NEW YORK (AP) — Wal-Mart Stores Inc. reported a 9 percent increase in third-quarter net income as the world's largest retailer continues to woo back shoppers by reemphasizing it has the lowest prices. But the company is seeing its momentum slow as it grapples with an uncertain global economy.

The Bentonville, Ark.-based discounter issued a fourth-quarter profit outlook that was below analysts' forecast. It also reported that revenue at stores open at least a year, a figure that measures growth in established stores, fell short of Wall Street estimates.

Wal-Mart is considered an economic bellwether because the retailer accounts for nearly 10 percent of nonautomotive retail spending in the U.S. The company's latest results underscore how its low- income shoppers continue to have a hard time stretching their dollars to the next pay day and count on rock-bottom prices.
