After Two Days of Gains, Another 'Black Friday'... KOSPI Plunges Over 6% as Sell-Sidecar Is Triggered

The KOSPI is showing a sharp decline of around 6% during intraday trading.

As of 11:48 a.m. on June 26, the KOSPI stood at 8,330.95, down 599.35 points (6.71%) from the previous trading day. The index started the session at 8,813.18 and continued its downward trend, falling below the 8,300 mark.

Individual investors are continuing to buy, but the KOSPI is falling due to selling pressure from foreign investors and institutions. Individuals have made net purchases of 3.3668 trillion won, while foreign investors and institutions have recorded net sales of 2.7690 trillion won and 659.6 billion won, respectively.

The sharp drop in the KOSPI also triggered a sell-sidecar. At around 11:12 a.m. on the same day, program trading quotes were suspended due to volatility in the KOSPI200 index. The sidecar is triggered when the KOSPI200 futures index falls by 5% or more and stays at that level for at least one minute.

Meanwhile, shares of Samsung Electronics and SK hynix are also plunging. Samsung Electronics is trading at 331,500 won, down 7.53% from the previous day, while SK hynix is trading at 2,680,000 won, down 8.12%.
