COST vs TJX: How Costco Wholesale and TJX Companies Compare (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: TJX 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. COST and TJX 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 COST and TJX 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. Walnut is not an investment adviser.

Costco Wholesale operates a membership-based warehouse club chain. Members pay an annual fee (currently $65 for basic Gold Star, $130 for Executive) for access to Costco warehouses, where they can buy products at lower markups than traditional retailers. Costco operates approximately 900 warehouses globally, with the largest concentration in the United States plus meaningful presence in Canada, Mexico, the UK, Japan, South Korea, Taiwan, Australia, and other markets.

TJX Companies operates the largest off-price retail business in the world. Brands include T.J. Maxx, Marshalls, HomeGoods, HomeSense, Sierra (off-price outdoor), and TK Maxx internationally. The model is opportunistic buying: TJX merchandise teams buy branded and designer apparel and home goods at deep discounts from manufacturers, brands, and other retailers (overstock, cancellations, end-of-season). These products are then sold at 20-60% below department store prices.

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

• COST drivers: Membership fee growth; International expansion.
• TJX drivers: Consumer trade-down driving traffic; International expansion.

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: Costco's premium valuation embeds high expectations for continued same-store sales growth and margin expansion. For TJX, if consumer pressure eases significantly, the off-price trade-down dynamic moderates.

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 COST if you believe its drivers more; TJX 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 COST and TJX guides.

COST. Costco trades at one of the highest P/E ratios in retail, reflecting the durable membership model, consistent same-store sales growth, and the long runway for international expansion. The premium is also driven by Costco being widely viewed as a quality compounder in retail. The valuation has compressed historically only during severe market drawdowns.

TJX. TJX trades at a premium to traditional department stores and apparel retailers, reflecting the counter-cyclical model durability and consistent execution. The valuation is supported by sustained same-store sales growth even during periods of consumer pressure.

Headline figures (approximate, early 2026): COST shows revenue (ttm) ~$260 billion, operating margin ~3.5% (low, by design; membership fees are the profit lever), net income (ttm) ~$7.5 billion, eps (ttm) ~$17.00; TJX shows revenue (ttm) ~$58 billion, operating margin ~12%, net income (ttm) ~$5 billion, eps (ttm) ~$4.30.

COST and TJX 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.
