- Samsung Electronics' stock plunged 7.4% due to direct competitive threats from China's CXMT, which plans to release a next-generation server memory module. This news, combined with Morgan Stanley's caution on semiconductor stock performance ahead of earnings peaks and the completion of Samsung's share buyback program, has pressured the stock. Foreign investors are also exiting Korean equities at a historic pace, contributing to the decline.
Investing.com -- Samsung Electronics stock plunged 7.4% to ₩232,000 on Tuesday pressured by a fresh and direct competitive threat from China, as well as a broader souring in sentiment towards chipmaking stocks.
Samsung clocked extended losses after China’s ChangXin Memory Technologies (CXMT) announced it expects to release a next-generation server memory module by year-end, built on a denser cell architecture that could erode the pricing power underpinning Samsung’s record profits.
The announcement landed just days after Samsung disclosed a preliminary third-quarter operating profit of approximately 107.4 trillion won — a staggering year-on-year surge — yet the market’s reaction has been decisively negative, as investors appear to be pricing in a future where Chinese competition compresses margins well before the current earnings cycle peaks.
Adding to the pressure, Morgan Stanley’s memory chip team had recently cautioned that semiconductor stocks historically begin to underperform four to eight months before earnings actually peak, a dynamic that has amplified selling momentum.
The completion of Samsung’s ₩15 trillion share buyback program — which had been acquiring shares at an average price well above current levels — removed a significant source of price support, while foreign investors continued to exit Korean equities at a historic pace, with net selling on the main board exceeding ₩1.81 trillion in today’s session alone.
The broader Korean market has been in freefall, with the KOSPI plunging more than 6% intraday to breach the psychologically critical 6,000-point level — its sixth straight session of losses — prompting the activation of a sell-sidecar circuit breaker.
Sector peer SK Hynix also fell sharply on the same CXMT news, while U.S. memory rival Micron Technology retreated overnight.
Anticipation of Q3 earnings from chipmaking bellwethers ASML and TSMC, which are due this week, also pressured broader chip stocks.
