The New York Stock Exchange ended sharply higher Wednesday, the day after a downturn, in a market optimistic about the recovery of the American economy and supported by several technology stocks, including Facebook and Amazon which reached a new record.

Its flagship index, the Dow Jones Industrial Average took 1.52% to 24.575.90 points

The Nasdaq, with a strong technological coloring, gained 2.08% to 9,375.78 points

The broad S&P 500 index rose 1.67% to 2,971.61 points.

Key values ​​of this index, which represents the 500 largest companies on Wall Street, the giants Facebook (+ 6.04%) and Amazon (+ 1.98%) have reached new heights.

The titles of the two groups, at $ 229.97 and $ 2,497.94 respectively, surpassed their previous records reached earlier in the year.

After starting the week in the green Monday, with encouraging signs regarding the development of a possible vaccine against the coronavirus, Wall Street had fallen on Tuesday before rebounding Wednesday.

"It's a week upside down," sums up Art Hogan of National.

If the market had taken with more caution Tuesday the preliminary results for an experimental vaccine against the virus of the American company of biotechnology Moderna, it is the hope of a rebound of the American economy which seemed to prevail Wednesday.

In addition, the Federal Reserve published during the session the minutes of the last meeting of its monetary committee, in April.

The Fed was particularly worried about the destruction of certain business sectors if they remained shunned by customers, despite the easing of containment measures in many US states.

The pandemic poses many medium- and long-term risks to the economy, members of the Fed's monetary committee also noted.

According to Hogan, the approach of the President of the American Central Bank, Jerome Powell, has been "coherent and systemic" since the beginning of the coronavirus crisis.

"He has repeatedly said that the Fed is not short of ammunition and that it will continue to pursue aggressive monetary policy to offset the effects of the pandemic," said Hogan.

On the bond market, the 10-year rate on the American debt fell, to 0.6785% against 0.6882% Tuesday evening.
