NEW YORK, Nov 2 (Reuters) - World stocks neared a 2-year high on Tuesday while the dollar fell broadly as a second straight day of stronger-than-expected economic news stoked the appetite for riskier assets.
U.S. stocks were also lifted by investors' anticipation of strong Republican gains in Congress halfway through Democratic U.S. President Barack Obama's term.
In campaigns Republicans accused Democrats of stifling business with regulations and failing to extend tax cuts, while Democrats countered that Republicans blocked economic recovery programs.
"I think it is people trying to get in front of what they think will be the election results (Republican gains)," said Rick Meckler, president of investment firm LibertyView Capital Management in New York.
The dollar fell against major currencies, with the U.S. Dollar Index <.DXY> down 0.65 percent. A fall in the greenback makes dollar-denominated commodities cheaper for non-U.S. investors.
Euro zone manufacturing picked up its pace last month, a business survey showed one day after better-than-expected U.S. and Chinese factory data increased optimism about the global economy and revived risk appetite. For details, see [ID:nLDE6A10TX].
"From a global perspective, the growth outlook looks solid and that's feeding some appetite for risk," Omer Esiner, chief market analyst at Commonwealth Foreign Exchange in Washington, said.
The euro traded above $1.40, buoyed by the European economic data, but traders doubted the euro would be able to stay above this level. They cited uncertainty over the scope of the Federal Reserve's expected decision to stimulate U.S. growth via quantitative easing.
A Fed announcement is expected on Wednesday at the end of a two-day policy meeting.
Markets have priced in Fed asset-buying of $100 billion a month for five months in an attempt to bring market rates lower and repair weak growth, which has kept unemployment high.
The size of the program is key. A larger-than-expected program of asset-buying -- which amounts to printing money -- would weigh on the dollar and boost commodity prices, while smaller buying would hit investor risk appetite.
The MSCI world equity index <.MIWD00000PUS> rose 0.74 percent to 319.13, a whisker shy of the two year-high of 319.84 hit on Oct. 25.
On Wall Street, the Dow Jones industrial average <.DJI> was up 69.81 points, or 0.63 percent, at 11,194.43. The Standard & Poor's 500 Index <.SPX> was up 6.90 points, or 0.58 percent, at 1,191.28. The Nasdaq Composite Index <.IXIC> was up 16.73 points, or 0.67 percent, at 2,521.57.
The FTSEurofirst 300 index <.FTEU3> rose 0.45 percent to 1093.95.

Japan's broad-based Topix index fell to its lowest in 19 months on Tuesday as the yen's strength against the dollar hurt shares of exporters. The Topix <.TOPX> ended down 0.02 percent at 803.12, while the benchmark Nikkei <.N225> added 0.1 percent to 9,159.98.
On Monday, a Reuters/Ipsos poll found Republicans are poised to take control of the House, gaining at least 50 seats, but they are unlikely to win a majority in the Senate. (Additional reporting by Angela Moon and Gertrude Chavez-Dreyfuss and Natsuko Waki in London; Editing by Kenneth Barry)
