South Korean equities experienced a significant surge on Thursday, driven by renewed optimism surrounding potential peace negotiations between the United States and Iran, alongside the crucial resolution of labor disputes at Samsung Electronics. These positive developments collectively triggered an automatic buy-side trading halt in the market.
The benchmark Korea Composite Stock Price Index (KOSPI) initiated the day with a robust 3.85 percent gain. By 9:30 a.m., the KOSPI had dramatically escalated by 277.42 points, or 5.27 percent, reaching 7,388.52. This rapid ascent in the South Korean stock market led to a five-minute suspension of buy-side orders in KOSPI futures around 9:23 a.m., as confirmed by the Korea Exchange, reflecting intense buying pressure.
Global market sentiment was bolstered by overnight gains on Wall Street. US stocks advanced sharply following reports indicating that US President Donald Trump announced Washington was nearing the “final stages” of talks with Iran, which also contributed to a decline in crude oil prices. The S&P 500 notably increased by 1.08 percent, the Dow Jones Industrial Average climbed 1.31 percent, and the tech-centric Nasdaq composite added 1.55 percent, setting a positive tone for Asian markets.
Crucially, investor confidence in the local market saw a substantial boost after Samsung Electronics, the world’s leading memory chipmaker, successfully reached a provisional agreement with its labor union. This averted a major strike that had been scheduled to commence on Thursday, removing a significant overhang for the tech sector.
Technology shares globally, and particularly in South Korea, benefited from strong forecasts. US chip giant Nvidia fueled this optimism by predicting second-quarter revenue that surpassed Wall Street’s expectations and unveiling an impressive $80 billion share repurchase program. This news resonated strongly with major Korean chipmakers.
Consequently, leading chip producers on the KOSPI opened with substantial gains, mirroring the positive momentum from Wall Street. Market capitalization leader Samsung Electronics surged by an impressive 6.07 percent, while its key rival in chip manufacturing, SK hynix, advanced a solid 4.53 percent.
The positive sentiment extended across the Samsung group, with shares of its affiliates also trading robustly. Samsung Electro-Mechanics experienced a significant climb of 8.77 percent, and Samsung Life insurance shares jumped by a remarkable 11.54 percent, showcasing broad market strength.
The automotive sector likewise demonstrated strong performance. Industry titan Hyundai Motor saw its shares increase by 7.77 percent, and its affiliate Kia accelerated by 8.77 percent. Hyundai Mobis, the auto parts division, posted an exceptional gain, vaulting 18.32 percent, underscoring a strong day for the entire Korean automotive industry.
