The Berkshire Hathaway of Insurance
Chubb traces its roots to 1882 when sea captain Thomas Caldecot Chubb and his son Percy opened an insurance agency in New York. After 140 years and multiple mergers (most notably acquiring ACE Limited in 2016), Evan Greenberg leads a company underwriting $50 billion in annual premiums across commercial insurance (60% of premiums), personal lines (25%), and reinsurance (15%). Chubb's specialty: complex, high-value risks requiring deep underwriting expertise. The company insures cyber breaches for retailers (Target's $18.5M cyber claim paid by Chubb), political risk for multinational corporations, marine cargo for global shipping, and fine art for museums. This isn't commodity insurance—Chubb evaluates each risk individually, pricing based on loss probability rather than competing on premium volume. The result: combined ratios 10-12 points better than mass-market competitors, translating to $5-6 billion in annual underwriting profit before investment income.
Business Model & Competitive Moat
Chubb's moat is underwriting discipline and distribution relationships. First, pricing power: Chubb underwrites risks competitors can't or won't (kidnap & ransom, political violence, cyber for critical infrastructure). This specialization allows 10-20% premium pricing above commodity markets. Second, distribution: Chubb works through independent brokers (Marsh, Aon, Willis Towers Watson) who value Chubb's claims-paying reliability and complex risk expertise. Third, brand strength among high-net-worth individuals—owning a Chubb policy signals financial success (like driving a Mercedes). Fourth, investment portfolio: $70 billion invested in high-grade bonds, equities, and alternatives yielding 4.5%, adding $3+ billion in annual income. Unlike banks, insurance float (premiums collected before claims paid) provides permanent capital for investments. Greenberg's strategy maximizes float quality by targeting long-tail commercial lines (claims paid years after premiums collected), creating durable investment advantages. The weak point: catastrophe exposure—hurricanes, earthquakes can generate $2-5 billion in annual losses, though Chubb's reinsurance program caps downside.

- ✓Conservative dividend investors seeking 2.1% yield + capital appreciation

- ✓Inflation hedges (premiums rise with inflation, asset values protected)
Less Suitable For
- ✗Growth investors (8-10% revenue growth vs. 15%+ for tech)

Investment Thesis
Chubb represents insurance sector excellence: best-in-class underwriting combined with investment portfolio strength. At 1.6x book value, the stock trades at a premium to peers (typical P&C insurers trade at 1-1.2x book) but reflects quality—Chubb's 88% combined ratio and 14% ROE justify premium valuations. The investment thesis: Chubb compounds book value at 10% annually through superior underwriting + investment income, creating 12-15% total returns (book value growth + 2.1% dividend). Near-term catalysts include commercial rate hardening (premium growth accelerating), rising investment yields (adding $500M+ annually), and international expansion. Risks are manageable—catastrophe reinsurance caps downside, diversified book limits concentration, and Greenberg's 20-year track record demonstrates through-cycle resilience. For conservative investors seeking quality compounding with defensive characteristics, Chubb offers Berkshire-like insurance economics in a dividend-paying package. This is a core holding for balanced portfolios, sized at 3-5% for long-term wealth preservation and growth.
