标普500指数周五几乎持平，尽管人们对人工智能交易可行性的担忧依然存在，但美联储本月将维持利率不变的迹象提振了投资者信心。

截至纽约时间上午9点56分，该股票基准指数下跌幅度不足0.1%。此前，美联储主席凯文·沃什在国际货币基金组织年会上发表讲话，并未打消市场对美联储本月底将维持利率不变的预期。
The stocks benchmark was down less than 0.1% as of 9:56 a.m. in New York, after Federal Reserve Chair Kevin Warsh — speaking at the International Monetary Fund’s annual meeting — did not dispel market expectations that the central bank will keep rates unchanged at the end of this month.

“美联储主席沃什昨晚在国际货币基金组织的讲话加强了对10月份按兵不动的预期，”摩根大通公司全球市场情报主管安德鲁·泰勒写道，“我们仍然专注于选择性的回调买入机会。”投资者削减了对美联储10月27日至28日政策会议上加息的押注。在沃什讲话前，加息赔率徘徊在27%左右，其讲话后跌至15%以下。
“Fed Chair Warsh’s remarks at the IMF last night strengthened expectations of an October hold,” wrote Andrew Tyler, global head of global market intelligence at JPMorgan Chase & Co, “We remain focused on selective dip-buying opportunities.”Investors pared their bets for a rate hike at the central bank’s Oct. 27-28 policy gathering. The odds, which were hovering around 27% before Warsh spoke, dropped below 15% following his remarks.
本周，标普500指数下跌0.8%，此前在过去三周中有两周录得涨幅，而纳斯达克100指数下跌超过3.5%，有望终结四周连涨。尽管主要美国股指本周面临周度跌幅，但标普500指数仅比本月早些时候创下的历史收盘高点低1%。

由于市场担忧人工智能行业的繁荣能持续多久，相关股票走势仍反复震荡。当前华尔街面临的压力很大程度上源于全球债券收益率正处于近二十年来的高位水平，这导致融资成本上升，也让人们开始担忧人工智能领域的支出能否继续保持强劲势头。由于许多科技公司的估值基于未来数年的预期盈利水平，它们对利率上升尤为敏感。
AI stocks keep swinging on worries about how much longer their boom will last. Much of the pressure on Wall Street stems from global bond yields hovering near their highest level in two decades, making borrowing money more expensive and spurring worries about how resilient AI spending can remain. Tech companies are particularly susceptible to rising rates as many of them are valued on projected profits delivered years in the future.
不过，本周财报季正式拉开帷幕，多家企业仍交出了亮眼的盈利成绩。正因如此，即便面临高通胀与利率上升的双重压力，美国股市依然保持平稳。铝业巨头美国铝业公司股价大涨4.1%，该公司公布的第三季度调整后盈利数据优于市场预期，这主要得益于铝产量与价格的双双提升。
