Why it's trending
CXMT's stock surged nearly 470% on its first day of trading, making it the most valuable listed company in mainland China despite a global sell-off in tech stocks. The limited float (only 7% of shares tradable) and investor enthusiasm for a homegrown chipmaker drove the rally, drawing widespread attention.
Shares of ChangXin Memory Technologies (CXMT) surged nearly 470% on their debut on the Shanghai Stock Exchange's Star Market, pushing the company's valuation to approximately 3.3 trillion yuan ($487bn), according to the BBC. That makes CXMT the most valuable listed firm in mainland China, surpassing all other publicly traded companies in the country.
The spectacular debut comes despite a sharp sell-off in technology stocks globally this month. Analysts attribute the surge to a severe supply-demand imbalance: only 7% of CXMT's shares are available for trading, as noted by Anna Macdonald of Hargreaves Lansdown. The limited float, combined with strong retail and institutional demand for a domestic chipmaker, propelled the stock upward.
CXMT manufactures dynamic random-access memory (DRAM) chips used in AI data centers, smartphones, PCs, and other devices. Founded in 2016 by Chairman Zhu Yiming and headquartered in Hefei, Anhui Province, the company plans to use most IPO proceeds to expand production and research. Its rise underscores China's push for semiconductor self-reliance amid U.S. export controls. Currently, South Korea's Samsung and SK Hynix, along with U.S.-based Micron, control about 90% of the global DRAM market.
The IPO's strong performance provides a boost to Chinese financial officials, who have been implementing measures to curb a stock market slump that erased over $1.5tn in recent weeks. Attention now turns to whether CXMT can sustain its valuation and compete with established memory-chip giants, as well as how the company's expansion plans will be affected by geopolitical tensions.
