Korea Exchange Opens Evening Trading for 2,400 Stocks

Korea Exchange will open evening trading sessions on Monday, September 14. The extension covers nearly all local stocks. Traders can buy and sell until 8 pm. This follows the regular close at 3:30 pm. It is the first major Asian exchange to offer such hours.

The exchange seeks to attract global investors. European business hours will now overlap with Korean trading. This move follows a trend led by Nasdaq and the New York Stock Exchange. The goal is to support 24-hour market access.

Liquidity Constraints Limit Initial Participation

Market participants question the depth of evening trading. Previous extended currency sessions showed thin volume. The Kospi index doubled in 2026 before a 22 per cent drop. Turnover contracted sharply during that period. The index remains up 64 per cent year to date.

Dave Mazza of Roundhill Financial notes the risk. He states that extending hours redistributes existing liquidity. It does not create new volume. Institutional investors will wait for sufficient buyers and sellers. Large trades in stocks like Samsung Electronics may be difficult.

Retail Investors Drive Early Activity

Nextrade offers a precedent for non-regular sessions. It launched pre-market and evening trading in March 2025. Retail investors accounted for over 80 per cent of activity. Institutional participation remained low. Price swings were erratic during the initial months.

Korea Exchange now includes 2,400 Kospi and Kosdaq stocks. Short-selling is permitted during these hours. ETFs are excluded from the initial rollout. The exchange plans pre-market hours by the end of 2027. This expands the scope beyond previous alternative trading systems.

Currency Hedging Adds Transaction Costs

Foreign funds face challenges in managing currency risk. The South Korean forex market technically runs 24 hours. Off-peak trading remains thin. This increases the cost of hedging. Higher costs may discourage large capital commitments to evening equity trades.

Park Sanghyun of Clepsydra Capital highlights execution risks. Moving large blocks in thin markets can cause price slippage. Buyers may pay more than expected. Sellers may receive less. This volatility is a primary concern for institutional desks.
