Walmart said it's dealing with what is 'arguably a softer consumer environment' than what it saw earlier in the year
Walmart's stock was tumbling Thursday.
Shares of Walmart slid on Thursday after the retail giant reported quarterly results that suggested its U.S customers are under pressure due to tougher economic conditions.
Walmart reported disappointing U.S. quarterly comparable sales growth, which it said reflected constraints on consumers, as well as a hit to drug prices caused by changes to Medicaid regulations on prescriptions. The company's third-quarter forecast came in below Wall Street's expectations.
