Costco has lagged the market badly in recent months, but a major analyst upgrade just changed the narrative. Is this the signal that the stock is finally ready to rebound strongly? Here's why experts are getting bullish again...

Financial market analysis from 05/01/2026. Market conditions may have changed since publication.

Have you ever watched a stock you really like take a frustrating dip, wondering if the market is finally giving you a second chance to get in? That’s exactly how I’ve been feeling about Costco lately. After running hot for years, the shares stumbled into the new year, and suddenly, some voices in the investment world are saying it might be time to take another look.

I always find it fascinating how quickly sentiment can shift in the markets. One quarter doesn’t go perfectly, the stock gets punished, and then a fresh perspective comes along that reminds everyone why they loved it in the first place. That’s pretty much the story playing out right now with this retail giant.

A Fresh Vote of Confidence from Wall Street

Let’s start with what got everyone talking this week. A major brokerage firm decided to upgrade their rating on the stock, moving it to the equivalent of a strong buy and slapping on a price target that suggests there’s still decent upside from current levels—around 17% to be more precise.

What caught my attention wasn’t just the upgrade itself (those happen all the time), but the reasoning behind it. The analysts pushed back hard against the recent worries about slowing growth in memberships and same-store sales. Instead, they framed something interesting about the company’s expansion strategy.

Apparently, roughly half of the new warehouses opening in the U.S. aren’t in brand-new markets. They’re what the industry calls “fill-ins”—additional locations in areas where existing stores are already packed to the brim. To me, that’s not a sign of weakness. That’s evidence of insatiable demand. The company literally can’t serve its current customers fast enough, so it’s adding capacity right where the pressure is highest.

This kind of demand is what I’d call a high-class problem—too many loyal customers fighting for space and products.

When you think about it that way, it flips the narrative completely. The market had been interpreting steady growth numbers as potential saturation. But if the company is essentially forced to open more doors just to relieve congestion in proven locations, that tells a very different story about underlying strength.

How the Stock Has Been Performing Lately

To put things in perspective, the shares actually started 2025 on a sour note. While the broader market was charging ahead with double-digit gains, this name was down a few percent. It felt like the magic had worn off temporarily.

Part of that reaction stemmed from the most recent quarterly report. Renewal rates had edged lower—not dramatically, but enough to raise eyebrows. Customers also appeared a bit more selective with their discretionary spending. For a stock that traditionally trades at a premium valuation (the kind usually reserved for fast-growing tech names), any hint of imperfection gets magnified.

I’ve seen this movie before. When a beloved growth story shows even minor cracks, investors can overreact. The multiple compresses quickly because there’s little margin for error built into the price. In my experience, though, these periods often create interesting opportunities if the core business remains solid.

  • Premium valuation leaves little room for disappointment
  • Minor slowdown in key metrics triggers sharp sell-off
  • Long-term competitive advantages often remain intact
  • Pullbacks can reset expectations to more reasonable levels

And in this case, those competitive advantages look very much intact.

Membership Trends: The Real Engine

If there’s one thing that sets this retailer apart, it’s the membership model. People don’t just shop here—they pay an annual fee for the privilege. That creates an incredibly sticky customer base and predictable recurring revenue that most retailers can only dream about.

The recent concern centered on renewal rates drifting slightly lower. But let’s keep this in context. Domestic renewals are still running well above 90%, which is actually better than the long-term average over the past decade. That’s hardly a crisis.

Even more encouraging is what’s happening at the higher tier. Additions to the premium membership level (the one with the bigger annual fee and better rewards) have been growing two to three times faster than overall membership growth. Customers aren’t just renewing—they’re trading up to spend more money with the company each year.

In my view, that’s one of the most underappreciated aspects of the story. It suggests the value proposition remains compelling, especially for heavier users who get the most benefit from the higher-tier card.

When customers voluntarily choose to pay more for greater access, that’s about as strong a vote of confidence as you can get in retail.

Customer Behavior and Spending Patterns

Another positive signal coming from the analysts: shoppers are increasingly trading up to higher-quality, more expensive items. That’s crucial because it shows the membership base isn’t becoming more price-sensitive overall. If anything, the opposite appears to be happening in many categories.

Think about what that means for margins over time. Higher-ticket items often carry better profit dollars, even if the percentage markup is similar. Combine that with the operating leverage from spreading fixed costs over more sales volume, and you have a powerful combination.

Of course, discretionary spending has been a bit softer across retail broadly. People are being more thoughtful about big-ticket purchases. But within the warehouse club format, the essentials business remains rock-solid, and that’s what brings people through the doors repeatedly.

Once they’re inside, the treasure-hunt atmosphere still works its magic. It’s hard to resist those end-cap displays or the latest seasonal items. I’ve fallen for it myself more times than I care to admit.

Technical Perspective: What the Charts Are Saying

Some market commentators have also pointed to improving technical signals. After a rough stretch, certain patterns are emerging that historically have preceded bounces in the shares.

I’m not a pure technician by any means, but I respect when experienced chart readers highlight setups they like. When that aligns with improving fundamentals or sentiment, it definitely makes me pay closer attention.

The stock had been looking pretty ugly for a while—breaking below key moving averages and testing lower levels. But recent price action shows signs of stabilization, and volume patterns have been constructive on up days.

Upcoming Catalysts to Watch

The next few weeks could be particularly interesting. We’ll get monthly sales figures soon, followed by the annual investor meeting. Those events will give management a chance to address the recent concerns directly.

Investors will be listening closely for any commentary on renewal trends and spending patterns. If management can show that the slight softening was transitory—or better yet, that key metrics are starting to reaccelerate—that could act as a meaningful catalyst.

  1. Monthly sales update expected shortly
  2. Annual investor meeting mid-month
  3. Opportunity to reset narrative around membership metrics
  4. Potential for positive surprises on trade-up trends

These aren’t make-or-break moments, but they represent chances to rebuild confidence after the recent wobble.

The Long-Term Story Remains Compelling

Stepping back for a moment, it’s worth remembering why this company has been such a phenomenal long-term performer. The combination of pricing power, customer loyalty, operational efficiency, and international expansion potential is rare in retail.

Perhaps the most interesting aspect is how the business model creates a virtuous cycle. Happy members renew at high rates, which funds competitive pricing and better offerings, which attracts more members, and round and round it goes.

International markets still represent a long runway. Penetration in many countries remains far below U.S. levels, and early results from newer markets have been encouraging.

E-commerce continues to grow rapidly as well, providing another avenue for reaching customers who might not visit warehouses as frequently.

Valuation Considerations in Context

Yes, the stock typically trades at a premium multiple. That’s the price of admission for owning a high-quality compounder with consistent execution. But after the recent pullback, that premium has compressed somewhat.

We’re still not talking about a deep-value situation here, but the risk/reward balance looks better than it did a few months ago. If growth reaccelerates even modestly, the current valuation could prove quite reasonable.

In my experience, the best time to own great companies is often when expectations have been temporarily lowered, not when everything is firing on all cylinders and the stock reflects perfection.

Risks Worth Keeping in Mind

To be balanced about this, there are legitimate risks. Consumer spending could remain pressured if economic conditions soften. Competition in the warehouse club space, while limited, isn’t zero. And valuation will always be a gating factor—if execution slips again, the multiple can contract further.

But these risks feel reasonably well understood at this point. The recent weakness has already priced in a fair amount of caution.

Final Thoughts: Short-Term Pain, Long-Term Potential

I’m probably like a lot of investors when it comes to this name—I get frustrated in the short run when it underperforms, but I’ve never lost faith in the long-term story. The business model is just too powerful, and the customer value proposition too strong.

Recent developments suggest the market may be starting to recognize that again. Whether it’s the analyst community pushing back on overly negative interpretations, improving technical signals, or upcoming opportunities for management to address concerns, there are reasons for cautious optimism.

Will the stock bounce immediately? No one knows for sure. Markets can stay irrational longer than we can stay patient. But for longer-term investors who can tolerate some volatility, the current setup feels considerably more attractive than it did just a few weeks ago.

Sometimes the best opportunities come disguised as temporary disappointments. This might be one of those times.
