* Stocks gain as mixed corporate results temper rally
* U.S. crude oil prices fall more than $1

NEW YORK, Jan 24 (Reuters) - The euro climbed further on Monday on hopes the euro zone is on track to stabilize its debt problems while stocks rose as investors tried to revive a rally that had pushed world equities to August 2008 levels.
Oil prices fell more than $1 a barrel as inventories rose and investors looked to the stock market for direction. Investors also were cautious before the U.S. Federal Reserve's first monetary policy meeting this year on Tuesday and Wednesday.
The euro <EUR=EBS> ran as high as $1.3660 on trading platform EBS, a fresh two-month high against the dollar. It was later trading up 0.31 percent at $1.3657.
The single European currency was also supported by technical momentum after breaking key levels last week, but analysts feared the rally was close to an end as political turmoil in Ireland was a reminder of the uncertainties plaguing the most indebted European countries.

"It's supported in the near-term by optimism over talks on the European rescue fund, but political problems in Ireland and Portugal show there are still lots of factors out there to hurt the currency," he added.
The U.S. dollar slipped 0.4 percent against a basket of major currencies, according to the U.S. Dollar Index <.DXY>. Against the Japanese yen <JPY=>, it was nearly flat at 82.57.
STOCKS MODESTLY HIGHER
Global stocks scored moderate gains as mixed corporate results tempered markets after a multi-week rally. Analysts said, however, that stocks would need positive surprises to keep rising.
"It's going to be tough for us to move higher since we need to digest the long period we had of nice gains with little volatility," said Wayne Kaufman, chief market analyst at John Thomas Financial in New York.
"We'd need really very good earnings numbers and forecasts to continue up, and so far the numbers have been just OK."
