NEU vs SHEL: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of September 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: SHEL 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. NEU and SHEL 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 NEU and SHEL 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.

NewMarket Corporation is a Richmond, Virginia holding company that operates primarily through Afton Chemical and Ethyl Corporation, which develop, blend, and sell chemical additives that improve the performance of engine oils, transmission fluids, and fuels. The additives are a small fraction of the cost of the finished lubricant but are technically critical, which gives the business unusually sticky customer relationships and consistent margins. More recently the company has built out a smaller Specialty Materials segment (including the AMPAC and Calca acquisitions) that touches areas such as specialty ammonium perchlorate and other niche materials.

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

• NEU drivers: Margin resilience and mix discipline; Cash generation and capital returns.
• SHEL drivers: LNG and Integrated Gas leadership; Shareholder returns: dividend and buybacks.

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: Petroleum additives demand is tied to global lubricant and fuel consumption, so a soft industrial and automotive environment directly pressures shipments, as seen in recent quarters. For SHEL, as an integrated energy major, Shell's earnings rise and fall with oil, gas, and LNG prices and with refining and chemical margins, so a downturn in commodity prices or global demand can compress profits and pressure cash returns.

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 NEU if you believe its drivers more; SHEL 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 NEU and SHEL guides.

NEU. NewMarket carries a mid-teens P/E, in line with a mature specialty chemicals name that grows slowly but returns lots of cash. Full-year 2025 net income of about $419 million was down from 2024, and Q1 2026 continued the softer trend with revenue near $670 million. The valuation reflects steady margins and capital returns rather than expectations of rapid growth.

SHEL. These figures are approximate and tied to the asOf date; verify live numbers before acting. Because each SHEL ADR represents two Shell ordinary shares, per-ADR dividend and earnings figures are roughly double the per-ordinary-share numbers you may see quoted from London or the Netherlands, so make sure you are comparing like for like. As with any integrated energy company, earnings and multiples move with the commodity cycle, so a given quarter's results reflect prevailing oil, gas, and margin conditions rather than a fixed run-rate.

Headline figures (approximate, JULY 2026): NEU shows revenue (ttm) ~$2.7B, net income (fy2025) ~$419M, diluted eps (fy2025) ~$44.44, q1 2026 net income ~$118M (~$12.62/sh); SHEL shows q1 2026 eps ~$2.44, above the analyst consensus of about $2.14, q1 2026 revenue ~$70 billion for the quarter, dividend Progressive quarterly dividend; the ADR receives roughly double the per-ordinary-share amount (each ADR is two ordinary shares), payout ratio Roughly half of earnings historically, leaving room for buybacks.

NEU and SHEL 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.
