Asian equity markets ended mixed on Tuesday, with South Korea staging a historic surge and Japan riding a semiconductor rally, while Malaysia and Hong Kong slipped into the red amid cautious positioning ahead of key US economic data.
The session was dominated by two major themes: a dramatic easing of Middle East tension as Iran and Israel halted strikes against each other, and a powerful rebound in chip and semiconductor stocks that sent Korea's KOSPI to its best single-day gain in years.
Korea Leads with Historic 8% Surge
South Korea's KOSPI index soared 612.52 points, or 8.18%, to close at 8,096.93 -- the strongest single-day performance in recent memory. The rally was driven by a global semiconductor rebound, with Korean chip giants Samsung Electronics and SK Hynix leading the charge as investors rotated back into technology names following weeks of cautious positioning.
Japan Rides the Wave
Tokyo's Nikkei 225 gained 1,591.09 points, or 2.49%, to settle at 65,416.63. Japanese chip equipment makers and exporters benefited from the same risk-on sentiment that swept through Seoul, bolstered further by the weakening yen at around 160.15 per dollar.
Singapore and China Advance
The Straits Times Index in Singapore added 56.78 points, or 1.14%, to 5,023.25, supported by financials and real estate investment trusts. In China, the Shanghai Composite climbed 51.06 points, or 1.29%, to 4,010.03, breaking above the psychologically significant 4,000 level as optimism grew around Beijing's continued stimulus measures.
Malaysia and Hong Kong Lag
In contrast, the FBM KLCI in Kuala Lumpur dipped 4.02 points, or 0.24%, to 1,675.50. Blue-chip financials were the main drag, with Malayan Banking slipping to RM10.62 and Public Bank flat at RM4.77. Trading volume remained subdued as institutional investors appeared to be waiting for clearer directional cues from global markets.
Hong Kong's Hang Seng Index fell 91.16 points, or 0.37%, to 24,565.90. The tech-heavy Hang Seng Tech index also softened after its recent rally, with traders taking profits ahead of upcoming economic data from the Chinese mainland.
Australia's S&P/ASX 200 edged down 20.90 points, or 0.24%, to 8,604.20, as mining stocks came under pressure from softer iron ore prices.
Currencies and Commodities
The ringgit strengthened slightly against the US dollar, with USD/MYR trading at 4.06, down from the previous close of 4.07. The Chinese yuan also firmed, with USD/CNY at 6.7693.
Oil prices retreated on reports that Iraq and the UAE are accelerating the construction of alternative pipelines as crude exports through the Strait of Hormuz remain disrupted. Brent crude fell 1.38% to $92.11 per barrel, while WTI dropped 1.41% to $88.86.
Gold held steady at $4,357.60 per ounce, erasing earlier losses as ceasefire hopes between Iran and Israel provided support despite strong US employment data.
US Pre-Market Outlook
US stock futures pointed to a higher open. S&P 500 futures rose 0.28% to 7,450.75, Dow futures gained 0.19% to 50,995, and Nasdaq futures advanced 0.39% to 29,690.50, with the semiconductor rebound continuing to fuel optimism on Wall Street.
ATVN Verdict
Tuesday's session underscores how quickly sentiment can shift when geopolitical risk de-escalates. The KOSPI's 8% leap is a reminder that semiconductor-linked economies like South Korea remain the most sensitive barometer of global risk appetite. Malaysia, with its more defensive index composition, tends to lag during sharp risk-on moves -- but this also means less downside when the euphoria fades. Traders should watch the Strait of Hormuz situation closely, as any reversal in oil supply expectations could quickly unwind today's gains in energy-sensitive ASEAN markets.
