Walmart Reports Strong Q2 Online Sales, But Store Results Disappoint Analysts

Walmart posted the slowest sales in years in its home market of the United States as consumers worried about their finances tightened their wallets.

But the rosy picture on the income front was marred by slower U.S. same-store sales growth.
