European shares eased on October 30 as technology stocks came under pressure from renewed concerns over AI investment returns, even though the benchmark index remained on track for a monthly gain. The pan-European STOXX 600 index fell 0.25 percent to 647.49 by 0809 GMT, according to Reuters.
Technology stocks led the declines, with the sector index down 2 percent, after earnings from Amazon and Intel reignited investor concerns about the sustainability of heavy AI-related spending. The selling followed Alphabet’s 12.6 percent slide on Thursday, a $500 billion washout that had already bruised the sector.
Earnings provide some offset
Strong corporate earnings limited the damage. BP rose 1.1 percent after posting third-quarter net income ahead of expectations, while German sportswear maker Puma jumped 4 percent after its quarterly earnings, according to Reuters.
Political uncertainty in France also weighed on sentiment during the month, as the country faces mounting pressure from rising living costs and elevated government debt. Investors also awaited third-quarter euro zone GDP figures later in the day.
A monthly gain survives the week
Despite Friday’s fall, the STOXX 600 was set to post both weekly and monthly gains thanks to strong corporate earnings, Reuters reported. That resilience underlines how uneven the market reaction has been: companies beating forecasts have been rewarded, while those whose spending outpaces returns have been punished.
The question for the coming week is whether the AI spending debate broadens into a wider risk-off move, or whether earnings from other sectors steady the market. For now, traders are demanding clearer signs that AI investment generates returns rather than simply expanding costs.
European investors will look to the next round of earnings and economic data for a clearer direction. A market that can hold a monthly gain despite a sharp technology selloff is not yet in retreat, but the breadth of the decline will determine whether Friday’s fall was a pause or the start of a deeper correction.
Analysts will also watch whether selling spreads from technology into banks, industrials and consumer stocks, which would signal a broader loss of confidence rather than a sector-specific repricing.
