US stocks fell and the euro edged lower on Wednesday after optimism faded that European leaders will make substantial progress on resolving the euro zone debt crisis at their summit meeting this weekend.
The Federal Reserve's Beige Book report suggesting the US ecomomic outlook was barely growing in September also sapped sentiment.
The European Union summit on Sunday has been billed as the forum at which the euro zone countries would make significant progress on expanding the EU bailout fund and recapitalizing banks.
But late in the New York session a report on the Wall Street Journal's website undermined hopes for progress at the EU leaders summit this weekend.
Plans to tackle the euro zone debt crisis have stalled with Paris and Berlin at odds over how to increase the firepower of the region's bailout fund, French President Nicolas Sarkozy told French lawmakers.
"At the end of the day, the market is nervous, waiting to see anything substantial coming out of the summit," said Tom Fitzpatrick, chief technical strategist at CitiFX in New York.
"We are getting to a point that there have been so many false promises so they really need to deliver something big."

Technology stocks were the biggest losers on Wall Street. Apple shares fell below USD 400 after the company's revenue and profits came in below estimates for the first time in years on Tuesday as it sold far fewer iPhones than expected.
The US economic outlook grew dimmer in September, leading businesses to be wary of spending and of building up inventories ahead of the holiday sales season, the Federal Reserve said on Wednesday.
"Overall economic activity continued to expand in September, although many districts described the pace of growth as 'modest' or 'slight' and contacts generally noted weaker or less certain outlooks for business conditions," the findings compiled by the regional Fed Bank of Chicago said.
Earlier European shares ended higher, snapping two days of losses, led by bank stocks on hopes the European Union summit on Sunday would come up with a comprehensive plan to resolve the region's debt crisis. The European FTEurofirst 300 index ended up 0.5% at 967.19.
