尽管高盛和巴克莱等银行最近的仓位指标显示，投资者对股市进一步上涨的前景仍然看涨，但一些市场 参与者正开始对在人工智能上的巨额投入能否带来回报持谨慎态度。 高盛集团策略师Peter Oppenheimer指出，现在就担心高歌猛进的美股科技股存在泡沫还为时过早。 Oppenheimer表示，科技巨头这轮破纪录的涨势一直伴随着强劲的盈利增长，而在过去的泡沫中，市场 主要是由投机情绪推动的。 Oppenheimer和他的团队在一份报告中写道："科技行业的估值正变得捉襟见肘，但尚未达到历史泡沫时 期的水平。" 尽管如此，这位策略师重申了他的建议，即投资者应寻求多元化投资，以避免美股涨势过于集中以及人 工智能领域竞争加剧所带来的风险。 包括英伟达、博通和微软在内的少数科技巨头已将美股推至历史新高，因为投资者押注于人工智能带来 的持续盈利增长和生产力提升。 在一份报告指出甲骨文公司云计算业务的利润率低于许多人的预期后，科技股权重较高的纳斯达克100 指数周二有所下滑。与此同时，彭博社汇编的数据显示，新闻报道中提及"科技"和"泡沫"的次数在近几 周大幅增加。 估值也水涨船高。纳斯达克100指数的预期市盈率为28倍，而其十年平 ...

智通财经APP获悉，高盛策略师 Peter Oppenheimer表示，现在就担心美国高科技股票出现泡沫还为时尚 早。他指出，科技股的创纪录上涨行情伴随着强劲的盈利增长，而在以往的泡沫时期，市场上涨主要是 由投机行为推动的。 Oppenheimer及其团队在一份报告中写道："科技行业的估值已经超出正常范围，但尚未达到与历史泡沫 时期相一致的水平。" 不过，这位策略师再次强调了他的建议，即投资者应进行多元化投资，以规避美国股市窄幅上涨所带来 的风险以及人工智能领域日益激烈的竞争。 包括英伟达(NVDA.US)、博通(AVGO.US)和微软(MSFT.US)在内的几家科技巨头推动了美国股市创下历 史新高，因为投资者看好其持续的盈利增长以及人工智能带来的生产效率提升。 尽管像高盛和巴克莱银行等金融机构近期发布的相关指标显示，投资者仍对股票进一步上涨的前景持乐 观态度，但一些市场参与者却对在人工智能领域大规模投入所带来的回报变得谨慎起来。 味着"这并非仅仅关乎科技领域的泡沫，而更多的是与低利率、全球储蓄率高以及长期经济周期等总体 状况有关"。 周二，以科技股为主的纳斯达克 100 指数下跌，此前有报道称，甲骨文(OR ...
