Wall Street opened in the green Monday after a week marked by the sharp decline in the technology sector and a weekend rich in developments concerning several buyback operations.

Around 2:20 p.m. GMT, its flagship index, the Dow Jones Industrial Average, rose 1.37% to 28,044.90 points.

The Nasdaq, with a strong technological coloring, appreciated by 2.23% to 11,095.62 points.

The extended S&P 500 index gained 1.71% to 3,398.10 points.

Tested by the fall of the big names in tech, the Nasdaq had suffered a weekly drop of 4% last week while the Dow Jones had fallen 1.66%.

Apple, which had a black week on Wall Street but is preparing to present new products and services Tuesday from its California headquarters, gained 2.66%.

Tesla, which had recorded its biggest fall in the stock market last week, took 4.43%.

The many developments of the weekend in terms of mergers and acquisitions also benefited several big names in New York.

Oracle, which confirmed to have made a "proposal" about the application of TikTok light videos, had its action suspended a few minutes after the start of the session.

The title had climbed more than 4% at the opening.

Microsoft, whose plan to buy the Chinese social network was rejected on Sunday, still rose 1.96%.

Owned by the Chinese group ByteDance, the popular application is at the heart of a diplomatic battle between Beijing and Washington, with US President Donald Trump accusing TikTok of spying for the benefit of China without proof and threatening it with a ban in the United States.

In addition, the Californian semiconductor giant Nvidia, which on Sunday confirmed the takeover for some 40 billion dollars of the designer of chips for smartphones Arm Holdings from the Japanese group Softbank, saw its title climb by 7.37%.

For its part, the Californian laboratory Gilead rose 4.14% after the announcement Sunday of its next acquisition for about $ 21 billion of the American biotech Immunomedics, which markets a drug used to treat breast cancer.

The Immunomedics share soared more than 100%.

Market players also seemed optimistic on the front of a vaccine against the new coronavirus with the announcement on Saturday by the British pharmaceutical group AstraZenaca (+ 0.95%) of the resumption of its clinical trials in the United Kingdom and Brazil , which had been interrupted last week.

On the bond market, the 10-year rate on US debt fell to 0.6609% against 0.6658% Friday night.
