Hong Kong Tech Stocks Under Pressure as Market Sentiment Cools

Hong Kong's equity market failed to sustain its recent rebound on September 8, with major indices closing in negative territory. The benchmark Hang Seng Index edged down 0.38%, while the technology-heavy Hang Seng Tech Index underperformed significantly, dropping 1.61% to highlight ongoing pressure on the sector.

AI Stocks Lead Market Decline as Zhipu.ai Plunges Over 10%

The most notable selling pressure emerged in artificial intelligence-related stocks. Several AI software companies saw sharp declines during the session:

  • Haiqing Zhiyuan dropped more than 11%
  • Zhipu.ai fell over 10%, making it one of the day's worst performers
  • Weimob Group declined more than 6%
  • MiniMax lost over 5%

This pullback suggests growing investor concern about stretched valuations in the AI space, with some traders taking profits after recent gains.

Optical Communication Shares Join the Retreat

The weakness extended to optical communication stocks. XiZhi Technology-P slid more than 7%, while Lens Technology fell over 4%. Industry leaders Sunny Optical Technology and Zhongji Innolight also retreated, both dropping more than 3%. Market observers attribute the sector's weakness to shifting demand expectations.

New Southbound Trading Inclusion Sparks 31% Rally for Haiguang Xinzheng

Amid the broad market weakness, Haiguang Xinzheng stood out with a remarkable 31% surge. The catalyst came from its inclusion in the Stock Connect program starting September 7, allowing mainland investors direct access to the stock through southbound trading channels.

Market participants note that Stock Connect inclusion typically brings increased attention and liquidity, particularly for smaller-cap names. Haiguang Xinzheng's dramatic rise reflects positive market reception to this structural change.

Outlook: Valuation Concerns Linger for Tech Sector

The tech sector's weakness aligns with global trends as rising interest rates pressure growth stock valuations. Analysts emphasize the importance of matching valuations with fundamental performance, especially in popular sectors like AI where earnings delivery will be crucial for future price action.

Meanwhile, changes to Stock Connect constituents will continue influencing individual stock liquidity. Newly added names may attract increased southbound flows, while removed stocks could face reduced trading activity—a dynamic worth monitoring for Hong Kong market participants.
