driving factors
On the same day, the market showed a pattern where the main lines of technology and medicine opened low and moved higher. Science Innovation 50 led all major indices by 2.51%. The CRO sector was boosted by a boom in mergers and acquisitions in the global pharmaceutical industry.

The PCB/copper-clad plate direction was catalyzed by a sharp increase in the price of upstream electronic cloth. Citigroup Research reported that in August, the average price of the 1080, 2116, and 7628 series electronic cloth rose 17% to 18% month-on-month, with a cumulative increase of 118% to 165% during the year. Price transmission progressed along the “electronic cloth-copper-clad board-PCB” chain. The direction of innovative drugs was boosted by the acceleration of license-out going overseas. In the first half of 2026, the total amount of Chinese innovative drug license-out overseas was about 99.7 billion US dollars, about double that of the whole of 2024. The turnover of the two markets was about 135.6 billion yuan to 2.66 trillion yuan compared to the previous day. Individual stocks rose and fell less, but the profit effect was only 51%.
