Costco’s Valuation Dilemma: Strong Fundamentals Clash With Market Skepticism

While major market indices continue their upward trajectory, Costco Wholesale Corporation finds itself in a contrasting position. The wholesale giant’s shares are grappling with significant valuation concerns and bearish technical indicators, creating a puzzling disconnect between its stock performance and underlying business strength.

Operational Excellence Amid Market Doubts

Beneath the surface of stock market skepticism, Costco’s business operations demonstrate remarkable vigor. The company’s most recent sales figures reveal sustained growth momentum, with net sales climbing 8.6% to $21.75 billion during October 2025. Particularly impressive was the 16.6% surge in e-commerce revenue, highlighting the company’s successful digital transformation.

This operational success stems from Costco’s unique business model, anchored by an exceptionally loyal membership base that demonstrates renewal rates exceeding 92% across North American markets. The company’s private-label brand, Kirkland Signature, continues to drive profitability and customer retention through its reputation for quality and value.

The Valuation Conundrum

Market participants are currently questioning Costco’s premium valuation multiple. Despite recent price declines, the stock continues to trade at a price-to-earnings ratio above 50—significantly elevated compared to its historical five-year average of approximately 45. This valuation premium, once readily accepted by investors for Costco’s distinctive business approach, now faces intense scrutiny.

Technical analysis reinforces the cautious sentiment, with both short-term and long-term moving averages generating sell signals. This technical deterioration compounds the fundamental valuation concerns creating headwinds for the stock.

Should investors sell immediately? Or is it worth buying Costco?

Global Footprint Expansion Continues

Costco maintains an aggressive international expansion strategy despite market uncertainties. Construction commenced in November 2025 on the company’s first British location in Gloucestershire, while plans are advancing for a new Canadian outlet in British Columbia scheduled to open in 2027.

The international growth story received further validation from Costco Korea’s performance, where revenue jumped 12.1% to surpass the 7 trillion won milestone for the first time. This achievement propelled Costco Korea ahead of the nation’s second-largest hypermarket chain, demonstrating the brand’s global competitive strength.

December Earnings: A Critical Inflection Point

All attention now turns to December 11th, when Costco will release quarterly results that could determine the stock’s near-term trajectory. Market experts anticipate earnings per share of $4.24 for the reporting period. The upcoming financial disclosure represents a crucial test: will robust operational performance justify the current valuation multiple and silence skeptics, or will disappointing results trigger further downward pressure on the share price?

The fundamental question remains whether Costco’s exceptional business metrics can eventually overcome the current valuation concerns, or if the disconnect between operational strength and market performance will persist in the coming quarters.
