Stock market review: two stories for tech

China’s stock markets have told two very different stories this past week. On the mainland, investors have pulled back from many of this year’s hottest technology stocks, especially companies linked to artificial intelligence (AI). In Hong Kong, however, confidence remained much stronger, with internet giants such as Alibaba helping push the market higher. The contrast suggests investors are becoming more selective. Rather than buying anything connected to AI, they are looking more closely at which companies are most likely to turn the technology into long-term profits.

The mainland sell-off was led by Shenzhen, home to many of China’s technology companies. The Shenzhen Component Index closed at 13,448 on August 3, down 4.95% from 14,148 a week earlier. The broader CSI 300 index, which tracks many of China’s biggest listed companies, fell 3.39% to 4,543. By comparison, the Shanghai Composite slipped a more modest 1.26% to 3,809, helped by its larger weighting of banks and state-owned companies, which tend to be less volatile.

The biggest pressure came from technology shares. After months of strong gains, investors took profits as concerns grew that AI-related stocks had risen too quickly. The move was part of a wider global pullback in technology shares rather than a sign that investors had lost confidence in China’s AI ambitions. Beijing continues to treat advanced technology and semiconductor development as strategic priorities, but this week’s trading showed investors are becoming more cautious about how much they are willing to pay for future growth.

Hong Kong painted a different picture. The Hang Seng Index rose 3.18% over the week, and closed on Monday at 26,009, supported by large internet companies. Alibaba jumped after unveiling what it described as its most powerful AI model yet, reinforcing optimism about businesses that already have established cloud computing and digital services operations. Investors appear more comfortable backing companies with proven earnings than manufacturers supplying the AI boom.

Chinese companies listed overseas also had a positive week. The Nasdaq Golden Dragon China Index, which tracks Chinese firms listed in the United States, rose about 6%, helped by gains in major technology stocks. Meanwhile, Hong Kong continued to attract fundraising from mainland firms, although the weak market debut of optical-components maker Zhongji Innolight showed investors remain cautious about highly valued technology companies.

Taken together, this week’s trading does not suggest investors are losing confidence in China’s economy. Instead, it points to a more mature phase of the market. Capital is still flowing into sectors that fit Beijing’s long-term priorities, particularly technology, but investors are becoming much more selective about where they put their money. Next week, attention will turn to whether mainland technology shares stabilise after this correction or whether investors continue shifting towards larger, more established companies in Hong Kong.
