NEW YORK, Nov 5 (Reuters) - Global stocks fell on Thursday, weighed down by a sharp selloff in semiconductor shares after weak earnings from Qualcomm and concerns that a Democrat-controlled US Congress could slow investment in artificial intelligence infrastructure.
Wall Street's main indexes tumbled, with the Nasdaq on track to confirm a correction from its record closing high. Technology stocks led declines among S&P 500 sectors, while the Philadelphia Semiconductor Index .SOX slumped 9%.
The Dow Jones Industrial Average .DJI fell 2.9%, the S&P 500 .SPX slid 3.6%, and the Nasdaq Composite .IXIC dropped 4.7%.
Qualcomm QCOM.O shares dived 9% after the company's smartphone chip sales missed Wall Street estimates.
"Disappointing earnings and the Dem sweep potentially slowing the AI buildout are pressing sentiment," said Mark Hackett, chief market strategist at Nationwide. "This is a volatile and cyclical group, and when sentiment shifts, the reactions are intense."
Candidates in Tuesday's midterm elections who opposed data centre expansion and campaigned in part on moratoriums on new developments also secured victories in Texas and Georgia, adding to concerns about the outlook for AI-related infrastructure spending.
The MSCI All-World index .MIWD00000PUS fell 2.6%, having surrendered earlier gains, while Europe's STOXX 600 .STOXX lost 0.38%.
"Hedge funds have been aggressively selling for weeks in this area. They were caught short yesterday and were forced to cover but today is a reflection that their bias is still to be short or to de-lever in the semiconductors and neoclouds," Hackett said.
     
OIL REVERSES COURSE
Brent crude futures LCOc1 rose 3.88% to settle at $98.29 a barrel, as investors refocused on uncertainties about the future course of the US war with Iran. After US President Trump's Republican Party suffered heavy losses in the midterm elections on Tuesday, oil prices had tumbled.
Trump acknowledged on Wednesday that the war played a role in Republicans' defeat and his vice president, JD Vance, was even more blunt on X: "The reason we lost is the war." 
Bond prices eased from the day's highs, in line with the rebound in the crude price, leaving yields on benchmark 10-year US notes US10YT=RR down fell 5.93 basis points to 4.835%.
In currencies, the dollar edged into positive territory, gaining against the euro EUR=EBS, which fell 0.04% at $1.1222, and against the pound, which eased 0.1 at $1.346 after  the Bank of England raised interest rates for the first time since 2023 and signalled more may be necessary if the Iran war continues.
     
Spot gold XAU= rose 1.09% to $4,103.83 an ounce.
