On May 21, Novosense Micro (02676) declined 5.17% in regular trading, trading at HK$214.4/share, with trading volume of HK$61.20 million. The pullback came after the stock surged over 12% in the prior session and hit a new post-listing high of HK$235.4, triggering concentrated profit-taking.

The stock had accumulated significant short-term gains driven by multiple bullish catalysts, including Q1 revenue growth of 59.17% year-over-year, the semiconductor price hike wave spreading to power management ICs, and the annual general meeting approving an H-share buyback authorization via special resolution. Following the rapid ascent, technical correction pressure intensified, and accumulated gains prompted investors to lock in profits.

Within the Semiconductors sector, today's performance is mixed. Among individual stocks, SMIC up 4.39%, HUA HONG SEMI up 2.41%, MONTAGE TECH up 7.39%, GIGADEVICE up 0.5%, INNOSCIENCE down 1.81%.
