It was back to business for Wall Street Wednesday.
Stocks declined as a layer of uncertainty was removed with the presidential election complete, leaving the market to return to worrying about the economy.
Barack Obama swept the White House in a decisive victory that, at last count, had him with 349 electoral votes to John McCain's 163, making him the first African-American president in U.S. history. He also soared past McCain in the popular vote.
In his victory speech Tuesday night, Obama said, "change has come to America."
But he was mindful of the tough job that lies ahead.
"Even as we celebrate tonight, we know the challenges that tomorrow will bring are the greatest of our lifetime — two wars, a planet in peril, the worst financial crisis of a century," he told a crowd of more than 125,000. "The road ahead will be long. Our climb will be steep," he said, but added: "I promise you, we as a people will get there."
He also reached across the aisle to McCain's supporters.
"To those Americans whose support I have yet to earn — I may not have won your vote, but I hear your voices, I need your help, and I will be your president, too," he said.

But, as Obama supporters reveled in the candidate's historic victory, Wall Street bowed out of the celebratory glow, turning instead to the grim reality of what lies ahead for the economy.
And traders didn't have to look far to be reminded of the economic challenges facing the 44th president.
The Institute for Supply Management reported its gauge of service-sector activity shrank more than expectedin October, falling to 44.4. from 52.1 in October. Economists had expected a more measured drop to 49.
Private employers cut a larger-than-expected 157,000 jobsin October, payroll firm ADP reported. And, planned layoffs surged to their highest in nearly five years during October, with cuts in the financial and auto sectors leading the charge, according to a report from outplacement firm Challenger, Gray & Christmas.
And, U.S. mortgage-application demand fell to an eight-year low amid a sharp decline in refinancing.
Indeed, Obama's presidential-election prize comes with an albatross—the buckling economy, saddled with the housing meltdown and worst financial crisis in 70 years—that has left Wall Street wondering how Obama will handle it and if he'll be able to jump-start confidence.
