- Samsung Electronics jumped almost 7% while SK Hynix added 5%, spearheading the market rally
- Morgan Stanley projects KOSPI target of 9,000 with downside protection at 6,000
- The correlation between Kospi and Nasdaq-100 has reached 0.95, showing near-identical movement
- Korean financial authorities have suspended new approvals for leveraged single-stock ETFs
The South Korean KOSPI index staged a significant recovery Tuesday, posting approximately 4% gains as semiconductor heavyweights Samsung Electronics and SK Hynix rebounded from an intense period of decline. The rally followed a punishing week that saw the index shed 9%, contributing to a total retreat of over 30% from its June highs.
Shares of Samsung rocketed nearly 7% higher during Tuesday’s session. SK Hynix posted a solid 5% advance. The pair had suffered significant losses amid growing worries that artificial intelligence-related valuations had become excessive.
Last week’s downturn reflected a broader global technology retreat. AI-focused semiconductor stocks declined despite Taiwan Semiconductor Manufacturing delivering robust quarterly results, as market participants grew skeptical about elevated valuation levels.
Investment bank Morgan Stanley offered perspective, suggesting the correction appears substantial but hasn’t reached full bear market territory. According to the firm’s analysis, semiconductor companies accounted for roughly 70% of the KOSPI’s market capitalization erosion since the second half began.
Morgan Stanley maintained its 12-month KOSPI projection at 9,000 while adjusting its bearish scenario to 6,000, reflecting expectations of moderating earnings expansion. The firm indicated that 6,000 to 9,000 represents the probable trading corridor for the next three to six months.
South Korea as a Gauge for the AI Trade
The South Korean equity market has emerged as one of the most closely monitored proxies for global artificial intelligence investment trends. The market’s substantial exposure to semiconductor companies has created heightened sensitivity to shifts in AI spending expectations.
Evercore ISI analysts observed that the Kospi and Nasdaq-100 now display a correlation coefficient of 0.95, indicating nearly identical directional movement. They characterized South Korea as the “tail that wags the dog” in worldwide financial markets.
Michelle Gibley from the Schwab Center for Financial Research described the market as “effectively a barometer for the AI trade,” highlighting memory semiconductors’ critical position in AI infrastructure and the expanding use of leverage among individual investors.
Leverage Is Amplifying the Swings
Individual investors in South Korea have invested heavily in leveraged single-stock ETFs, especially those tracking Samsung and SK Hynix. This concentration has magnified price movements in both upward and downward directions, with the Kospi activating its circuit breaker mechanism seven times throughout this year.
The market turbulence reached sufficient intensity that South Korean financial regulators implemented a freeze on approvals for additional leveraged single-stock ETFs to reduce speculative trading.
Notwithstanding recent market stress, the Kospi remains up 113% over the trailing 12 months and approximately 60% year-to-date. Morgan Stanley noted that forward-looking valuations for both the index and its chip manufacturers are approaching historical minimums, though uncertainties surrounding AI capital expenditure and supply chain dynamics may sustain elevated volatility.
The investment bank continues to recommend a portfolio approach that combines exposure to technology sector leaders with more stable, defensive positions.
