Michael Burry, Paul Tudor Jones, and a Nobel laureate all anticipate a stock market correction

(SeaPRwire) –   In a recent Substack post, Michael Burry, known as the hero of The Big Short book and film, declared that the stock market has “jumped the shark” and warned that a complete reversal is imminent for the tech-heavy NASDAQ 100. Burry drew parallels between current market movements and the final months of the dot-com boom, suggesting the situation resembles the bubble period of 1999–2000.

Renowned trader Paul Tudor Jones echoed Burry’s concerns in a May 8 interview with CNBC. He noted that today’s market dynamics remind him of 1999—the beginning of the infamous tech bubble—and cautioned that if the current trend continues, investors could face “breathtaking corrections.”

Despite Wall Street analysts struggling to explain why major U.S. stocks keep hitting new all-time highs, economic fundamentals appear weak at best. Inflation remains stubbornly high, as shown by the April CPI report released on May 12, which indicated consumer prices rose 3.7% over the past year. GDP growth is sluggish, the 10-year Treasury yield hovers near 4%, energy costs remain elevated due to ongoing geopolitical tensions, and expectations for aggressive Federal Reserve rate cuts have faded.

Proponents of the bullish stance frequently cite surging corporate earnings driven by artificial intelligence (AI) as justification for continued optimism. “Absolutely non-stop AI,” Burry remarked after hearing media commentators repeatedly claim it will solve all economic challenges. “No one is talking about anything else all day.”

However, investors should be cautious: these exceptionally strong earnings per share (EPS) figures are not sustainable. Earnings naturally fluctuate, and when they spike unrealistically high, they distort price-to-earnings (P/E) ratios, making stocks appear cheap when they are actually expensive. Conversely, when EPS drops sharply, P/E ratios can become artificially inflated, misleading investors about valuation levels. Corporate profits currently represent historic highs relative to national income, signaling that they are likely to decline toward their long-term average—a pattern that has repeated whenever earnings exceeded normal bounds in the past. By inflating the earnings denominator, today’s exaggerated EPS numbers mask how overvalued stocks truly are.

A more reliable metric eliminates this distortion by smoothing out short-term earnings volatility to provide a clearer picture of true stock valuation. This approach offers a consistent measure of whether stocks are fairly priced or overextended.

This preferred indicator is the widely respected cyclically-adjusted price-earnings ratio, commonly known as the CAPE ratio, developed by Nobel Prize-winning economist Robert Shiller, professor emeritus at Yale. The CAPE ratio is recognized as one of the most accurate predictors of future investment returns. When it significantly exceeds historical averages, future returns over the next five to ten years tend to be weak; when it falls well below average, long-term gains are more likely.

Specifically, the CAPE ratio calculates a 10-year average of inflation-adjusted earnings, removing the erratic swings and delivering a much more accurate assessment of valuation.

As of May 11, the CAPE ratio had surpassed a critical threshold, reaching 40.3. Throughout its 145-year history, the CAPE has only exceeded 40 on 21 occasions—all occurring within a single continuous span from January 1999 to September 2000, coinciding with the peak of the Dot-Com mania. Even during the lead-up to the Great Depression, the CAPE barely reached 30.

Given this context, what kind of returns can investors expect from the S&P 500 or a diversified portfolio of large-cap U.S. stocks going forward? Historical data provides insight: it took twelve years and five months—until February 2013—for the S&P 500 to recoup the levels seen in September 2000.

During that extended downturn, investors received dividends but saw no capital gains. Overall, returns failed to keep pace with inflation, underperforming even risk-free Treasury securities.

The extraordinary rally we’re witnessing today may simply reflect irrational exuberance. While this view may be incorrect, it is just as plausible as the prevailing Wall Street narrative that portrays a challenging environment as one of unrelenting opportunity.
