Semiconductor stocks are overvalued relative to the S&P 500 compared to pre-ChatGPT levels, creating downside risk
Too little corroboration in the last 3 days to call a trend (1 article). Watching for it to gain traction.
Semiconductor valuations relative to the S&P 500 have expanded significantly beyond pre-ChatGPT levels, creating a gap that would require substantial index declines to normalize, according to technical valuation analysis.
Relative valuation extremes create structural pressure for mean reversion; when a sector trades at multiples unseen in prior cycles, the mathematical requirement for normalization becomes a persistent headwind regardless of earnings growth. This dynamic typically constrains upside and increases downside risk until the gap closes.
"A decline of that size would extend two months of declines and bring the index back to a valuation relative to the S & P 500 unseen since the launch of the ChatGPT chatbot back in 2022. As the AI boom caught fire over the past four years, that discount turned into a 15% premium over the S & P."
