I'll never forget my first Walmart (WMT) deal as a commercial real estate (CRE) developer.
It was actually a mixed-use project of about 100 acres in Hartsville, South Carolina, that the retail giant agreed to anchor. And, man, did I work for that project.
It took over two years of negotiating with local officials and coordinating the infrastructure to get that thing up and operating… all while traveling back and forth since I didn’t live there.
Yet as frustrating as all that could be, I knew it would be worth it. Having Walmart as a client was a very big deal back then.
It still is today. Because Walmart means practically guaranteed traffic and therefore practically guaranteed rental checks – not just from it but also from fellow tenants that benefit by proximity.
That was such a tried-and-true rule that I even applied it to my efforts for other companies. I would look for the local Walmart, then find available land as nearby as possible. That’s how powerful Sam’s store was.
And still is. Even all these years after I’ve traded my hard hat in for an analyst cap, I haven’t forgotten its appeal. Or its power.
We all know that Walmart is a big-box discount retailer, but the truth is that it’s so much more. It’s a sophisticated ecosystem comprised of physical stores, e-commerce, logistics, advertising, and more.

It’s hard to beat Walmart at that game. It’s one of the best at it I’ve ever seen.
But does that “best” translate into buyable shares? That’s the question we’re exploring today.
Walmart’s 1st moat: economies of scale
Walmart is an enormous international company with massive scale. That’s its most obvious competitive advantage, so let’s start there.
As of July 31, this retail behemoth operated about 11,000 stores and clubs across 19 countries, consisting of:
4,615 Walmart U.S. stores
602 Sam's Club locations
5,783 international retail units.
Apparently, around 90% of the U.S. population lives within 10 miles of a Walmart store or Sam's Club. And, all told, Walmart serves around 280 million customers every week.
That kind of scale gives it near-unbeatable supplier relationships. It’s hard – even impossible – for smaller companies to offer the low prices that Walmart does.
And it benefits from those discounts every bit as much as its customers do. They attract more than enough customers to give it purchasing power with vendors, who would rather cut their own prices to stay in Walmart’s good graces.
Add in how its scale can and does spread operating costs out in ways that boost its bottom line, and you’ve got one mean retail machine.
Walmart’s second moat: logistics and real estate
I might have built for Walmart and even rented to it a time or two. But it actually owns the majority of the real estate it operates out of.
The company has spent decades building out its enormous network of retail, distribution, and transportation centers. And the result is a physical and logistical network that would be exceptionally difficult and expensive for a competitor to replicate.
The land costs alone would be overwhelming, to say nothing about construction expenses or the time and expertise needed to navigate zoning restrictions and red tape.
Yet Walmart doesn’t rest easy on that assurance alone. It’s keeping up with the times by turning its stores into fulfilment centers as well, allowing customers to order online, then either pick it up locally or have it delivered to their doorstep.
That gives it a very important appeal to consumers who, as it turns out, like omnichannel options. Sometimes they want to buy in person. Sometimes they want to skip both the in-store experience and shipping fees by picking their orders up in the parking lot. And sometimes they want the sheer convenience of opening their front doors to scoop up the products in question.
One way or the other, Walmart has what it takes to meet them where they want to be.
Walmart’s 3rd moat: digital transformation
Amazon (AMZN) has definitely changed the shopping game, posing a continuous threat to traditional retailers.
But Walmart has more than held its own. In fact, it brings in more retail-specific revenue than Amazon. A few hundred billion dollars more, in fact.
That’s because, as mentioned above, Walmart has figured out how to change with the times.
These changes include Walmart+, a loyalty program that strengthens customer engagement. This paid membership service, launched in 2020, has grown increasingly more intuitive – especially now that AI shopping assistant “Sparky” is activated.
Sparky makes it easier for members to find what they want when they want it. And according to recent reports, this results in orders that are about 40% larger than they otherwise would be.
Clearly, this bot can bring home the bacon.
Admittedly, larger shopping carts don't automatically translate into proportionately higher profits. But that’s something we’ll discuss further two segments down.
Walmart’s fourth moat: advertising and more
Despite all that impressive retail presence online, offline, and in-between, Walmart isn’t just a shopping center anymore. Not since it launched Walmart Media Group in 2019, which has since been renamed Walmart Connect.
This platform allows companies and brands to pay for advertising space in its digital ecosystem. And considering how many people it reaches online, people are willing to pay top dollar to access them.
As archcompetitor Amazon knows, advertising can generate much higher margins than selling groceries and household products. So not only is this a great way for Walmart to diversify its earnings, it’s also one step further into safeguarding its profits…
And keeping its investors happy.
If the retail giant can maintain its traditional retail appeal while growing its advertising clout, we could see it reclaim its place as the world’s largest company by sales – a position it lost to Amazon earlier this year.
Measuring Walmart's moat – and its value
Here at Wide Moat Research, we love a good competitive moat. However, we also want to see that moat translate into something worth buying and holding.
Similarly, we love a good strong dividend, particularly if it’s been raised 53 years in a row, as Walmart’s has. But that doesn’t mean we shouldn’t look beyond that impressive track record.
For instance, Walmart has generated an average return on equity (ROE) of about 19% over the past five years. And since its current ROE is 22.97%, it does seem to be improving its profitability.
That's encouraging at face value. But it becomes less so when we look at three major retail competitors: Costco (COST), Target (TGT), and Dollar General (DG).
Their respective five-year average ROEs of 28.2%, 31.5%, and 26.9%, respectively, translate into a peer-group average of approximately 28.9%. So considerably higher than Walmart's.
Moreover, Walmart’s five-year average return on invested capital is only about 12%, whereas my preferred threshold is 16%. Don’t get me wrong. It has been improving that metric, but not consistently enough for my liking.
Gross margins, meanwhile, have also remained relatively modest over the past five years. They’ve averaged 24% instead of the 30% – minimum – I like to see.
Yes, this could be seen as a natural product of Walmart's everyday-low-price strategy. But that doesn’t mean I have to overlook the results.
Considering the company’s dominating international presence and global reach, I could still see myself recommending it despite these concerns… if not for its valuation.
Based on my calculations, Walmart is trading at around 42.4x earnings instead of its five-year average closer to 26x. That means shares are showing a 63% premium today.
In which case, we have to look at its earnings per share (EPS). That’s compounded 5.7% annually over the past 20 years, 6.8% over the past 10, and 6.4% over the past five.
None of that’s objectionable in and of itself, especially for a retailer of Walmart’s age and size. But it does become concerning against today’s valuation.
Its current share price implies that Walmart would need to grow operating income at least 15% faster than the company itself recently projected. Put simply, those expectations are just too steep for me.
Roll back the price, Walmart, and I’ll reconsider
I can admire Walmart’s business up and down for its many moats. After working with it directly, I have great respect for what it does and how it does it.
But that doesn’t mean I have to give the same approval to its stock price.
Knowing what to avoid is every bit as important as knowing what to buy. So I have to conclude that Walmart’s shares have climbed too high at 42.4x earnings.

My ultimate rating on this behemoth is Hold for the time being. And I don’t see that changing anytime soon.
