美国股指期货周二走势分化，原油价格小幅上涨，市场静待中期选举结果，与此同时，苹果加入了财报未能令投资者满意的大型科技公司行列。
US stock index futures were mixed on Tuesday as crude oil prices ticked up and markets awaited the midterm elections results, while Apple joined the list of Big Tech companies whose results failed to impress investors.
苹果在盘前交易中下跌4.5%，此前该公司警告称内存芯片成本将继续上升，将压低其假日季毛利率。人工智能驱动的分析软件供应商帕兰蒂尔科技预测，第四季度营收将高于预期，此前其第三季度业绩已超预期。然而，其股价却下跌了6.3%。
Apple fell 4.5% in premarket trading after the company warned the cost of memory chips would continue to rise, pressuring its holiday-quarter gross margin. AI-powered analytics software provider Palantir Technologies forecast revenue above estimates for the last three months of the year after topping third-quarter expectations. Its shares, however, fell 6.3%.
纳斯达克100指数周一收盘较历史收盘高位下跌逾10%，确认这只科技股占比极高的指数已进入回调区间，因为投资者对大型科技公司飙升的人工智能支出及缺乏足够回报证据日益警惕。最近几家科技公司还动用债券市场为巨额人工智能投资融资，加剧了人们的担忧，即随着借贷成本上升，债务融资的支出将更难以被证明合理。
The Nasdaq-100 closed more than 10% lower from its all-time closing high on Monday, confirming that the tech-heavy index has entered a correction as investors grow wary of Big Tech's soaring AI spending and little evidence of adequate returns. Several tech companies have also tapped the bond market to finance big AI investments recently, amplifying concerns that debt-funded spending will become harder to justify as borrowing costs rise.

美国东部时间上午5点06分，道琼斯E-mini期货下跌219点，跌幅0.42%；标普500 E-mini期货上涨1.5点，涨幅0.02%；纳斯达克100 E-mini期货上涨130.5点，涨幅0.46%。大多数芯片股上涨帮助抵消了部分科技股的跌幅。英伟达上涨1.6%，此前已连跌四个交易日。在英伟达近期大幅下跌后，苹果上周超越这家芯片设计商，成为全球市值最高的公司。
ET, Dow E-minis were down 219 points, or 0.42%, and S&P 500 E-minis were up 1.5 points, or 0.02%. Nasdaq 100 E-minis were up 130.5 points, or 0.46%. Helping offset some losses among tech stocks was a rise in most chip stocks. Nvidia climbed 1.6% after falling for the last four sessions. Following the recent heavy losses in Nvidia, Apple surpassed the chip designer to become the world's most valuable company last week.
AMD 在盘后财报发布前上涨 2.8%，Marvell Technology（美满电子）和 Intel（英特尔）也走高。
AMD gained 2.8% ahead of its quarterly earnings due after the bell, while Marvell Technology and Intel were also moving higher.
等待中期选举结果 美国选民将在周二的中期选举中，对唐纳德·特朗普总统第二任期的前两年做出裁决。民调和非党派分析师倾向于认为民主党将从共和党手中夺回众议院控制权，而参议院控制权仍不确定。
MIDTERMS RESULTS AWAITED American voters will deliver a verdict on the first two years of President Donald Trump's second term in Tuesday's midterm elections, with polls and nonpartisan analysts favoring Democrats to wrest the House from Republicans, while the control of the Senate remains uncertain.
“围绕政府支出和赤字的担忧持续升温，加剧了市场波动，”法国兴业银行分析师在报告中表示。
"Concerns around government spending and deficits have continued to build, contributing to market volatility," Societe Generale analysts said in a note.
“然而，任何有意义的财政扩张仍需要广泛谈判，且随着民主党有望控制众议院，立法背景可能变得更加僵局化。”摩根士丹利分析师本周早些时候在报告中表示，选举应有助于消除一个主要的市场压制因素。他们相信，始于 6 月的美国股市回调已进入“最后阶段”。
"However, any meaningful fiscal expansion would still require extensive negotiation, and with Democrats likely to gain control of the House, the legislative backdrop could become more gridlocked." Morgan Stanley analysts said in a note earlier this week that the elections should help remove a major market overhang. They believes the US market correction that began in June was in its "final innings".
另一个风险因素可能是美国在中期选举后重启对伊朗的打击，特朗普在最近几周对此有过暗示。摩根大通分析师本周早些时候在报告中表示，他们将因地缘政治紧张局势导致的任何市场回调视为买入机会。不过，当记者周一询问他是否考虑在中期选举后打击伊朗时，特朗普表示“否。”
Another risk factor could be the US renewing attacks on Iran after the midterms, something that Trump has hinted about in recent weeks. J.P. Morgan analysts said in a note earlier this week that they view any dip in the markets, due to geopolitical tensions, as a buying opportunity. However, when asked by reporters on Monday if he was considering striking Iran after the midterms, Trump said "no."
原油价格周二上涨，此前一交易日大幅下跌。一名伊朗官员称结束战争的协议尚远，而美国打击了伊朗的格什姆岛。与此同时，财报季仍在全面展开。制药商 Pfizer（辉瑞）、农业企业 Archer-Daniels-Midland（阿彻·丹尼尔斯·米德兰）和炼油商 Marathon Petroleum（马拉松石油）将在开盘前发布财报。
Crude oil prices rose on Tuesday after slumping in the previous session, as an Iranian official said a deal to end the war was far off, while the United States struck Iran's Qeshm Island. Meanwhile, the earnings season remained in full swing. Drugmaker Pfizer, agribusiness Archer-Daniels-Midland and oil refiner Marathon Petroleum were set to report before the bell.
