U.S. stocks began the new year with a broad rally on Wednesday, sparked by a last-minute deal in Washington to avert the "fiscal cliff" of tax hikes and spending cuts that threatened to derail the economy.
In 2013's first trading session, the S&P 500 was on target for its best percentage gain since Nov. 19 and highest close since Oct. 19.
The Dow Jones industrial average gained 229.64 points, or 1.75 percent, to 13,333.78. The Standard & Poor's 500 Index rose 26.53 points, or 1.86 percent, to 1,452.72.
The Nasdaq Composite Index jumped 74.26 points, or 2.46 percent, to 3,093.77.

Spending cuts of $109 billion in military and domestic programs were temporarily delayed, and another fight over raising the U.S. debt limit also looms.
"We got through the fiscal cliff. The next big thing, and probably more contentious thing, is negotiating the debt ceiling and possibly entitlement reform in early 2013," said Jim Russell, senior equity strategist for U.S. Bank Wealth Management in Cincinnati.
Hard choices about budget cuts and the critical need to raise the debt ceiling will confront Congress about the same time in two months "so the fur will be flying," Russell said.
U.S. stocks ended 2012 with the S&P 500 up 13.4 percent for the year, as investors largely shrugged off worries about the
