Wall Street held on to recent gains as data showing China's inflation and industrial production growth cooled in July fanned hopes that the central bank of the world's second-largest economy will act to accelerate the pace of expansion.
In late afternoon trading in New York, the Dow Jones Industrial Average was steady at 13,175.09, the Standard & Poor's 500 Index squeezed out a 0.07 per cent gain and the Nasdaq Composite Index rose 0.20 per cent.
In Europe, the Stoxx 600 Index the day with a 0.4 per cent advance on the previous close.
"The markets have run up quite a bit for quite a while ... and the story is always the same - the hope for stimulus from the ECB, from the Federal Reserve, from the Chinese - from everywhere," Philippe Gijsels, head of research at BNP Paribas Fortis Global Markets, told Reuters.

"The turnaround in home prices feels pretty broad," Celia Chen, a housing economist at Moody's Analytics in West Chester, Pennsylvania, told Bloomberg. "There are still risks that home prices will dip a little more before they start appreciating with any consistency."
There is still plenty of concern about the euro zone's problem children. The yield on Spain's two-year note jumped 15 basis points to 4.02 per cent, while that on the Italian two-year note rose six basis points to 3.26 per cent.
"The market's keeping a close eye on Italy and Spain," David Schnautz, a New York-based fixed-income strategist at Commerzbank, told Bloomberg. "The momentum since the ECB meeting is running out of steam. Spanish bonds are under some pressure. The market gets nervous when it sees double-digit increases in two-year yields."
Highlighting the struggle in Greece with the austerity measures required to secure the next chunk of its international financial lifeline was the latest unemployment data.
