美股午盘 — 2026-05-13

市场概览 #

美股周三午盘走势分化，科技股承压拖累纳指，而医疗与必需消费等防御板块逆势走强，道指微幅收涨。4月PPI数据远超预期（同比+6%，环比+1.4%），为2022年12月以来最大增幅，重燃市场对通胀粘性的担忧，国债收益率升至六周高点，市场已完全排除年内降息预期。与此同时，特朗普启程访华、英伟达CEO黄仁勋同机随行，为科技板块带来局部提振，但未能扭转高估值成长股的整体弱势。WTI原油突破101美元，中东地缘风险持续升温。

U.S. equities traded mixed at midday Wednesday. Technology stocks dragged the Nasdaq lower, while defensive sectors—healthcare and consumer staples—outperformed, allowing the Dow to eke out a small gain. April PPI surged well above expectations (+6% YoY, +1.4% MoM), the largest increase since December 2022, reigniting concerns about sticky inflation. Treasury yields rose to six-week highs, and markets have fully priced out rate cuts this year. Meanwhile, President Trump’s departure for China—accompanied by NVIDIA CEO Jensen Huang—provided a sentiment boost to select tech names, but failed to reverse the broader weakness in high-multiple growth stocks. WTI crude broke above $101 as Middle East geopolitical risks continued to escalate.

板块轮动 #

Defensive sectors dominated the session as the hotter-than-expected PPI print triggered a rotation out of rate-sensitive growth names. Healthcare (XLV +1.96%) and Consumer Staples (XLP +1.28%) led the board, attracting safe-haven flows amid renewed inflation anxiety. Financials (XLF +0.78%) benefited from the sharp backup in Treasury yields, while Energy (XLE +0.70%) held firm on the back of persistently elevated oil prices. Technology (XLK -1.51%) and Consumer Discretionary (XLY -0.90%) bore the brunt of the selling, as stretched valuations in software and e-commerce came under pressure from the repricing of the Fed path. The Russell 2000’s underperformance (-1.76%) confirmed that smaller, more speculative names remain vulnerable in a rising-rate environment.

防御板块主导今日交易，PPI数据超预期火热触发了资金从利率敏感型成长股向安全资产的轮动。医疗（XLV +1.96%）和必需消费（XLP +1.28%）位居涨幅榜首，在通胀焦虑重燃之际吸引了避险资金。金融（XLF +0.78%）受益于国债收益率大幅上行，能源（XLE +0.70%）则在持续高企的油价支撑下保持坚挺。科技（XLK -1.51%）和可选消费（XLY -0.90%）承受了主要抛压，软件和电商板块的高估值在美联储路径重新定价的冲击下承压。罗素2000的大幅落后（-1.76%）确认了小市值、高投机性个股在加息环境中依然脆弱。

地缘冲突追踪与美股影响 #

1. 伊朗战争 / 霍尔木兹海峡 #

最新态势:

The Iran-U.S. ceasefire entered its 75th day, but the diplomatic track appears frozen. Tehran’s foreign ministry characterized the latest U.S. counter-proposal as “surrender, not negotiation,” while President Trump called Iran’s proposal “garbage” and said the ceasefire is “on life support.” The IRGC commander’s posture statement has held top billing on Iranian state media for three consecutive days—a historical pattern that has preceded asymmetric kinetic events. The 48-to-96-hour window for a low-level Iranian action (small-craft probe, UAV swarm, or shipping-targeted strike) remains open through Friday. Meanwhile, Saudi Aramco CEO Amin Nasser warned that global gasoline and jet fuel inventories could reach “critically low levels” ahead of summer if the strait stays closed, with cumulative supply losses already exceeding 1 billion barrels and another 100 million barrels lost weekly. The U.S. disclosed that China has given “high-level assurances” against transferring surface-to-air missiles to Iran—a narrower commitment than a full arms embargo but one that forecloses the air-defense category most threatening to any renewed U.S. air campaign. Separately, Kuwait accused Iran’s IRGC of launching an armed incursion onto Bubiyan Island, and the UK announced it will send Typhoon fighter jets, mine-hunting drones, and HMS Dragon to the Gulf.

美伊停火进入第75天，但外交轨道似乎已冻结。伊朗外交部将美方最新反提案定性为"投降而非谈判"，特朗普总统则称伊朗提案为"垃圾"，并表示停火协议"靠生命维持"。伊朗革命卫队指挥官的姿态声明已连续三天在伊朗官媒置顶——这一历史模式通常预示着不对称军事行动。48至96小时的低烈度行动窗口（小型船只试探、无人机群袭或航运目标打击）在周五前仍然开放。与此同时，沙特阿美CEO纳赛尔警告称，若海峡持续关闭，全球汽油和航空燃油库存可能在夏季前降至"极低水平"，累计供应损失已超10亿桶，每周再损失1亿桶。美国披露中国已作出"高层保证"不向伊朗转让防空导弹——这比全面武器禁运承诺更窄，但关闭了任何 renewed 美国空袭中最具威胁的防空类别。另据报道，科威特指控伊朗革命卫队对布比延岛发动武装入侵，英国宣布将向海湾派遣台风战机、猎雷无人机和HMS Dragon号军舰。

关键时间节点:

• 4月8日：美伊停火协议生效
• 5月3日：美国宣布"自由行动"（Project Freedom）护送商船
• 5月4日：两艘美军驱逐舰穿越海峡，马士基船只成功护航通过

2. 俄乌战争 #

最新态势:

The Russia-Ukraine conflict remains in a prolonged stalemate with no major battlefield shifts reported today. Ukrainian presidential chief of staff Andriy Yermak faces a widening corruption probe, which Brussels and key European capitals are watching closely. A statement that quarantines the case from the aid file means the next tranche moves on schedule; a linkage signals Kyiv enters June with degraded political capital and reduced military support. Russian drone strikes continued overnight. European defense spending remains elevated, with NATO members continuing to boost military budgets.

俄乌冲突持续陷入僵局，今日无重大战场变化报道。乌克兰总统办公厅主任叶尔马克面临的腐败调查持续扩大，布鲁塞尔及欧洲主要成员国正密切关注。若欧洲将案件与援助脱钩，下一批援助将按期发放；若两者挂钩，则意味着基辅将在6月份面临政治资本下降和军事支持减少的局面。俄军无人机夜间袭击持续。欧洲防务支出保持高位，北约成员国继续增加军费预算。

3. 全球关税 / 贸易冲突 #

最新态势:

President Trump arrived in Beijing on May 13 for a two-day state visit, accompanied by a high-level business delegation including NVIDIA CEO Jensen Huang. U.S. Trade Representative Jamieson Greer confirmed over the weekend that the U.S. will move forward with plans to raise EU car import tariffs to 25%. The White House is also reportedly considering an executive order to create an AI oversight working group, potentially adding regulatory uncertainty for tech giants. Treasury Secretary Scott Bessent stated gas prices are affecting Americans but expected to come down quickly after the Iran conflict ends.

特朗普总统于5月13日抵达北京，开始为期两天的国事访问，陪同人员包括英伟达CEO黄仁勋率领的高级别商业代表团。美国贸易代表格里尔上周末确认，美国将继续推进将欧盟汽车进口关税提高至25%的计划。此外，白宫据报道正在考虑发布行政命令，成立人工智能监管工作组，可能为科技巨头增加监管不确定性。财政部长贝森特表示汽油价格正在影响美国民众，但预计在伊朗冲突结束后会迅速回落。

专家研判 #

受益板块:

• 国防军工 (LMT / RTX / NOC): 伊朗战争成本已达$290亿且持续攀升，美军在海湾维持大规模部署，2026财年国防预算追加概率显著上升。
• 能源上游 (XOM / COP / OXY): 即使海峡不全面关闭，地缘政治风险溢价将持续支撑油价在$95-110区间。沙特阿美的库存警告进一步强化了供应紧张的叙事。
• 黄金 (NEM / GOLD): 央行购金+避险需求双重驱动，短期回调提供布局机会。
• 油轮 (FRO / DHT): 航线绕行和红海危机叠加，VLCC运价维持高位。
• 网络安全 (CRWD / PLTL): 关键基础设施网络防护需求结构性上升。

回避板块:

• 航空 (DAL / UAL / AAL): 燃油成本上升+需求受经济不确定性拖累，航空票价加速上涨已开始抑制需求。
• 高估值科技 (NVDA / MSFT / TSLA): 波动率回升期，高beta标的首当其冲；PPI过热进一步压缩估值空间。
• 出口制造 (CAT / DE): 关税壁垒+全球需求放缓双重挤压。

情景分析 — 霍尔木兹海峡风险:

关键主题 #

• PPI过热重燃"滞胀"担忧: 4月PPI同比+6%、环比+1.4%双双远超预期，能源价格同比+22.7%，核心PPI +5.2%。市场已完全排除年内降息预期，加息概率升至40%。国债收益率曲线 bear steepening，对高估值成长股构成持续压力。
• 特朗普访华的地缘博弈: 总统携英伟达CEO访华，既为科技合作打开想象空间，也试图在伊朗问题上争取中国更明确的支持。中国关于不向伊朗提供防空导弹的保证是有限但具体的进展。市场关注峰会是否能为霍尔木兹僵局带来突破。
• 能源危机逼近: 沙特阿美CEO的库存警告将市场注意力从单纯的油价数字转向成品油供应安全。若海峡封闭延续至夏季驾驶旺季，汽油和航空燃油短缺可能引发新一轮通胀螺旋，进一步压缩美联储的政策空间。
