The KOSPI index ended Monday's session slightly higher at 6,755, representing a 0.97% gain [1].
The market volatility highlights the sensitivity of South Korean semiconductor interests to Chinese competition and global artificial intelligence trends. As China aggressively expands its domestic chip capabilities, South Korean investors are reacting to new entrants in the memory market.
Trading began with an opening level around 6,800 [1]. However, the index experienced significant swings throughout the day, eventually dropping to a low of 6,557 [1]. The fluctuations were driven by the market debut of CXMT, a Chinese memory semiconductor company that has achieved a first-place market-cap ranking in China [1].
Investor sentiment was further influenced by news emerging from the San Francisco AI Summit, where several large-scale collaboration announcements were made [2]. These developments created a mixed trading environment. Individual and institutional investors maintained a buying advantage, while foreign investors focused on selling [2].
An anchor for YTN said the KOSPI started with an upward trend but gave back most of those gains during the day to close with a narrow increase [2]. Analyst Yoon Tae-in said the KOSPI shifted toward a decline early in the session [2].
Market participants closely monitored the interplay between the AI summit's optimism and the competitive pressure introduced by CXMT's listing. The resulting tug-of-war between domestic buyers and foreign sellers prevented the index from maintaining its early momentum [2].

The KOSPI's instability reflects a strategic tension in the global semiconductor industry. While AI advancements in the U.S. provide a growth catalyst, the rise of Chinese firms like CXMT poses a direct threat to the market dominance of South Korean memory chip giants. The divergence between domestic and foreign investors suggests that global capital may be hedging against regional competition in Asia.
