The Nasdaq hit a record high on Monday, with other indexes also rallying, as investors breathed a sigh of relief after Centrist candidate and market favorite Emmanuel Macron won the first round of the French election.
Polls showed pro-EU Macron is expected to beat right-wing rival Marine Le Pen in a deciding vote on May 7, quelling some fears of a breakup of the Eurozone after Britain's shock exit vote last year.
"The markets are in a strong rebound as the expectations of the first round of the French elections results were pleasing," Peter Cardillo, chief market economist at First Standard Financial wrote in a note.
