Korean Stocks Plunge 16% in Two-Day Burst of Retail Selling

South Korean stocks extended their brutal selloff Wednesday, pushing the KOSPI's monthly decline to a record 33%. The two-day plunge saw the index drop 16% as retail investors capitulated, marking one of the sharpest collapses in the exchange's history.

The selloff reflects mounting despair among South Korea's massive retail trading community, which has been a dominant force in domestic equities for years. The 33% monthly drop eclipses previous records and comes as sentiment craters across Korean markets.

The velocity of the decline—16% across just two sessions—suggests panic selling rather than orderly repositioning. Korean retail traders, who gained prominence during pandemic-era rallies, are now facing unprecedented losses as the KOSPI erases months of gains.

The collapse raises questions about market structure and the sustainability of retail-driven rallies that characterized Korean equities in recent years. With the index down one-third in a single month, technical damage is severe and capitulation signals are flashing across the market.
