Three Chinese technology companies headlined new listings in Hong Kong on Thursday with share price jumps despite a general retreat by Hong Kong stocks.

Shares of surgery robot maker, Shenzhen Edge Medical, led the trio with a 30.9 percent surge to hit HK$56.60 per share at the end of the day while general-purpose graphic processing unit maker Shanghai Iluvatar CoreX Semiconductor put on 8.44 percent in gains to end trading at HK$156.80 per share.

Edge Medical and Iluvatar raised HK$1.2 billion and HK$3.68 billion, respectively, through the new share sales.

The third tech company – Zhipu, or officially known as Knowledge Atlas Technology – also jumped 13.17 percent to HK$131.50 per share, marking the first pure-play Chinese developer of AI large language models to trade on the Hong Kong stock exchange. It raised HK$4.35 billion in funds from the IPO.

Despite the strong debuts, the Hong Kong bourse lost steam in the new year.

The benchmark Hang Seng Index closed 1.17 percent lower at 26,149 and the Hang Seng tech index slid 1.05 percent to 5,678.
