Korean stocks showed muted response on the 27th despite announcements of $1.4 trillion in AI investment partnerships, with the KOSPI closing 0.97% higher at 6755.75. The limited market reaction stemmed from foreign investor profit-taking and investor caution ahead of US Big Tech earnings releases, compounded by volatility in semiconductor stocks following Chinese DRAM maker CXMT's 535% IPO surge. Major Korean companies announced massive AI collaborations at the San Francisco AI Summit, including Samsung Electronics' $200 billion MOU with Broadcom and SK Group's $500 billion AI infrastructure cooperation with NVIDIA, yet related stocks saw profit-taking selling pressure. Analysts noted that AI investment expectations were already largely priced into shares, with market participants now focused on verifying actual earnings results and demand sustainability through upcoming conference calls.
Samsung and SK Announce Combined $700 Billion AI Partnerships
At the San Francisco AI Summit, Samsung Electronics signed a $200 billion MOU with Broadcom. SK Group announced a $500 billion AI infrastructure cooperation with NVIDIA over the next five years. SK Group also committed to pursuing long-term supply cooperation worth $250 billion with Microsoft, Anthropic, and Amazon.
Naver shares surged 8.43% following news of NVIDIA's capital increase. Samsung Electronics rose 1.80% and SK Hynix gained 3.24% on the 27th.
Foreign Selling and CXMT IPO Limit Market Gains
Foreign investors engaged in profit-taking sales despite the AI partnership announcements. Chinese DRAM manufacturer CXMT surged 535% above its IPO price on its first trading day, becoming China's largest market capitalization AI stock. The CXMT listing intensified concerns about increased competition in the memory market.
Kang Jin-hyuk, senior researcher at Shinhan Investment & Securities, stated that "foreign investors took profits on related stocks" following the partnership announcements. He added that "CXMT's 471% surge from its opening price to become China's top AI stock by market cap contributed to expanded volatility in domestic markets."
Lee Kyung-min, researcher at Daesin Securities, explained that "the upward momentum of domestic AI and semiconductor-related stocks was limited due to the CXMT listing impact."
US-Iran Tensions Ease as Oil Prices Stabilize
Military confrontation between the United States and Iran entered a de-escalation phase. The two countries continued diplomatic negotiations. International oil prices stabilized, with West Texas Intermediate (WTI) crude futures trading below $85 per barrel.
Kang Jin-hyuk noted that "President Trump temporarily suspended airstrikes on Iran and left room for negotiations, and as Iran and mediating countries continued consultations, concerns about international oil prices including WTI and Brent eased."
