COP vs DUK: 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: COP 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. COP and DUK 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 COP and DUK 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.

ConocoPhillips (NYSE: COP) is an exploration and production (E&P) company focused exclusively on the upstream segment of the oil and gas industry. It finds, develops, and produces crude oil, natural gas, and natural gas liquids from a globally diversified asset base that includes U.S. Lower 48 shale plays (Permian, Eagle Ford, Bakken), Alaska (including the Willow development project), Canadian oil sands at Surmont, operations in Norway and Qatar, and equity stakes in LNG projects including Australia Pacific LNG and the Port Arthur LNG facility on the U.S. Gulf Coast. The company makes money by selling the hydrocarbons it produces at prevailing market prices, with profitability driven primarily by realized commodity prices, production volumes, and its cost-of-supply discipline. It does not operate refineries or fuel retail networks, giving it a focused capital structure but also direct exposure to commodity price swings.

Duke Energy is a holding company for a group of regulated electric and gas utilities serving roughly eight and a half million electric customers across six states, including the Carolinas, Florida, Indiana, Ohio, Kentucky, and Tennessee, plus natural gas distribution to over a million customers. As a regulated utility, Duke earns an authorized return on the capital it invests in power plants, poles, wires, and pipes, so its profit grows largely as it grows its regulated asset base, or rate base, subject to approval from state utility commissions. This regulated model produces relatively stable, predictable cash flows that fund a long-running dividend, which is the core of the income case for the stock.

Full DUK guide

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

• COP drivers: Marathon Oil Integration and Scale; Willow Project and Long-Cycle Growth.
• DUK drivers: Rate-base growth from a $103B capital plan; Data-center and large-load demand.

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: COP's revenues and free cash flow are highly sensitive to crude oil and natural gas prices, and the 2026 surge cuts both ways: second quarter earnings roughly doubled year over year, and analysts already model 2027 EPS about 7% below 2026, so a commodity pullback would hit a stock that has gained ~50% this year. For DUK, duke is highly capital-intensive and carries substantial debt to fund its build-out, which makes it sensitive to interest rates: higher rates raise its borrowing costs and tend to compress the valuations investors assign to regulated utilities, while also making bond yields more competitive with its dividend.

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 COP if you believe its drivers more; DUK 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 COP and DUK guides.

COP. COP's trailing P/E near 19x still sits well above its own 10-year median of around 12x, but the forward P/E near 14x shows how much of the gap is earnings catching up: analysts expect about $11.24 of 2026 EPS, up from $6.34 in 2025. Free cash flow of roughly $7.7 billion over the trailing twelve months has improved but still reflects heavy spending on Willow and LNG, with management projecting a material step-up toward 2029. With 26 analysts carrying a mean target near $149, only a few percent above the October price, much of the commodity rally is already in the valuation.

DUK. As of October 16, 2026, DUK closed near $121 per share with a market cap around ~$94 billion, below the high-$120s of late June. The trailing P/E of about ~18x and forward P/E near ~17x are broadly in line with large regulated-utility peers. Q2 2026 EPS was ~$1.43 against a ~$1.30 estimate, and consensus for the September quarter, reported November 5, 2026, is about ~$1.83 on roughly ~$8.9 billion of revenue. Figures are approximate, drawn from public market data, and move with the share price.

Headline figures (approximate, October 2026): COP shows revenue (ttm) ~$64.5 billion (Q2 2026 +35.5% YoY), net income (ttm) ~$9.25 billion, eps (trailing / forward) ~$7.55 / ~$10.52, p/e ratio (trailing / forward) ~19x / ~14x; DUK shows revenue (ttm) ~$32.8B, revenue growth (latest quarter, yoy) ~1%, net income (ttm) ~$5.2B (~16% margin), adjusted eps guidance (fy2026) ~$6.55 to ~$6.80.

COP and DUK 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. Walnut can show your combined COP and DUK exposure against your real portfolio. It is not an investment adviser.
