美股收盘：标普500指数跌1.1%创7月以来最差单日 科技股领跌、美联储褐皮书带滞胀色彩
美国股市10月14日收盘下跌。道琼斯工业平均指数下跌48点，跌幅0.1%；标普500指数下跌1.1%；纳斯达克综合指数下跌1.9%。据《巴伦周刊》报道，标普500与纳指均创下7月以来最差单日表现，科技股领跌，追踪半导体板块的交易所交易基金连续第七个交易日下跌。
当天公布的9月消费者价格指数（CPI）是触发抛售的主要因素：CPI同比上涨3.7%，高于市场预期的3.6%；剔除食品与能源的核心CPI同比上涨2.6%，同样高于预期。数据公布后，债券收益率一度急升，交易员对美联储本月晚些时候加息的押注随之升温。芝加哥商品交易所FedWatch工具显示，交易员预计美联储在10月28日会议上加息的概率约为37%，高于数据公布前的约22%。
美联储当天下午发布的经济景况褐皮书也被市场密切解读。罗森伯格研究公司的分析师指出，这份报告带有「滞胀色彩」：通胀仍是隐忧，而薪资增速与9月相比变化不大，劳动力市场情绪整体偏弱，对鹰派而言缺乏有力论据。10年期美国国债收益率盘中一度升至5.33%，临近收盘回落至约5.20%。
板块与个股方面，医疗保健板块上涨1.8%，为标普500十一大板块中表现最佳者，消费必需品板块同样走高，帮助道指相对抗跌。银行股三季度财报分化：摩根士丹利利润超出预期，得益于股票交易业务强劲；美国银行的业绩不及预期并受到罚款问题拖累。市场接下来将关注10月15日公布的9月生产者价格指数（PPI）。
U.S. Stocks Close Lower: S&P 500 Falls 1.1% in Its Worst Day Since July as Tech Slides and the Fed's Beige Book Carries a Stagflationary Flavor
U.S. stocks closed lower on Wednesday, October 14. The Dow Jones Industrial Average fell 48 points, or 0.1%; the S&P 500 fell 1.1%; and the Nasdaq Composite fell 1.9%. According to Barron's, the S&P 500 and the Nasdaq both marked their worst day since July, with technology stocks leading the decline and a major semiconductor ETF falling for a seventh straight session.
The September Consumer Price Index was the main trigger. CPI rose 3.7% from a year earlier, above the 3.6% economists had expected, while core CPI, excluding food and energy, rose 2.6%, also hotter than forecast. Bond yields spiked after the release as traders lifted bets on a Federal Reserve rate increase later this month. CME FedWatch showed traders pricing roughly a 37% chance of a hike at the October 28 meeting, up from about 22% before the data.
Markets also weighed the Fed's Beige Book, released Wednesday afternoon. An analyst at Rosenberg Research wrote that the report had a "stagflationary flavor": inflation remains a concern, wage growth appears little changed from September, and overall labor market sentiment is weaker. The 10-year Treasury yield, which had soared to 5.33% after the CPI report, pulled back to around 5.20% near the close.
Healthcare was the best-performing of the S&P 500's 11 sectors, rising 1.8%, and consumer staples also gained, cushioning the Dow. Bank earnings diverged: Morgan Stanley beat third-quarter profit estimates on strong equity trading, while Bank of America's lackluster results and a large fine weighed on its shares. Investors next turn to the September Producer Price Index, due Thursday morning.
