The Korea Exchange is evaluating a proposal to extend its trading hours to 12 hours, according to South Korean media reports. A working group will be established to study the feasibility of this extension, which would include pre-market and after-market trading sessions. The proposed new trading hours could be from 7:00 AM to 7:00 PM or 8:00 AM to 8:00 PM. Currently, the exchange operates from 9:00 AM to 3:30 PM, with an after-market session from 3:40 PM to 6:00 PM.
