历史上四轮科技股泡沫：回顾与启示 20260226 摘要 当前美股和 A 股市场存在由 AI 驱动的科技股热潮，但估值和集中度是主 要问题。标普 500 远期估值显著高于过去十年中位数，美股前十大公司 市值占比虽略有回落，但仍处高位，市场担忧情绪集中。 头部科技公司，尤其是云计算和云服务公司，资本开支显著上升。预计 "七姐妹"加博通的 Kubernetes 相关投入规模将从 2023 年的 1,675 亿美元增至 2028 年的 6,700 亿美元左右，对现金流形成侵蚀，并制约 通过回购提升 EPS 的能力。 历史上四轮科技股泡沫（英国运河热潮、铁路热潮、"咆哮 20 年代"、 科网泡沫）的研究框架包括触发背景、金融环境、一级市场扩张、二级 市场表现及破灭机制的复盘，旨在总结普遍规律，并与当前 AI 行情对比。 英国运河热潮受益于工业革命带来的运输需求激增。早期运河项目回报 可观，例如布里奇沃特公爵修建的运河形成垄断优势，并通过通行费获 得收益，伯明翰运河最初 5 年股息率约 3.9%，后 5 年升至 10.6%。 英国运河泡沫高峰期在 1,792-1,793 年，议会通过大量运河法案，投机 资金涌入，运河股 ...
