Story HighlightsThe CSI 300 fell 8.5% in October, marking its worst monthly performance since early 2016.
China's technology-focused STAR 50 index has dropped around 40% from its June peak, wiping out approximately $480 billion in market value.
Fresh government support measures have failed to restore investor confidence, with AI concerns and economic weakness continuing to weigh on equities.
China’s stock market is facing one of its toughest periods in more than a decade as investors retreat from technology shares and reassess the country’s economic outlook. The CSI 300 has extended its losing streak to 12 consecutive weeks, falling 15% over the period and recording an 8.5% monthly decline in October. The latest selling has continued into November, despite Beijing announcing fresh measures to stabilise the market. Here are the three key factors driving the China stock market sell-off.

The global retreat from artificial intelligence stocks has become a major drag on Chinese equities. Investors are increasingly questioning whether the massive spending on AI infrastructure, semiconductors and computing capacity will generate sufficient returns.
China’s technology sector has been particularly vulnerable. The STAR 50 index, which tracks major technology companies listed on Shanghai’s STAR Market, has fallen around 40% from its late-June peak, erasing approximately $480 billion in market value.
The pressure intensified in October as selling spread across semiconductor and communications equipment companies. On October 30, the CSI 5G communications index dropped 6.2%, while optical module maker Eoptolink Technology plunged 14%. The STAR 50 also fell 5.5% during the session.
The weakness reflects growing concerns about AI valuations and the profitability of heavy capital expenditure. Investors are reassessing whether the expected growth in AI demand can justify the valuations built into technology stocks earlier this year.
China’s Economic Weakness Adds to Market Pressure
Beyond the technology sell-off, persistent economic challenges are weighing on investor confidence. Weak domestic consumption and continued stress in the property sector have raised questions about the strength of China’s economic recovery.
The property market remains a significant concern, particularly as developers continue to face financial pressure. Recent reports that state-owned developer Zhuhai Huafa Group was seeking extensions on certain bank loans have added to worries about debt-related risks in the sector.
These concerns are creating an uncertain outlook for businesses and investors. Weak domestic demand can limit corporate revenue growth, while property-sector stress threatens to weigh on broader economic activity.
