The KOSPI index experienced a significant decline, extending a historic selloff driven by a panic over AI valuations and the unwinding of retail leverage. This downturn was exacerbated by sharp drops in semiconductor giants Samsung Electronics and SK Hynix, which together constitute over half of the KOSPI's weighting, overshadowing positive geopolitical news.
The KOSPI index plunged over 4%, extending a historic selloff that saw its worst monthly performance since 2008. This is primarily due to a 'panic over artificial intelligence' valuations and fears of slowing hyperscaler spending, leading to an unwinding of retail leverage. Samsung Electronics and SK Hynix, which account for over half of the KOSPI's weighting, tumbled nearly 8%, making the broader market highly vulnerable. This event highlights a significant recalibration of AI-related stocks, impacting South Korean equities despite positive geopolitical news regarding Iran. Traders face a key risk in the short-term due to continued volatility in the tech sector, particularly in memory-chip makers, but potential long-term opportunities if AI valuations stabilize.
