Wall Street fell heavily on Wednesday, the day after a market rebound, weighed down by another eventful session for the technology sector as well as by political and health uncertainties.

Its flagship index, the Dow Jones Industrial Average, lost 1.92% to 26,763.13 points.

The technology-heavy Nasdaq plunged 3.02% to 10,632.99 points and the broader S&P 500 index lost 2.37% to 3,236.92 points.

“The stock market giants got off to a bad start and there was no buying movement to support the market,” observes Patrick O'Hare of Briefing.com.

The pillars of tech, whose weight on Wall Street is considerable, sank on Wednesday: Apple, Amazon and Netflix dropped more than 4%, Microsoft and Alphabet fell more than 3%.

According to Mr. O'Hare, we can expect a volatile market between now and the US presidential election on November 3, with the New York Stock Exchange alternating between bounces and declines.

Among the values ​​of the day, Tesla fell a little more than 10%, investors appearing disappointed with the announcements of Elon Musk, the boss of the high-end electric vehicle maker, on Tuesday during his "battery day" .

Nike on the other hand soared by 8.76%, after having pleasantly surprised Wall Street on Tuesday after the close by posting during its quarterly results of solid sales of its articles in China and on its electronic platforms.

Johnson & Johnson took 0.16%.

The company on Wednesday became the fourth pharmaceutical group to launch a phase 3 clinical trial in the United States on an experimental vaccine against Covid-19 in a single dose, with 60,000 people on three continents.

On the political side, a budgetary agreement was certainly found Tuesday evening between the American House of Representatives and the White House to avoid the sudden drying up of government funding on September 30.

But dissent remains strong between Democrats and Republicans, and the vote for a new aid package for the US economy does not seem on the agenda.

Meanwhile, the pandemic continues to spread in Europe, where more than 5 million cases have been identified, and in the United States, which has more than 200,000 deaths from Covid-19.

Market players also followed on Wednesday the hearing before US parliamentarians of Federal Reserve boss Jerome Powell, who again defended the Fed's measures to support the US economy in the face of the crisis linked to new coronavirus.

Fed Vice President Randal Quarles spoke to him at the annual meeting of the Institute of International Bankers in New York.
