Chubb Limited (CB)

Chubb is the world's largest publicly traded P&C insurer — a disciplined underwriting machine (record 85.7% combined ratio, best-in-class) plus a $169bn float that earns more with rates high. Globally diversified (54 countries, commercial plus personal plus Life in Asia). Book value per share compounds ~8-10%/year plus a dividend-aristocrat payout (33 years). The moat is underwriting discipline plus scale plus balance-sheet strength (AA), but it is one of execution — it depends on Evan Greenberg's culture (71, no successor named). Berkshire is the largest shareholder.

An insurer is valued on equity —P/book plus P/E on earnings, with ROE as the profitability metric—, never by EV: the float (the invested reserves) is low-cost proprietary funding, not capital structure. At ~$342, Chubb trades at ~12× earnings and at 2× book value — the top of its historical range of 1.5-1.9×, near highs.

The base case projects earnings growing ~5%/year (premium growth plus float income rising with rates, moderated by the pricing cycle turning soft), a buyback reducing the share count ~2.5%/year, and an exit multiple of ~12.5× earnings (in line with its current level, without assuming expansion from the top of the book-value range). Book value compounds ~8%/year. That gives ~$479/share; adding the dividend (~1.1%), the total return is +8%/year. It is a quality compounder at a full but reasonable price — the ~12.5× P/E is not expensive, but the P/book at the top of the range leaves little re-rating margin.

It trades close to intrinsic value, far from the required margin of safety. At ~$342, near all-time highs, Chubb is a superb compounder at a full but reasonable price. The verdict is Fairly valued: the quality is beyond dispute (the best underwriting discipline in the sector, a growing float, 33 years of dividends, Buffett as the largest shareholder), and the price is not expensive in earnings terms (~12.5× earnings), but it is at the top of its book-value range (2×) — there is no discount, and the pricing cycle turning soft is a headwind to the underwriting margin. The total return (+8%/year) is decent but not exceptional: book value compounding (~8%) plus the dividend, with little re-rating margin from an already full multiple. The adverse scenario (a prolonged soft cycle plus a mega-catastrophe year plus a de-rating) has limited downside (insurance is recurring and resilient in a recession); the favorable one (pricing re-hardens plus the float surges plus a re-rating) is clear upside. Value discipline says this is a great company at a fair price — better bought in a trough of the cycle or a catastrophe scare than near highs.

Three things. The P&C pricing cycle (the central disconfirmation) — the market has turned soft (industry commercial rates −1.2% in Q1'26); if the softening persists, the combined ratio rises and the underwriting margin compresses; if prices re-harden (due to catastrophes or losses), the margin expands. Evan Greenberg's succession — at 71 with no successor named, the disciplined underwriting culture is his legacy, and the transition is the biggest structural question. And catastrophes plus float income — a mega-catastrophe year hits results (the 2025 wildfires cost $1.5bn), but ex-catastrophe results remain very profitable; and the float ($169bn) earns more with higher rates — the investment engine. At this price (the top of the book-value range), the best entry comes with a cycle trough or a catastrophe scare — not near highs.
