U.S. stock-index futures pointed to a higher Wall Street open on Thursday, as fewer-than-expected Americans filed for unemployment benefits last week.
Initial jobless came in at 331,000, a drop of 20,000 from the prior week. Economists surveyed by Reuters expected 340,000 new claims last week, down from 348,000 in the previous week.
The weekly data comes ahead of Friday's nonfarm payrolls report. After December's disappointing reading, analysts polled by Reuters forecast 185,000 new jobs were created last month. Another weak report could dent investor sentiment, which has been hurt by the reduction in Federal Reserve stimulus, turmoil in emerging markets and slowing Chinese growth.

"I think the market is expecting a decent (jobs) number, but they're worried with the weather… The question is whether it's as bad as everyone thinks," said Gary Thayer, chief macro strategist at Wells Fargo Advisors.
Other economic data Thursday had the U.S. trade deficit expanding 12 percent to $38.7 billion. The Commerce Department report illustrated a broad-based drop after jumping in November, as imports edged higher on increasing consumer demand.
Another report had fourth-quarter productivity coming in a 3.2 percent, versus expectations it would fall to 2.5 percent from 3.0 percent.
Later Thursday, Fed Governor Daniel Tarullo will testify on financial stability.
Shares of General Motors declined after the car manufacturer reported a fourth-profit that came under estimates.
U.S. indices ended little changed on Wednesday as investors reacted to a mixed bag of economic data. Private employers added 175,000 jobs in January, slightly below estimates of 180,000, while the services sector rebounded after two months of slower growth.
Also on Wednesday, Coca-Cola announced it would purchase a 10 percent minority stake in Green Mountain Coffee Roasters for $1.25 billion. Green Mountain shares surged as much as 55 percent in after-hours trading.
UBS cut its rating on Twitter to "sell" on Thursday after the company's first post-IPO earnings report piqued concerns about growth. Frankfurt-listed Twitter shares tumbled over 17 percent early during the day, after the company said that monthly users rose just 3.8 percent in the fourth quarter quarter-on-quarter.
