NEW YORK, Dec 3 (Reuters) - The S&P 500 could rise for a fourth straight day on Monday as U.S. stocks were set to open higher on upbeat factory data from China, but concerns over budget dealings in Washington are expected to keep traders cautious.
China's economy picked up in November even as a broader global recovery remains fragile, with factory activity patchy elsewhere in Asia as demand from the developed world remains weak.
"The good news out of China is encouraging and that's adding to the risk trade this morning," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
Commodities priced in U.S. dollars could rise as the greenback weakens against the euro, possibly lifting stocks in the basic materials and energy sectors.
Markets have focused for weeks on negotiations in Washington over some $600 billion in spending cuts and tax hikes scheduled to kick in next year that could tip the U.S. economy back into recession.
U.S. Treasury Secretary Timothy Geithner pushed Republicans on Sunday to offer specific ideas to cut the deficit and predicted that they would agree to raise tax rates on the rich to obtain a year-end deal to avoid the "fiscal cliff."
"Right now for both sides it's all about staying firm and determined to go to the very end," Cardillo said about the negotiations. "But we all know the stakes are high and (Congress) can't be that stupid as to induce another recession."
Included in the dealings are hikes on dividend taxes, and several U.S. companies have declared special paybacks to shareholders ahead of possibly higher tax burdens.
Dish Network declared Monday a one-time dividend of $1 per share. National Penn Bancshares set a quarterly cash dividend of ten cents per share payable before the end of this year.
S&P 500 futures rose 6 points and were above fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures rose 57 points, and Nasdaq 100 futures added 19 points.
The S&P 500 on Friday closed its fifth positive month in six and is up 8 percent since the end of May.
Adding to the upbeat market tone, Spain formally requested the disbursement more than $50 billion of European funds to recapitalize its crippled banking sector.
Greece said it would spend 10 billion euros ($13 billion) to buy back bonds in a bid to reduce its ballooning debt and unfreeze long-delayed aid, setting a price range above market expectations to ensure sufficient investor interest. The buyback is central to the efforts of Greece's foreign lenders to put the near-bankrupt country's debt back on a sustainable footing.
