Korea Exchange activates a sidecar on the KOSPI after KOSPI 200 futures fall 5% with programme trading halted for 5 minutes. A sidecar on the Korea Exchange is a pre-announced, rules-based event rather than discretionary intervention: it fires automatically when KOSPI 200 futures sustain a move of 5% for a defined interval and suspends programme trading for five minutes, leaving continuous order-book trading intact. It sits a tier below the exchange's circuit breakers, which halt the market outright at progressively larger index declines, so the operative question after a sidecar is whether selling pressure exhausts at the programme level or migrates into discretionary flow that tests the next threshold. Episodes of this kind have historically clustered around external shocks rather than Korea-specific news: global risk-off sessions, heavy foreign investor futures selling, or sharp moves in the won, since foreign and programme flows dominate KOSPI 200 futures volume. The pattern on previous occasions has been that the five-minute pause breaks momentum where the trigger was mechanical deleveraging, but merely delays it where the driver is fundamental news. The tells are the composition of futures flow after the halt expires, foreign net selling figures released by the exchange, and whether the won and regional peers are moving in sympathy. Whether the move broadens toward circuit-breaker territory before the close is the established escalation path to monitor. 30 Oct, 01:00 PRE-MARKET CHINESE STOCKS NEWS: Earnings deluge continues 30 Oct, 00:31 SK Hynix (000660 KS) is to construct US NAND memory facility targeting AI data centre needs 30 Oct, 00:25 PRE-MARKET TAIWAN AND SINGAPORE STOCKS NEWS: ASE Technology Holding (3711 TT) raised its annual capex budget for the third time to USD 11.5bln (prev.
