Seoul shares experienced a significant surge on Wednesday, with the benchmark Korea Composite Stock Price Index (KOSPI) climbing 3.76 percent to close at 6,598.26. This rebound followed a sharp decline the previous day and a more modest gain on Tuesday. The market's upward momentum was driven by a confluence of factors, including easing concerns over the profitability of artificial intelligence (AI) investments and renewed optimism for a potential interim agreement between the United States and Iran concerning the critical Strait of Hormuz shipping route.
At 9:25 a.m., the Korea Exchange (KRX) activated a buy-side sidecar for the KOSPI index, temporarily suspending program trading for five minutes due to the rapid price increase. Technology stocks were prominent in the day's gains. The positive sentiment in Seoul was also influenced by overnight advances in U.S. stock markets, where investors anticipated that a deal to reopen the Strait of Hormuz could lead to a further decrease in oil prices and alleviate inflationary pressures. Strong quarterly earnings reports from major companies, notably enterprise software firm Palantir Technologies, further bolstered investor confidence by mitigating concerns about the substantial investments being made in the AI sector by leading technology firms.
The Dow Jones Industrial Average rose 1.71 percent to 54,085.88, and the tech-heavy Nasdaq Composite climbed 2.59 percent to 26,584.99, reflecting a broader positive market sentiment.
