Cambricon stock: China’s leverage curb puts AI-chip favorite in focus before Shanghai open
China’s stock exchanges will raise the minimum margin requirement for new leveraged trades to 100% from 80% starting Monday. Cambricon Technologies Class A shares closed at 1,424.05 yuan Friday, up 0.6%, ahead of the rule change. Traders are watching for forced selling in high-momentum tech stocks as the new rules take effect. Existing margin contracts remain under previous requirements.
