Lunchtime Buy Sidecars — KOSPI & KOSDAQ Ring Twice Today
Quiz: How many sidecars on July 10, 2026? If you only read the morning tape, you might say zero. Lunch said otherwise. Answer: two — KOSPI buy sidecar at 12:54:55, KOSDAQ buy sidecar around 13:08.
KOSPI 200 futures hit +5.13% (1,240.15) for one minute — the 17th buy-side trip on KOSPI in 2026 (Seoul Shinmun). KOSDAQ followed at +6.26% (Yonhap·Asiae). Not investment advice.
What a sidecar is — buy vs sell
A sidecar pauses program quotes for five minutes. Sell-side (Mon/Tue) blocks program sells; buy-side (today) blocks program buys. Retail keeps trading.
