Stocks rallied Thursday, but they’ve wandered up and down over the last few weeks. That may continue for a while. Next Friday the Bureau of Economic Analysis will release its report on first-quarter GDP growth, a critical look at the economy that investors pay a lot of attention to. On the same day, the federal government is scheduled to reach its borrowing limit, which could trigger a government shutdown unless Congress agrees to extend it.

OIL PRICES: As markets closed, benchmark U.S. crude shed $1.08 to $49.63 a barrel on the New York Mercantile Exchange. In London on the Intercontinental Exchange Europe, Brent crude, used to price international oils, was down $1.04 to $51.95 a barrel.

OIL SERVICES COMPANY: Schlumberger, the world’s biggest oil field services company, fell after it reported less revenue than analysts had forecast. The company said revenue in China, Russia and the North Sea fell more than it had expected. The stock gave up $1.67, about 2.2 percent, to close at $74.84, and competitor Halliburton shed 63 cents, about 1.3 percent, to close at $47.06.
