South Korean Stocks Decline Amid AI Bubble Concerns

South Korean stocks declined during trading today, impacted by renewed fears regarding AI sector valuations, prompting investors to reduce risk after a brief rally.

According to TradingEconomics, the KOSPI index fell by 1.57% to approximately 4,101 points, retreating from levels close to its monthly high.

Pressure from Wall Street and the Tech Sector

The decline in the Korean market followed a drop in US stocks on Friday, after Broadcom issued weaker-than-expected forecasts for its AI-related business margins, reigniting fears that massive investments in AI infrastructure may not translate into strong near-term returns.

This raised questions about the sustainability of high valuations for technology stocks, particularly in the semiconductor sector.

Losses Among Leading Stocks

Semiconductor companies led the losses, alongside several major industrial stocks, including:

• Samsung Electronics: −3.31%
• SK Hynix: −3.33%
• Hyundai Motor: −1.82%
• Doosan Enerbility: −3.14%
• Hanwha Aerospace: −4.27%
• HD Hyundai Heavy Industries: −3.14%

Limited Gains in the Biotech Sector

Conversely, some biotech stocks defied the overall trend, recording gains, notably:

• Samsung Biologics: +4.31%
• Celltrion: +0.59%
• LG Chem: +0.34%
