China Stock of the Day | Kabutaro & Friends

CXMT<688825>, China's leading DRAM maker, was the Chinese stock most talked about online on August 18, 2026.
Background: After hitting a fresh all-time high the previous day, August 17, with a 12% gain that pushed its market cap above RMB 4 trillion for the first time, CXMT reversed course on August 18, 2026, closing down 4.22% at RMB 59.19, with market cap falling back to RMB 3.96 trillion. The stock fell as much as nearly 9% intraday, touching a low of around RMB 56, before paring losses. Its cumulative gain from the RMB 8.66 issue price still stood above 580%. The same day, South Korea's memory chip stocks rallied broadly, with SK Hynix up more than 8% and Samsung Electronics up nearly 5%, while CXMT alone declined, a divergence in East Asian memory-chip stock performance that drew active online discussion. This marked CXMT's third single-day drop of more than 4% since listing, following a 4.08% decline on July 28 and a 4.31% decline on August 6; commentary online also noted that both prior comparable pullbacks were followed by a resumption of the stock's upward trend.
