Chubb Limited

Chubb Limited is a Swiss-incorporated global property and casualty insurance and reinsurance organization that operates in 54 countries and territories, generating $59.4 billion in total revenues and $10.3 billion in net income attributable to shareholders in fiscal 2025. It is one of the world's largest publicly traded P&C insurers, with $272 billion in total assets, $169 billion in invested assets, and $74 billion in shareholders' equity as of December 31, 2025.

This is a story about an underwriting franchise that has compounded shareholder wealth across decades and market cycles through obsessive discipline, global diversification, and a balance sheet that earns from both sides — underwriting profit on the liability side and investment income on the asset side. Chubb is not a growth story in the conventional sense; it is a risk-selection story, and the question that animates this file is whether the cycle-tested machine can sustain its return profile as commercial P&C pricing softens and casualty loss costs grind steadily higher.

The bull case for Chubb does not require a hard market. It requires that the company's diversification — across geography, product, commercial and consumer customers, and distribution channel — allows it to continue earning an underwriting profit while the $175 billion investment portfolio compounds at structurally higher yields. The bear case is that insurance cycles are inevitable and Chubb, for all its discipline, cannot fully escape them. The file turns on a single question: can the company sustain its mid-teens ROE and double-digit tangible book value growth through the softening cycle now underway in commercial P&C?
