Why Costco Stock Dropped Today Despite Strong Sales Numbers

Costco stock saw a noticeable dip in early Thursday trading, sliding about 2.6% shortly after markets opened. The drop followed the company’s release of its November and first-quarter fiscal 2026 sales results — numbers that were far from disappointing. In fact, they were solid across the board. Yet the market reacted with hesitation, leaving many investors wondering what happened.

November and Q1 Sales Show Consistent Growth

Costco reported 8.1% year-over-year growth for the four weeks ending Nov. 30, with net sales reaching $23.6 billion. Looking at a slightly wider window, sales during the 12 weeks leading up to that date totaled $66 billion, an increase of 8.2%.
For the entire first fiscal quarter of 2026, the company generated $72 billion in revenue — again, up 8.2%.

These figures align with, and in some cases surpass, what analysts expected. Market watchers had predicted about 8% Q1 growth, and Costco appears to have exceeded that benchmark.

The Gasoline Effect: Helpful, But Not a Game-Changer

A unique advantage for Costco is the dual nature of its value proposition: affordable groceries and competitive gasoline prices. Customers often capitalize on both in the same trip — either filling up while shopping or stopping to shop after saving at the pump.

When gasoline sales are removed from Costco’s same-store sales (SSS) calculations, the numbers shift slightly:

SSS was 0.5% lower for November
0.1% lower for Q1 overall
No change across the rolling 12-week period

This means gas sales provided a small lift in November, but overall, performance remained largely consistent, with or without fuel included.

So Why the Stock Decline?

According to the analysis from The Motley Fool, there isn’t much fundamental logic behind Thursday’s sell-off. Costco is performing well, continues to hit its sales benchmarks, and maintains strong customer momentum.

However, there is an important perspective to consider:
Costco is rarely a “cheap” stock. With a valuation hovering around 50 times earnings, some investors may simply be reacting to high expectations or locking in profits following a strong run. But according to the commentary in the source material, nothing in the latest report suggests that Costco’s long-term outlook has weakened.

Different Perspectives on Whether Costco Is a Buy

The Motley Fool’s broader investment analysis emphasizes that while Costco is strong, its stock did not make their current list of top 10 investment opportunities. That doesn’t indicate Costco is performing poorly — rather, they believe other companies may offer higher potential returns at this moment.

This contrasts with the sentiment that Costco remains a fundamentally solid long-term investment despite its premium valuation. Both perspectives coexist:

From a fundamentals viewpoint: Costco appears steady and outperforming expectations.
From a value-investing or growth-potential viewpoint: Other stocks may offer more dramatic upside.

Conclusion: A Dip That Raises More Questions Than Concerns

Costco’s stock drop seems more like a market reaction than a reflection of real performance issues. The company continues to show meaningful growth, steady customer loyalty, and strong operational momentum.

For long-term investors, the underlying story remains encouraging: a business that keeps delivering, even in shifting economic conditions.

Sometimes the market’s noise doesn’t match the company’s reality — and Costco’s latest report is a reminder that steady strength can exist even when share prices momentarily slip.
