COP vs OXY: 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.

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 OXY 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 OXY 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.

Occidental Petroleum (Oxy) is a large US-based oil and gas company. Upstream exploration and production is the core: Oxy finds and produces crude oil and natural gas, with a flagship position in the Permian Basin, the most prolific US oil field, plus operations in the Rocky Mountains, the Gulf of America, and internationally in the Middle East and North Africa. A midstream and marketing segment moves and sells its barrels and holds an equity stake in Western Midstream (WES). Oxy is also building a carbon-management business through its 1PointFive subsidiary, developing direct air capture (DAC) facilities that pull CO2 from the atmosphere. Until January 2, 2026 it also owned OxyChem, a major chlor-alkali and PVC chemicals producer; that business was sold to Berkshire Hathaway for $9.7 billion in cash, with an Oxy subsidiary retaining OxyChem's legacy tort and environmental liabilities. Oxy is notable for Berkshire's large ownership stake and for its 2019 acquisition of Anadarko, which left it heavily indebted. Headquartered in Houston, Texas, Oxy is now led by President and CEO Richard Jackson, who succeeded Vicki Hollub during 2026.

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.
• OXY drivers: Permian Basin scale; Debt reduction and capital return.

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 OXY, oxy's earnings and cash flow are highly sensitive to oil and gas prices, which are volatile and outside its control.

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; OXY 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 OXY 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.

OXY. At $61.26 on October 16, 2026, Oxy trades near 17 times trailing and 13 times forward earnings, with the forward figure resting on consensus EPS of about $4.71 for 2027 after a high-price 2026. Valuation is dominated by oil-price sensitivity and balance-sheet repair: the OxyChem proceeds and Q2's $3.0 billion of free cash flow before working capital sped up debt reduction, while carbon capture adds long-dated optionality. Mean analyst targets sit near $69.

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; OXY shows revenue (ttm) ~$24 billion; Q2 2026 ~$8.3 billion (up ~53% YoY), net income (ttm) ~$3.4 billion, EPS ~$3.52, operating margin ~45% (TTM), highly oil-price dependent, production (q2 2026) ~1,433 thousand barrels of oil equivalent per day.

COP and OXY 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 OXY exposure against your real portfolio. It is not an investment adviser.
