标普500创新高背后现极端分化,美银警告美股市场或接近泡沫末期

Odaily星球日报讯 标普 500 指数在 5 月最后一个交易日创下收盘历史新高,但成分股中仅有少数个股同步刷新历史高点,且多数集中在人工智能相关板块,引发市场对行情结构性失衡的关注。分析人士指出,尽管指数持续创新高,但上涨集中于少数权重科技股,市场分化程度接近历史极端水平,可能意味着潜在风险正在累积。
数据显示,上周五标普 500 仅有 20 只成分股创出历史新高,其中仅 7 只与人工智能无直接关联。美国银行策略师 Michael Hartnett 指出,这一现象与 2000 年互联网泡沫顶峰时期高度相似,当时同样仅有约 20 只个股创下新高。
Hartnett 在最新报告中警告,当前市场投机情绪仍在延续,但在高利率与全球央行紧缩政策背景下,行情拐点可能正在临近。他建议投资者逐步转向防御型资产配置。
5 月美股上涨主要由半导体板块推动,美光科技上涨 87.8%,超威半导体上涨 45.6%,三星上涨 43%,SK 海力士上涨 81%,推动纳斯达克指数在 4 至 5 月累计上涨 25%,创下二十余年来最佳两月表现。(金十)
