NEW YORK — Wall Street headed for a lower opening Tuesday, with investors hesitant ahead of reports expected to show that consumers curtailed their spending amid rising food and energy prices.

The Commerce Department was scheduled to release its April retail sales report at 8:30 a.m. EDT. Economists surveyed by Thomson Financial/IFR estimated, on average, that sales dipped by 0.1 percent last month after growing by 0.2 percent in March. The report is due at 8:30 a.m. EDT.

Retail sales are the clearest indicator of the impact that rising food and energy prices are having on the economy. With consumer spending accounting for more than two-thirds of the nation’s economy, and Wall Street wants to know how much Americans spend at stores, restaurants and car dealerships.

Two other sales reports, the International Shopping Centers-UBS Index and the Johnson Redbook Retail Sales Index, are also scheduled at 7:45 a.m. and 8:55 a.m. EDT, respectively.

Meanwhile, investors got another read on the consumer after Wal-Mart Stores Inc. reported first-quarter profit above Wall Street forecasts. However, the world’s largest retailer, often a barometer of consumer spending in the U.S., forecast that the current quarter will come in below expectations.
