Two Chinese semiconductor companies posted sharp gains on their first day of trading in Hong Kong on Friday, capitalizing on a combined initial public offering that raised approximately $1 billion.

The strong debut highlights renewed investor confidence in the region's chip sector, even as global supply chains remain under scrutiny.

The listings, which include Circuit Fabology Microelectronics, saw shares jump significantly above their offer prices.

This performance adds to a positive week for Asian technology equities, which have been buoyed by robust earnings reports from major U.S. memory chipmakers such as Micron Technology and Qualcomm.

Those results helped alleviate earlier concerns about a potential slowdown in demand for semiconductors.

The successful capital raise comes at a time when Chinese tech firms are increasingly turning to domestic and regional markets for funding.
