Stock index futures traded essentially flat after an unexpected surge in jobless claims took the wind out of the market, which had risen higher after Caterpillar easily beat both profit and revenue expectations.
Jobless claims soared 51,000 to 454,000, according to the Labor Department. That's far more than the slight rise to 405,000 expected by economists surveyed by Reuters. Claims from the week before were revised slightly lower to 403,000 from 404,000.
The surprising jump was likely due to the relentless snowfall in various parts of the country, which, among other things, slowed down the processing of claims, the government said. The less volatile four-week moving average of initial claims rose 15,750 to 428,750 last week.
Meanwhile, durable goods fell 2.5 percent, the Commerce Department reported. That was far worse than the 1.5 percent rise expected by economists surveyed by Reuters. When volatile transportation orders were stripped out, durable goods orders rose 0.5 percent, although this was also less than expected.
Futures wobbled earlier as investors weighed concerns over developed countries' finances after Standard & Poor's cut Japan's credit rating, as well as a continued deluge of earnings.

Starbucks reported results after the market closed Wednesday, and will be among stocks to watch Thursday.

Stronger-than expected new-home sales in the U.S. and President Barack Obama's call for lower corporate taxes also boosted the Dow 30, which breached 12,000 for the first time in almost three years during Wednesday's session. The index failed to close above that psychologically important threshold, however.
