主要涨跌来自晶片与 AI 硬体龙头：SK Hynix 几乎上涨 13% 创新高，台积电上涨 6.6%，Samsung Electronics 也上涨超过 5%，凸显亚洲在 AI 热潮中的关键角色，得益于制造主导力与资料基础设施的扩张。中国大陆与日本市场因假期部分休市，且区域内表现分化；能源依赖型的印度、印尼与菲律宾落后，因投资人担忧战争推高油价将推升通膨并恶化外部收支压力。同时，Donald Trump 表示美国将在星期一开始放行部分中立船舶，但同时维持对伊朗港口的海军封锁，这使霍尔木兹海峡运输风险仍偏高。WTI 原油上涨 1.5%，到 103 美元/桶（约每公升 0.65 美元）。
板块与个股表现显示市场同时存在弹性与脆弱：台北的 MediaTek 在第一季获利优于预期且 AI ASIC 收入展望上修后创新高。Samsung Securities 因与 Interactive Brokers 推出跨境交易合作而暴涨 28%。电动车供应链相关与电动车制造商在需求与获利展望改善下上涨；Prada、MiniMax 及部分香港地产股亦因估值修正与乐观预期而上涨。相比之下，National Australia Bank 跌幅高达 4%。卖方研究指出，已有约 63% 的 S&P 500 公司公布了第一季财报，且获利与指引仍偏强，受到 hyperscalers 与半导体公司的支撑。因此 AI 上行主题仍具延续性，但地缘政治与高油价仍被视为重要约束。
A rally in AI-linked shares helped Asia erase losses tied to the Iran war. The MSCI Asia Pacific Index rose as much as 2.3% on Monday, with South Korea and Taiwan benchmarks up more than 4.5% each, after the S&P 500 extended a record streak to a fifth straight week of gains on strong mega-cap tech results. The AI theme, muted during the early shock of Middle East conflict, returned after the U.S.-Iran ceasefire calmed sentiment. Asia gained more than 13% in April, almost fully offset March declines, and stood up about 15% year-to-date.
Top contributors were chip and AI hardware leaders: SK Hynix surged nearly 13% to a record, TSMC climbed 6.6%, and Samsung Electronics advanced over 5%, underscoring Asia’s role in the AI boom backed by manufacturing dominance and data infrastructure expansion. Mainland China and Japan were partly closed for holidays, and performance diverged across the region. Energy-dependent India, Indonesia, and the Philippines lagged as investors worried the war-driven oil spike would raise inflation and weaken external balances. Meanwhile, Donald Trump’s comments on maintaining the naval blockade of Iranian ports while only easing passage for certain neutral ships from Monday left shipping risk elevated. WTI crude rose 1.5% to $103 a barrel, about 103 USD per barrel (roughly 0.65 USD per litre).
Sector moves showed both depth and fragility: MediaTek hit a record in Taipei after first-quarter earnings beat expectations and AI ASIC guidance improved. Samsung Securities jumped 28% after a cross-border-trading partnership with Interactive Brokers. EV-related supply-chain and EV manufacturers rose on demand and earnings hopes, while Prada, MiniMax, and some Hong Kong property names gained on valuation and sentiment upgrades. By contrast, National Australia Bank fell up to 4%. Sell-side data said about 63% of S&P 500 companies had reported first-quarter results, and both earnings and guidance remained strong, helped by hyperscalers and semiconductor firms. The upside theme therefore remains active, but oil prices and geopolitical uncertainty were still viewed as constraints.
