KEY POINTS
  • Walmart's best growth in comp store sales in a decade comes as the U.S. consumer is showing some of the best signs of strength since the recession.
  • Retail sales jumped in July, but so did the sales performance at retailers as consumers not only went shopping but spent money on travel and dining out.
  • Economists say consumer spending is being helped by the tax bill and also the fact that U.S. job creation remains strong, even as unemployment dipped below 4 percent.

The American consumer is back, and so is Walmart, at least for now.

Walmart stock surged more than 10 percent after the company reported fiscal second-quarter earnings and sales that beat estimates and the best comparable sales growth in a decade. Sales were boosted by groceries, apparel, seasonal merchandise, and its e-commerce sales popped 40 percent.
