Hong Kong shares began Tuesday’s session with modest gains, as the Hang Seng Index opened 0.46% higher. The positive start proved short-lived, however, with the benchmark later slipping into negative territory as investors remained cautious about technology valuations and heavy spending on artificial intelligence.
Technology sentiment weakens
The Hang Seng eased by around 0.3% during early trading, following overnight losses for technology shares on Wall Street. The Nasdaq Composite had fallen 0.76%, adding to uncertainty ahead of Nvidia’s closely watched quarterly earnings announcement on Wednesday.
The results are expected to provide an important test of whether the rapid growth in AI investment can continue to justify elevated valuations across the global technology sector.
Alibaba sale remains in focus
Hong Kong sentiment was also affected by Alibaba’s HK$80 billion, approximately US$10.2 billion, placement of new shares. The offering was priced at a significant discount and will finance further investment in chips, AI infrastructure and artificial intelligence models.
Alibaba suffered a sharp fall on Monday as investors considered the dilution of existing shareholders and questioned how quickly the company’s growing AI expenditure could produce sustainable returns.
A cautious opening
Mainland Chinese markets also traded slightly lower during the morning, while higher oil prices and renewed tensions involving Iran continued to limit regional risk appetite.
Hong Kong’s opening therefore reflected a market caught between longer-term optimism over Chinese technology and immediate concerns about valuations, financing requirements and geopolitical uncertainty.
