A snapshot of market cap data from GlobalData;
The world’s largest insurers are undergoing a sharp market-cap rotation, with investors favoring businesses that can combine disciplined underwriting, resilient investment income and capital generation. Asian life insurers and leading P&C players are gaining ground, while healthcare and selected global insurers face pressure from medical-cost inflation, catastrophe losses and shifting interest-rate expectations, according to GlobalData, a leading intelligence and productivity platform.
Fubon Financial, Cathay Financial, Great-West Lifeco and Manulife were among the biggest year-on-year winners, while Progressive, LIC, UnitedHealth and Munich Re lost ground.
At 31% of the group and 3.2 times UnitedHealth‘s value, Berkshire (-1.1%) anchors the ranking. But insurance underwriting and investment income produced only about $4.8 billion of its $13.0 billion second-quarter operating earnings, and both lines fell year-on-year (YoY). Rail, energy and manufacturing carried the quarter. Management repurchased $4.5 billion of stock in the quarter and $3.3 billion more in July, with $365 billion of cash still on hand.
Murthy Grandhi, Company Profiles Analyst at GlobalData, comments: “UnitedHealth fell 12.7%, while Elevance (+0.4%) and Cigna (-1.5%), with less or no Medicare Advantage exposure, held. UnitedHealth is the largest operator in that business, with more than 8 million members. Washington proposed a 2027 payment increase of just 0.09%, the company guided 2026 revenue down about 2%, and September brought a managed-care selloff over medical costs. UnitedHealth and Humana are now dropping plans that cover roughly a million seniors in 2027.”
The strongest P&C stories are elsewhere. Tokio Marine gained 22.2% YoY and 15% quarter-on-quarter (QoQ), while Travelers climbed 18.3% YoY. Travelers’ second-quarter combined ratio improved to 83.6%, helped by lower catastrophe losses, favorable reserve development and higher investment income. Its fixed-income portfolio generated $1.07 billion of pre-tax investment income, up 14%. This highlights an important feature of today’s insurance market: higher yields are effectively a second underwriting engine for insurers holding large bond portfolios.
Chubb, despite a 5.1% QoQ decline, remains fundamentally strong, with second-quarter core operating income up 14.6%, P&C underwriting income up 18.8% and a combined ratio of 83.8%. Investment income also reached a record $1.88 billion. The share-price decline therefore looks more like valuation digestion than deterioration in operating fundamentals.
Grandhi adds: “The Asian life-insurance complex tells another story. Fubon (+15.5%) and Cathay (+12.1%) are worth a combined $123 billion, more than Zurich, and up 57% in a year. Their life arms hold Taiwanese and US equities, so the AI-driven rally lifted fair-value gains. Tokio Marine (+15.0%) rose to tenth on a JPY200 billion buyback and an announced stock split. India’s LIC (-10.0%) moved the other way. The government’s August sale of up to 6.5% at a floor price 10% below market added supply, and the rupee, near 96 per dollar, trims dollar value.”
Allianz was flat (-0.2%) and AXA slipped 3.8%. Zurich fell 9.8% as it prepared to close its $10.7 billion cash purchase of Beazley on October 1. Munich Re (+2.1%) and Swiss Re (+4.1%) rose but remain down 13% and 10% on the year.
Grandhi concludes: “GlobalData anticipates that the next quarter will be governed by three forces: medical-cost inflation, catastrophe losses and interest rates. The latter remains particularly important because insurers are major fixed-income investors. But higher yields are not universally positive: they improve reinvestment income while simultaneously creating mark-to-market volatility and potentially weakening economic activity.
“Geopolitical risk adds another layer. War-related inflation, elevated energy prices, supply-chain disruption and increasingly severe natural catastrophes could lift claims costs even as they increase demand for commercial, specialty and reinsurance coverage.”
