Walmart (NYSE: WMT) shares suffered their steepest single-day decline since May 2022, falling 9% after the retail giant delivered disappointing guidance and weaker-than-expected comparable sales figures.

The drop marks Walmart’s worst one-day performance since May 17, 2022, when shares shed 11%, raising fresh questions about the near-term trajectory of the world’s largest retailer.

Investors were rattled by U.S. comparable sales growth of just 2.6%, falling well short of the 3.5% analysts had anticipated, according to FactSet data shared by CNBC.

Net income also declined, slipping from $7 billion in the prior-year period to $6.3 billion for the second quarter of 2027, adding to the pressure on investor sentiment.

Walmart further warned that it expects to incur more than $2 billion in costs tied to elevated fuel prices, compounding concerns about margin pressure heading into the back half of the year.

The company announced price rollbacks on 11,000 products, a move it said will be funded in part by approximately $2.9 billion in tariff refunds, a one-time financial benefit that will weigh on third-quarter results.

That same strategy is being deployed by rivals including Target, signaling that the broader retail sector is leaning on tariff relief to win back cost-conscious shoppers.

Walmart acknowledged that consumers appear stretched due to high gasoline prices, though it noted that spending remains resilient overall, supported by continued wage growth.

Following the sell-off, the stock sits roughly 7% lower for the year as of August 22, 2026, leaving some investors weighing whether the pullback represents a buying opportunity.

JPMorgan argues that investors should not be deterred by the decline, pointing to Walmart’s positioning to benefit from alternative profit pools and AI automation as long-term tailwinds.

That bullish view aligns with the broader Wall Street consensus, with 40 of the 44 analysts currently covering Walmart carrying a buy or strong buy rating on the stock, according to LSEG data.

Despite the optimism from analysts, the stock is still not considered cheap even after the pullback, meaning investors must weigh long-term potential against a valuation that leaves limited margin for error.
