7month 8day, KOSPI plunged intraday by 8%, triggering a circuit breaker, while KOSDAQ fell below the 800-point level intraday as a sidecar was also activated that day. Trading in some issues was temporarily restricted due to the circuit breaker and sidecar.

KOSDAQ fell 46.23points that day to close at 785.00. The decline was 5.56%. Intraday, a plunge of around 3% was observed, and the index fell below the 10-month 800-point level.

The KOSPI plunge was caused by foreign selling. During the decline, sidecar restrictions aimed at curbing sharp index movements were applied to both the KOSPI and KOSDAQ markets.

After the market close, a partial rebound emerged. The KOSPI recovered the 7,700line, and SK hynix, after declining intraday,4 showed strength in the range.

This volatility occurred as 7month 8day trading and foreign order flows acted simultaneously within the market. As trading restrictions were applied, changes arose in trading hours and methods.

Investors should check the time trading resumes, disclosures, and foreign investor flows on the next trading day.
