Costco posted stronger-than-expected revenue and earnings in its fiscal second quarter, but shares slipped after the report as the company’s post-earnings track record gave investors pause.
Costco had the numbers Wall Street was looking for. It also had a history that made investors think twice about celebrating.
The membership-based warehouse retailer posted fiscal second quarter results that topped analyst expectations across the board today, reporting adjusted earnings per share of $4.58 against a consensus estimate of $4.55 and revenue of $69.6 billion against an estimate of $69.25 billion. The quarterly revenue figure represents a 9.1% increase compared to the same period a year earlier. Net income came in at $2.04 billion, up from $1.79 billion in the prior year quarter.
Despite those numbers, shares edged down roughly 0.3% following the announcement, a reaction that fit a pattern Costco investors know well.
What the Q2 numbers actually showed
The headline figures tell a story of a retailer that continues to grow in multiple directions at once. Comparable sales for the quarter rose 7.4% overall, or 6.7% after adjusting for the effects of gasoline prices and foreign exchange. Within those numbers, U.S. comparable sales climbed 5.9% while Canada posted 10.1% growth and Other International markets grew 13%, a pace that outpaced domestic performance by a wide margin.
Digital sales were the standout figure in the quarterly breakdown, surging 22.6% during the period. That kind of e-commerce growth from a business built entirely around the physical warehouse experience is not something every analyst had priced in, and it speaks to how broadly Costco has expanded its reach without abandoning the in-store model that defines the brand.
February sales added further context, coming in at $21.69 billion, a 9.5% increase from the prior year. Comparable sales for February rose 7.9%, with timing shifts in Lunar New Year and Chinese New Year holidays providing a meaningful positive contribution to international figures.
Costco currently operates 924 warehouses globally, with 634 in the United States and Puerto Rico, 114 in Canada, and 176 across other international markets. The company also runs e-commerce operations in 8 countries.
The golden cross pattern that appeared before earnings
Before the earnings report landed, something notable had already happened in Costco’s stock chart. A technical pattern known as a golden cross appeared today, the first time that signal has shown up in the stock in nearly 3 years.
A golden cross occurs when a stock’s 50-day moving average crosses above its 200-day moving average. Many technical analysts treat this as a signal that a shorter-term rally has matured into a longer-term uptrend. The last time Costco produced this pattern was May 31, 2023. During the period that followed, the stock climbed 92.8% before a reversal signal appeared in August 2025.
The pattern showed up on the same day as earnings following a sharp start to 2026 for the stock. Shares rose 17.2% across January and February combined, the biggest 2-month gain for that period since the first 2 months of 1991. For context, rival BJ’s Wholesale Club posted comparable sales growth of just 1.6% for its most recent quarter, well below its 8-quarter average of 2.4%, which only sharpened the contrast with Costco’s performance.
Historically, the 7 golden crosses in Costco’s chart over the past decade have been mostly positive for investors. During those 7 golden cross periods, the stock rose 4 times by an average of 32.1%. The one period it declined, it fell 10.2%.
Why the earnings beat still wasn’t enough to lift shares
Costco has a well-documented post-earnings pattern that tends to work against even strong results. The stock has declined the day after 6 of the past 8 earnings reports, falling by an average of 3.2% on those occasions. The 2 times it rose following a report, the average gain was just 1.6%.
That history matters to investors who have seen better-than-expected results fail to move the needle before. When a company beats estimates and the stock still drops, the question usually involves expectations rather than performance, specifically whether the beat was large enough to justify a valuation that had already run up significantly.
Analysts had been broadly supportive heading into the report, with some pointing to Costco’s unusual position as a retailer that serves both budget-conscious lower-income shoppers drawn to its pricing and higher-income consumers who simply prefer the value proposition on offer. That dual appeal has helped Costco maintain strong comparable sales growth at a time when many retailers have struggled to hold onto customers in either segment.
The golden cross, the international growth numbers, and the digital sales surge all point in the same direction. Whether today’s stock reaction turns out to be a temporary dip in a longer uptrend is the question Costco investors will be watching closely in the weeks ahead.
