Warren Buffett does not issue dramatic market warnings often. He is built for patience, not panic. This is exactly why the signal buried inside his best-known valuation yardstick is worth paying close attention to right now.
The number has just hit a level that Buffett himself once described as playing with fire. And it is not even close to the edge anymore. It has blown past it.
What the Buffett Indicator says about the stock market
The Buffett Indicator, which measures the total value of U.S. stocks as a percentage of GDP, according to GuruFocus, now stands at 227%. That is roughly one-sixth higher than the 200% threshold Buffett himself identified as the danger zone.
Buffett first laid out this framework in a 2001 Fortune article he wrote during the dot-com collapse. “If the relationship approaches 200% as it did in 1999 and 2000, you are playing with fire,” he wrote. The Indicator has now climbed well beyond that level, Fortune noted.

The S&P 500 currently sits near an all-time record of 7,165, having rebounded from the selloff triggered by the Iran war earlier this year.
That recovery has pushed valuations to levels that Buffett’s framework says are historically dangerous territory.
Why this S&P 500 reading is unusually alarming
There are two compounding problems at today’s reading, according to Fortune’s analysis of Buffett’s framework.
The first is corporate profit concentration. Profits now represent 12% of GDP, well above the historical average of 7% to 8%, Fortune reported. Bulls argue this justifies the current market level.
But the counter-argument is more persuasive historically: Fat margins attract competitors, which eventually drive down prices and compress the very earnings for which investors are paying a premium.
As the late Nobel-winning economist Milton Friedman said, “Corporate earnings as a share of national income cannot rise beyond their historic share of GDP for long periods,” Fortune noted.
The second problem is valuation. The S&P 500’s price-to-earnings ratio based on forecast Q1 GAAP net earnings now exceeds 28, roughly two-thirds above the 100-year average of approximately 17, according to Fortune.
That means investors are not just paying for higher profits. They are paying significantly more for each dollar of those profits than historical norms would suggest.

What history says about the Buffett Indicator’s 227% level
The last two times the Buffett Indicator reached these heights, the outcomes were painful. Fortune tracked both episodes.
When the Indicator peaked at 200% during the dot-com bubble in March 2000, the S&P 500 eventually fell by roughly half from its high. When it reached just over 200% again in November 2021, it triggered a 19% decline before stabilizing, Fortune reported.
At 227%, the current reading has entered territory the Indicator has never sustained before. That does not guarantee an immediate crash.
Buffett himself has always been clear on this point: his framework predicts that reversion will happen, not when it will happen. Markets can stay expensive for extended periods before reality reasserts itself.
Key valuation figures as of April 2026:
- Buffett Indicator: 227%, roughly one-sixth above the 200% “playing with fire” level, GuruFocus confirmed
- S&P 500 level: Approximately 7,165, near an all-time record, Fortune reported
- S&P 500 forward P/E: Above 28, versus a 100-year average of approximately 17, according to Yahoo Finance
- Corporate profits as share of GDP: 12%, versus a historical average of 7% to 8%, Fortune noted
- Buffett Indicator at dot-com peak (March 2000): 200%, followed by roughly a 50% S&P 500 decline, Fortune confirmed
- Buffett Indicator at November 2021 peak: Just over 200%, followed by a 19% decline, Fortune reported
- Berkshire Hathaway cash position: Near a record high, as Buffett has been selling more stocks than he has bought in recent quarters, Yahoo Finance noted
Berkshire’s cash is itself a signal
Beyond the Indicator, Buffett’s behavior with Berkshire Hathaway’s money sends its own message. The company has been selling more stocks than it buys and has built one of the largest cash positions in its history.
Buffett has always preferred to deploy capital when he sees genuine value. When he holds back, it signals that he does not see enough attractive opportunities at current prices. His cash pile is not just a defensive move. It is a vote of no confidence in the market’s current risk-reward balance.
In that sense, Buffett is saying the same thing through action that the Indicator is saying through math. He is not predicting a crash. He is simply not finding enough to buy at prices that make sense. And when the most patient buyer in the history of markets decides the market is too expensive to buy aggressively, that is worth noticing.
What Buffett’s market warning means for investors
The warning is not a call to liquidate everything. Markets can stay expensive for long stretches, and timing a correction is notoriously difficult even for professionals. Buffett himself has never claimed his framework tells you when to sell, only that extreme readings carry extreme risk.
But the combination of a 227% Indicator reading, a P/E ratio two-thirds above its century-long average, and a Berkshire cash pile near record levels does add up to something. It suggests the return outlook from current prices is considerably weaker than the recent rally might imply.
Buffett’s core philosophy applies here as it always has. Understand what you own. Buy it at a sensible price. And do not mistake a rising market for a cheap one.
At 227%, the math says the market is neither sensibly priced nor cheap. That is the message investors need to sit with before chasing the next rally.
