But Wall Street shares otherwise began the day with promise, bouncing back after last Friday's rout precipitated by worries over the tech industry's massive artificial intelligence spending. China calls for Mideast dialogue in talks with Iran, Saudi, OmanDemocrats, Trump hold final rallies before midterm electionsBut tech shares came under pressure as the session progressed, with the tech-focused Nasdaq slumping 1.1 per cent. "This is still a market that is on edge," said Joseph Zidle, chief market strategist at Cresset Capital, who described unease about midterm elections as adding to worries about the AI boom."The two of them are actually related," Zidle said of midterms and AI, noting that opposition to data centres has animated many campaigns. AI has been "on the ballot in so many places, both blue and red," Zidle said. "It seems like data centres are part of the kitchen table issues."Pollsters expect Democrats to win back control of the House of Representatives, but view Trump's Republican party as potentially able to maintain a majority in the Senate. The loss of total Republican dominance would push the president into unfamiliar and uncomfortable territory: a lame duck period beset with high inflation at home, the sputtering war against Iran and hostile Democratic investigations into his activities in Washington."Investors are bracing for a fresh round of turbulence ahead of US midterm election fireworks while they assess the extent that companies are burning through cash to keep the AI bonfires burning," said Susannah Streeter, chief investment strategist at Wealth Club.Earnings this week will come from Apple, which reports after the close of trading on Monday, as well as Advanced Micro Devices and software titan Palantir will be closely watched this week. Shares in Apple fell 1.8 per cent.Source: AFP/fsSign up for our newslettersGet our pick of top stories and thought-provoking articles in your inboxSubscribe hereGet the CNA appStay updated with notifications for breaking news and our best storiesDownload hereGet WhatsApp alertsJoin our channel for the top reads for the day on your preferred chat appJoin hereAlso worth readingContent is loading...Expand to read the full storyGet bite-sized news via a newcards interface.
