Chinese optical parts maker Zhongji Innolight makes lacklustre trading debut in Hong Kong

Chinese optical parts maker Zhongji Innolight in a lacklustre trading debut, after completing Hong Kong's largest listing in seven years. Its shares finished the day down 2% from the HK$980 offer price, while shares listed in Shenzhen dropped nearly 9%. This is the second-largest offering in Asia this year, behind Chinese chipmaker CXMT Corp's IPO in Shanghai on Monday. Zhongji has already benefited from the AI boom in recent years, with its Q1 profit for this year up nearly four times to 6.3 billion yuan. Jeraldine Yap reports from Hong Kong.
