亚洲午盘 — 2026-05-11

市场概览 #

亚洲市场周一午盘呈现极端分化格局：AI芯片超级周期主导下，韩国与台湾市场再度飙升，KOSPI历史性突破7,800点并触发买盘sidecar熔断；A股在存储芯片爆发带动下沪指站上4,200点创11年新高。与此同时，特朗普称伊朗停战回应"完全不可接受"，美伊谈判陷入僵局，WTI原油跳涨5.28%逼近100美元，黄金因通胀预期升温反而承压。地缘风险与科技狂热并存，资金在半导体产业链上呈现激进的risk-on姿态，而油轮、航空等板块则面临重新定价压力。

指数表现 #

• 沪深300为2026-05-08收盘数据；KOSPI涨跌基于前收7,498点计算；日经基于早盘新闻估算；HSI及上证综指基于今日港股通/沪股通涨跌幅推算。

台湾 #

Taiwan’s TAIEX surged 2.96% to 41,974.40, extending its three-week momentum reversal as global chip heavyweights rerate aggressively. The rally tracked Friday’s 5.51% explosion in the PHLX Semiconductor Index, with institutional MOC flows continuing to chase AI-exposed names. Breadth remained healthy, though the pace of gains raises questions about near-term de-grossing risk should US-Iran tensions escalate further. The台币 firmed 0.68% against the dollar to 31.38, offering marginal relief to import-sensitive sectors.

台湾加权指数大涨2.96%至41,974.40点，延续过去三周的动能反转走势，追随上周五费城半导体指数5.51%的暴涨。机构尾盘（MOC）资金继续追捧AI概念股，市场广度保持健康。不过，若美伊紧张局势进一步升级，当前快速累积的涨幅也引发了对短期降杠杆（de-grossing）风险的担忧。台币兑美元升值0.68%至31.38，为进口敏感型板块带来边际舒缓。

韩国 #

The KOSPI smashed through the 7,800 barrier for the first time in history, trading as high as 7,857.63 before settling near 7,829—up 4.42% from Friday’s close of 7,498. The move was so violent that KOSPI 200 futures triggered a buy-side sidecar at 9:43 a.m., halting program buy orders for five minutes after futures jumped 5.10%. Samsung Electronics (005930.KS) rocketed 7.26% to a record 288,000 won, while SK Hynix (000660.KS) soared 12.57% to 1.898 million won, both notching fresh all-time highs. The rally is underpinned by DRAM forward PER collapsing to just 5.17x—well below the 20-year average of 10x—despite 12-month forward net income surging 293% to 537 trillion won. Hyundai Motor Securities lifted its year-end KOSPI target to 9,750, citing the valuation disconnect. Yet cracks are forming beneath the surface: foreign investors dumped a net 704.1 billion won even as retail traders piled in with 617.2 billion won of buying. The EWY ETF has bled over $1 billion in outflows this month, even as memory-themed ETFs soaked up nearly $2 billion—classic rotation, not broad-based accumulation. A looming Samsung labor strike on May 21 and the Buffett Indicator flashing 256% (above the US peak) add to the overheating warnings.

韩国综合指数历史性突破7,800点大关，早盘一度触及7,857.63点，随后回落至7,829.31点，较上周五收盘7,498点大涨4.42%。涨幅之猛烈，致使KOSPI 200指数期货在上午9:43触发买盘sidecar熔断，程序化买盘暂停5分钟——期货较参考价跳涨5.10%。三星电子(005930.KS)暴涨7.26%至历史新高288,000韩元，SK海力士(000660.KS)飙升12.57%至1,898,000韩元，双双刷新纪录。本轮上涨的核心支撑在于DRAM远期市盈率（PER）已压缩至仅5.17倍，远低于20年均值10倍；而12个月远期净利润则同比暴增293%至537万亿韩元。现代汽车证券将年底KOSPI目标上调至9,750点。但表面繁荣之下已有裂痕：外资净卖出7,041亿韩元，散户却净买入6,172亿韩元；iShares韩国ETF（EWY）本月流出逾10亿美元，而DRAM主题ETF却吸金近20亿美元——这是典型的板块轮动，而非全面累积。此外，三星电子工会计划于5月21日发动18天罢工，以及巴菲特指标飙升至256%（超过美国峰值），均加剧了过热警示。

日本 #

Japan’s Nikkei 225 added approximately 0.95% to 62,575.93, consolidating last Thursday’s historic 5.58% single-session point gain that printed a closing all-time high of 62,833.84. With the five-day Golden Week pent-up buying largely exhausted, today’s move was more measured, led by SoftBank Group which climbed over 2% on AI infrastructure optimism. The broader TOPIX likely tracked modestly higher. USD/JPY held steady near 157.14, with the market pricing in a Bank of Japan rate hike in June as the base case. Every BOJ hike this cycle has produced an 8–15% Nikkei selloff, keeping tactical hedges active despite the secular bull narrative. Exporter names remain vulnerable to yen-strength scenarios if Hormuz reopening hopes fade and oil prices stay elevated.

日经225指数上涨约0.95%至62,575.93点，巩固了上周四历史性大涨5.58%（单日最大点数涨幅）后创下的收盘纪录62,833.84点。随着黄金周累积的五天买盘动能基本释放完毕，今日走势更为温和，软银集团涨超2%，受益于AI基础设施投资乐观情绪。东证指数（TOPIX）大概率小幅跟涨。美元/日元持稳于157.14附近，市场已将6月日本央行加息视为基准情景。本轮周期中，日银每一次加息都引发了日经8–15%的抛售，因此即便长期牛市叙事 intact，战术性对冲仓位依然活跃。若霍尔木兹通航希望消退、油价维持高位，日元升值情景将对出口商构成压力。

香港 #

Hong Kong’s Hang Seng Index drifted 0.29% lower to an estimated 26,317.17, underperforming the regional tech rally as property and financial names weighed. Southbound flows remained supportive, with mainland investors injecting a combined 31.4 billion yuan through both Shanghai and Shenzhen Stock Connect channels—suggesting the valuation gap between HK-listed China tech and their A-share peers continues to attract bargain hunters. However, the HSI Tech sub-index likely faced headwinds from Alibaba and Tencent’s relative sluggishness versus the pure-play semiconductor names dominating sentiment in Seoul and Shanghai. The market is also digesting the US trade court ruling that dealt a partial blow to Trump’s 10% global tariff architecture, though the order was narrowly limited pending appeal.

恒生指数微跌0.29%至约26,317.17点，表现落后于区域科技热潮，地产和金融板块拖累大盘。南向资金持续提供支撑，沪深两市港股通合计净流入约314亿人民币，显示港股中概科技板块与A股同业之间的估值差距仍在吸引抄底资金。然而，恒生科技指数可能受到阿里巴巴和腾讯相对疲软表现的拖累——这两只龙头今日未能复制首尔和上海市场中纯半导体概念的狂热。市场同时也在消化美国国际贸易法院对特朗普10%全球关税架构做出的部分不利裁定，尽管该裁决目前仅限于两个进口商和华盛顿州，且有待上诉。

中国 #

Mainland equities staged a powerful semiconductor-led rally despite the US-Iran gloom. The Shanghai Composite rose 0.94% to approximately 4,219.18—breaching the psychologically critical 4,200 level for the first time in 11 years—while the Shenzhen Component surged 2.13%. The ChiNext board jumped 3.03% and the STAR 50 hit a record high. Storage chip names exploded: 澜起科技(688008.SH) locked in a 20% limit-up, 同有科技(300302.SZ) also hit the 20% ceiling, and 江波龙(301308.SZ) rallied over 14%. The frenzy tracked record-breaking moves in Seoul, where SK Hynix and Samsung Electronics hit fresh peaks. Advanced packaging leader 长电科技 surged to its limit-up, approaching a 100 billion yuan market cap, after guiding 2026 capex to 10 billion yuan for advanced packaging lines. Liquid cooling server plays, optical modules, and PCB makers also ripped higher as the AI hardware buildout narrative intensified. Half-day turnover hit 2.31 trillion yuan, up 339.4 billion yuan from the prior session—confirming genuine demand, not just low-float squeezes. Real estate names saw selective buying on policy-easing chatter.

A股市场在美伊阴霾下仍由半导体板块引领强劲上攻。上证综指上涨0.94%至约4,219.18点，11年来首次突破4,200点心理关口；深证成指大涨2.13%；创业板指飙升3.03%，科创50指数创历史新高。存储芯片概念股爆发：澜起科技(688008.SH)20%涨停，同有科技(300302.SZ)同样封死20%涨停板，江波龙(301308.SZ)涨超14%。这波狂热追随了首尔市场SK海力士和三星电子的纪录新高。先进封装龙头长电科技涨停，总市值逼近1,000亿人民币，此前公司指引2026年资本开支上调至100亿元用于先进封装产线建设。液冷服务器、光模块及PCB制造商亦全线飙升，AI硬件基建叙事持续强化。沪深两市半日成交额达2.31万亿，较上一交易日放量3,394亿——确认这是真实需求推动，而非单纯的小票挤压。地产股在宽松政策传闻下也出现选择性买盘。

资金流向 #

北向资金 #

沪股通与深股通北向资金今日净买入数据均显示为0.0，疑似统计延迟或数据暂未更新。从涨跌家数看，沪股通标的上涨888家、下跌577家；深股通标的上涨1,001家、下跌668家——普涨格局明显，与A股实际强势表现一致。

南向资金 #

港股通（沪）净买入27.98亿人民币，港股通（深）净买入3.40亿人民币，南向资金合计净流入约31.38亿人民币。内地资金持续逢低布局港股，尤其在科技及高股息板块上维持稳定配置节奏。

汇率与宏观 #

地缘冲突追踪与板块影响 #

1. 伊朗战争 / 霍尔木兹海峡 #

Latest: US President Trump declared Iran’s response to the American peace proposal “totally unacceptable” on May 10. Iran, via Pakistani intermediaries, demanded the US Treasury lift oil-sale sanctions within 30 days, requested war reparations, and asserted sovereignty over the Strait of Hormuz. The proposal reportedly included Iran diluting some highly enriched uranium and transferring the rest to a third country, but rejecting dismantlement of nuclear facilities. On May 10, a US merchant vessel was attacked by Iranian drones in the Persian Gulf; US Central Command confirmed over 20 US warships are participating in the naval blockade. Despite the escalation, Iran established two designated shipping channels and a licensing system, slightly improving strait transit—only four vessels were recorded passing as of Monday morning.

最新态势： 美国总统特朗普5月10日称伊朗对美国和平方案的回应"完全不可接受"。伊朗通过巴基斯坦调解方提交回应，要求美国财政部在30天内撤销与伊朗石油销售相关的制裁，并要求美国支付战争赔偿、确认伊朗对霍尔木兹海峡的主权。据报伊方提议将部分高浓缩铀稀释，其余转移至第三国，但拒绝拆除核设施。5月10日，一艘美国商船在波斯湾遭伊朗无人机袭击；美军中央司令部确认超过20艘美军舰参与海上封锁。尽管对峙升级，伊朗已设立两条指定航道和许可制度，海峡通航略有改善——截至周一上午仅记录到4艘船只通过。

关键时间节点： 未来48–72小时美伊是否通过巴基斯坦恢复间接谈判；5月下旬法国/英国计划向红海及霍尔木兹周边增派军舰，伊朗已警告任何域外军事部署将加剧危机。

2. 俄乌战争 #

Latest: Trump brokered a three-day ceasefire through May 11, allowing Putin to hold a subdued Victory Day parade in Moscow—notably without heavy military hardware for the first time since 2007. The truce is expected to expire with limited prospects for extension, and fighting will likely resume in eastern Ukraine. EU defense spending commitments continue to rise, with Germany’s fiscal package underpinning European rearmament.

最新态势： 特朗普促成延长至5月11日的三日停火，普京在莫斯科举行了低调的胜利日阅兵——这是自2007年以来首次没有重型军事装备参加。停火到期后续签前景有限，乌克兰东部战事大概率恢复。欧洲防务开支承诺持续上升，德国财政方案为欧洲重新武装提供支撑。

关键时间节点： 5月11日停火正式到期；5月下旬欧盟对俄新一轮制裁草案表决。

3. 全球关税 / 贸易冲突 #

Latest: A US trade court ruled on May 9 that the 10% temporary global duties imposed under a 1970s trade law were unjustified, though the order was limited to two private importers and the State of Washington pending appeal. Separately, US-China summit expectations are building, with reports suggesting the two sides may institutionalize a trade truce. BYD’s potential US market entry is said to be on the table. The Trump-Xi summit timing remains unconfirmed but is expected in the coming weeks.

最新态势： 美国国际贸易法院5月9日裁定特朗普依据1970年代贸易法实施的10%临时全球关税缺乏法律依据，但裁决目前仅适用于两个私人进口商和华盛顿州，有待上诉。与此同时，中美峰会预期升温，报道称双方可能将贸易休战制度化，比亚迪进入美国市场也被传在谈判桌上。

专家研判 #

相对受益方向：

• AI半导体：三星电子(005930.KS)、SK海力士(000660.KS)、台积电(TSM)、英伟达供应链（内存、封装、PCB）——DRAM PER仅5.17倍，超级周期远未结束
• 石油服务：斯伦贝谢、Halliburton——油价站上$100后上游资本开支预期上调
• 军工防务：Lockheed Martin、雷神、Rheinmetall——欧洲重新武装+中东不确定性双重驱动
• 油轮运输：Frontline、中远海能——绕行导致运力紧张，VLCC运价弹性极大
• 液冷基础设施：冰轮环境、英威腾——AI芯片功耗从B200的1000W向Rubin R300的4000W+跃升，液冷成为唯一选择

需要回避方向：

• 航空客运：国泰航空、中国国航——燃油成本占比超30%，票价传导滞后，利润率被双向挤压
• 零售消费：高通胀侵蚀实际购买力，可选消费复苏脆弱
• 高杠杆房地产：利率敏感度极高，宽松政策预期已部分price in
• 欧洲基础化工：Uniper、BASF——石脑油/天然气路线成本受油价和碳排放双重挤压

情景分析（下一个关键节点：未来48–72小时美伊谈判动向）：

• 基准情景（55%概率）：美伊维持低强度对峙，霍尔木兹部分通航，油价在$95–110区间震荡，市场逐步消化地缘溢价，科技股延续分化上涨。
• 乐观情景（25%概率）：72小时内恢复间接谈判并达成临时框架协议，霍尔木兹全面开放预期升温，油价回落至$85以下，全球风险资产迎系统性反弹。
• 悲观情景（20%概率）：美伊军事冲突升级（美舰遭重大袭击或美方发动空袭），油价突破$120，VIX飙升，全球股市回调5–10%，资金向黄金、美债、日元涌集。

关键主题 #

• AI芯片超级周期：韩国双雄（三星、SK海力士）双双创新高，A股存储芯片涨停潮，摩根士丹利预计亚洲固定资产投资2025–2030年从11万亿增至16万亿美元，核心驱动力为AI基建、能源安全与国防开支。
• 美伊谈判僵局：特朗普"完全不可接受"表态引发油价跳涨，通胀预期再起，黄金反跌，市场在地缘风险与科技狂热之间剧烈分化。
• A股里程碑：沪指站上4200点创11年新高，科创50历史新高，科技自主主线持续强化，半日成交额2.31万亿确认真实需求。
• KOSPI历史时刻：首次突破7800点，KOSPI 200期货触发买盘sidecar熔断，年涨幅已达78%，但外资净流出与散户狂热形成鲜明背离。
• 南向资金持续布局港股：合计净流入约31亿人民币，显示内地资金对港股估值修复的认可，但恒生科技指数跑输A股和韩国芯片板块。
