China Stock Market: CSI 300 Loses 8.5% as Sell-Off Deepens

China's CSI 300 index has fallen 8.5% in October, extending its losing streak to 12 consecutive weeks with a cumulative 15% decline, as investors retreat from technology shares and reassess the country's economic outlook. The sell-off marks one of the toughest stretches for Chinese equities in more than a decade, with sustained weekly losses underscoring persistent weakness in the technology sector and broader sentiment toward the world's second-largest economy. The article was truncated, so no specific catalysts, policy responses, or sector-level figures beyond the index declines were provided. Watch for whether the losing streak breaks, any government stimulus or policy intervention, and further deterioration or stabilization in technology share valuations.
