The KOSPI Index started the 20th on a downward trend, widening its loss to over 2%.

Top market cap stocks like SK hynix (-4.18%), LG Energy Solution (-1.82%), and KB Financial Group (-1.92%) all flashed red.
Notably, nuclear-related stocks suffered a steep simultaneous decline. Korea Electric Power Corporation Engineering & Construction (KEPCO E&C) (-9.41%), Doosan Enerbility (-8.07%), and Woojin (-7.47%) were all sliding.
