GigaDevice shares slide 5%, following rival CXMT’s blockbuster market debut

GigaDevice Semiconductor shares fell 5% on July 27, 2026. This decline followed the successful trading debut of domestic rival Changxin Memory Technologies (CXMT).

CXMT’s stock surge signaled high investor interest in China’s domestic memory chip sector. The debut increased competitive pressure on GigaDevice within the DRAM market. Capital shifted toward the new listing, causing share price drops across multiple Chinese memory and storage companies.
