In a recent Substack post, Michael Burry, known for his pivotal role in “The Big Short” narrative, asserted that the stock market has “jumped the shark,” predicting an imminent “complete reversal” of the tech-heavy NASDAQ 100. He highlighted striking similarities between current market conditions and the final throes of the dot-com bubble, characterizing the environment as reminiscent of the late 1990s.
Burry’s concerns were echoed by renowned investor Paul Tudor Jones during a CNBC interview on May 8. Jones articulated that the circumstances today mirror those of 1999, warning that if the current upward momentum continues, it could lead to “breathtaking kinds of corrections.”
Despite these warnings, Wall Street analysts grapple with the disconnect between the soaring stock prices of major U.S. companies and lackluster economic fundamentals. Current indicators reveal persistent inflation, recently reflected by the April Consumer Price Index report, which noted a 12-month rise of 3.7% in consumer prices. Additionally, GDP growth remains relatively stagnant, the 10-year Treasury yield hovers in the mid-4% range, and high energy costs are straining household budgets, exacerbated by ongoing geopolitical conflicts. Many are also losing faith in potential significant interest rate cuts from the Federal Reserve.
Bulls on Wall Street attribute the robust stock performance to a surge in corporate earnings, which they argue is primarily driven by advancements in artificial intelligence (AI). Burry expressed skepticism, observing the media’s relentless focus on AI as a panacea for the looming economic challenges. He cautioned that while earnings per share (EPS) may be soaring, such figures are often inflated and unsustainable. Remarkably high EPS can create an artificially low price-to-earnings (P/E) ratio, misleading investors about stock valuation. Should EPS decline, the P/E ratios would spike, positioning stocks as overly expensive.
Presently, corporate profits are at historic highs in relation to national income, signaling a potential reversion to the mean, where profits may decrease toward long-term averages. This phenomenon has historically accompanied periods of inflated EPS, indicating that today’s earnings mask the true valuation of stocks.
For a more accurate assessment of stock prices, one must consider the cyclically-adjusted price earnings ratio (CAPE) developed by Nobel laureate Robert Shiller. The CAPE employs a 10-year average of inflation-adjusted earnings, providing a steadier assessment of valuation compared to standard P/E ratios. As of May 11, the CAPE reached 40.3, marking a perilous threshold. The index has only surpassed 40 during 21 instances throughout its 145-year history, all concentrated in the period from January 1999 to September 2000—the height of the dot-com bubble. Even during the build-up to the Great Depression, the CAPE barely exceeded 30.
The question for investors now is what returns they might expect from U.S. large-cap stocks moving forward. Historical data suggests that following instances of CAPE exceeding 40, it took over 12 years for the S&P 500 to recover to its previous highs. Although investors did receive dividends during this time, capital gains were essentially non-existent, and returns lagged behind inflation—highlighting the perilous nature of buying into high-valuation environments.
Ultimately, this current market surge exemplifies the unpredictable nature of financial markets. While some may cling to optimism, the cautious warnings from seasoned investors like Burry and Jones emphasize the potential for significant risks ahead, serving as a stark reminder that market euphoria may often precede prolonged downturns.
