‼️South Korea's stock market has become more volatile than Bitcoin: Return volatility on the benchmark KOSPI has reached 63% year-to-date, the highest of any national stock index tracked by Bloomberg. This is also above Bitcoin's own 48% reading over the same period. This comes as Samsung and SK Hynix alone account for more than 50% of the KOSPI's weight, making the index highly sensitive to shifts in sentiment toward a single sector. That concentration is amplified further by Korea's leveraged ETF market, an unusually retail-dominated corner of the market. Combined with the 2 underlying stocks, these leveraged ETFs at one point accounted for more than 70% of daily traded value in Korea's now $3.4 trillion equity market, down from over $4 trillion. Korean retail investors have also purchased more than 110 trillion won, or ~$77 billion, of KOSPI stocks this year, with a tendency to rush in during rallies and stampede out during selloffs, adding further volatility to the index. South Korea's market has become a high-stakes bet on two stocks, amplified by leverage and retail momentum.
