Earlier, we learned that the eurozone flash purchasing managers' index jumped to 53.2 in January, the highest level since June 2011.
Any reading above 50 signals expansion.
This is a preliminary measure. Still, it is up significantly from 52.1 in December, and it is well ahead of the 52.5 expected by economists.
The eurozone's services sub-index improved to a four-month high of 51.9 and the manufacturing sub-index hit a 32-month high of 52.7
"The eurozone's recovery gained further momentum in January," said Markit economist Chris Williamson. "The upturn in the PMI puts the region on course for a 0.4-0.5% expansion of GDP in the first quarter, as a 0.6-0.7% expansion in Germany helps offset a flat-looking picture in France. Elsewhere across the region growth has improved to its fastest since early-2011, meaning the periphery is showing clear signs of starting 2014 on a firm footing."
Germany's Flash PMI number were particularly strong. The composite PMI jumped to a 31-month high of 55.9 in January, with the manufacturing sub-index jumping to a 32-month high of 56.3.
Markets are mixed in Europe. Britain's FTSE 100 is flat. Germany's DAX is down 0.1%, and France's CAC 40 is up 0.1%.
Some of the momentum out of Europe may be hindered by China, were data continue to confirm an economy that is slowing.
