The theme holds that US equity index gains are being carried by a small group of megacap and AI-linked tech stocks while market breadth weakens, leaving indices exposed to a sharp fall if those leaders stumble. Most houses (52 of 55) support this risk view, with researchers pointing to record concentration, a median S&P 500 stock well below its 52-week high, and sizeable AI-related capex and debt. The main counterargument from a minority is that the AI investment boom continues to support headline performance, and only two houses argue against the theme.
Each house counts once: its newest view on the theme in the last 60 days. The counts are computed, not written by AI; the summary is AI-written from the houses’ views, without names.
