纽约：美国股市周四（10月22日）大幅下跌，纳斯达克指数录得自6月初以来最大单日跌幅，一批备受瞩目的财报引发了市场对人工智能支出竞赛的新担忧。
NEW YORK: US stocks tumbled on Thursday (Oct 22) and the Nasdaq posted its steepest daily drop since early June as a batch of high-profile earnings reports ignited fresh fears about the AI spending race.
标普500指数深陷跌势。但以科技股为主的纳斯达克指数在一系列备受瞩目的AI相关财报发布后跌幅更大，拖累于芯片股，下跌2.6%。蓝筹股道琼斯指数在收盘前几分钟勉强录得微幅上涨。
The S&P 500 ended deep in negative territory. But the tech-laden Nasdaq, dragged down by microchips, suffered a steeper loss, falling 2.6 per cent in the wake of a spate of high-profile AI-related earnings results. The blue-chip Dow eked out a nominal gain minutes before the closing bell.
Meta Platforms的业绩超出分析师预期，但其股价下跌7.0%，因这家Facebook母公司因AI相关支出录得十多年来首次现金流出，并宣布计划以二比一拆股方式发行无投票权股份，以筹集资金用于这项新兴技术的支出。
Meta Platforms' results beat analyst expectations, but its stock slid 7.0 per cent as the Facebook parent posted its first cash outflow in more than a decade due to its AI-related expenditures and announced plans to issue non-voting shares in a two-for-one split to raise capital to spend on the nascent technology.

“今天是华尔街的美好一天，”伊利诺伊州埃尔姆赫斯特Murphy & Sylvest公司的高级财富顾问兼市场策略师保罗·诺尔特（Paul Nolte）表示。“目前市场上真正受损的只有科技板块，此前它一直是市场的‘宠儿’，直到大约6月份为止。”
"It's a wonderful day on Wall Street," said Paul Nolte, senior wealth adviser & market strategist at Murphy & Sylvest in Elmhurst, Illinois. "The only part of the market that is really suffering here is technology, which has been the golden child of the markets up until about June."
诺尔特补充道：“投资者开始意识到AI（人工智能）故事中存在一些漏洞。由于指数对科技板块的权重极高，这正在影响指数表现。”在地缘政治舞台上，伊朗支持的胡塞武装对沙特目标发动新一轮袭击，推高国际油价至五个月高位。投资者担心中东持续动荡可能导致通胀居高不下，迫使美联储继续加息。
"Investors are starting to realize that there are some holes in the AI story," Nolte added. "And that's having an impact on the indices because they're so heavily weighted toward technology." On the geopolitical stage, Iran-backed Houthis launched new strikes against Saudi targets, sending crude prices to a five-month high. Investors worried that ongoing Middle East strife could keep inflation hot and force the US Federal Reserve to keep raising interest rates.

Data from the Labour Department showed initial claims for unemployment benefits kept drifting along near multi-decade lows. Signs of labor market stability will allow the Fed to focus on fighting inflation. Financial markets are currently pricing in the probability that the central bank will raise its policy rate by another 25 basis points before year-end.
