ACI vs WMT: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 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: ACI 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. ACI and WMT 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 ACI and WMT 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.

Albertsons Companies is a leading US food and drug retailer, running roughly 2,200 supermarkets across the country under about two dozen well-known regional banners, including Albertsons, Safeway, Vons, Jewel-Osco, Shaw's, Acme, and Tom Thumb, along with in-store pharmacies and fuel centers. Its scale makes it one of the largest grocers in the nation, and its business is defensive: food and pharmacy demand is relatively steady through economic cycles. The trade-off is that grocery is a notoriously low-margin, high-competition industry, so Albertsons competes on price, convenience, private label, and loyalty rather than on rapid growth.

Walmart is the largest retailer in the world by revenue and the biggest private employer in the United States. It runs more than 10,000 stores and clubs globally under the Walmart and Sam's Club banners, plus a large and fast-growing e-commerce and digital business. Its core proposition is everyday low prices on groceries and general merchandise, achieved through enormous purchasing scale and a highly efficient supply chain. Walmart makes most of its money from US grocery and general merchandise, but it is increasingly building higher-margin profit engines on top of that traffic: Walmart Connect (a retail advertising business), Walmart+ (a subscription membership), marketplace and fulfillment services for third-party sellers, and financial and health services. Roughly a quarter of revenue comes from outside the US, led by operations in Mexico (Walmex), China, and India (Flipkart). Headquartered in Bentonville, Arkansas, Walmart is a defensive, scale-driven retailer competing with Amazon, Costco, and Target.

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

• ACI drivers: Defensive, steady grocery demand; Digital, loyalty, and retail media.
• WMT drivers: Advertising and high-margin profit pools; Omnichannel scale and grocery dominance.

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 central risk is thin margins and intense competition: Albertsons operates against Walmart, Costco, Kroger, Amazon, and hard discounters like Aldi, which pressure prices and limit profitability in an already low-margin industry. For WMT, walmart's core retail margins are thin, so it depends on enormous volume and on the new high-margin businesses scaling to lift profitability.

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 ACI if you believe its drivers more; WMT 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 ACI and WMT guides.

ACI. These figures are approximate and tied to the asOf date; verify live numbers before acting. Albertsons is valued as a defensive, low-growth grocer, so it typically trades at a modest earnings multiple relative to the broader market, with the dividend and buyback central to total return. The key questions are whether digital, pharmacy, and retail media can lift margins and how well it competes with larger discounters.

WMT. Walmart trades at a historically high P/E for a retailer, reflecting the market's enthusiasm for its higher-margin advertising, marketplace, and membership businesses layered on a defensive grocery base. The thin core margin means earnings growth depends heavily on these new profit pools scaling. Walmart is valued as a quality, recession-resilient compounder rather than a pure low-margin retailer.

Headline figures (approximate, Jul 2026): ACI shows revenue scale One of the largest US grocers, with tens of billions in annual sales across ~2,200 stores, earnings Fiscal 2025 adjusted EPS around $2.18 and adjusted EBITDA near $3.9 billion, margin profile Thin grocery margins, with digital, pharmacy, and retail media the main levers to improve profitability, digital and loyalty Digital sales up about 21% in fiscal 2025; loyalty membership grew past 50 million; WMT shows revenue (ttm) ~$680 billion, operating margin ~4-4.5% (thin, by design), net income (ttm) ~$17-20 billion, eps (ttm) ~$2.30-2.60 adjusted.

ACI and WMT 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 ACI and WMT exposure against your real portfolio. It is not an investment adviser.
