与人工智能（AI）相关的股票在周四大幅下跌，导致全球股市普遍走低。与此同时，由于投资者担忧伊朗相关战争对全球能源供应的影响，油价攀升至五个月来的最高水平。截至美国东部时间周四上午10点45分，标准普尔500指数下跌了1.4%，纳斯达克综合指数下跌了2.2%；道琼斯工业平均指数则下跌了0.6%（跌幅为295点）。纳斯达克指数的较大跌幅反映了科技股所面临的压力，而科技行业以外的公司表现相对较好。
Stocks linked to artificial intelligence (AI) fell sharply on Thursday, dragging stock markets across the world lower. At the same time, oil prices climbed to their highest level in five months as investors worried about the war involving Iran and its impact on global energy supplies. The S&P 500 fell 1.4%, while the Nasdaq Composite dropped 2.2% as of 10:45 a.m. Eastern time on Thursday. The Dow Jones Industrial Average fell by a smaller 0.6%, or 295 points.

AI股票下跌的原因：高成本与支出担忧由于投资者担心建设数据中心和购买AI芯片的高成本，与AI相关的股票表现不稳定。企业需要投入大量资金来发展其AI业务，而借贷成本也有所上升。此外，投资者还认为，尽管这些公司持续报告业务增长，但AI股票的价格可能已经过高。
Companies need to spend large amounts of money to expand their AI businesses, and borrowing has become more expensive. Investors are also concerned that AI stocks may have become too expensive after years of strong gains, even as companies continue to report business growth.
具体公司情况：
Lam Research, which makes equipment and provides services used in semiconductor manufacturing, reported higher revenue and profit for the summer quarter.
Lam Research：这家公司生产用于半导体制造的设备并提供相关服务。其夏季季度的收入和利润均略高于分析师的预期，但股价仍下跌了9.7%，原因是其对2026年最后三个月的利润预测低于预期（低于其预测范围的中值）。
Both figures were slightly better than analysts had expected. However, its shares fell 9.7% because its profit forecast for the final three months of 2026 was weaker than expected at the midpoint of its projected range, according to AP.P&G raises 2027 cost outlook to $1.4 billion as higher oil prices squeeze profitsThe company's shares had risen 52.4% so far in 2026 before Thursday's fall.
P&G：由于油价上涨导致利润压力增加，该公司将2027年的成本预测上调至14亿美元。截至周四，P&G的股价在2026年已上涨了52.4%，这一涨幅几乎是标准普尔500指数同期涨幅的四倍。这种强劲的上涨让投资者产生了较高的预期，因此当公司的未来利润前景令投资者失望时，其股价便容易下跌。
This was nearly four times the gain recorded by the S&P 500 over the same period. The strong rise had created high expectations among investors, leaving the stock vulnerable to a fall when the company's future profit outlook disappointed them.
其他公司情况：
Meta Platforms（Facebook和Instagram的母公司）的股价下跌了6.4%。
Meta stock falls 6.4% despite higher revenueMeta Platforms, the parent company of Facebook and Instagram, saw its shares fall 6.4%.
公司报告称最新季度的收入强于分析师预期，但利润未达预期。美联社称，Meta 正在推进其 Muse AI 代理，并扩大其人工智能业务。Meta 表示正创建一种新类别的股票，以为其 AI 投资和其他支出筹集资金。此举正值公司持续在人工智能上投入之际，尽管投资者对开发和扩展 AI 技术的成本日益担忧。
The company reported stronger revenue for the latest quarter than analysts had expected, but its profit fell short of expectations. Meta is also pushing ahead with its Muse AI agent as it expands its artificial intelligence business, according to AP. Meta said it was creating a new class of stock to raise money for its AI investments and other expenses. The move comes as the company continues to spend on artificial intelligence, even though investors are becoming more concerned about the costs of developing and expanding AI technology.
特斯拉股价在周四抹去早盘的跌幅，微升 0.1%。这家电动汽车制造商报告称夏季季度利润高于分析师预期。然而，其收入低于预测，显示该公司本季度业绩喜忧参半。
Tesla shares erased an early decline and rose 0.1% on Thursday. The electric vehicle maker reported higher summer-quarter profit than analysts had expected. However, its revenue was weaker than forecast, showing that the company had mixed results for the quarter.
英伟达股价下跌，AI 抛售蔓延。全球领先的 AI 芯片制造商英伟达的股价下跌 3.8%，因投资者抛售科技股。英伟达是华尔街市值最大的公司，其股价对标普 500 指数影响重大。美联社称，其跌幅成为周四指数下跌的主要原因之一。

Nvidia shares drop as AI sell-off spreadsNvidia, the world's leading maker of AI chips, saw its shares fall 3.8% as investors sold technology stocks. Nvidia is the largest company on Wall Street by total market value, so its share price has a major influence on the S&P 500. Its decline became one of the biggest reasons for the index's fall on Thursday, according to AP.AI-powered hackers exploit PHP flaw as Europe takes government websites offline; NSA warns of cyberattack risksCoreWeave shares dropped 7.1% as concerns about the company's debt continued to worry investors.
CoreWeave 股价下跌 7.1%，因公司债务问题持续令投资者担忧。该公司借款购买英伟达的 AI 芯片，并通过云服务向客户租赁计算能力。其股价近期波动尤为剧烈，过去两天分别在约 4% 的涨跌之间来回波动。

亚洲市场因科技股下跌而暴跌。AI 与科技股的抛售先在亚洲启动，随后蔓延至其他市场。韩国 Kospi 指数下跌 3.5%，香港恒生指数下跌 3%，日本日经 225 指数下跌 2.7%。
Asian markets tumble as tech stocks fallThe sell-off in AI and technology stocks began in Asia before spreading to other markets. South Korea's Kospi fell 3.5%, Hong Kong's Hang Seng Index dropped 3%, and Japan's Nikkei 225 declined 2.7%.
亚洲市场受冲击尤为严重，因为其股指在人工智能和其他科技公司方面持有大量仓位，据美联社报道。国际油价因伊朗战事担忧升至五个月高点国际基准布伦特原油上涨2.6%，至每桶111.60美元，触及五个月来最高水平。10月份以来，油价在每桶97美元至112美元区间波动，交易员试图评估涉及伊朗的战争何时能让全球能源供应恢复正常。

Oil prices hit five-month high amid Iran war fearsBrent crude oil, the international benchmark, climbed 2.6% to $111.60 a barrel after touching its highest level in five months. Oil prices have moved between $97 and $112 a barrel during October as traders try to assess when the war involving Iran will allow global energy supplies to return to normal.
投资者担心涉及伊朗的冲突可能扰乱能源供应，阻碍全球石油行业恢复正常。油价上涨加剧了对企业成本和整体经济成本的担忧。据美联社报道，科技股下跌与油价上涨的双重打击拖累了全球股市。法国股市下跌，债务担忧加剧法国CAC 40指数下跌1%，录得欧洲股市中跌幅较大的表现之一。该指数科技股权重低于美股和亚洲市场，但因法国政府债券收益率再度上升而承压。投资者担忧法国政府债务规模庞大且预算紧张。
Investors are worried that the conflict involving Iran could disrupt energy supplies and prevent the global oil industry from returning to normal. The rise in oil prices adds to concerns about costs for businesses and the wider economy. The combination of falling technology shares and rising oil prices weighed on stock markets worldwide, according to AP. French stocks fall as debt worries growFrance's CAC 40 index fell 1%, recording one of the sharper declines among European stock markets. The index has fewer technology stocks than US and Asian markets, but it came under pressure as French government bond yields rose again. Investors are worried about France's large government debt and strained budget.
法国各地爆发暴力抗议，增加了政府增加开支的压力。额外开支可能加剧该国债务问题，加深投资者对政府财政状况的担忧，推高投资者持有法国政府债券所要求的收益率。美国债券收益率下跌，投资者寻求避险对政府高债务的担忧波及包括美国在内的许多发达经济体。据美联社报道，在美国，高通胀、经济强劲迹象及其他经济压力推高政府债券收益率至数十年来未见水平。
Violent protests across France have increased pressure on the government to spend more money. Additional spending could make the country's debt problem worse, adding to investor concerns about the government's finances and pushing up the yields demanded by investors holding French government bonds.US bond yields fall as investors seek safetyConcerns about high government debt are affecting many developed economies, including the United States. In the US, high inflation, signs of a strong economy and other economic pressures have helped push government bond yields to levels not seen in decades, according to AP.
尽管对美国债务的广泛担忧依然存在，但周四美国国债收益率下跌，因投资者转向美国政府债券。
Despite the wider concerns about US debt, Treasury yields fell on Thursday as investors moved towards US government bonds.
这一举动表明，一些投资者正在寻找更安全的资金去处，而人工智能股票和其他科技股正在下跌。周四，美国10年期国债收益率降至5.01%，低于周三晚间的5.13%，也低于10月初的5.30%以上。这是债券市场的一个显著变动。不过，据美联社报道，收益率仍远高于涉及伊朗的战争爆发前的3.97%水平。美国就业数据指向经济强劲另一份报告显示，上周申请失业救济的美国工人减少。这表明全美裁员人数可能保持低位，美国就业市场的表现可能好于经济学家的预期。
The move suggested that some investors were looking for safer places to put their money while AI stocks and other technology shares were falling. The yield on the 10-year US Treasury fell to 5.01% on Thursday, down from 5.13% late Wednesday and more than 5.30% earlier in October. The fall was a notable move in the bond market. However, the yield remained well above its 3.97% level before the war involving Iran, according to AP.US jobs data points to a strong economyA separate report showed that fewer US workers applied for unemployment benefits last week. This suggests that layoffs may remain low across the country and that the US job market could be holding up better than economists expected.
美国经济保持足够强劲，帮助许多公司增加利润。更好的盈利推动美国股市在10月初升至历史高位，尽管市场对通胀、政府债务以及涉及伊朗的战争存有担忧。
The US economy has remained strong enough to help many companies increase their profits. Better earnings helped push the US stock market to a record high earlier in October, despite concerns about inflation, government debt and the war involving Iran.
尽管标普500指数周四下跌，但该指数内的大多数个股实际上上涨了。几家公司的涨幅不足以抵消主要科技股的跌幅，因为这些科技股市值巨大，对指数影响更大。宝洁股价因业绩强劲大涨5.8%宝洁公司（P&G），即佳洁士、玉兰油和欧乐-B等品牌背后的公司，是报告夏季季度利润超出预期的企业之一。其股价周四上涨5.8%，帮助缩窄了大盘的跌幅。
Although the S&P 500 declined on Thursday, most of the stocks within the index actually rose. Gains in several companies were not enough to offset the losses in major technology stocks, which have a greater influence on the index because of their large market values.P&G shares jump 5.8% after strong resultsProcter & Gamble (P&G), the company behind brands such as Crest, Olay and Oral-B, was among the businesses that reported better-than-expected summer-quarter profits. Its shares rose 5.8% on Thursday, helping limit the broader market's losses.P&G CEO Shailesh Jejurikar said the company expects geopolitical and economic challenges to continue.
宝洁首席执行官Shailesh Jejurikar表示，公司预计地缘政治和经济挑战将持续。不过，据美联社报道，公司维持全年营收增长、利润增长及其他财务指标预测不变。
However, the company kept its forecasts for full-year revenue growth, profit growth and other financial measures unchanged, according to AP.
国防企业洛克希德·马丁和运输企业CSX等也是报告夏季季度利润超出分析师预期的公司之一。
Defence company Lockheed Martin and transport company CSX were among the other businesses that joined the list of companies reporting summer-quarter profits above analysts' expectations.
这些公司的股价上涨，加上宝洁（P&G）的业绩表现，共同支撑了股市的部分表现；与此同时，科技类股票的股价却出现了下跌。周四的市场走势凸显了以下两种情况之间的差异：一方面是那些面临高运营成本和估值问题的科技股；另一方面则是那些报告了强劲盈利表现的其他企业。据美联社（AP）报道，虽然美国经济的整体表现较为强劲，但油价上涨、对伊朗战争的担忧、政府债务问题以及人工智能（AI）相关支出的不确定性，都让投资者保持谨慎态度。
Gains in these companies, along with P&G, helped support parts of the stock market as technology shares fell. Thursday's market movement showed the difference between technology stocks facing high spending costs and valuation concerns, and other businesses reporting strong profits. While a relatively strong US economy has supported company earnings, rising oil prices, fears about the Iran war, government debt and uncertainty over AI spending have kept investors cautious, according to AP.
