Shares of Walmart Inc WMT.N slumped 7.7%, while those of Target Corp TGT.N and Amazon.com Inc AMZN.O fell over 4% each, with the online retail giant weighing the most on the Nasdaq index .IXIC. "There's a general expectation that Walmart's issues are symptomatic of the entire retail space," said Chuck Lieberman, chief investment officer at Advisor Capital Management. Along with high inflation, a stronger dollar is also expected to weigh on profits of companies with sprawling global operations.
