The New York Stock Exchange, in decline at the opening, has moved forward when the Chinese authorities announced a trade agreement with Washington.

Around 15:15 GMT, its star index, the Dow Jones Industrial Average rose 0.29% to 28,213.04 points after starting in the red.

The Nasdaq, with strong technological color, was up 0.36% to 8,749.35 points, and the broad S & P 500 index of 0.19% to 3,174.68 points.

On the imminent formalization of a compromise between the two parties, Wall Street investors Thursday had won the indexes Nasdaq (+ 0.73%) and S & P 500 (+ 0.86%) to new records and raises the Dow Jones (+ 0.79%).

Several media then said that the US and Chinese negotiators had reached a trade agreement that was only to be approved by the US president.

But China refused to confirm at first that a partial trade deal with Washington was imminent and having postponed several times the time of a press conference on the subject, investors began to doubt and the clues s' showed a slight decrease at the beginning of the session.

The confusion increased when the White House tenant, shortly before the opening of the stock market, tweeted that "the Wall Street Journal article on an agreement with China was completely false, especially their claims on tariffs," without, however, specifying which article it was.

But the hesitation of the brokers quickly dissipated when China officially announced that a preliminary agreement with the United States had been reached.

Beijing also announced that the United States will phase out its punitive tariffs.

These jolts have in any case eclipsed the broad victory of the Conservatives in the British elections, which distances the prospect of a Brexit without agreement and buries that of a Labor government very left.

"Given that consumption represents the lion's share of gross domestic product today, the slowdown in consumer spending is a concern, especially in the fourth quarter when consumption is, in the run-up to the holiday season, important. ", he adds.
