Why Is Walmart (WMT) Stock Price Down 9.15% Today, August 20? Sales Slowdown Reprices Consumer Outlook

Walmart shares slid 9.15% after U.S. comparable-sales growth (2.6%) missed expectations and Q3 adjusted EPS guidance fell below consensus, prompting a reset in consumer-demand and margin assumptions. Slowing traffic and ticket growth, alongside cited fuel-cost headwinds and price rollbacks, increases near-term earnings uncertainty. The move may weigh on broader consumer-discretionary sentiment, but the catalyst is largely company-specific.
