Chubb

Chubb is the property-and-casualty insurance company Warren Buffett bought in plain sight during 2023 — and most of Wall Street missed it. Berkshire Hathaway's confidential 13F treatment hid the position for two quarters before disclosing 26M shares (~$7B) in Q1/2024. As of Q1/2026, the stake has grown to 27.1M shares (~$8.6B). Buffett rarely buys insurance — Berkshire is already the largest P&C insurer in the world via GEICO and General Re — which makes the Chubb position the strongest possible peer endorsement.

The 2026 story is the hard-market price cycle continuing into Year 5. Chubb's North American Commercial premiums grew +9.4% in Q1/2026 at a 86.1% combined ratio — meaning every $100 of premium produced $14 of underwriting profit before investment income. The S&P 500 P&C average combined ratio is 96.5. Chubb has outperformed the industry combined ratio by 10+ points every year since 2018 — a moat that compounds.

What investors miss is the bond-portfolio kicker. Chubb holds $130B in fixed-income securities at a 4.9% book yield (up from 3.2% in 2022). The reinvestment math alone adds $2B+ to annual investment income through 2028 versus the pre-Fed-hike base. That is pure earnings tailwind with no operational risk attached.

Berkshire Hathaway built the Chubb position over three quarters in 2023 with confidential SEC filing treatment — a privilege Buffett uses only when he plans to keep buying and does not want price-front-running. The position was revealed in May 2024 13F-HR at 26.0M shares ($6.7B). As of Q1/2026, Berkshire holds 27.1M shares (~$8.6B value) — adds of 1.1M shares net over 24 months. Berkshire has not trimmed.

Notable other holders: Capital Group (61M shares, +4% in Q1/2026), Vanguard (52M shares), BlackRock (49M shares). Active manager adds include Fidelity Contrafund (Bill Danoff, +1.2M shares in Q1/2026) and First Eagle Global Value (+800K). No top-20 holder has been a net seller in the past 2 quarters.

Insider activity (Form 4): CEO Evan Greenberg has not sold a share since 2017 (extremely unusual for a CEO of his tenure). CFO Peter Enns sold 30,000 shares in March 2026 at $338 (routine 10b5-1 plan). Greenberg owns 1.8M shares personally — an insider with skin in the game on a level rarely seen in large-cap financials.

Chubb trades at a forward P/E of 10.9× and price-to-book of 1.7× as of May 2026. Comparable P&C insurance peers — Travelers (12×), AIG (13×), Allstate (11×), and Progressive (16×) — bracket Chubb in the middle of the pack. The bull case (Wells Fargo, Goldman Sachs) values Chubb at 13× forward P/E given the hard-market durability and bond-portfolio tailwind — implying $375-385. The bear case (Morgan Stanley) sees the 2027 cycle turn compressing the multiple to 9× — implying $290-300. Wall Street analyst targets range from $291 (Morgan Stanley) to $385 (Wells Fargo), median $345 vs. current $320 — implying 8% upside. The 1.2% dividend plus $5B 2026 buyback authorization (4% buyback yield) makes total capital return competitive with REITs.

2. September-November 2026: Atlantic hurricane season peak — single major landfall in Florida or Texas is the largest binary risk
3. November 2026: Q3/2026 earnings + 2027 guidance — first formal management commentary on when management expects the hard-market cycle to turn

Chubb is one of those rare 'compound at 10-12% with low drama' positions in my portfolio. I bought my first Chubb shares in 2022 at $215 and have not trimmed — partly because Evan Greenberg is the most disciplined CEO in the insurance industry, partly because Berkshire's confidential-treatment buy was the loudest possible non-verbal signal I could imagine. What I do NOT love at the current $320 is the proximity to the 2027 cycle turn — Chubb at 11× forward is fairly priced, not cheap. My add-trigger is below $280 (a post-hurricane or cycle-turn pullback) — at which point I would add aggressively. The bond-portfolio reinvestment tailwind is the under-discussed thesis here, and it pays you to wait.
