Global stock markets experienced a sharp sell-off in artificial intelligence-related shares, led by significant declines in South Korean tech giants Samsung Electronics and SK Hynix following Nvidia's recent losses.

Key Points

• South Korea’s Kospi index closed 10.8% lower on Tuesday after a temporary trading halt triggered by an 8% slide.
• Samsung Electronics and SK Hynix shares both dropped by more than 13% amid heightened volatility in the Asian tech sector.
• Nvidia lost its position as the world’s most valuable listed company to Apple after a 5% decline in New York on Monday.
• Japan’s Nikkei 225 index fell nearly 4% as investors reacted to concerns regarding the long-term profitability of massive AI infrastructure spending.
• China’s ChangXin Memory Technologies saw its shares surge 470% during its Shanghai IPO debut on Monday.

Why it Matters

The market correction highlights growing investor anxiety over whether the billions of dollars being poured into AI data centers will generate sustainable financial returns. This shift in sentiment has prompted a rotation toward more stable assets like Apple, which remains less exposed to the immediate risks of the AI spending race.
