Tom Essaye warns the AI-stock index is flashing bubble risk
The AI trade could be inflating a late-cycle stock market bubble, warns Tom Essaye, founder of Sevens Report Research.
‘This bull market in equities has a serious problem’: Strategist warns a crucial AI-stock index is sending a potential bubble signal
In an August 1 client note, Essaye wrote that “every bubble in modern market history has been based on a narrative”—and today, that narrative is AI. But to measure the health of the AI trade, he points to the PHLX Semiconductor Index (SOX), not just Nvidia.
Semiconductors are the “lifeblood” of AI, yet SOX remains below its July 2024 highs while the S&P 500 has climbed nearly 14% in the same period. That lagging performance, Essaye says, is a meaningful divergence:
“If AI remains the primary source of bullish optimism… this market is in trouble and at risk of rolling over sooner than later.”
He cautions that if SOX begins a material selloff, the S&P 500 likely won’t be far behind.
Adding to the risk: weaker recent payrolls, rising continuing jobless claims, and stretched valuations after an ~85% rally from the October 2022 lows.
“It is critical to keep close tabs on economic data right now,” Essaye stressed in an August 8 note, warning the broader market remains vulnerable to considerable downside if economic resilience falters.
