China AI Index Plummets 40% as US AI Stocks Gain Momentum

News. com. au reported on 28 October that China's AI-focused Star 50 index fell about 40% over four months, while U. S. AI shares rose on Wall Street amid renewed investor enthusiasm.

Decrypt noted that mainland Chinese equities have shed roughly $2. 4 trillion in market value since May as confidence in AI profitability waned. Futurism added that the AI and semiconductor index's 40% drop erased about $480 billion, and Reuters observed that Chinese technology stocks tumbled amid demand concerns and export restrictions. Earlier, CNN said investors' worries about AI financing sparked a split between the S&P 500's market-value and equal-weight indices, and Reuters reported that a tech sell-off triggered the worst single-day loss for global hedge-fund strategies since the pandemic.
