美股市场走势分化：美联储政策公布前夕，道指创历史新高而科技股下跌

周二，华尔街经历了显著的市场分化，投资者正从高涨的科技股转向更为传统的板块。尽管道琼斯工业平均指数连续第二个创下收盘历史新高，但随着市场参与者为即将到来的美联储政策更新做准备，纳斯达克指数和标普500指数均出现回落。

板块轮动：科技股回调遇上工业股上涨

本次交易时段的特点是投资者情绪发生了明显转变。在周一经历了一轮强劲反弹（纳斯达克指数大涨超过3%，标普500指数上涨1.65%）之后，交易员似乎正在从估值过高的科技公司中获利了结。这种降温效应在芯片股中尤为明显，在经历了连续三天的价格飙升后，芯片股面临大幅下跌。

随着以科技股为主的指数走弱，资金流向了对经济敏感的板块。标普500指数下跌41.85点（0.55%），收于7,512.44点；纳斯达克综合指数下跌301.13点（1.15%），收于26,382.81点。相比之下，在金融和工业板块走强的推动下，道琼斯工业平均指数上涨345.54点（0.67%），创下52,016.57点的收盘历史新高。

地缘政治及其对能源市场的影响

油价在市场波动中发挥了重要作用，下跌了5.8%。这一跌势受到有关美伊临时协议细节披露的推动。该协议旨在延长停火并重新开放霍尔木兹海峡，缓解了此前推高能源价格的地缘政治紧张局势。

伊朗在签署协议后恢复石油销售的可能性，缓解了市场对供应中断的即时担忧。能源价格的降温对美联储来说是一个关键因素，因为从历史上看，高油价会导致“粘性”通胀，从而使中央银行的利率调整路径变得更加复杂。

期待美联储的决定

The primary focus for global investors remains the Federal Reserve's policy update scheduled for Wednesday. Market consensus suggests that the Fed will likely hold interest rates within the current 3.50% to 3.75% range. However, all eyes are on new Fed Chairman Kevin Warsh, as his commentary on inflation, unemployment, and the broader economic outlook will dictate future market directions.

While many traders expect rates to remain steady for much of the year, uncertainty remains regarding the year-end. According to the CME Group's FedWatch tool, there is currently a roughly 42% probability of a 25-basis-point rate hike in December.
