Senior Material's stock surged 42.54% during intraday trading on Tuesday, marking a strong debut on the Hong Kong Stock Exchange.
The significant price increase was driven by extraordinary investor demand during the IPO subscription period. The Hong Kong public offering was oversubscribed by approximately 1,563.16 times, while the international placement was oversubscribed by 14.34 times, reflecting intense market interest in the company's shares.

Additionally, the stock's inclusion in the Stock Connect program on its debut day enhanced liquidity expectations for investors.
