At 237.4% of GDP, the U.S. stock market is valued at about 2.37 times the economy beneath it. The Buffett Indicator puts that valuation into perspective.

The Simple Equation
The ratio asks a straightforward question: how much are investors paying for the publicly traded claims on the economic activity beneath them?
Buffett’s Single Best Measure
In his December 2001 Fortune essay, Warren Buffett described stock-market value relative to GNP as “probably the best single measure of where valuations stand at any given moment.”
Buffett described 70–80% as a favorable buying range and warned about readings approaching 200%. Those were observations about his historical series, not permanent buy-and-sell rules.
Modern versions often use GDP instead of GNP. Market coverage, overseas earnings, interest rates, and the chosen historical baseline affect interpretation. No single threshold tells us when prices will turn.
A growing economy does not automatically make every market price attractive. The starting valuation still matters.

Buffett’s original discussion used GNP. The modern GDP series shown here is related, but the figures should not be treated as directly interchangeable.
METHODOLOGY MATTERS
The Reading and the Model
A valuation reading describes today’s price. A return model asks what could happen under a particular set of assumptions. Neither is a timetable for a market decline.
GuruFocus snapshot: September 4, 2026. The estimate includes dividends and assumes valuation moves toward its recent 20-year average over eight years. It is a model output, not a realized return or a guarantee.
The planning question: would your retirement strategy still hold up through a prolonged period of weak returns? Test a range of outcomes alongside inflation, withdrawals, and your ability to adjust spending.

This is not a prediction that the market crashes tomorrow.
Expensive markets can remain expensive for years. Selling everything because one indicator is high would misuse the evidence. The lesson is about expected return, downside exposure, and preparation.
What This Actually Means
When you are adding money, lower prices can let new contributions buy more shares. Recovery still takes time and is never assured.
When you are taking money out, a decline can force you to sell more shares to fund the same spending. The order of returns matters as well as their average.
Still Accumulating
Lower prices can become an opportunity.
Regular contributions may help you buy through a downturn. Your time horizon, job stability, and cash needs still matter.
Living From the Portfolio
Withdrawals can make a decline harder to recover from.
Withdrawals may force shares to be sold during the decline, removing capital that can no longer participate in the recovery.
