Retail Investors Face 425.8 Billion Won in Forced Liquidations
Retail investors who borrowed funds to invest faced large-scale forced liquidations. From the 1st to the 10th of the month, the value of stocks forcibly sold due to investors' failure to repay borrowed funds on time reached 425.8 billion won. Margin trading allows investors to borrow money from securities firms for three trading days when settlement funds are insufficient. If the shortfall is not covered within the specified period, the securities firm forcibly sells the stocks at a price lower than the market rate on the next trading day.
Concerns have emerged that a sudden influx of forced liquidation volume into the market during periods of extreme volatility could further depress stock prices.
