BASFY vs LYB: 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: LYB 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. BASFY and LYB 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 BASFY and LYB 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.

BASF SE, headquartered in Ludwigshafen, Germany, is the largest chemical producer in the world by sales, with group revenue of about €59.7 billion in 2025. It makes the building blocks of modern industry: basic chemicals and petrochemicals from its integrated Verbund sites, engineering plastics and polyurethanes, battery and catalyst materials, nutrition and personal care ingredients, and crop protection products and seeds through its Agricultural Solutions division. The Verbund model, in which plants at a single site feed each other's by-products and energy, is the company's core competitive idea, and Ludwigshafen is the largest integrated chemical complex on earth. In 2025 BASF started up the main plants at a new Verbund site in Zhanjiang, China, a roughly €8.7 billion bet that the world's biggest chemical market will keep growing. The US-traded BASFY is a sponsored Level I ADR on OTCQX, with BNY Mellon as depositary and four ADRs representing one ordinary share listed on Xetra under the ticker BAS.

LyondellBasell Industries is a Netherlands-domiciled, US-listed multinational and one of the largest plastics, chemicals, and refining companies in the world. Its business is organized around Olefins and Polyolefins in the Americas and in Europe/Asia/International, an Intermediates and Derivatives segment, Advanced Polymer Solutions, and a Refining operation the company has been winding down. The core products are the building blocks of everyday plastics (polyethylene and polypropylene) plus propylene oxide, oxyfuels, and other intermediates, so results move with feedstock costs, product spreads, and regional demand rather than with a single end market.

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

• BASFY drivers: Earnings recovery and raised 2026 guidance; Portfolio reshaping: coatings out, agriculture toward an IPO.
• LYB drivers: Cycle recovery in polyolefins; Portfolio reshaping and refining exit.

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: BASF is a cyclical company, and chemical prices, volumes and margins can turn quickly with industrial production, construction and auto demand, so a strong quarter can reverse within a year. For LYB, lYB is deeply cyclical, so a prolonged glut in global petrochemical capacity, especially new supply from the Middle East and China, can keep polyolefin spreads compressed and earnings depressed.

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 BASFY if you believe its drivers more; LYB 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 BASFY and LYB guides.

BASFY. BASF shares traded around €53 in early autumn 2026, which puts the ADR in the mid-teens in dollars given the four-for-one ratio. On the guided 2026 EBITDA before special items, the stock trades at a mid-single-digit EV/EBITDA multiple once net debt and pensions are added back, which is typical for European commodity-heavy chemical producers and cheaper than US specialty peers. Reported net income in 2026 is inflated by the roughly €3.9 billion coatings disposal gain, so trailing P/E figures quoted on data sites can look misleadingly low and are best read alongside the underlying EBITDA trend.

LYB. Figures are approximate and as of October 16, 2026. Trailing GAAP earnings are still negative because the window includes 2025's losses, so the stock trades on a ~10x forward P/E, ~0.7x sales, and ~9x EV/EBITDA rather than a clean trailing multiple. The average target across 18 analysts is about $67.61 with a consensus hold, and the October 30 Q3 report will show how much of the Q2 margin spike carried into the second half.

Headline figures (approximate, October 2026): BASFY shows revenue (fy 2025) ~€59.7B (~$69B), ebitda before special items (fy 2025) ~€6.6B, 2026 ebitda before special items guidance €6.9B to €7.7B (raised in July), q2 2026 sales / ebitda bsi ~€17.2B / ~€2.4B; LYB shows share price / market cap ~$63.47 / ~$20.5B, revenue (ttm) ~$31.2B; Q2 2026 revenue ~$9.18B, up ~20% year over year, q2 2026 adjusted eps ~$4.30 vs ~$3.42 expected, net income (ttm) ~-$265M GAAP (2025 losses still in the window); Q2 2026 net income ~$558M.

BASFY and LYB 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.
