The CSI300 Index, which tracks China's blue-chip stocks, fell 0.4% to a one-year low by the lunch break. The Shanghai Composite Index declined 0.3%. In contrast, Hong Kong's benchmark Hang Seng Index gained 1.6%, supported by a rebound in technology majors. The CSI300 was down 0.9% for the week and 7.6% for October, putting it on course for its biggest monthly decline since July. Over the past 12 weeks, the index has shed 14%, marking its longest losing streak on record. The Hang Seng, meanwhile, was up 1.1% for the week, Reuters reported.

Shares of Alphabet, Amazon.com and Intel fell in the US market amid concerns over mounting AI-related expenditure and its impact on profitability and cash flows. South Korean memory chipmaker SK Hynix also declined more than 7% on Friday, adding to pressure on regional technology stocks. In mainland China, the technology-focused STAR50 index dropped 1.8%. The CSI 5G Communications Index, which tracks the sector, plunged as much as 6% in early trade.

Hong Kong technology shares rebound Despite the broader weakness in Chinese equities, technology majors listed in Hong Kong staged a recovery, with the sector gaining 1.4%. However, the gauge remained close to its lowest level in two years, indicating that investor confidence in the sector remains fragile. According to Reuters, Kenneth Fong, head of China internet research at UBS, said some internet stocks were increasingly being valued as though elevated AI investment would remain a permanent burden on earnings, with investors assigning limited value to the possibility of normalising cash flows or successful monetisation of AI investments. Fong noted that valuations of around 10-11 times price-to-earnings, after accounting for new AI investments, could present an opportunity as markets potentially underestimate the longer-term earnings benefits of these investments. Consumer stocks, property developers outperform While technology stocks remained under pressure, consumer staples offered some support to mainland markets, rising 1% during the session. Hong Kong-listed mainland property developers also advanced 2.7% as investors rotated toward sectors relatively insulated from the global technology selloff, Reuters reported. The divergence between mainland Chinese equities and Hong Kong-listed technology stocks highlighted uneven investor sentiment, with concerns over AI spending and valuations continuing to weigh on technology shares even as selective sectors attracted buying interest.
