Europe close: Stocks, euro down as traders sell Macron news

At the close, the Stoxx 600 was 0.13% lower at 394.04, the Cac-40 had fallen 0.91% to 5382.95 and the Dax was off by 0.18% at 12,694.55.

"Today's result is a strong victory for President-elect Macron, coming at the upper end what the latest polls had predicted, which nonetheless consistently pointed towards a decent (20pp) gap in the run-up to the second round. It is an important step in ascertaining the policy direction for France, but is not sufficient to gain a complete picture, given the lack of clarity on the outcome of the forthcoming parliamentary elections (11-18 June)," said Francois Cabau and Philippe Gudin at Barclays Research.

The proportion of blank votes cast in the French elections hit a record 9%, twice as many as in 2002, when Jacques Chirac faced off against Jean Marie Le Pen.
