Chinese equities slid closer to bear-market territory on Thursday, October 22, 2026, as a global sell-off in technology shares, lacklustre domestic consumption, and fading expectations for stronger government stimulus weighed on investor sentiment.

The CSI 300 Index, which tracks major stocks listed in Shanghai and Shenzhen, fell as much as 1.6%, extending its losses from the June 2026 peak to roughly 20% — the threshold commonly used to define a technical bear market. According to Bloomberg data, the decline has erased about $2.4 trillion in Chinese stock market value since equities peaked in May 2026. The 20% marker is widely watched because it traditionally signals that a downturn has moved beyond a routine pullback, and the scale of value erased offers a measure of how far sentiment toward Chinese assets has cooled since May.

Reversal of the AI-Fuelled Rally

The sell-off marks a sharp reversal of the rally that began in late 2024, when government support and growing optimism about Chinese artificial intelligence companies lifted valuations across the market. Investors are now questioning whether heavy spending on AI infrastructure and technology will translate into sustainable earnings, particularly as concerns over the global AI trade intensify. That tension explains much of the current weakness: the AI optimism that drew capital into Chinese equities over the past two years is now the same source of doubt weighing on them.

Hopes for a stronger economic recovery have also faded. Although China's economy grew faster expected in the third quarter, resilient exports have offset subdued domestic consumption, while Beijing's targeted support measures have fallen short of expectations for a broader fiscal stimulus package. The gap between solid headline growth and soft domestic demand is why investors have continued to look to Beijing for wider fiscal backing rather than targeted steps.

Technology Shares Lead the Declines

Hong Kong's Hang Seng Tech Index fell as much as 5.3% on October 22, 2026, while a gauge of major Chinese companies listed in the city dropped as much as 3.5%. Alibaba and other technology companies came under pressure amid concerns over earnings growth, valuations, and regulatory challenges. The sector's outsized losses reflect where investors' scrutiny is sharpest: these companies were among the most prominent beneficiaries of the AI-driven rally, and it is their earnings and valuations that the market is now testing.

In response, Chinese authorities have stepped up efforts to stabilise the market through state-backed buying aimed at supporting share prices. Analysts, however, have cautioned that these measures may not deliver a sustained recovery without stronger economic support and improved investor confidence. With that in mind, the key markers ahead are whether state-backed buying proves durable, whether policymakers signal a broader fiscal package, and whether corporate earnings begin to ease concerns over growth and valuations.

The downturn also highlights a broader challenge for Beijing: converting recent advances in artificial intelligence and other strategic technologies into profitable, self-sustaining businesses while continuing to rely on capital markets to finance future growth.
