Foreign investors’ share of Nextrade trading value rose from 0.4% at its launch to about 14% in July, while the platform’s participating firms increased from 28 to 38 after global brokerages including Macquarie, Morgan Stanley, Merrill Lynch, Goldman Sachs and CLSA joined.
4
The KRX plans to add premarket trading by the end of 2027, extending its longer-term effort to move toward a 24-hour market.

Market participants cautioned that the rollout may not immediately produce a surge in activity: thin liquidity during Korea’s recently extended currency-market hours suggests the new equity session will have to prove that it can attract enough volume.
South Korea's Korea Exchange will extend stock trading until 8 p.m., creating a roughly 12-hour trading window that stretches into European market hours. The after-hours session, launching September 14, will cover nearly 2,400 stocks from the Kospi and Kosdaq indexes—a massive expansion from Nextrade's roughly 610 stocks currently available in evening hours, according to GuruFocus.
The move reflects strong demand for evening access since Nextrade launched in 2025, and rising foreign investor participation. Foreign investors' share of Nextrade trading value jumped from 0.4% at launch to about 14% in July, BigGo Finance reports. The extension aims to attract global capital and edge toward round-the-clock trading, though market experts warn the new session must prove it can generate sufficient liquidity.
A Four-and-a-Half Hour Extension Into European Time
The regular KRX session runs 9 a.m. to 3:30 p.m. The new evening window adds 4.5 hours, until 8 p.m., placing Seoul squarely during European trading hours. Combined with Nextrade's 8 a.m. premarket, investors now access Korean stocks for roughly 12 hours daily, according to BigGo Finance. This alignment with European markets removes a timing barrier for foreign investors who previously had limited overlap with Seoul's trading day.
Nearly 2,400 Stocks Get Evening Access, But Some Stay Out
The expansion dwarfs Nextrade's current 610 eligible stocks. Nearly 2,400 Kospi and Kosdaq listings will trade during the evening session starting September 14, GuruFocus reports. However, some securities and exchange-traded funds remain excluded. The evening session will permit short-selling—a tool currently unavailable in Nextrade's premarket—giving traders more flexibility during the later hours.
Fee Competition and Best-Execution Rules Shape the Landscape
KRX and Nextrade now compete on fees, execution and liquidity. KRX charges about 0.23 basis points per trade, compared with 0.15 basis points at Nextrade. Under best-execution rules, brokers must route orders to whichever venue offers the best combination of price, costs and execution. Global brokerages including Macquarie, Morgan Stanley, Merrill Lynch, Goldman Sachs and CLSA have joined Nextrade since launch, raising the platform's participating firms from 28 to 38.
Caution: Liquidity Success Is Not Guaranteed
Market participants warn the rollout may not immediately boost trading volume. South Korea's recently extended currency-market hours show thin liquidity during off-peak times. The new equity evening session will need to prove it attracts enough volume to function smoothly. The KRX plans to add premarket trading by end of 2027 as part of a longer-term push toward a 24-hour market, but officials acknowledge the extended session must first demonstrate solid investor demand.
