SEOUL, April 07 (AJP) - Asian equities ended mostly higher Tuesday, though gains were limited as investors held back ahead of U.S. President Donald Trump’s self-imposed nighttime deadline for Iran.
South Korea’s benchmark KOSPI rose 0.82 percent to 5,494.78 after swinging between gains and losses through the session. The rebound was helped by renewed foreign buying following Samsung Electronics’ blockbuster first-quarter earnings, which placed it among the world’s four most profitable tech companies alongside Apple, Nvidia and Microsoft.
Still, hopes for a diplomatic off-ramp faded as Iran showed no sign of yielding despite Trump’s sharpest warning yet, threatening to strike power plants and bridges unless Tehran complies by 8 p.m. U.S. Eastern Time. Reports of Israeli strikes on Iranian infrastructure added to concerns over broader regional escalation and possible energy supply disruptions.
Oil prices climbed on those fears. Brent crude rose 1.37 percent and West Texas Intermediate gained 2.3 percent, while the CBOE Volatility Index rose to 24.17, underscoring growing market unease.
Foreign investors led late-session buying in Seoul, purchasing a net 406.9 billion won ($270.4 million) worth of shares. Institutions and retail investors were net sellers, offloading 414.1 billion won and 342.6 billion won, respectively. The shift in flows helped the KOSPI recover from earlier weakness.
Among major stocks, Samsung Electronics gained 1.8 percent to 196,500 won, while SK hynix climbed 3.4 percent to 916,000 won on continued strength in memory-chip prices. Defense shares also advanced, with Hanwha Aerospace jumping 6 percent amid rising geopolitical tensions.
Battery makers were mixed. LG Energy Solution fell 1 percent to 408,500 won after posting a preliminary operating loss of 207.8 billion won, while other secondary battery stocks were comparatively resilient. Automakers edged lower, with Kia slipping 0.5 percent.
The tech-heavy KOSDAQ fell 1.02 percent, reversing early gains as retail and institutional investors turned into heavy sellers. Biotech shares dragged on sentiment, with Sam Chun Dang Pharm plunging 16 percent.
Global semiconductor sentiment remained firm, with the Philadelphia Semiconductor Index rising 1.2 percent to 7,916.1, reflecting continued optimism over AI-driven chip demand.
Elsewhere in Asia, Japan’s Nikkei 225 ended little changed at 53,429.56, while China’s Shanghai Composite added 0.2 percent to 3,886.19. Hong Kong markets remained closed for an extended Easter holiday. The won traded at around 1,504.5 per dollar.
