(By Balachander) U.S. stocks closed on a mixed note, paring earlier gains, as investors weighed remarks by Federal Reserve Chairman Ben Bernanke on the so-called "fiscal cliff" and the central bank's decision to expand its bond-buying plan.
The S&P 500 Index inched up 0.04 percent to end at 1,428.48. The Dow Jones Industrial Average shed 0.02 percent to finish at 13,245.45. The Nasdaq Composite Index dropped 0.28 percent to close at 3,013.81.
"We cannot offset the full impact of the fiscal cliff - it's just too big," Bernanke told a news conference.
The Fed unveiled a new bond-buying plan worth $45 billion a month of longer-term Treasury securities starting January. This is in addition to $40 billion per month purchase of mortgage-backed securities.
The Committee will continue asset purchases "if the outlook for the labor market does not improve substantially," the Fed's policy-making arm said at the conclusion of a two-day meeting in Washington.
The Fed said the federal funds rate will be appropriate at least as long as the unemployment rate remains above 6.5 percent and if inflation is projected to be no more than 2.5 percent.
Investors also eyed negotiations in Washington over a deal to avert the looming "fiscal cliff". President Barack Obama has pushed for higher taxes on wealthy Americans to address the fiscal cliff of roughly $600 billion in spending cuts and tax increases that could hit economic growth.
On the data front, a government report showed that import prices fell 0.9 percent in November after a 0.5 percent gain in October, sharper than economists expectations of a decline of 0.4 percent. Export prices also dropped 0.7 percent after remaining unchanged in October.
