AIG vs ALIZY: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: AIG is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AIG and ALIZY share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AIG and ALIZY exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

American International Group, Inc. (AIG) is a leading global insurance organization that helps businesses and individuals protect assets and manage risk across more than 200 countries and jurisdictions. Its core is general insurance: property, casualty, financial lines, and specialty coverage for mid-sized companies and large multinationals, plus personal lines. The business model is the classic insurance one: collect premiums, manage the underlying risk through disciplined underwriting and reinsurance, and invest the float in fixed income and other securities. Profit comes from two engines, an underwriting result (premiums earned minus claims and expenses) and investment income on the portfolio.

Allianz SE is one of the largest insurance and asset-management groups in the world, headquartered in Munich and listed on the Frankfurt (Xetra) exchange under the symbol ALV. It runs three businesses. Property-Casualty sells motor, home, commercial and specialty cover across Europe, Australia, Latin America and Asia, plus global corporate risk through Allianz Commercial and travel and assistance through Allianz Partners. Life/Health sells savings, protection, annuity and health products, with Germany, the US (Allianz Life) and Italy among the biggest markets. Asset Management is PIMCO, the fixed-income specialist, and Allianz Global Investors, which together oversee roughly EUR 2.16 trillion of third-party money. ALIZY is the US dollar American depositary receipt that trades over the counter, with each ADR representing one tenth of an ordinary share.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AIG drivers: Pure-play P&C focus after Corebridge; Underwriting discipline and combined ratio.
• ALIZY drivers: Property-Casualty pricing and underwriting discipline; PIMCO and the asset-management flow cycle.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The central risk is that AIG is now a more concentrated property and casualty insurer, so a softening commercial pricing cycle can compress underwriting margins just as competition intensifies; management itself now calls the market more selective. For ALIZY, natural catastrophes are the most visible risk: a severe European storm or flood season, wildfire or hurricane losses can push the P&C combined ratio up several points in a single quarter.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AIG if you believe its drivers more; ALIZY if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AIG and ALIZY guides.

AIG. These figures are approximate and tied to the as-of date; verify live numbers before acting. Insurers are best judged on combined ratio, book value growth, and return on equity rather than a simple P/E, because reported earnings swing with catastrophe timing, reserve movements and investment marks (Q2 2026 GAAP EPS of $1.78 fell 10% even as adjusted EPS rose 10%, mostly because of Corebridge and equity fair-value changes). At about one times book and nine times forward earnings, AIG is priced below premium underwriters like Chubb. Third-quarter results are due November 3, 2026, with consensus near $1.87 of adjusted EPS.

ALIZY. At roughly EUR 420 per Frankfurt share, Allianz is valued at around EUR 160 billion and trades near 14 to 15 times 2025 core earnings and closer to 13 times what the first-half run rate implies, with a dividend yield around 4%. Those multiples sit at the upper end of where European composite insurers have traded historically, reflecting record profit, a ~20% core return on equity and strong capital, but they are below many US insurers and asset managers. Allianz does not report a conventional revenue line; total business volume (premiums plus asset-management fees) is the closest equivalent, so price-to-sales comparisons with non-insurers are not meaningful.

Headline figures (approximate, October 2026): AIG shows revenue (ttm) ~$26.7B; Q2 2026 General Insurance net premiums written ~$7.5B (+9% YoY), combined ratio 89.0% in Q2 2026 (accident-year, as adjusted, 88.1%), both 30 bps better year over year, net income / adjusted eps Net income ~$3.0B TTM; Q2 2026 adjusted after-tax EPS $2.00 (+10% YoY, vs ~$1.93 expected), book value and returns Book value ~$77.39 per share at June 30, 2026 (+4% YoY); core operating ROE ~11.1%; ALIZY shows total business volume (2025) ~EUR 185bn (~USD 205bn), operating profit (2025) ~EUR 17.4bn, up ~8%, operating profit (1h 2026) ~EUR 9.4bn, up ~9%, core eps (2025) ~EUR 28.61, up ~12.5%.

AIG and ALIZY are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
