The Shanghai Composite closed at 3,658 points on October 22, losing 55 points or 1.5 percent. Optical-module selling and broader concerns about the cost of artificial intelligence investment weighed on Chinese shares, Il Sole 24 Ore Radiocor reported.
The index opened at 3,714 points, up 0.04 percent, before selling pressure intensified. Optical-module shares fell sharply after concerns about U.S. restrictions and supply-chain competition, while robotics and construction machinery stocks were among the stronger groups, Aju Press said.
Why did Shanghai Composite fall?
Technology shares led the decline across Chinese markets. The selling reflected doubts about the returns from heavy AI infrastructure spending and concern that mainland companies could be excluded from overseas supply chains, Xinhua reported.
Rising oil prices after renewed attacks in Saudi Arabia added pressure by increasing concern about energy costs and inflation. The broader technology-led selloff also followed weakness across Asian markets, Il Sole 24 Ore Radiocor said.
Shanghai Composite trading breadth and sectors
Motor manufacturers and construction machinery companies led the gainers. Cinema operators, horse-racing-related shares and media and entertainment companies were among the weakest groups, according to Xinhua.
Nearly 5,000 A-share stocks fell, while total market turnover reached CNY 1.54 trillion, Sina Finance reported. The Shanghai Composite's previous close was 3,713 points, leaving the index 55 points below that level.
