跟进：美股收盘分化定格 道指涨0.38%守住蓝筹阵地 标普纳指小跌、芯片股拖后腿 油价再涨能源板块创新高 债市因哥伦布日休市
哥伦布日的美股交易周一收盘定格，分化格局与午盘一致、尾盘没有反转。道琼斯工业平均指数收涨约198点、涨幅0.38%，报约51,853点，由蓝筹与防御板块托住；标普500指数微跌0.06%，报7,807.24点；纳斯达克综合指数跌0.44%，报约27,246点，纳斯达克100指数跌0.71%，是三大指数中跌幅最深的一个。美国债券市场周一因哥伦布日休市，10年期美债收益率停留在上周五的约5.24%，周二才有新的定价。
板块层面，能源是全场主角。胡塞武装周末袭击利雅得机场、乌克兰能源设施再遭打击，布伦特原油收涨约1.3%至每桶106.09美元，美国WTI原油涨约1.5%至93.28美元，标普500能源板块大涨约1.5%，收于近一个月来的首个新高。通信服务与必需消费等防御板块跟涨，金融股在财报周前夕走稳；另一端，科技与芯片股领跌：美光科技跌约3%，市场消化中国长鑫存储在存储芯片结构上的新进展消息；闪迪跌逾6%，费城半导体指数跌至三周低位。个股方面，赛富时获美银上调评级后涨约2%，微软涨约0.9%、盘中市值一度重返4万亿美元上方（为一年来首次），Meta随新款AI模型Muse Wonder发布走强。
这一天也恰逢本轮牛市的四周年——标普500自2022年10月12日的低点以来累计涨幅已超过120%。但让投资者不敢松口气的是接下来的日程：周二盘前，摩根大通、高盛、富国银行、花旗集团等大行以及强生、联合健康将发布三季度财报，财报季正式进入高潮；周三公布9月消费者价格指数（CPI），周四公布生产者价格指数（PPI）——在油价站上106美元、10年期收益率逼近24年高位的背景下，这两份通胀数据将直接决定美联储10月底议息会议前的市场定价。GSM午盘稿记录的分化只是过程，周一的收盘价把问题留给了财报与通胀：蓝筹的稳，能否扛住芯片与估值的双重压力，要看接下来72小时的数据。

Wall Street Closes Mixed: Dow +0.38% as Chips Drag Nasdaq Lower, Oil Lifts Energy to a Record; Bond Market Shut for Columbus Day
U.S. stocks closed mixed on Monday, October 12, finalizing the split seen at midday. The Dow Jones Industrial Average rose about 198 points, or 0.38%, to roughly 51,853, while the S&P 500 slipped 0.06% to 7,807.24 and the Nasdaq Composite fell 0.44% to about 27,246, with the Nasdaq 100 down 0.71%. The U.S. bond market was closed for Columbus Day, leaving the 10-year Treasury yield at Friday's roughly 5.24%. Energy led the market as Brent crude settled up about 1.3% at $106.09 a barrel and WTI gained about 1.5% to $93.28, sending the S&P 500 energy sector up about 1.5% to its first record high in nearly a month. Chip stocks lagged — Micron fell about 3% on news of progress by China's CXMT — while Salesforce rose about 2% on a Bank of America upgrade and Microsoft added about 0.9%, briefly topping a $4 trillion market value for the first time in a year. The session marked the bull market's fourth anniversary, with the S&P 500 up more than 120% since October 12, 2022. Attention now turns to Tuesday's bank earnings from JPMorgan, Goldman Sachs, Wells Fargo and Citigroup, Wednesday's CPI and Thursday's PPI.
