On June 5, GigaDevice (03986.HK) declined 4.58% in regular trading, trading at HK$731.0/share, with trading volume of HK$232 million. The drop came as part of a broad-based selloff in Hong Kong-listed storage and memory semiconductor stocks.

On the news front, storage concept stocks in Hong Kong fell sharply across the board on June 5. Leveraged products tracking SK Hynix dropped over 15%, while Samsung-linked leveraged ETFs fell over 13%. Montage Technology declined over 4%. The sector-wide weakness follows a period of extreme gains — GigaDevice had surged over 350% in the past year, with its A-share price briefly exceeding RMB 540 — and mounting concerns over elevated valuations at approximately 55x forward earnings. Additional headwinds include Chairman Zhu Yiming's recent reduction of 6.33 million shares (approximately RMB 2.5 billion in proceeds) during May, and broader market rotation away from high-beta technology names into defensive sectors amid fading policy stimulus expectations.
