Costco (COST) is a Top-Ranked Growth Stock: Should You Buy?

Costco has a Zacks Rank of #3 (Hold), a VGM Score of B and a Growth Style Score of A; Zacks forecasts 11.8% year-over-year earnings growth for the current fiscal year. For fiscal 2027, 14 analysts raised estimates in the last 60 days, and the consensus estimate increased by $0.36 to $22.87 per share. Costco's average earnings surprise is +1.2%; the article presents these indicators as supportive of growth-oriented interest, while retaining the Hold rank.

Analysis

This is a weak stock-selection signal, not a fresh fundamental catalyst: estimate revisions and a growth score are backward-looking inputs, while the #3 rank does not indicate a strong near-term earnings-revision advantage. The more durable question is whether Costco can preserve its value proposition as consumers trade down without absorbing too much cost inflation in its deliberately low-price model. If value-seeking traffic strengthens, Costco could gain share from conventional grocers and general-merchandise retailers; if food, labor, or freight costs rise faster than it can pass them through, sales resilience may coexist with margin pressure. Sam’s Club and BJ’s Wholesale Club are relevant competitors, but the article offers no comparative operating data to establish a share shift.

Near term, the promotional framing may support sentiment, but the reported estimate increase is not enough to infer mispricing without valuation and estimate-dispersion data. Over 1–3 months, monthly comparable-sales trends, renewal rates, and gross-margin commentary matter more than style scores. Over 6–18 months, membership economics and the ability to sustain traffic while protecting price perception are the key structural variables. Contrarian read: Costco’s defensive growth profile may be attractive, but that does not make the shares attractive at any multiple; the article supplies no valuation evidence. No standalone trade is justified from this item.

Key Decisions for Investors

• Do not add COST solely on the Zacks growth/VGM scores. Before considering a long, check current valuation versus Costco’s own history and peers, plus the breadth and persistence of forward estimate revisions.
• Keep COST on an event watch for monthly comparable sales, renewal rates, and gross-margin guidance. Strong traffic with stable margins would support the thesis; slowing comps or margin deterioration despite resilient sales would weaken it.
• Avoid treating Costco as an automatic hedge against consumer weakness: trade-down can support traffic, but cost inflation that cannot be passed through could pressure earnings. Reassess if management commentary or reported margins show that tension worsening.
