Jobs and economic growth are seen as major themes of Obama\'s speech, scheduled to begin at 9 p.m. (0200 GMT Wednesday). Investors will also listen for any clues on a deal with Republicans to avert automatic spending cuts due to take effect March 1, including the tone of the speech.
The S&P 500 has risen for the past six weeks, putting it up 6.7 percent so far this year, while the Dow is about 1 percent away from its all-time intraday record of 14,198.10, reached in October 2007.
But gains have been harder to come by since the benchmark S&P index hit a five-year high on Feb. 1. The market has had to consolidate strong gains at the year\'s start while investors search for reasons to drive stocks higher.
"We\'re likely to settle in for a period and digest the gains we\'ve had, though there\'s still a bias towards positive momentum," said Eric Teal, chief investment officer at First Citizens Bancshares in Raleigh, North Carolina. "Questions over government spending are the big overhang, and we\'re looking for Obama to inspire some confidence over that tonight."
The White House has signaled Obama will urge investment in infrastructure and clean energy, suggesting companies in those sectors may be volatile in Wednesday\'s session.
"Gun makers could also see a reaction if Obama talks about anything with respect to gun control," said Teal, who helps oversee $5 billion. Shares of Smith & Wesson were flat at $9.13 while Sturm Ruger was up 0.5 percent at $53.96.

Housing shares were among the strongest of the day, led by a 14.4 percent jump in Masco Corp to $20.35 after the home improvement product maker said it expects new home construction to show strong growth in 2013. The PHLX housing sector index rose 4.3 percent.
Avon Products Inc surged 23 percent to $21.25 as the S&P 500\'s top percentage gainer after the cosmetics company reversed sales declines and cut costs.
On the downside, Coca-Cola Co fell 2.7 percent to $37.58 and were the biggest drag on the Dow after reporting revenue that was below estimates, hurt by a weaker-than-expected performance in Europe.
Goodyear Tire & Rubber shares slipped 0.4 percent to $13.86 after it posted a stronger-than-expected quarterly profit but cut its 2013 forecast due to weakness in the European automotive market.
