美国股市周三大幅下跌，科技股领跌，因对美国即将征收关税的担忧日益加剧。标准普尔500指数下跌1.1%，纳斯达克100指数下跌2%，结束了为期三天的反弹，而道琼斯指数下跌134点。英伟达和特斯拉股价暴跌5.5%以上，而Meta、亚马逊和Alphabet等主要科技公司股价下跌2%以上。在有报道称特朗普总统将于美国东部时间下午4点对汽车进口征收新关税后，汽车股也走弱，通用汽车股价下跌3%。围绕这些关税的范围和影响的不确定性加剧了市场波动，引发了人们对报复和更广泛经济影响的担忧。与此同时，随着美国威胁对购买委内瑞拉原油的国家征收关税，油价攀升，能源股上涨。投资者现在等待周五的个人消费支出通胀报告，这是美联储下一个政策决定的关键因素。

US stocks fell sharply on Wednesday, as tech stocks led a broad selloff amid mounting concerns over impending US tariffs. The S&P 500 declined 1.1% and the Nasdaq 100 dropped 2%, ending a three-day rally, while the Dow Jones lost 134 points. Nvidia and Tesla plunged more than 5.5%, while major tech firms like Meta, Amazon, and Alphabet slid over 2%. Auto stocks also weakened after reports that President Trump would introduce new tariffs on vehicle imports at 4 p.m. ET, with General Motors slipping 3%. Uncertainty surrounding the scope and impact of these tariffs has fueled market volatility, raising fears of retaliation and broader economic fallout. Meanwhile, energy stocks gained as oil prices climbed following US threats of tariffs on nations buying Venezuelan crude. Investors now await Friday’s PCE inflation report, a key factor in the Federal Reserve’s next policy decision.

美国股市在下午大幅下跌，有望迎来为期三天的反弹，因为新的关税担忧和科技股势头的减弱扰乱了市场。标准普尔500指数下跌1.1%，纳斯达克100指数下跌1.7%，道琼斯指数抹去早盘涨幅，下跌100点。超级股大幅下跌，英伟达暴跌6%，特斯拉（-5.7%）、亚马逊（-2.3%）和Alphabet（-2.4%）也下跌。白宫宣布特朗普总统将于下午4点公布新的汽车关税后，抛售加剧，通用汽车、福特和Stellantis的股价下跌。这一消息发布之前，预计下周将出台更广泛的贸易措施，加剧了人们对长期经济不确定性的担忧。投资者情绪仍然脆弱，尤其是在美联储官员阿尔贝托·穆萨勒姆警告关税驱动的通货膨胀可能会减缓2%目标的进展之后。国会预算办公室警告称，财政部最早可能在8月面临付款违约，这增加了压力。

US stocks tumbled in the afternoon session, on track to snapp a three-day rally, as renewed tariff concerns and fading tech momentum rattled markets. The S&P 500 slid 1.1%, the Nasdaq 100 dropped 1.7%, and the Dow Jones erased early gains to trade 100 points lower. Megacap stocks saw sharp declines, with Nvidia plunging 6% and Tesla (-5.7%), Amazon (-2.3%), and Alphabet (-2.4%) also falling. Selling intensified after the White House announced President Trump would unveil new auto tariffs at 4 p.m., sending shares of General Motors, Ford, and Stellantis lower. The news comes ahead of a broader wave of trade measures expected next week, fueling concerns over prolonged economic uncertainty. Investor sentiment remained fragile, especially after Fed official Alberto Musalem warned that tariff-driven inflation could slow progress toward the 2% target. Adding to the pressure, the Congressional Budget Office cautioned that the Treasury could face a payment default as soon as August.
