US stock-index futures hold modest gains after claims, productivity data


U.S. stock-index futures pointed to a higher open on Wall Street on Thursday, as investors considered economic data ahead of Friday's non-farm payrolls jobs report.

The government on Thursday reported initial jobless claims at 323,000 versus a 335,000 estimate; fourth-quarter productivity rose 1.8 percent, compared to a 1.9 percent estimate.

Costco Wholesale fell in early New York trading after the warehouse-club operator reported a 15 percent drop in quarterly profit, missing analysts' estimates.

The government's jobs report for February will be published on Friday. The Federal Reserve has highlighted unemployment as key in deciding how-and-when ultra-loose monetary policy will be scaled back, so the report will be scrutinized for hints as to future central-bank action.
