Analyst: US Stock Market Faces ‘Double Bubble’ Risk, Potential for Crash

The current market environment shows a ‘dual bubble’ — one in profitability and one in price — raising concerns about long-term sustainability.

Key Points

Wall Street analysts warn that both stock prices and earnings expectations are showing signs of a bubble, with the current valuation far exceeding historical norms.
The S&P 500’s expected P/E ratio has dropped from 22.4x one year ago to 20.51x, despite a 20% price increase, indicating that expectations are rising faster than prices.
The Shiller CAPE ratio is currently at 41x, approaching the peak levels seen during the 2000 internet bubble, suggesting a potential ‘price bubble on top of a profit bubble’.
Recent earnings growth has outpaced long-term trends by 1.8 standard deviations, and if normalized, the CAPE ratio would rise to 67.6x — a level higher than any historical peak.
Analysts caution that the current profitability surge may not be sustainable, especially given the shift of large tech firms toward capital-intensive AI infrastructure.
