COST vs FIVE: How Costco Wholesale and Five Below 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: FIVE 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 FIVE 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 FIVE 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.

Five Below is a discount retailer focused on teens, tweens, and value-seeking parents. The differentiation is the original price-point promise: most products were historically priced at $5 or below, with an expanded $5 Beyond section reaching up to $25 for higher-ticket items (electronics, seasonal furniture, larger toys). The store mix spans candy, party supplies, beauty, tech accessories (phone cases, headphones, chargers), seasonal merchandise, toys, and apparel.

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.
• FIVE drivers: Store expansion runway; Five Beyond 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 FIVE, margin pressure from sourcing costs (tariffs, freight) and from minimum wage increases in store labor markets.

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; FIVE 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 FIVE 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.

FIVE. Five Below's valuation has compressed from peak levels as same-store sales growth has slowed and margins have come under pressure. The store-opening runway and unit economics remain attractive; the question is execution against the unit growth target.

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; FIVE shows revenue (ttm) ~$4.5 billion, operating margin ~8% (compressed from historical levels), net income (ttm) ~$300 million, eps (ttm) ~$5.50.

COST and FIVE 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 COST and FIVE exposure against your real portfolio. It is not an investment adviser.
