Korea Exchange to Launch Stock Market Aftermarket Starting on the 14th

The Korea Exchange will open an aftermarket on September 14 to respond to the liquidity competition with major U.S. exchanges and to expand investment opportunities for investors.

Aftermarket

According to the exchange on September 9, until now, trading was possible from 4 p.m. to 6 p.m. through call auction with single-price trades every 10 minutes. The switch to a continuous auction method means an extension of trading hours.

Originally, the exchange aimed to launch both a pre-market and an aftermarket by the end of June, but adjusted its schedule to prioritize opening only the aftermarket first, reflecting industry feedback. In addition, a mock market was operated for 23 weeks in an environment identical to the actual market to prepare the system setup.

In the aftermarket, exchange-traded funds (ETFs) and exchange-traded notes (ETNs) will be excluded from the list of tradable securities in consideration of market volatility. Only limit orders (market orders excluded) will be allowed. The same price fluctuation limits as in the regular market (±30% from the previous closing price) and measures such as the volatility interruption device (VI) will be applied.

While alternative trading systems (ATS) aftermarkets limit trading mostly to large-cap stocks, the exchange expects to maximize benefits by allowing trading of all listed stocks except for a few that require market management.

The exchange stated, "To continuously enhance the competitiveness of our capital market infrastructure, we will keep monitoring global exchanges' trend of extending trading hours and review phased extensions of trading hours going forward."
