The Dow Jones finished up 2.13%, the Nasdaq index, 2.56%, and the broader S&P 500 index, 2.28%.

The session was guided even before the opening by the publication of the monthly report of the Ministry of Labor, according to which the American economy created 223,000 jobs in December, i.e. less than the 256,000 in November but much more than the 200,000 creations expected by economists.

This higher-than-expected figure could have upset operators and fuel fears of continued forced monetary tightening by the US central bank (Fed).

But Wall Street has mainly retained the slowdown in the rise in the average hourly wage, to 0.3% over one month against 0.4% in November.

This is one of the two elements most followed by the Fed, along with price trends, to assess the effectiveness of its fight against inflation.

"It's a win-win for the Fed, with wage increases easing while the job market remains stable," said Peter Essele of Commonwealth Financial Network.

The momentum initiated by the employment report was fueled a little later by another indicator, the ISM index, which showed that activity in services in the United States had contracted in December, for the first time since May 2020.

“We are still in a context where bad (economic) news is welcomed,” explained Nick Reece, of Merk Investments, the signs of a weakening of the American economy which could encourage the Fed to ease off.

For the analyst, the New York market was more sensitive to the ISM than to the employment report, "because it was well below what was expected and below 50" (49.6% ), indicating a contraction in activity.

"That's what drove down (bond) rates and pulled the stock market," he said.

The yield on 10-year US government bonds fell sharply to 3.56%, against 3.71%.

As for the 2-year rate, which is more sensitive to monetary policy expectations, it dropped 20 basis points (0.2 percentage point), a rare drop in the bond market, at 4.25%.

After a sluggish start, all of "tech" got going, driven by a hunt for bargains and the prospect of a more favorable interest rate environment for the significant financing the sector needs to develop.

Apple (+3.68%), Amazon (+3.56%) and graphics card maker Nvidia (+4.16%) were all celebrating.

Even Tesla, after initially falling to its lowest level in almost two and a half years, managed to take the suction (+2.47% to 113.06 dollars).

"After the jobs report, the scenario of a soft landing (of the economy) seems a little more credible than a month ago," said Nick Reece, although some data from the report, from same as the ISM index, urge caution, he said.

Elsewhere on the stock exchange, the airline Southwest Airlines (+4.62% to 35.82 dollars) also took off despite the announcement that the major disruptions which led to the cancellation of more than 16,700 of its flights will cost it between $725 million and $825 million.

This financial impact, which is due to a shortfall but also to additional expenses to solve the logistic problems which had caused the winter storm Elliott will push Southwest into the red in the fourth quarter, warned the company.

The chain of semi-wholesale stores Costco paraded (+ 7.26% to 482.87 dollars) after reporting sales up 5.5% in December compared to the same period last year .

WWE, the American professional wrestling league, listed on the New York Stock Exchange (NYSE) jumped (+ 16.98% to 84.27 dollars) while its former boss, Vince McMahon, took control of the 'company.

Forced to leave last year after accusations of sexual harassment, the one who is still the group's reference shareholder says he wants to participate in negotiations on the new television broadcasting contract but also to lead the search for a potential buyer.
