Walmart shares fall about 8% after same-store sales growth hits slowest pace since 2020, underscoring ongoing pressure in discount retail

Walmart’s stock dropped sharply on Thursday, falling roughly 8% after the market latched onto a worsening trend in the company’s same-store sales growth. According to the report prompting the selloff, Walmart logged its slowest same-store sales growth since 2020, a announcement investors often interpret as demand softening, intensifying competition, or margin pressure from promotional pricing.

Same-store sales, often tracked as a “comparable” measure, is the sales performance of existing stores over a set period, excluding new locations. For large retailers like Walmart, it is a closely watched barometer of whether shoppers are continuing to choose the chain and whether the company can sustain sales without relying too heavily on new openings. When the pace of same-store sales slows for an extended time, it can weigh on expectations for both revenue momentum and profitability, particularly in discretionary categories that can swing with consumer sentiment.

The magnitude of Walmart’s move, and how it compared with peers, is also part of the story. The same report said Target’s shares held steady, while Costco “eased” rather than falling as much. In practice, that kind of relative performance matters because it frames the market’s view of where the pressure is coming from. If one retailer is hit harder than others, it can imply that investors believe the weaker party faces more immediate traffic, pricing, or mix challenges than its rivals.

For Walmart, the headline figure centers on the “slowest same-store sales growth since 2020” characterization, which is particularly notable because the 2020 reference point is associated with the pandemic-era disruption in retail and consumer behavior. Investors tend to treat that kind of anniversary comparison as a threshold, suggesting the current environment may be approaching a level of sales deterioration that is difficult to ignore.

Target and Costco were included in the report as contrasts. Target’s steadier reaction, as described, suggests the market did not see the same immediate deterioration in its comparable sales trajectory, at least as reflected in the day’s trading. Costco’s milder move points to a similar conclusion: while the broader retail sector may be facing headwinds, the market is not treating all models the same way, and it is distinguishing between retailers that are preserving demand versus those where growth is decelerating more visibly.

Retailers currently operate in a market where customers are balancing needs and budgets, pushing chains to rely on a mix of everyday value, assortment, store operations, and fulfillment speed. A single-day stock reaction, particularly when driven by a summary metric like same-store sales growth, can reflect more than just current demand. It can also incorporate expectations for near-term cost controls, inventory health, and the ability to manage promotions without eroding margins.
