South Korea extends stock trading into evening hours — TradingView News

South Korea’s main stock exchange is extending trading until 8 p.m. as it seeks to attract more overseas investors and move closer to its goal of round-the-clock markets.

Starting Monday, investors will be able to trade nearly all locally listed stocks for another 4½ hours after the regular 3:30 p.m. close. The change makes Korea Exchange the first major Asian bourse to offer such extensive evening trading.

About 2,400 stocks listed on the Kospi and Kosdaq markets will be eligible, along with short selling. Exchange-traded funds are excluded for now. Korea Exchange also plans to introduce premarket trading by the end of 2027.

Longer hours could make Korean shares more accessible to investors in Europe and other regions, while allowing faster reactions to earnings reports and news released after the regular close. The change may eventually attract additional foreign capital and boost the appeal of major stocks such as Samsung Electronics SSNLF and SK Hynix SKHY. However, thin evening volume could produce wider bid-ask spreads, sharper price swings and higher trading costs, particularly for large orders.

The initiative follows a powerful but volatile year for South Korean equities. The Kospi more than doubled before a July selloff erased 22% from its peak. Even after that decline, the benchmark remains up 64% in 2026, making it the best-performing major stock index worldwide.

South Korea already has some experience with extended trading. Nextrade, an alternative trading platform launched in March 2025, offers premarket and evening sessions in roughly 600 stocks. It captured almost one-third of local trading activity within several months, although retail investors generated more than 80% of its volume outside regular hours.

That retail concentration highlights the main challenge for Korea Exchange. Longer sessions provide more opportunities to trade, but they do not guarantee enough buyers and sellers to support efficient pricing. Institutional investors may hesitate to place large orders until evening liquidity improves.

Currency hedging presents another obstacle. Although South Korea’s foreign exchange market operates around the clock, trading in the won can be sparse during off-peak periods. Higher hedging costs could limit participation by overseas funds.

Despite those risks, the extended session represents another step in South Korea’s effort to modernize its capital markets. It will give more investors a chance to respond to late-breaking developments, but the program’s success will depend less on the clock than on whether meaningful trading volume follows it into the evening.
