Stock index futures were little changed on Thursday as investors awaited data on the labor market ahead of U.S. President Barack Obama's speech unveiling his plan to stimulate jobs growth.

Weekly U.S. jobless claims are due at 8:30 a.m. EDT (1230 GMT), which investors will look to for signs the recovery is improving. Economists in a Reuters survey forecast a total of 405,000 new filings, compared with 409,000 in the prior week.

After last Friday's dismal U.S. nonfarm payroll data, investors will closely watch Obama's televised speech to Congress at 7 p.m. EDT (2300 GMT). The president is expected to propose tax cuts for middle-class households and businesses and new spending to repair roads, bridges and other infrastructure.

Federal Reserve Chairman Ben Bernanke will deliver a speech on the U.S. economic outlook to the Economic Club of Minnesota at 1:30 p.m. EDT (1730 GMT), but he is unlikely to announce any outline new measures to boost the economy.

We have our unemployment claims numbers this morning, then you have Bernanke later today and the Obama speech tonight, so everybody is going to be positioning in front of these events, said Paul Mendelsohn, chief investment strategist at Windham Financial Services in Charlotte, Vermont.

All (Obama) can really do, as I see it, is create a moral boost to the country. It's a very difficult battle. He's trying to fight a long-term problem with a short-term solution.
