Ask what Korea is talking about.

South Korea's stock markets will open one hour later than usual on Nov. 19, the day of the nationwide college entrance exam (Suneung), according to the Korea Exchange (KRX). Trading on the main KOSPI, KOSDAQ, and KONEX markets will run from 10 a.m. to 4:30 p.m., while the alternative exchange Nextrade (NXT) will operate from 10 a.m. to 4:20 p.m., with no pre-market session, Yonhap and Chosun Ilbo report. The delay is to ease traffic and ensure smooth exam logistics, as the bourse operator announced the schedule on Thursday, Nov. 5. Korean media outlets, including Kyunghyang Shinmun, note that the pre-market will also be closed that day, and the adjustment applies to all regular sessions.
