Tech Stock Surge Pushes South Korean Market to Historic High Amid AI Optimism

Technology stocks experienced a massive surge Wednesday, propelling South Korea’s main stock index to an unprecedented peak as investors showed strong enthusiasm for artificial intelligence growth prospects and potential diplomatic breakthroughs in the U.S.-Iran situation.

The Kospi index climbed an impressive 6.7% to reach 7,398.34 after reopening following Tuesday’s holiday closure. Samsung Electronics led the charge with a remarkable 13% jump in share price, while fellow semiconductor manufacturer SK Hynix surged 10% during early trading hours.

Both technology giants play crucial roles in producing the specialized computer chips essential for artificial intelligence systems, positioning them to benefit significantly from the ongoing AI revolution.

Market optimism received an additional boost from reports that Iranian representatives were heading to China prior to scheduled talks between President Donald Trump and Chinese President Xi Jinping. This diplomatic development helped stabilize oil market fluctuations and improved overall investor sentiment.

The positive momentum extended across other Asian trading floors, though Tokyo markets remained closed for a holiday. Australia’s S&P/ASX 200 advanced nearly 1.0% to 8,766.80 during morning sessions, while Hong Kong’s Hang Seng climbed 0.7% to 26,081.52. Meanwhile, the Shanghai Composite posted a 1.0% gain, reaching 4,152.68.

Energy markets saw some cooling, with benchmark U.S. crude declining $1.37 to $100.90 per barrel. International Brent crude dropped $1.50 to $108.37 per barrel, continuing Tuesday’s downward trend that erased earlier weekly gains. Despite these decreases, oil prices remain significantly elevated compared to pre-war levels of approximately $70 per barrel.

U.S. military officials have confirmed a ceasefire agreement with Iran is currently active, though considerable uncertainty persists. American forces are working to reestablish safe passage through the Strait of Hormuz, which would enable oil tanker operations to resume from the Persian Gulf region.

Wall Street also celebrated strong performance, with the S&P 500 advancing 0.8% to establish a new record at 7,259.22, surpassing last week’s previous high. The Dow Jones Industrial Average contributed a 0.7% gain to close at 49,298.25, while the technology-focused Nasdaq composite achieved its own milestone with a 1% rally to 25,326.13.

Economic indicators from the United States presented a mixed picture. Service sector growth unexpectedly decelerated last month, with some businesses citing war-related impacts on consumer spending. However, a separate analysis revealed that employers posted slightly more job advertisements at March’s conclusion than economists had anticipated, suggesting continued strength in the employment market.

Currency markets showed modest movement, with the U.S. dollar edging down to 157.88 Japanese yen from the previous 157.89 yen. The euro strengthened to $1.1720, up from $1.1693.
