[AI trading shows weakness, European stock markets outperform U.S. stocks in October] October 31st, European stock markets fell slightly on the last trading day of October. However, as artificial intelligence trading showed weakness and promoted capital rotation, European stock markets have recently performed better than the U.S. stock market. The Stoxx Europe 600 index closed down 0.4%, narrowing its gain for the month to about 2%. Technology and mining stocks lagged, with health care and food and beverage stocks leading the gains. Amid a sell-off in global stock markets on Friday, European stocks were once again relatively resilient. Disappointing results from Amazon and Intel once again raised concerns about huge AI spending, sending the Nasdaq 100 index sharply lower. Asian stock markets also fell, with South Korea's Kospi index, considered a bellwether for AI trading sentiment, falling 3.5% as investors reassessed the prospects for technology stocks. UBS's basket of European AI-benefit stocks fell 4.9%. The Stoxx Europe 600 index is set to outperform the S&P 500 in October, which has been weighed down by its heavy weighting in technology stocks. Throughout October, investors turned to more defensive sectors of European markets, while trades that had been strong earlier in the year, such as banks and basic resources, turned into laggards.
