The Shanghai Composite closed at 3,713 points on October 21, 2026, down 22 points or 0.6 percent, Xinhua reported. The decline followed weaker earnings signals from battery maker CATL.
CATL fell 12.0 percent after third-quarter profit rose 14.5 percent year over year, below market expectations, Morningstar reported.
Why did the Shanghai Composite fall?
Corporate earnings concerns weighed on the market, while weak domestic demand added pressure. Xinhua said batteries, energy metals and education stocks were among the biggest decliners, while pork and culture and media shares led gains. CATL's weaker margin and profit outlook intensified selling across the battery supply chain.
