New York - European equities surged and US stocks hit fresh records on Wednesday in anticipation the European Central Bank will extend its stimulus, and amid optimism about the American economy after the presidential election.

In the US, the Dow Jones Industrial Average surged to a record for the third straight session in the best day for Wall Street equities since the November 8 US election.
The US rally has been sparked by hopes President-elect Donald Trump and the Republican-led Congress will enact policies that fuel stronger growth and loosen regulation in the world's biggest economy.
"Right now people are making bets based on potential and whether that potential becomes real, we're not going to know for another six plus months," said Michael James, managing director of equity trading at Wedbush Securities.
"The path of least resistance right now is higher."

Tokyo-listed SoftBank soared 6.2% to ¥7 387, with investors hailing news the company agreed to invest $50bn in the United States.
Trump announced the deal with much fanfare in the lobby of Trump Tower in New York, alongside SoftBank's flamboyant CEO Masayoshi Son, and said it would create a staggering 50 000 jobs.
