2026 year 7 month 7 day, KOSPI 8%-range plunge triggered a circuit breaker, temporarily halting trading and heightening investor anxiety.
In the morning, a 5%-range plunge first triggered a sell-sidecar, followed by a circuit breaker. This was the sixth circuit breaker and the sixteenth sidecar this year.
Just before the market opened, the index started at 7,919.20. It fell below 7,700 during the session's plunge.
Samsung Electronics announced record-breaking results that day. However, the announcement did not lead to a rebound in the index afterward.
During the session, program trading and orders from individual investors diverged, increasing volatility. As a result, bid and ask quotes changed sharply for some stocks.
The temporary suspension of trading and order restrictions directly affected the flow of on-exchange trading that day. Under the securities market operating rules, the timing of the resumption and additional disclosures are expected to follow.
The activation time this time was recorded as the morning of 2026year 7month 7day. Market participants are checking bid and ask quotes and the execution speed after trading resumed.
Market reactions are expected to continue as soon as the timing of the resumption of trading and the details of additional disclosures emerge.
