Stock index futures were little changed on Thursday as investors looked ahead to weekly jobless claims data, one last clue about the state of the labor market before Friday's key jobs report.

About 375,000 initial claims are expected in the latest week, a dip of 2,000 from the previous week. The data is due at 8:30 a.m. EST (1330 GMT). The number comes a day ahead of the January non-farm payroll report, which is expected to show 150,000 jobs added in January, a decline from the previous month, which benefited from holiday hiring.

It's not surprising to see a flat day today, considering the run we've had and that no one is willing to take a bet before payrolls, said Rick Fier, vice president at Conifer Securities in New York.

Green Mountain Coffee Roasters Inc surged 21 percent to $65.10 in premarket trading a day after its first-quarter earnings far exceeded expectations.
