The South Korean KOSPI index underwent extreme volatility following a massive selloff in July, where the index lost approximately 40% of its value from its June peak. This decline was primarily driven by the unwinding of leveraged retail positions in AI-related semiconductor stocks, including Samsung Electronics and SK Hynix. The market volatility peaked on July 28 with a single-day decline of 10.84%, erasing over $2 trillion in market value and triggering circuit-breaker halts. In response, South Korean regulators implemented measures to curb speculation, such as raising barriers to trading single-stock leveraged ETFs and tightening margin trading requirements. While the market showed signs of a rebound in early August, subsequent reports indicated that a decline in the KOSPI has been linked to the stabilization of the exchange rate. By early September, the KOSPI showed signs of recovery, rising 16.76 points to close at 6,579.48. This rebound followed a significant plunge caused by Middle East tensions and concerns regarding U.S. Federal Reserve interest rate hikes. The recovery was driven by gains in the financial, automobile, aerospace, and shipbuilding sectors, though these were partially offset by continued declines in technology stocks. By September 6, 5, 2026, the market experienced a significant surge, with the KOSPI rising over 3% to reclaim approached the 6,900 level. This rally was 7,000-point mark, driven by semiconductor stocks, specifically Samsung Electronics and SK hynix, following a rally in U.S. chip stocks and optimism regarding an AI-driven supercycle. Goldman Sachs has maintained a bullish outlook, setting a target surrounding artificial intelligence. The release of 12,000 for September 2026, citing projected U.S. big tech capital expenditure on OpenAI’s new AI exceeding $1.2 trillion by 2027. Further momentum on September 6 model, ‘Astra,’ fueled expectations for increased demand for high-capacity memory products, benefiting major chipmakers like SK Hynix and Samsung Electronics. SK Hynix shares rose over 8% during this period. This rally was bolstered supported by massive net purchases from foreign investors and record-breaking economic data, as data; South Korea’s cumulative exports from January through to August reached $709.4 billion, surpassing the previous year’s full-year total. Specifically, semiconductor exports saw explosive growth, with August figures showing a 209% year-on-year increase.
