On Thursday, South Korean shares surged by 2.21%, with the benchmark KOSPI closing at 6,226.05, the highest level since February 27. This increase is attributed to growing optimism regarding a potential agreement between the United States and Iran to end the ongoing conflict, alongside a rally in chipmakers following strong earnings from Taiwanese semiconductor giant TSMC, which reported a 58% increase in first-quarter profits. Major South Korean firms, including Samsung Electronics and SK Hynix, experienced significant stock price increases, with Samsung rising 3.08% and SK Hynix gaining 1.67%. Overall, 657 out of 905 traded stocks advanced, indicating a robust market day. Foreign investors were net buyers, acquiring shares worth 464.4 billion won (around $315.43 million), further bolstering market confidence. The South Korean won also appreciated slightly against the U.S. dollar, closing at 1,473.1 won per dollar.
