- The Shenzhen Component closed at 10,833.78 points on October 30, down 2.73 percent.
- Technology and communications shares led the decline, while shipping, banking, and food and beverage stocks gained.
- The index fell 15.94 percent over October as investors reassessed the returns on major artificial-intelligence investments.
The Shenzhen Component closed at 10,833.78 points on Friday, October 30, falling 2.73 percent in its final session of the month. The decline extended a technology-led sell-off across mainland Chinese equities and left the index at its lowest level in more than a year, according to Xinhua.
The move followed Thursday's close near 11,138 points and came as selling intensified in media and communications stocks. Xinhua reported that shipping, banking, and food and beverage shares were among the gainers, but those advances were insufficient to offset weakness in technology-related areas. Turnover across the Shanghai Composite and Shenzhen Component was about 1.69 trillion yuan, up from 1.56 trillion yuan in the previous trading session.
AI trade remains under pressure
The broader technology correction was particularly visible in growth-oriented benchmarks. The ChiNext Index fell 4.13 percent to 2,413.63 points, while the STAR Composite Index declined 4.66 percent to 1,421.31 points, according to Xinhua. The pattern points to concentrated pressure on technology and growth stocks rather than a uniform decline across every mainland sector.
Trading Economics attributed the weak technology sentiment to concerns about the returns from heavy artificial-intelligence spending after disappointing signals from major US technology companies. Its market update also said Chinese optical-component and semiconductor shares remained under pressure despite strong quarterly profit growth at some companies. This contrast has made earnings less effective as a near-term support for valuations in the sector.
Sharp monthly loss closes October
The Shenzhen Component lost 15.94 percent during October, according to the same Trading Economics update. The monthly performance underscores how the final-session decline formed part of a broader retreat from the technology trade, rather than an isolated move. The Shanghai Composite fell 1.44 percent to 3,599.02 points on Friday, providing a weaker backdrop for the Shenzhen-listed growth segment.
For investors, the next focus is whether upcoming Chinese purchasing managers' index releases can provide evidence of improving economic momentum. That data may influence the balance between macroeconomic concerns and continued repricing in artificial-intelligence infrastructure stocks. The Shenzhen Component remains a broad index of Shenzhen-listed companies, so its daily direction can reflect both sector concentration and wider risk appetite.
