- The index closed at 10,833.78 points on October 30, down 2.73 percent.
- AI-related technology shares led the decline as global concerns about the returns on heavy AI investment weighed on sentiment.
- Shipping, banking, and food and beverage stocks gained, while media and communications shares weakened.
The Shenzhen Component ended Friday's session at 10,833.78 points, down 2.73 percent on October 30. The close was reported by Xinhua. The Shenzhen market had completed its local trading session before the configured European midday reporting window, making this a closing report rather than an intraday update.
Technology shares lead the decline
AI-related companies were at the center of the selling pressure. RTHK, citing Reuters and Xinhua, said the move followed a global sell-off in AI stocks that revived concerns about the returns from large technology investments. The report said the CSI 5G communications gauge fell 6.2 percent, while optical-module producer Eoptolink Technology lost 14 percent. The weakness was part of a broader reassessment of valuations and earnings prospects in AI-linked businesses, rather than an isolated move in the Shenzhen benchmark.
Defensive rotation limits some losses
The decline was broad, but several sectors moved against the market. Xinhua reported gains in shipping, banking, and food and beverage shares, while media and communications stocks fell sharply. RTHK reported that consumer-staple shares rose 2 percent as investors shifted toward less risky areas. The pattern points to a defensive rotation within the mainland market as technology exposure came under renewed pressure.
Turnover rises into the close
Trading activity increased during the sell-off. Xinhua put the combined turnover of stocks covered by the Shanghai Composite and Shenzhen Component at about 1.69 trillion yuan, compared with 1.56 trillion yuan on the previous trading day. RTHK reported turnover of 910.23 billion yuan for the Shenzhen Component. The ChiNext Index, another growth-focused mainland gauge, fell 4.13 percent to 2,413.63 points, underscoring the particularly weak performance of technology and growth shares.
For investors, the session highlights the index's sensitivity to global technology sentiment and to questions about whether AI-related earnings can justify elevated valuations. The decline also shows that stronger performance in selected defensive sectors was not sufficient to offset pressure across the benchmark's growth-oriented constituents.
