Also known as: Pre-market and post-market sessions

Sessions

On September 14, 2026, the Korea Exchange opened a real-time after-hours market from 4:00 to 8:00 p.m. KST, where orders match as soon as prices meet, and scrapped the old 10-minute single-price auctions that ran from 4:00 to 6:00 p.m. The price limit is the same as the regular session, ±30% from the previous close. KONEX stocks, stocks that did not trade in that day's regular session, stocks under administrative supervision or investment warnings, and ETFs and ETNs are excluded at first. Closing-price sessions around the regular session and the alternative venue Nextrade (pre-market 08:00–08:50, after-market 15:30–20:00) also exist, so check what your broker offers.

Why use it

Investors react to earnings, filings or overseas news released after the close, or trade shares they missed during the regular session.

What to keep in mind

Volume is thinner than in the regular session, so prices can swing and orders may not fill. A big after-hours gain does not guarantee the stock will rise in the next regular session.
