China Stock of the Day | Kabutaro & Friends

CXMT<688825>, China's leading DRAM maker, was the Chinese stock most talked about online on August 17, 2026.
Background: A-share benchmarks rose broadly that day (Shanghai Composite up 1.41%, Shenzhen Component up 2.44%, ChiNext up 3.14%, STAR 50 up 4.14%), with the semiconductor and memory-chip sector surging across the board. CXMT extended gains into the close, closing up 12% on the day at a fresh all-time high, and its market capitalization surpassed RMB 4 trillion for the first time. Catalysts included SK Hynix's announcement that it would invest USD 38.4 billion to build a new fab in South Korea to meet growing AI-driven demand for memory chips, Morgan Stanley and JPMorgan forecasts that the memory-chip supply shortage would persist for another two years, and a Bernstein report projecting a roughly 17% quarter-on-quarter rise in Q3 DRAM contract prices. CXMT's rally lifted the broader sector, with Tongfu Microelectronics and Youyan New Materials hitting limit-up and AMEC, CFSE, Puran Co., VeriSilicon, and JCET all posting sharp gains; the sector-wide semiconductor index climbed over 5%, and CXMT's role in driving the day's broader market rally drew heavy online discussion.
