U.S. stocks rose in early trading on Thursday on optimism that Congress was progressing toward a fiscal agreement in Washington that would avert a possible recession.
Market participants are focused on discussions in Congress over avoiding big spending cuts and tax hikes, known as the "fiscal cliff," beginning in January. Still, equities may retreat, as they did Tuesday, if the upbeat negotiation environment in Washington deteriorates.

The yield on Italy's 10-year bonds fell to the lowest in two years at an auction, amid relief that immediate risks over Greece had diminished.
"The fact that the bond sales in Europe went well suggest confidence is beginning to reenter some of the peripheral nations and that is a good sign," Cardillo said.

Equity markets may also be supported by data showing the U.S. economy grew faster than first reported between July and September. Separate data showed the number of Americans filing new claims for unemployment benefits dropped for a second week, and a larger-than-expected 3.3 percent advance in third-quarter corporate profits.
