China's AI Index Plummets 40% as Hedge Funds Record Worst Day Since Pandemic

China's AI and semiconductor index dropped 40% on October 27, wiping out about $480 billion in market value, according to Futurism. Earlier, Reuters reported that Chinese technology shares had tumbled as concerns over AI demand and export restrictions pushed investors toward defensive assets.

CNN noted that growing unease about AI firms' financial health had split the S&P 500's market-value and equal-weight indices and triggered a sharp fall in 10-year Treasury yields. Reuters also said that a renewed decline in big-tech stocks, fueled by doubts over AI spending, led major hedge-fund strategies to record their worst day since the pandemic, prompting sector-wide deleveraging.
