GIGADEVICE is trading at HK$514.50 (+4.66%), driven by a broader Hong Kong memory and semiconductor rally.
- On September 8, 2026, momentum was reinforced as Longsys, a major memory-module maker, began its Hong Kong listing; memory-related products and peers advanced.
- GIGADEVICE repurchased 132,000 A-shares on September 7, providing supportive company news, but no confirmed company-specific announcement directly explains the gain.
