REFILE-GLOBAL MARKETS-Stocks gain as U.S. votes, euro steady
* U.S. stocks rise on light buying, Dow up 1 pct
* U.S. election keeps markets subdued
* Euro steady after hitting two-month low before Greece votes
* Gold poised for biggest one-day rise since September
NEW YORK, Nov 6 (Reuters) - World stock markets rose on Tuesday as American voters went to the polls, with the U.S. presidential election keeping trade subdued while the euro held steady despite uncertainty over Greece's next financial aid payment.
Polls indicated President Barack Obama and Republican challenger Mitt Romney remained in a neck-and-neck race, although the Democratic incumbent has a slight edge in several key swing states.
The general view on Wall Street is that a Romney win would favor stocks due to the perception his policies are pro-business, while another Obama term would favor bonds due to views his policies would keep interest rates low.
Analysts downplayed the stock market's advance as traders' betting on Romney pulling out a victory.
"There's been a lot of talk that once the election is decided, no matter how it went, just to have the uncertainty over would be good for the market," said Rick Meckler, president of hedge fund LibertyView Capital Management LLC in Jersey City, New Jersey.
Traders seemed more concerned over how the election results will affect the U.S. government's handling of the "fiscal cliff," the $600 billion worth of automatic tax hikes and spending cuts set to kick in on Jan. 1 unless Congress takes action.
Economists have said the spending cuts and tax hikes could ignite a new recession in the world's biggest economy, while Europe continued to struggle with a prolonged debt crisis that has hurt regional growth.
There is no clear consensus in financial markets on whether Obama or Romney could reach a timely deal with leaders of the opposing party to avoid the fiscal cliff.
"We do know this much," said Peter Kenny, managing director at Knight Capital in Jersey City, New Jersey. "Though the resident in the White House may change, the face of Washington is still going to be one of tremendous gridlock, discord and dysfunction, and markets are going to force Washington to come to terms with the dysfunction."
The winner will also decide who will head the Federal Reserve. There has been speculation Chairman Ben Bernanke, whose term expires in January 2014, might not want to serve another term. Romney has said he will not reappoint Bernanke.
"If Obama wins, we would be certain Ben Bernanke would remain in office as Federal Reserve chairman at least until his normal term expires," said Peter Fertig, a consultant with Quantitative Commodity Research in London.

"Suffice to say if the vote fails, the euro will drop and the dollar will rally, but even if the vote passes, any rally in the euro will be short-lived," said Neil Mellor, currency strategist at Bank of New York Mellon in London.
