European shares ended little changed on Wednesday, as gains in commodity stocks were offset by weaker autos, but investors remained upbeat about prospects for the region's equities following solid economic data.
The pan-European STOXX 600 index ended at 380 points after moving in an out of positive territory throughout the session. UK's FTSE added 0.1 percent and Germany's DAX slipped 0.5 percent.
Euro zone businesses had their best quarter in six years, construction purchasing managers' indexes showed, with individual countries' data also improving, indicating broad-based growth in economies across Europe.
Though major indexes were little changed after the data, it added to an improving picture for investors looking at European equities.
"It's the most positive economic backdrop that we have seen since Mario Draghi's been head of the ECB," said Mike Bell, global market strategist at JP Morgan Asset Management.
"Investors are not fully pricing in that improvement in economic fundamentals, perhaps understandably because of political concerns," he added, noting caution around the French election. "We think that now is a good opportunity to be buying European equities while others are still fearful."
Draghi has been ECB president since November 2011.
In a further sign of growing confidence, Citi upgraded continental European stocks to overweight, predicting that the STOXX 600 index would rise another 8 percent by year-end.
