Could the Stock Market Crash? A Signal Seen Six Times in 155 Years
Bharatmorningnews.com – Could the stock market crash within the next twelve months? That question has moved from academic curiosity to front-page anxiety as the cyclically adjusted price-to-earnings ratio — the CAPE, or Shiller PE — has climbed to 41.1. Since continuous tracking began in 1871, a reading at or above that threshold has materialized only six times across roughly 155 years of market history. The long-run average of the indicator sits near 17.8, meaning today’s figure is more than double what investors have experienced over the long haul. When the ratio holds above 30 for several consecutive months, analysts classify the episode as one of those six historic stretches, and the present market qualifies as the sixth.
How the CAPE Ratio Works and Why It Matters
Unlike a trailing twelve-month P/E, which can swing wildly with a single quarter’s earnings surprise, the CAPE divides the current price level by the inflation-adjusted mean earnings of the prior ten years. That decade-long smoothing strips out cyclical noise and exposes whether equities are priced against what the economy can sustainably produce over a multi-year horizon. A sustained spike therefore points to a structural disconnect between price and fundamental earning power, not a temporary dip in reported profits.
The ratio does not carry a built-in countdown clock. It tells you the environment is statistically rare; it does not tell you the date of correction.
What Happened After the Five Previous Episodes
The first episode peaked in 1929. After a decade of speculative froth, the October crash launched a bear market that dragged prices lower well into the early 1930s, compounding the damage of the Great Depression. The second unfolded from 1997 through 2001, when the CAPE touched roughly 44 on the back of technology-stock exuberance. The dot-com bubble ultimately deflated, and the Nasdaq Composite shed approximately 77 percent from peak to trough, wiping out trillions in market capitalization. The key lesson: an overvalued market can keep extending its excess before the correction arrives.
Episodes three and four bracketed the pandemic shock. Global lockdowns in early 2020 compressed a bear market into weeks rather than months, producing one of the fastest equity drawdowns on record. The fifth episode ran from 2020 through 2022: central banks flooded the system with liquidity at near-zero rates, inflation surged to roughly nine percent, and the Federal Reserve hiked aggressively. The S&P 500 slid into a bear market in 2022 as investors repriced the present value of distant future cash flows, with high-growth technology names bearing the brunt of the selling.
The sixth episode — the one unfolding now — is distinguished by a variable absent from every prior instance: the sheer scale of artificial-intelligence capital expenditure. Corporations are committing hundreds of billions of dollars to data centers, graphics processing units, high-speed networking gear, advanced memory, and power-generation capacity. That spending underpins a large share of the current rally’s momentum, and if borrowing costs rise — a scenario some participants link to the prospect of a new Federal Reserve chair in Kevin Warsh pushing rates higher — the financing cost of that buildout increases. A deceleration in AI-related capex could remove a principal pillar propping up today’s equity valuations, triggering a rapid downward repricing as buyers withdraw willingness to pay current multiples for uncertain future earnings.
Frequently Asked Questions
Does a high CAPE ratio mean the market will crash next month? No. The ratio flags statistically rare valuation territory but does not encode a timing mechanism. The 1997–2001 episode showed that excess valuations can persist — and even widen — for years before a correction materializes.
How many times has the CAPE exceeded 30 for multiple consecutive months? Six times since tracking began in 1871. The current episode is the sixth. Prior episodes culminated in the 1929 crash, the dot-com deflation, the early-2020 pandemic drawdown, and the 2022 rate-hike bear market.
What makes the current episode different from earlier ones? The dominant driver of valuation support is AI infrastructure spending at a scale never previously seen in equity markets. If that capital cycle slows — whether from higher financing costs or from revenue shortfalls — the repricing risk is concentrated in growth and technology names.
Is the CAPE ratio the only indicator to watch? It is one of several long-horizon gauges. Investors typically pair it with credit-spread behavior, earnings-revision momentum, and liquidity conditions before drawing conclusions about near-term direction.
