资深策略师Ed Yardeni表示，在经历了自去年纪录高点以来的回调后，对于愿意进行长期布局的投资者而言，科技股已回到具有吸引力的水平。由于围绕人工智能对软件业务影响的不确定性，加之伊朗战争带来的影响，信息技术板块股价自10月创下历史收盘新高以来已下跌了13%。在此期间，对该板块的盈利预期加速上修，推动其本益比达到20.6倍，接近标普500指数的19.6倍。 信息技术板块与通信服务板块合计占标普500指数市值的大部分。Yardeni表示，这一占比已超过互联网泡沫时期的峰值。尽管这种对比可能令部分投资者感到不安，但与26年前相比，如今市场的高集中度有更多盈利支撑。如今，这两个行业的预期盈利占比为42.0%，仅比市值占比高出1.6个百分点；在互联网泡沫高峰期，市值占比和盈利占比之间的差距超过15个百分点。
