CNBC - Gerard said China’s growing artificial-intelligence capabilities could eventually draw global investors back into its equity market, even before corporate earnings recover.

(UPDATED October 22, 2026 13:21 UTC)
China’s benchmark CSI 300 has entered bear-market territory, falling 20% from its peak after 10 straight weeks of losses. The index, which tracks 300 major stocks in Shanghai and Shenzhen, was down 2.6% for the week. Pressure on shares reflects disappointing earnings, a lack of major fiscal stimulus, and deep economic challenges. China’s economy grew at its slowest pace in more than three years in the second quarter, while companies face shrinking margins and intense competition. Years of overinvestment, a property downturn, and weak consumer demand have added to the strain. Retail investors account for 90% of daily trading in China, and analysts warn they may exit quickly during uncertainty, worsening volatility. Shaun Rein called the sell-off excessive, pointing to resilient exports and signs of property-price recovery. He expects a strong rebound in 2027, while Daniel Gerard says advances in artificial intelligence could eventually attract global investors.
