The Shanghai Composite slipped 0.2% to around 3,863 while the Shenzhen Component gained 0.9% to 13,040 on Monday, with mainland shares delivering mixed results as investors assessed a batch of economic reports. Data showed that both industrial output and retail sales growth fell short of expectations in August amid soft domestic demand and Beijing’s efforts to curb overcapacity and cut excessive competition. The jobless rate also unexpectedly ticked higher, while new home prices posted their smallest drop in 17 months on the back of government support aimed at easing the prolonged property slump. On the geopolitical front, US and Chinese officials began talks in Madrid on Sunday to address key national security, trade and economic issues. Among notable movers, Victory Giant (-5%) and Cambricon Technologies (-4%) posted steep losses, while Contemporary Amperex (+13.6%) and Sungrow Power (+10.6%) recorded strong gains.
