South Korea’s Kospi Surges Over 8%, Adds $425 Billion as Samsung Jumps 11%
South Korea’s Kospi surged more than 8% on June 12, extending the previous day’s rebound as semiconductor heavyweights led the advance. Samsung Electronics rose 11% and SK Hynix gained 8%, helping add more than ₩620.5 trillion ($425 billion) to the country’s stock market; the speed of the move also triggered a buy-side sidecar shortly after the open.
The rally follows a June 11 rebound that restored about ₩305 trillion to South Korean stocks after a selloff tied to US strikes on Iran, with the latest gains coming amid hopes the Middle East conflict will ease. Even with the rebound, Seoul equities have been swinging sharply all week: the Kospi plunged 8.3% on Monday, rose 8.2% on Tuesday and then fell 6.5% on Wednesday, prompting curbs on program trading.
