Is Costco Stock a Buying Opportunity Before 2026?

Motley Fool’s Stock Advisor published a new top-10 stock pick list and noted that Costco was not among its current recommendations, pitching the list as capable of producing outsized returns; the piece highlights historical wins—$1,000 invested in Netflix on Dec. 17, 2004 would have become $521,982 and the same in Nvidia on Apr. 15, 2005 would have become $1,137,459—and cites a Stock Advisor average return of 981% versus a 194% return for the S&P 500 (returns stated as of Dec. 8, 2025). The article is promotional in nature and discloses that The Motley Fool holds and recommends Costco and that the author has an affiliate relationship and may receive compensation from subscriptions, signaling potential conflicts of interest.

Analysis

Motley Fool’s Stock Advisor published a promoted “top-10” stock list (video published Dec. 8, 2025 using Dec. 6, 2025 prices) and explicitly noted Costco Wholesale (COST) was not among the recommendations, while using historical examples that $1,000 into Netflix on Dec. 17, 2004 would have become $521,982 and $1,000 into Nvidia on Apr. 15, 2005 would have become $1,137,459. The piece cites a Stock Advisor average return of 981% versus 194% for the S&P 500 (returns as of Dec. 8, 2025) to frame outsized potential returns and to market subscriptions. The article discloses that The Motley Fool holds and recommends COST and that the author has an affiliate relationship and may receive compensation from subscriptions, creating a clear promotional and potential conflict-of-interest dynamic for readers to weigh. Sentiment and market-impact signals supplied with the article are mildly positive (overall sentiment score 0.25; per-ticker sentiment: COST 0.3, NFLX 0.4, NVDA 0.5), so the coverage is more idea-generation and marketing than a direct fundamental update on Costco’s near-term outlook.

Key Decisions for Investors

• Do not rely solely on the promoted top-10 list; perform independent fundamental analysis on Costco (COST) before increasing, decreasing, or initiating positions given the service omitted COST while the firm discloses it holds and recommends the stock
• Factor the disclosed conflicts of interest and affiliate compensation into position sizing—avoid outsized allocations driven by the publication’s historical anecdotes about NFLX and NVDA and treat the list as marketing-driven idea flow
• Use the top-10 list for idea generation only: validate company-specific metrics (revenue, margins, guidance) and apply disciplined risk controls such as position caps or predefined exit rules before implementing trades
