CVS vs UNH: How CVS Health and UnitedHealth Group Compare (2026)

Same yardstick, side by side (as of July 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: CVS 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. CVS and UNH 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 CVS and UNH 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.

CVS Health runs three reporting segments. Health Care Benefits is the Aetna insurance business, which earns premiums from roughly 26 million medical members and profits when claims (the medical benefit ratio) stay below what it collects. Health Services is built around the Caremark pharmacy benefit manager, which negotiates drug prices and manages pharmacy claims for health plans and employers and generated over $48 billion of revenue in Q1 2026. Pharmacy and Consumer Wellness is the familiar retail footprint of CVS drugstores, which makes money filling prescriptions and selling front-of-store health and consumer goods, with same-store prescription volumes up nearly 7% in Q1 2026.

UnitedHealth Group is the largest US health insurer and one of the largest healthcare companies in the world. It runs through two main engines. UnitedHealthcare is the insurance arm, providing employer, individual, Medicare Advantage, and Medicaid health plans to tens of millions of members. Optum is the faster-growing health-services arm: Optum Health (physician groups and care delivery, including value-based care), Optum Insight (healthcare data, analytics, and technology), and Optum Rx (one of the largest pharmacy benefit managers in the country). The combination lets UnitedHealth manage both the financing and the delivery of care, capturing margin across the system and using vast claims data to manage costs. Headquartered in Minnetonka, Minnesota, UnitedHealth is a Dow component and one of the largest companies in the S&P 500 by revenue. Its scale, vertical integration, and Medicare Advantage leadership define its competitive position.

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

• CVS drivers: Integrated model under one roof; Turnaround and improving Aetna margins.
• UNH drivers: Optum growth engine; Medicare Advantage scale.

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 clearest risk is the medical-cost trend at Aetna: if claims reaccelerate, especially in Medicare Advantage, earnings can fall faster than premiums can be re-priced, which is what drove the 2023 to 2024 decline. For UNH, unitedHealth faces a difficult medical-cost environment: rising utilization (especially in Medicare Advantage) can spike the medical loss ratio and compress margins, as the company has experienced.

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 CVS if you believe its drivers more; UNH 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 CVS and UNH guides.

CVS. CVS trades at a low forward earnings multiple versus the broad market, which reflects lingering caution after the 2023 to 2024 Aetna downturn rather than current results. The value angle rests on whether improving margins and ~$400 billion of revenue can support the raised guidance. Figures are approximate and tied to the asOf date; verify live quotes and the latest filings before acting.

UNH. UnitedHealth's revenue is enormous but its insurance margins are thin by design, so earnings hinge on the medical loss ratio and Optum's higher-margin growth. The valuation reflects scale and integration but has been pressured by cost inflation, regulatory uncertainty, and reputational headwinds. The market weighs Optum's durable growth against insurance-cycle and political risk.

Headline figures (approximate, 2026-06-27): CVS shows revenue (annual run-rate) ~$400 billion; FY2026 guidance at least ~$405 billion, adjusted eps (fy2026 guidance) ~$7.30 to $7.50 (Q1 2026 was ~$2.57), aetna medical benefit ratio (q1 2026) ~84.6%, improved from ~87.3% a year earlier, dividend yield ~2.5% (~$2.66 annual, ~$0.665 quarterly); UNH shows revenue (ttm) ~$400 billion, operating margin ~6-8%, net income (ttm) ~$15-22 billion (sensitive to medical costs), medical loss ratio ~85-89%.

CVS and UNH 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.
