LThe Dow Jones Industrial Average jumped 4.98% or 1,086.2 points to end at 22,878.36 points.
The Nasdaq, with strong technological coloring, soared 5.84% to 6,554.36 points.
The S&P 500 extended index gained 4.96% to 2,467.70 points.
This increase corresponds above all to a technical rebound after a particularly chaotic period on Wall Street: the indices, after their worst week since 2008, had fallen further on Monday and had experienced their worst performance ever recorded on Christmas Eve.
After such a rout, the market “was frankly ready for a rebound,” notes Matt Miskin of Manulife Asset Management.
“It’s crazy to see how investors can be so pessimistic and the next day say to themselves that things are not going so badly,” he adds.
“Basically nothing has changed,” says Karl Haeling of LBBW.
In a market with low volumes this holiday season, this significant trend reversal was fueled by the strength of the energy sector, which benefited from the surge of nearly 9% of the barrel of oil listed in New York .
Another catchy point: Amazon gained 9.45% after saying it had never sent so many items for the holiday season. An encouraging signal for the entire retail sector and American consumption in general.
Some big tech stars were also at the party: Facebook appreciated by 8.16%, Apple by 7.04% and Microsoft by 6.83%.
The mood of the market was also reassured by comments from a White House adviser, Kevin Hassett, who assured that the post of Jerome Powell as president of the American central bank was not threatened in any way.
Press reports had mentioned at the end of last week a possible dismissal of the head of the institution by Donald Trump, a possibility feared by investors already worried about seeing the officials, considered as the most important counterweight, leave one by one. the untimely decisions of the tenant of the White House.
In this renewed appetite for risk, the bond market retreated, with the interest rate on ten-year US debt rising to 2.807% from 2.738% on Monday at the close, and the 30-year interest rate at 3.065%, compared to 2.993%.
The Toronto Stock Exchange was closed on Wednesday, Boxing Day.
