Summary
Capital Economics warns that the recent shift in US equities could signal a stock market bubble will burst in 2027, leading to years of upheaval in leadership across major indices. The firm’s chief markets economist, John Higgins, notes that the outperformance of small-cap, value, and defensive stocks relative to large-cap, growth, and cyclical names echoes patterns seen in the late stages of the dot-com boom. Higgins argues that the latest rotation in stocks away from tech and toward more value-conscious sectors could be a warning of trouble ahead.
Our Reading
The numbers tell one story.
Capital Economics sees market internals as a more important signal than immediate political or legal shocks. The firm argues that the combination of elevated headline indices, growing investor attention to valuations, and a leadership shift beneath the surface fits its broader thesis that US equities are in the late stages of a bubble. The emerging pattern is consistent with investors starting to probe more beaten-down corners of the market and hedge against the risk that the mega-cap growth trade unravels.
The rotation began quietly in late 2025 but has gathered momentum through the early weeks of 2026.
Higgins cautions that it’s too early to declare a durable regime change.
One key difference this time is timing within the style spectrum: value stocks are already outpacing growth.
The bursting of the next bubble in the stock market might be followed by periods in which small-cap and value stocks outperformed their peers for a very long time.
