On July 16, GigaDevice Semiconductor (03986.HK) fell 5.86% in regular trading, trading at HKD 617.0/share, with turnover of HKD 128 million. The broader semiconductor sector saw widespread declines on the same session.

On the news front, today marks the official IPO subscription day for CXMT (ChangXin Memory Technologies, 688825.SH), China's largest DRAM manufacturer. CXMT's IPO pricing was finalized at RMB 8.66/share on July 14, implying a listing valuation of approximately RMB 580 billion — significantly below the market's prior expectation of over RMB 1 trillion. The massive IPO, targeting approximately RMB 579 billion in proceeds, is the largest on the STAR Market in history, creating a substantial liquidity siphoning effect across the semiconductor sector.

GigaDevice holds a 1.8% pre-IPO stake in CXMT and maintains deep business ties with the company, serving as its exclusive DRAM product distribution partner. While the lower-than-expected CXMT valuation may weigh on GigaDevice's investment gain expectations, within the Semiconductors sector, SMIC fell 3.15%, Hua Hong Grace fell 6.85%, Montage Tech fell 9.18%, Biren Tech fell 2.31%, and Iluvatar CoreX fell 6.97%.
