Economic news drove the markets higher early on in the session Tuesday. The Commerce Department reported construction spending climbed 0.7 percent in January, topping expectations, as both private and public construction hit record levels.

The Institute for Supply Management reported U.S. factory output grew more slowly in February as new orders and hiring intentions eased. The ISM manufacturing index's prices-paid component also fell. Those fearing inflation could see the report as good news, since a slide in demand for industrial goods bodes well for lower prices.

Construction put in place in January increased to a record $1.047 trillion annual rate, compared with an upwardly revised $1.040 trillion rate in December, the Commerce Department said.

A drop in oil prices helped feed buying in stocks, as investors hoped that crude futures would not pass $52 per barrel. A barrel of light crude was quoted at $51.60, down 15 cents, on the New York Mercantile Exchange (search).

"With oil lower, you're seeing the market move broader, moving out of energy stocks and into everything else," said Jay Suskind, head trader at Ryan Beck & Co. "Just across the board, there's a sense the market wants to move higher this spring."

BJ's Wholesale Club Inc. (BJ) said a lease accounting adjustment ate into its quarterly profits, which fell 4.4 percent from a year ago, but the discount retailer still managed to beat Wall Street expectations by 2 cents per share after one-time charges.
