美国股市在下午的交易中挣扎着寻找方向，因为投资者权衡了即将到来的关税和经济不确定性的潜在影响。标准普尔500指数徘徊在平线附近，道琼斯指数下跌54点，纳斯达克指数微涨0.1%。周一的反弹，在缩小关税措施的希望推动下，失去了动力，因为特朗普总统表示，一些国家可能会获得将于4月2日生效的互惠关税豁免，同时也暗示对药品和汽车征收新的关税。特斯拉在周一飙升12%后出现波动，英伟达下跌0.7%。KB Home在下调销售预期后下跌5%，UniFirst在Cintas结束收购谈判后下跌12%。投资者还消化了消费者信心的急剧下降，降至四年低点，未来预期降至12年来的最低水平。与此同时，交易员加大了对美联储2025年降息的押注，但市场策略师对股市前景仍存在分歧。

US stocks struggled for direction in the afternoon session as investors weighed the potential impact of upcoming tariffs and economic uncertainties. The S&P 500 hovered near the flatline, while the Dow Jones lost 54 points, and the Nasdaq edged up 0.1%. Monday’s rally, driven by hopes of narrower tariff measures, lost steam as President Trump suggested some countries could receive exemptions from reciprocal duties set to take effect on April 2, while also hinting at fresh tariffs on pharmaceuticals and autos. Tesla wavered after surging 12% on Monday, Nvidia fell 0.7%. KB Home sank 5% after cutting its sales forecast and UniFirst tumbled 12% after Cintas ended acquisition talks. Investors also digested a sharp decline in consumer confidence, which fell to a four-year low, with future expectations dropping to the weakest level in 12 years. Meanwhile, traders increased bets on Federal Reserve rate cuts in 2025, but market strategists remained split on the outlook for equities.
