South Korean Markets Surge 4% as Tech Giants Samsung and SK Hynix Stage Comeback

Key Highlights

• South Korea’s benchmark KOSPI index climbed 4% on Tuesday following a 9% plunge last week and a 30%+ decline from June highs
• Samsung Electronics jumped nearly 7% while SK Hynix added 5%, spearheading the market recovery
• Morgan Stanley keeps its KOSPI price target at 9,000 with a downside scenario level of 6,000
• The Korean benchmark and Nasdaq-100 show a 0.95 correlation coefficient, moving almost identically
• Korean financial authorities have suspended new approvals for leveraged single-stock ETF products

The South Korean stock market staged a significant recovery on Tuesday, with the KOSPI index posting approximately 4% gains as semiconductor heavyweights Samsung Electronics and SK Hynix rebounded from an intense period of liquidation. This rally followed last week’s 9% tumble and a dramatic 30%-plus retreat from the June high-water mark.

KOSPI Composite Index (^KS11)

Shares of Samsung surged close to 7% during Tuesday’s trading session. SK Hynix posted a 5% advance. Both technology leaders had suffered steep declines amid mounting worries that artificial intelligence-related valuations had become excessive.

Last week’s downturn was connected to a broader global technology sector retreat. AI-focused semiconductor stocks experienced pressure despite Taiwan Semiconductor Manufacturing delivering robust quarterly results, as market participants questioned the sustainability of elevated valuations.

Investment bank Morgan Stanley offered perspective, characterizing the pullback as significant but not yet constituting a comprehensive bear market. The firm noted that semiconductor companies accounted for roughly 70% of the KOSPI’s market capitalization erosion since the beginning of the second half.

Morgan Stanley maintained its 12-month price objective of 9,000 for the KOSPI while adjusting its pessimistic scenario to 6,000, citing expectations for more modest earnings expansion. The bank identified a 6,000 to 9,000 range as the probable trading corridor for the upcoming three to six months.

Korean Markets Emerge as Critical AI Investment Barometer

The South Korean equity market has emerged as one of the most closely monitored benchmarks for gauging global artificial intelligence investment trends. The market’s substantial weighting toward semiconductor companies has created heightened sensitivity to any changes in AI capital expenditure sentiment.

Research analysts at Evercore ISI observed that the relationship between the Kospi and the Nasdaq-100 has achieved a 0.95 correlation coefficient, indicating the indices have been tracking each other with remarkable precision. They characterized South Korea as playing a disproportionate role in influencing worldwide asset markets.

Michelle Gibley from the Schwab Center for Financial Research described the Korean market as “effectively a barometer for the AI trade,” highlighting memory semiconductors’ critical position in artificial intelligence infrastructure and the increasing leverage employed by individual investors.

Leveraged Products Magnifying Market Volatility

Individual investors throughout South Korea have directed substantial capital into leveraged exchange-traded funds focused on single stocks, especially products tracking Samsung and SK Hynix. This concentration has intensified price movements in both upward and downward directions, resulting in the Kospi activating its circuit breaker mechanism seven times throughout the current year.

The market turbulence reached sufficient levels to prompt South Korean financial authorities to halt approvals for additional leveraged single-stock ETF products in an effort to reduce speculative trading behavior.

Notwithstanding the recent turbulence, the Kospi has delivered 113% returns over the trailing twelve months and approximately 60% gains year-to-date. Morgan Stanley indicated that forward-looking valuations for both the index and its semiconductor constituents are trading near historical troughs, although ongoing uncertainty surrounding AI capital spending and supply chain dynamics may sustain heightened volatility.

The investment bank continues to recommend an approach that combines exposure to technology sector leaders with more conservative portfolio positions.
