Major indexes opened slightly higher after the government said the economy grew at a slightly faster pace in the spring than first thought.

The US economy expanded at a 1.7 percent annual rate from April through June thanks to slightly stronger consumer spending and exports. That's better than the initial estimate of 1.5

percent. But it's not enough to put a dent in the unemployment rate.

Crude oil dipped back below $96. Hurricane Isaac made landfall Tuesday night, but its heavy winds and rain aren't expected to damage oil production and refinery operations in the Gulf of Mexico.

A handful of companies reported earnings Wednesday. HJ Heinz posted a 14 percent jump in quarterly net income, driven by higher prices and emerging-market sales.

Among other stocks making big moves:

- Joy Global sank 6 percent, the biggest drop in the S&P 500. The supplier of coal mining equipment reported results early Wednesday that missed analysts' estimates and also cut its full-year earnings outlook as demand for coal in the US and China slows. The company's stock lost $3 to $50.08.

- Sealed Air Corp. jumped 8 percent, the S&P 500's biggest gain, after the food packaging company said a former Dow Chemical executive would take over when its current CEO retires.
