Market analysts and indicators suggest growing risks of a significant stock market correction due to high valuations. Early warnings highlighted concerns regarding overvaluation driven by artificial intelligence hype, private credit growth, and speculative factors, with some investors comparing the potential for a sharp decline to the 1987 crash.

Investor Michael Berry has reinforced these concerns, suggesting U.S. equities are near a major peak. He warns that overvaluation is being fueled by AI-related hype and private-credit growth, noting that upcoming events like the Jackson Hole symposium and central bank meetings could influence market direction. Berry has maintained short positions in several overvalued stocks and ETFs, including Nvidia, Tesla, and the iShares Semiconductor ETF.

Adding to the institutional concern, the European Central Bank (ECB) issued a warning regarding a potential correction in U.S. technology stocks. The ECB noted that valuations for the ‘Magnificent Seven’—including Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla—are reaching levels reminiscent of historical technological bubbles. The bank cautioned that if profit growth fails to meet highly optimistic investor expectations, a sharp price correction could follow.

This volatility poses a risk to European financial stability, as European households, pension funds, and insurance companies have an estimated €440 billion exposure to these U.S. tech giants. The ECB further noted that current economic conditions may leave policymakers with less room to use interest rate cuts or fiscal policy to cushion a major downturn compared to the dot-com era.
