Draghi speaks: Investors remained focused on the Kansas City Federal Reserve Bank's central bank symposium in Jackson Hole, Wyo., which starts Thursday and runs through Saturday. European Central Bank President Mario Draghi will be a featured speaker on Friday.

On Wednesday, Draghi spoke at a gathering of Nobel Laureates at the Lindau Meeting on Economic Sciences in Germany. Later, he will travel to Jackson Hole.

PMI readings: The eurozone economy kept up its growth momentum in August, according to data from IHS Markit, with a strong rise in manufacturing activity offsetting a slowdown in services.

"The latest PMI readings for the eurozone signal a continuation of the recent strong performance of the currency bloc's economy. This stabilization in the rate of expansion is pleasing, following signs of growth easing in recent months," Andrew Harker, associate director at IHS Markit, said in the report.

The euro edged up to $1.1804, from around $1.1777 ahead of the data and late Tuesday in New York.
