Chinese memory-chip stocks posted substantial intraday gains on Wednesday after reports indicated Apple is evaluating DRAM modules from a major domestic producer for devices destined for the Chinese market. Traders and investors responded quickly, bidding up shares of several local foundry and memory-related companies.
In Shanghai trading, Hua Hong Semiconductor Ltd (SS:688347) rallied by more than 14% at its intraday peak. Brite Semiconductor Shanghai Co (SS:688691) - commonly referred to as Canxin - recorded an even larger advance, climbing roughly 20% during the session.
Other listed names linked to China’s memory and chip ecosystem also moved higher: Skyverse Technology (SS:688361) rose about 15%, Kingsemi Co Ltd (SS:688037) gained near 10%, and Shenzhen-listed Wuhan Jingce Electronic Technology (SZ:300567) added approximately 13%.
The surge followed a Financial Times report stating that Apple is testing DRAM chips from state-backed ChangXin Memory Technologies (CXMT) for units sold in China. The report said Apple is also leading lobbying efforts among U.S. technology companies to broaden allowances for the Chinese chipmaker’s products, even though Apple has not committed to commercially adopt CXMT components.
CXMT has grown into the world’s fourth-largest DRAM producer, according to the report, and is expected to expand its slice of global production capacity over the coming years. The test program and the lobbying mentioned in the report have been interpreted by market participants as a potential positive signal for China’s memory supply chain, offering optimism despite ongoing U.S. technology restrictions that apply to some Chinese semiconductor suppliers.
Market moves reflected this optimism: investors rotated into domestic memory and foundry names, pushing intraday gains across several small- and mid-cap chipmakers listed in Shanghai and Shenzhen. The broader implication for the sector rests on whether testing leads to any commercial commitments and on the future interaction between U.S. export rules and procurement choices by major global device makers.
