TOKYO — South Korean stocks fell sharply on Friday, recording their biggest percentage decline in four months due to investor concerns about the downsides of the country’s trade deal with the U.S. and disappointment over a domestic tax reform plan.
The benchmark KOSPI extended its losses from the previous day and closed down 3.9%, marking its biggest pullback since April 7. Big tech names tumbled, led by SK Hynix’s over 5% drop. Samsung Electronics and LG Energy Solution also ended the day lower.
