Korea Exchange Triggers Sidecar, Halts KOSDAQ Program Buying

A sidecar halt on program buying is a mechanical response to sharp futures moves, not a statement on fundamentals, but it matters because it removes a key source of automated bid support from a tech-heavy index for the duration. The signal is about market structure as much as sentiment: when program buying is suspended, order flow thins and price discovery shifts toward discretionary participants. Whether the interruption stays a five-minute technical pause or reflects broader stress in Korean tech positioning is the open question.
