Korea Exchange (KRX) said on the 14th, the first day of the aftermarket (night call auction), that the transaction value reached 1.8 trillion won. That is 6.6% of the total transaction value combining the regular session and the aftermarket that day.
The exchange opened the aftermarket, operated as a call auction, from 4 p.m. to 8 p.m. on the 14th. Accordingly, the after-hours single-price trading that used to run from 4 p.m. to 6 p.m. was abolished.
On the first trading day, the transaction value totaled 1.8 trillion won, including 1.3 trillion won on the main board and 492.4 billion won on KOSDAQ. Trading volume was 72.24 million shares (KOSPI 22.17 million shares, KOSDAQ 50.06 million shares). Including the regular session and the aftermarket that day, the total KRX transaction value was 27.6 trillion won.
The eligible universe expanded from about 600 issues to most KOSPI and KOSDAQ listed issues (2,501). However, issues not traded in the regular session that day, issues under administrative status, investment warning (risk) issues, abnormally surging issues, issues under liquidation trading, short-term overheating issues, and issues with insufficient listed shares were excluded from eligibility. Transactions were executed in 2,413 issues, or 96% of these.
By time slot, the transaction share was evenly distributed. From 4 p.m. to 5 p.m. it was 19.6%, 5 p.m. to 6 p.m. 25.5%, 6 p.m. to 7 p.m. 24.2%, and 7 p.m. to 8 p.m. 30.7%.

By order channel, mobile trading systems (MTS) accounted for 73%, and HTS for 21%.
Korea Exchange (KRX) plans to continue monitoring so the aftermarket can take root stably going forward.
