Marine Le Pen could echo Donald Trump's victory, an economist claims
But the founder of Hong Kong based asset allocation consultancy GaveKal Research says the markets do not want to believe the Front National leader can win in France.
Mr Gave said the momentum behind Ms Le Pen is a slow-moving reaction against finance chiefs in Davos.
And in a boost to Ms Le Pen, he said the number of voters yet to make up their mind, thought to be up to 40 per cent, could be bad for rival Emmanuel Macron leaving the Front National leader the victor.
The economist says he believes only Francois Fillon, who has been blighted by scandal throughout the campaign, could see off Ms Le Pen.
Mr Fillon is currently polling in third place with pollsters largely saying Ms Le Pen will go head-to-head with Mr Macron during the second round on May 7.
Le Pen’s momentum is a slow-moving reaction against the men of Davos – as we have seen with Brexit and Trump – but markets don’t want to believe it
Mr Gave told Bloomberg: “Le Pen’s momentum is a slow-moving reaction against the men of Davos – as we have seen with Brexit and Trump – but markets don’t want to believe it.”
He added at least half of the far-left and half of the centre-right will not vote for Mr Macron and would rather abstain in the second round, believing he is “tainted” by his former association with Francois Hollande’s government.
Mr Macron served as an economy minister in Mr Hollande’s government and took the French establishment by surprise when he launched his presidency bid last year.

Ms Le Pen is expected to make it to the second round of voting
If Ms Le Pen faces leftist Jean-Luc Melenchon in the final round, then the Front National leader could see former supporters of Mr Fillon and Mr Macron rally to her cause.
Using the same model he used to predict Donald Trump’s election success, Mr Galam argued Ms Le Pen could win more than 50 per cent of votes needed in the second round with her core voters heading to the polls and others, who could vote for her rival, finding a reason not to vote at all.

With four leading candidates in the race, Sunday's voting will be followed by a runoff on May 7 between the top two candidates.
The first poll conducted entirely after Thursday's attack suggested Ms Le Pen had gained some ground on Mr Macron.
While he was still seen winning the first round with 24.5 per cent, his score slipped half a percentage point while Ms Le Pen's rose by one to 23 per cent.
Conservative Francois Fillon, a former prime minister, and the far left's Jean-Luc Melenchon were both down half a percentage point on 19 per cent in the Odoxa poll for the newspaper Le Point.
