Korea Exchange Triggers Sidecar, Halts KOSPI Program Selling

A sidecar suspension is a mechanical intervention, not a market view: it pauses one category of sell flow without addressing whatever triggered the futures move. The practical effect is to thin liquidity and delay price discovery on the sell side, which can widen the gap between the index and the derivatives that set the trigger. Whether the halt is brief or extended, and whether selling pressure simply resumes once it lifts, is the open question worth watching.
