China Major Stock Index Drops Into Bear Market as Tech Sell-off Deepens
Shanghai, Thursday, 22 October 2026.
China’s CSI 300 index fell 20% from its June peak on October 22, 2026, entering a bear market as a sharp technology sell-off and economic headwinds deepened market losses.
Market Benchmark Declines
On Thursday, October 22, 2026, the CSI 300 index confirmed its entry into bear-market territory, defined as a decline of 20% or more from recent highs [1][3]. The benchmark, which tracks 300 of the largest stocks listed in Shanghai and Shenzhen, has now recorded losses for 10 consecutive weeks [1][4]. Data from LSEG indicates the index fell more than 1% during the session and was down 2.6% for the week ending October 22, 2026 [1][2]. This marks the first bear market for the index since the selloff triggered by the COVID-19 pandemic in 2020 [2].
Technology Sector Leads Losses
The technology sector has been disproportionately affected, with AI-linked stocks facing heavy selling pressure amid concerns over valuations and corporate earnings [2][4]. Specific entities saw significant drops, with Z.AI plunging 9.4% and MiniMax falling 6.9% during the session [2][4]. Broader technology gauges reflect this trend, as the SSE Star 50 index lost nearly 40% over the current half-year [2][4]. Similarly, the ChiNext Index, heavily exposed to hardware companies, has fallen 36% in the same period [2]. Major chipmakers have shed around half their value, highlighting the depth of the rout in strategic industries [2][4].
Structural Economic Challenges
Underlying the market volatility are longstanding structural challenges within the world’s second-largest economy [1][3]. Analysts point to excess industrial capacity and overinvestment as key factors pressuring corporate margins [1][5]. The property sector continues to drag on growth, contributing to the slowest expansion in over three years recorded in the second quarter of 2026 [1]. Intense competition has squeezed profit growth, even in sectors where Chinese companies remain globally competitive, such as electric-vehicle batteries [1][2].
Investor Confidence and Outlook
Market dynamics are further complicated by the behavior of retail investors, who drive approximately 90% of daily trading volume compared to 20%-25% in major markets like New York [1]. Shaun Rein of China Market Research Group noted that individual investors are prone to exiting the market faster during periods of uncertainty [1]. While some strategists predict a strong rebound in Chinese equities in 2027, current sentiment reflects a crisis of confidence rather than purely economic fundamentals [1][5]. Hopes for stimulus have faded, adding to the pressure on policymakers to accelerate financial-sector reforms [2][5].
