocation: in the first half of 2026 it returned $2.90bn to shareholders — $2.12bn of buybacks at an average price of $326.03 per share and $775 million of dividends. The Board authorized up to $5,000 million of buybacks in May 2025, effective July 1, 2025 with no expiration date, of which $2,100 million remained as of February 26, 2026. The dividend has 33 consecutive years of increases.

Management / capital allocation
- Skin in the game. Greenberg holds shares significant in dollar terms (though <1%); insiders <1%. ⭐ Berkshire Hathaway (Buffett) is the largest disclosed shareholder in the proxy (8.07%) — a strong vote of confidence in the franchise.
- Capital allocation. Reinvests at a core operating income return on equity of 14.3% (grows book value) and returns the rest: $775 million of dividends and $2.12bn of buybacks in the first half, against an authorization of up to $5,000 million. Buying back near 2× book value is expensive but modest.
- Execution / integrity. Greenberg built the underwriting discipline over more than twenty years (a combined ratio sustained in the low-to-mid 80s, consistently favorable reserve development). ⚠️ Succession (71, no named successor) is the continuity risk to that culture.
Why it trades at this price
- It is neither cheap nor expensive: it trades at ~12× core operating income —within the method's band for this type of business— but at around 2× book value, with no discount.
- The market already recognizes the quality: a combined ratio sustained in the low-to-mid 80s, a float yielding increasingly more (record adjusted investment income in the quarter, +11.4%), 33 years of dividends, and Buffett as the largest disclosed shareholder. It is priced fairly.
- The soft property market is a headwind visible in the company's own premium —property and casualty written premium grew 3.0% in the quarter, with North America Commercial at −2.3%— and that tempers enthusiasm; but the business is recurring and book value per share still compounded 12.3% year-over-year.
Chubb is neither a bargain nor overvalued: it is a great business at a fair price. The taxonomy of why a stock trades cheap does not fully apply here — there are no missing buyers (it is a blue-chip name with Berkshire as a shareholder) nor motivated sellers, and price against book value in the high end of its range says the quality is fully priced. Nor is it a case of stacked optimism like expensive cyclicals: the multiple on core operating income is reasonable, the business is defensive, book value compounds, and the dividend carries part of the return. There is one caveat the filing itself requires: the trailing-twelve-month result is helped by a catastrophe load of 3.4 points against a three-year range of 4.5 to 6.3, so the multiple one sees on reported earnings is lower than what corresponds to normalized earnings — the model uses the normalized figure, precisely to avoid mistaking a benign year for a bargain. The read: a superb compounder at fair value, with a decent but not exceptional total return, and little room for multiple expansion from an already full level. The best entry is a pricing-cycle trough or a catastrophe scare.
Return asymmetry — risk/reward
The annual return (CAGR at 5 years) in each scenario, with the total period return below — the margin of safety made visual: upside range wide, downside range narrow.
Even in the bear scenario, the return holds at +1%/year (+6% total): the margin of safety protects the downside. The bull (+14%/year, +94% total) exceeds it comfortably — a favorable asymmetry, with a narrow downside range and a wide upside range.
Bear case — disconfirmation
- The soft property market persists and spreads: property and casualty written premium already grew just 3.0% in the quarter, with North America Commercial at −2.3%, and management describes the softening reaching parts of casualty and financial lines. If the current-accident-year ratio excluding catastrophes —flat today at 82.2%— starts rising, the underwriting margin compresses for real.
- A mega-catastrophe year hits results, like the 2025 California wildfires ($1.47bn, 6.3 points of annual load versus 3.4 in the trailing twelve months) — the inherent volatility of a property and casualty insurer, and the reason the base year is normalized.
- The multiple reverts from the high end of its book-value range toward its mean, without a still-larger earnings figure to offset it: compression alone limits the return.
- Favorable reserve development stops or reverses: it contributed 2.53 points of the combined ratio in the trailing twelve months and has been rising, so a reversal would subtract exactly where the result is most supported today.
- Evan Greenberg's succession (71, no named successor): if the transition erodes the underwriting-discipline culture, the moat weakens — the long-term structural risk.
Bull case — the thesis for
- Property prices re-harden sooner than expected, due to catastrophes or industry losses draining capital: Chubb recovers the volume it is giving up today —major accounts and specialty fell 9.0% in the quarter on underwriting decisions— and management states that this growth headwind will fade.
- The float ($175.4bn of invested assets, up 9% over twelve months) is reinvested at higher yields as long as rates stay high: adjusted investment income already hit a record $1.88bn in the quarter, +11.4%, a structural tailwind the base case captures only partly.
- Growth in Asia compounds: life premiums and deposits rose 14.4% in the quarter and the segment's result grew 9.0%, diversifying the cyclical underwriting business and adding a secular growth engine to book value.
- The multiple expands toward the high end of the band recognizing underwriting quality, tangible book value compounding —up 17.1% year-over-year—, and Berkshire's backing.
Risks — what breaks the base case
- Soft pricing cycle. The central disconfirmer: the market turned soft in property and already shows in the company's own premium (property and casualty written premium +3.0%, North America Commercial −2.3%, major accounts −9.0% on underwriting decisions), spreading into parts of casualty. A prolonged soft cycle pushes up the combined ratio.
- Greenberg's succession. At 71 with no successor named, the underwriting discipline culture (his legacy, the moat) faces transition risk — the long-term structural question.
- Catastrophes. A mega-catastrophe year hits results — the inherent volatility of a property and casualty insurer, managed with reinsurance and diversification. The trailing twelve months ran at a 3.4-point load against a three-year range of 4.5 to 6.3, so the reported result is helped; the model normalizes the base year to 5.4 points.
- Valuation in the high end of the range. Price against book value of around 2×, in the high end of its historical range — little room for multiple expansion, and a reversion would be a headwind to the return.

Each thinker's analytical framework applied to our data.
Full alignment: both the business and the price work in your favor.
- Buffett / Graham Quality + margin of safety
A wide moat and ROE 14% above the 10% bar, but the margin is limited (+15%) → excellent business at a fair price.
- Peter Lynch Growth at a reasonable price (GARP)
A stalwart growing 4% at a PEG of 3.2 → expensive for its growth.
- Joel Greenblatt Cheap and high-return (Magic Formula)
Not applicable — the Magic Formula excludes financials and regulated businesses (EBIT/EV does not capture the operating leverage).
- Howard Marks Perception vs reality + cycle
The price discounts -12% vs our 4%: perception is more pessimistic than reality, with an identified source of the discount.
- Seth Klarman Capital protection (bear scenario)
Bear-scenario floor -0%/yr, bull-scenario ceiling +13%/yr over 5y → capital protected, asymmetry in your favor.
- Pat Dorsey Moat strength (Five Rules)
A wide moat, stable; sources: intangibles, efficient scale, cost advantage, switching costs → passes the Five Rules.
- Aswath Damodaran Expectations implied by the price
Justifying the price requires discounting -12%, within what we project (4%) — the story squares with the numbers.
