MSCI亚太指数下跌3%至277.27点。

South Korea’s KOSPI plunged 9.99% on Tuesday, the largest one-day drop in three months, after foreign investors sold following a regulator signal that the chip sector was overheating. CLSA chief equity strategist Alexander Redman said the move exposed heightened volatility driven by heavy retail participation and margin use, warning volatility "has gone out of control" and noting regulator-approved leveraged single-stock ETFs have amplified risks. South Korea’s market regulator acknowledged it was too hasty approving leveraged funds tied to major chip names launched last month and warned retail investors against using leverage as margin debt and financing to buy stocks hit a record high in June.
