STOCK MARKET REVIEW: hitting a reality check

China’s technology-led equity rally hit a sharp reality check over the past week, as investors reassessed stretched valuations against a still-weak economic backdrop. The clearest reversal came in Shenzhen and its growth-heavy boards: the Shenzhen Component fell from 14,704.27 on August 17 to 13,794.29 on August 24, a 6.2% decline, while the ChiNext Index dropped from 3,740.16 to 3,431.89, down 8.2%. The sell-off suggests enthusiasm around artificial intelligence, semiconductors and robotics remains powerful but increasingly vulnerable when corporate earnings fail to justify rapid share-price gains.

Mainland blue chips held up better but still lost ground. The CSI 300, covering large companies in Shanghai and Shenzhen, fell 3.8% from 4,741.10 to 4,563.13, while the Shanghai Composite declined 2.5% from 3,982.65 to 3,882.01. Wednesday, August 19 was the decisive session: the CSI 300 dropped 2.9%, while the STAR 50 technology index fell 6.9%, as chip and robotics shares were sold heavily amid disappointing corporate results and renewed concern over the broader economy. The downturn came despite a spectacular 460% first-day surge for humanoid robot maker Unitree, illustrating how enthusiasm for strategically important technologies is increasingly concentrated in individual companies rather than lifting the market indiscriminately.

By Monday, selling had spread again across AI computing hardware and biotechnology. ChiNext fell 3.2% in the session and the STAR 50 lost around 3.1%, while money moved toward gold, coal, agriculture and financial stocks. Trading across Shanghai, Shenzhen and Beijing nevertheless exceeded RMB2 trillion, indicating investors were rotating capital rather than abandoning equities altogether.

Hong Kong proved notably more resilient. The Hang Seng finished August 24 at 25,517.33, barely above its 25,453.23 level a week earlier, although Alibaba’s 8.5% fall weighed heavily on Monday. The company priced a record HK$80 billion ($10.2 billion) Hong Kong share placement to fund AI investment. Despite the discount, the deal was almost three times oversubscribed, with strong demand from sovereign wealth and long-only investors—a significant vote of confidence in Chinese technology even as investors become more selective about valuations.

The week therefore exposed a widening distinction between confidence in China’s strategic industries and confidence in the economy as a whole. Beijing continues directing capital toward advanced technology and infrastructure, but weak domestic demand and uneven earnings are making investors less willing to treat policy support alone as sufficient justification for higher valuations. The next test will be whether upcoming earnings can turn the technology story from one driven largely by expectations into one supported by profits.
