South Korea Stocks Reverse and Drop 5%, Wiping $500 Billion From Asian Markets
South Korean stocks reversed a buying surge to close 5% lower, erasing $205 billion from the KOSPI index and shedding gains secured by a buy-side sidecar. The Korea Exchange triggered the mechanism early in the session to halt program buying during a rally that had briefly added $222 billion to the market.
The sell-off dragged regional markets lower, with the Nikkei dropping 2.1% and wiping $191 billion, while Taiwan's index fell 2% for a $102 billion loss. U.S. stock futures declined, with the S&P 500 E-mini down 0.4%, the Nasdaq 100 futures off 0.9%, and the Dow futures falling 0.3%, as the KOSPI reversal highlighted continued risks from leveraged bets that have driven recent volatility.
