Zhongji Innolight, an optical transceiver supplier used in AI data centres, begins trading on the Hong Kong Stock Exchange after raising about HK$53.4 billion (around US$6.8 billion) in one of Hong Kong’s largest IPOs in years. Multiple outlets report the company prices its Hong Kong H-share offering at HK$980 per share and that the deal is among the biggest listings in the city since Alibaba’s 2019 IPO. Ahead of the debut, demand from investors—particularly retail—shows strong interest, with one report citing a retail tranche that is multiple times oversubscribed.

On its trading debut day, the stock weakens. Reports describe the share price moving lower shortly after opening and ending the session down around 2% overall, with earlier intraday declines reported as steeper. One source also notes that the company’s Shenzhen-listed shares fall by a larger percentage, extending declines from a June peak. Several outlets link the declines to a broader, global shift in sentiment toward AI-related equities, which affects investor appetite after large AI-linked market rallies.
