Shares in artificial intelligence and technology firms have started to climb following an enormous sell-off on Thursday that wiped trillions of dollars off stock values.

The tech-heavy Nasdaq stock index opened higher following a market rout that began in the US on Thursday before spilling over to Asian and European markets into Friday.

Investors had been selling off tech shares in part due to concerns the Democrat victory in the midterm elections would mean slower artificial intelligence development.

However the latest US employment figures added to a mixed picture for American markets on Friday morning, with an unexpectedly strong 165,000 jobs added to the economy in September.

The Nasdaq Composite opened up 1.23% and continued to gain in early trading, reversing some of its 5.5% fall from Thursday.

The S&P 500 – home of the largest publicly-traded US companies that are not in the technology sector – also opened up slightly, while the Dow Jones Industrial Average opened a little down.

Firms that experienced heavy losses on Thursday also began to bounce back in early trading.

Nvida, which shed hundreds of billions in market value on Thursday after shares slid more than 9%, began Friday trading up more than 6%.

SpaceX and Tesla shares, which were also hammered on Thursday, saw more mixed gains, up more than 7% and nearly 3% respectively.

The market fluctuations come after the sweeping Democrat victory in the midterm elections.

A number of Democrats campaigned for new rules and regulations for artificial intelligence (AI) and data centres, and the party has since won control of both houses of congress as well as key contests in states that have been part of the AI data centre race.

US President Donald Trump on Friday reiterated his supported for what he calls “super intelligence”, saying only “foolish leadership” would “say no to the riches they bring”.

However, there have also been concerns over whether the enormous amounts of money being spent on AI will pay off.

As well as the fallout of the midterms and the plunge in artificial intelligence stocks, US traders will also be digesting the latest jobs figures.

And those numbers were better than expected: US employers added 165,000 new jobs in October, well above the average monthly increase and more than double what analysts had expected.

Overall the unemployment rate, which counts the number of people who are out of work but actively looking for a job, eased slightly to 4.1% from 4.2% in September.

The Bureau of Labor Statistics (BLS) said the unemployment rate has remained in the narrow range of 4.1% to 4.3% since March.

The increase in jobs was led by the professional and business services sector, which added 70,000 jobs. The healthcare sector added 42,000 jobs, and jobs were also added in transportation and warehousing as well as manufacturing.

Neil Birrell, chief investment officer at investment firm Premier Miton, said while the jobs figures may feel like second billing to the market movements they were still important.

“The US economy is running hard which may mean the risks the markets are worrying about at the moment are not such a risk to the real economy as is being feared,” he said.
