A window on what to watch in after-hours trade once the regular session ends

With the KOSPI closing at 6,967.62 (+2.26%) and KOSPI futures showing foreign net buying of 173 contracts on the day (provisional), after-hours single-stock price discovery will reflect today’s broad gains; the most recent confirmed NXT (Nextrade Alternative Exchange)Korea’s alternative trading system, Nextrade, which runs pre-market, main, and after-market sessions alongside KRX.NXT’s share of total turnover (around 13–15% in recent sessions) provides a real-time read on order flow before and after regular KRX hours. after-market session data available is from August 13, when after-hours turnover reached ₩4,084.9bn across 604 names.In the 2026 regime, on the 31 Fridays in the sample, foreigners were net sellers on average (–₩12,895bn mean, net-buying in only 26% of sessions); today’s provisional foreign net buy of ₩3,037.5bn on KOSPI runs against that base rate, and any reversion in positioning will be visible when U.S. futures open.
