On June 5, Yunyinggu Technology (03310.HK) fell 5.85% in regular trading, trading at HK$32.0 per share, with a trading volume of approximately HK$2.98 million.

The decline is primarily attributed to persistent profit-taking pressure following the company's IPO on May 27, when it listed at a price of HK$20.81 per share. On its debut day, the stock surged as much as 91.73%, reaching a high of HK$39.9, fueled by an extraordinary 3,559.68x oversubscription in its Hong Kong public offering. Since then, early investors have been actively locking in gains, pushing the share price into a sustained correction. Although a brief rebound of over 9% occurred on June 3, the stock remains within its post-listing adjustment range, with selling pressure from early profit-takers still unresolved.

Additionally, market concerns over fundamentals have intensified. The company reported negative net profit and negative operating cash flow for the full year, with relatively low gross margins, amplifying valuation disagreements among investors.

Yunyinggu Technology is a China-based company primarily engaged in the R&D, design, and sale of OLED display driver chips, including AMOLED display driver chips and Micro OLED silicon-based display driver backplane chips. By sales volume, it ranks as the fifth-largest global and largest mainland Chinese supplier of smartphone AMOLED display driver chips.
