Bloomberg, the Financial Times and CNBC report that shares of Samsung Electronics and SK Hynix fell further on Tuesday, extending a recent selloff. CNBC reports that SK Hynix closed 10% lower and Samsung fell 7.4%. The reports link the decline to several factors. Bloomberg cites concerns about Chinese rivals and a stretched AI stock rally. CNBC ties it to ChangXin Memory Technologies, or CXMT, which said over the weekend it had made progress on new chip designs. The Financial Times points to a ‘casino’ comment by the head of Broadcom about AI investment. CNBC also reports CXMT, which listed in Shanghai in July, has a market value of about $520 billion.
