INNOSCIENCE (02577) experienced a significant intraday decline of 5.14% as the stock faced selling pressure following recent substantial gains.

The drop comes after the company received listing approval from the Hong Kong Stock Exchange for 374 million H-shares, representing approximately 71% of total share capital, raising market concerns about increased supply pressure from newly circulating shares.

The decline also reflects continued profit-taking activity following a sharp rally earlier in the week, where the stock surged over 20% in a single session and gained another 7% the following day. The previous rally was driven by multiple positive catalysts including NVIDIA's designation of 800V HVDC architecture as the core power solution for next-generation AI factories, with INNOSCIENCE being the sole Chinese supplier on NVIDIA's 800V system list, successful shipments to Google, and a favorable ITC ruling that eliminated trade risks.
