On Wednesday, the Shanghai Composite dipped 0.2% to approximately 3,450, while the Shenzhen Component shed 0.5% to settle at 10,420. These movements followed gains from the previous session as investors opted to secure profits, particularly impacting high-performing technology stocks. Attention is now turning to the upcoming Politburo meeting anticipated later this month, with expectations for the announcement of further stimulus measures designed to counteract the economic pressures from heightened US tariffs. Concurrently, a recent Caixin survey revealed an unexpected return to expansion in China's manufacturing sector for June, indicative of Beijing's intensified efforts to stabilize economic growth. The technology sector experienced significant downturns, highlighted by losses in companies such as Zhongji Innoolight (-4.0%), Suzhou Dongshan (-5.3%), Eoptolink Technology (-3.5%), Victory Giant (-3.1%), and Anhui Greatwall (-3.1%).
