South Korea’s benchmark KOSPI (the country’s main stock index) fell more than 1% to around 6,840 on Friday, snapping a three-day rally. Investors remained cautious ahead of Federal Reserve Chair Kevin Warsh’s speech at the Jackson Hole symposium later in the day, overshadowing a strong overnight Wall Street session driven by Nvidia’s stronger-than-expected earnings and upbeat revenue outlook. Samsung Electronics and SK hynix each declined more than 1%, while Samsung Biologics dropped nearly 5% after announcing plans to raise KRW 3 trillion through a rights offering (new shares offered to existing shareholders). Other decliners included LG Energy Solution, Hanwha Aerospace, HD Hyundai Heavy Industries, SK Inc and LS Electric.
