美国股市在6月5日遭遇2025年以来最严重的单日抛售，道琼斯工业平均指数暴跌695点，纳斯达克指数下挫百分之四，标普500指数同步大幅下跌。此次暴跌由疲软的非农就业报告和美联储加息预期升温共同触发，AI和半导体板块成为重灾区。

US Stock Market Plunges: Dow Drops 695 Points, Nasdaq Falls 4% on Weak Jobs Data

US stock markets suffered their worst single-day sell-off since 2025 on June 5, with the Dow Jones Industrial Average plummeting 695 points and the Nasdaq Composite diving four percent. The S&P 500 also posted sharp losses, erasing months of gains in technology and artificial intelligence stocks.

The sell-off was triggered by a weaker-than-expected US jobs report that paradoxically increased expectations of Federal Reserve rate hikes, as investors feared that labor market weakness could coincide with persistent inflation. Treasury yields jumped in tandem with the equity decline, reflecting a complex market reaction that defied traditional risk-off patterns.

The technology sector bore the brunt of the decline. Semiconductor stocks led the losses, with major chipmakers seeing their valuations slashed as investors reassessed the timeline for AI monetization. Nvidia, which had been the primary beneficiary of the AI investment boom, saw significant selling pressure.

Amazon and Microsoft demonstrated relative resilience compared to their tech peers, supported by their diversified revenue streams and strong cloud computing growth. However, even these mega-cap stocks posted notable declines as the broad-based sell-off swept through growth-oriented portfolios.

Analysts at major investment banks noted that the AI trade, which had driven unprecedented capital inflows into technology stocks throughout 2025 and early 2026, is now facing its first major correction. The combination of elevated valuations, rising rate-hike odds, and questions about near-term AI profitability created a perfect storm for the sector.

全景透视

此次股市暴跌标志着AI投资热潮可能正在经历首次重大修正。过去一年多以来，人工智能概念推动了科技板块的狂热上涨，大量资本涌入半导体和AI相关公司。然而，随着美联储加息预期升温以及AI商业化变现时间表的不确定性增加，市场开始重新评估这些高估值股票的合理性。

从宏观经济角度来看，就业报告与加息预期之间的复杂关系反映了当前美国经济的结构性矛盾。一方面，劳动力市场疲软通常意味着降息预期；但另一方面，如果通胀仍然顽固，美联储可能被迫在经济增长放缓的背景下维持甚至提高利率。这种"滞胀"风险是股市最不愿意看到的情景。

对于投资者而言，此次回调提供了一个重新审视投资组合的机会。AI技术的长期发展趋势并未改变，但短期估值过高和资金拥挤的问题需要时间来消化。历史经验表明，每一次技术革命都会经历泡沫与修正的循环，关键在于区分短期情绪波动和长期基本面变化。

多方观点

CNBC分析认为，纳斯达克百分之四的跌幅反映了市场对AI板块估值过高的担忧正在迅速转化为实际的抛售行为。Yahoo Finance则指出，美联储加息预期的升温是触发此次暴跌的关键因素，投资者正在重新定价利率风险。

《西雅图时报》注意到，亚马逊和微软在此次抛售中表现相对较好，这表明市场并非全面看空科技股，而是对缺乏实际盈利支撑的纯AI概念公司失去信心。CNN援引分析师观点警告，如果就业数据继续疲软且通胀居高不下，市场可能面临更大的下行压力。

美国股市周五延续强劲涨势，标普500指数刷新历史新高，连续第六周收涨。这一轮上涨得益于超出预期的4月就业数据和美伊谈判取得进展的乐观信号。

就业数据超预期

尽管招聘速度有所放缓，但4月新增就业人数仍超过了分析师预期。这一数据表明劳动力市场依然稳健，为经济持续扩张提供了支撑。投资者将此解读为"软着陆"前景的信号——经济既不过热，也未出现衰退迹象。

伊朗协议预期提振市场

与此同时，美国和伊朗之间的和平谈判传来积极信号。尽管此前在霍尔木兹海峡发生了交火事件，但双方仍在考虑一份一页纸的和平协议框架。市场将地缘政治风险溢价视为下降趋势，推动了风险资产的上涨。

连续第六周上涨

标普500指数的六连涨是自去年以来的最长连胜纪录。科技股和周期股共同领涨，反映出投资者对经济增长和企业盈利的双重信心。

分析人士指出，当前市场情绪处于乐观区间，但投资者仍需关注通胀数据和美联储政策走向。如果通胀压力回升，可能会对当前的上涨势头构成挑战。

S&P 500 Hits Record on Jobs Beat and Iran Deal Hopes

US stocks extended their rally on Friday, with the S&P 500 index hitting a fresh all-time high and marking its sixth consecutive weekly gain. The rally was fueled by better-than-expected April jobs data and optimism surrounding US-Iran peace negotiations.

Jobs Report Exceeds Expectations

While hiring pace moderated, April nonfarm payrolls still surpassed analyst forecasts. The data suggests the labor market remains resilient, supporting the case for continued economic expansion without tipping into recession — the “soft landing” scenario investors have been pricing in.

Iran Deal Optimism

Despite a recent exchange of fire in the Strait of Hormuz, the US and Iran are reportedly considering a one-page peace framework. Markets interpreted this as a sign that geopolitical risk premiums are declining, boosting risk assets across the board.

Sixth Straight Weekly Gain

The S&P 500’s six-week winning streak is its longest run since last year. Both tech and cyclical sectors led the advance, reflecting investor confidence in both economic growth and corporate earnings.

Analysts note that while market sentiment is firmly in bullish territory, investors should keep an eye on inflation data and Federal Reserve policy signals. A resurgence in inflation pressures could challenge the current rally.

本周最重要的经济数据将是4月就业报告，预计将于本周五公布。分析人士指出，尽管伊朗局势带来不确定性，但就业市场数据仍将是判断美联储政策走向的关键指标。
