As equity markets continue to set new records, conventional wisdom would suggest a more aggressive approach from leading investors.
Warren Buffett did the opposite, and the sheer scale of his three-year equity retreat is becoming impossible for investors to ignore.
Before stepping down as Berkshire Hathaway’s chief executive at the end of 2025, Buffett was a net seller of equities for 13 consecutive quarters.
The gap between what Berkshire sold and what it purchased across that stretch reached approximately $187 billion, according to Berkshire Hathaway’s quarterly SEC filings.
Buffett’s preferred gauge of stock market value hit its highest reading on record, surpassing the threshold he once described as dangerous.
Berkshire’s cash pile nearly quadrupled as Buffett stepped away from stocks
Berkshire Hathaway’s cash and Treasury bill holdings surged from roughly $100 billion when the current bull market began in late 2022 to a record $397.4 billion.
That figure, confirmed in the company’s first quarter 2026 filing with the Securities and Exchange Commission, represents more than a third of the conglomerate’s total market value.
During the first quarter of 2026, Berkshire continued the pattern by selling roughly $8 billion more in equities than it purchased, according to the filing.
Uninvested proceeds generally flow into short-term Treasury bills, where they earn annualized interest income of about $12 billion at yields of about 3.7%, according to Berkshire’s quarterly report.
“We’ve never had people in a more gambling mood than now,” Buffett said in a CNBC interview at the sidelines of Berkshire’s May 2, 2026 annual meeting, pointing to heavy speculation through one-day options.
The Buffett Indicator just crossed into record territory
The ratio of total United States market capitalization to gross domestic product, widely known as the Buffett Indicator, is the valuation tool at the center of this story.
Buffett called the ratio ‘probably the best single measure of where valuations stand at any given moment’ in a 2001 Fortune magazine article.
Since 1970, the indicator has averaged about 88%, meaning the collective value of U.S. equities has typically been below total national economic output, according to a Motley Fool analysis of the historical data.
On June 1, the ratio reached a record closing high of 238.5%, roughly 171% above that average, according to The Motley Fool’s analysis.

The indicator remained above 235% as of early July, well beyond the 200% level that Buffett warned about in the same 2001 Fortune article.
The current reading exceeds the threshold he described as dangerous by more than 35 points, remaining near record highs into July.

A second valuation gauge confirms the signal from Berkshire
The S&P 500 Shiller price-to-earnings ratio smooths reported earnings across a full decade to eliminate distortions from short-term business cycles.
That ratio stood at approximately 41.6 as of early July, making this the second-most expensive stock market on record, dating back to January 1871, according to data from Robert Shiller’s dataset, as tracked by GuruFocus’s Shiller PE.
Over 155 years of data, the Shiller ratio has averaged approximately 17.4, and every prior reading above 30 has been followed by a significant market decline.
Each of those corrections brought losses of 20% or more in at least one major U.S. stock index, according to The Motley Fool’s analysis of Shiller’s historical CAPE dataset.
Martin Romo, chair and chief investment officer at Capital Group, argued in the firm’s 2026 stock market outlook that the current environment demands a more selective approach.
“I believe the importance of active stock selection, supported by deep research, has never been clearer,” Romo stated in the report.
What Berkshire’s new leadership is doing with the cash
Greg Abel, chief executive officer of Berkshire Hathaway, told shareholders at the company’s annual meeting on May 2, 2026, that the conglomerate’s massive cash reserve serves a deliberate strategic purpose and that Berkshire will not compromise its financial independence to chase deals in an overpriced market.
We do not intend to be beholden to anyone. We start with that position
Abel has made selective moves with the cash, including Berkshire’s agreement to acquire homebuilder Taylor Morrison for about $8.5 billion and a $10 billion commitment to Alphabet, according to the companies’ joint press release.
He also restarted Berkshire’s share repurchase program in March for the first time since May 2024, spending roughly $234 million on buybacks in the quarter.
Each transaction represents a small fraction of the total cash reserve, which suggests that Berkshire still finds limited value at current market prices.
The record valuations may not signal an immediate downturn
The convergence of record cash reserves and extreme valuation readings does not automatically translate into near-term losses.
Both the Shiller ratio and the Buffett Indicator forecast returns over decade-long windows, according to Current Market Valuation’s methodology notes.
Romo noted in Capital Group’s 2026 outlook that markets are moving beyond a handful of dominant technology stocks.
Investors now have more opportunities, making careful research important for finding strong investment prospects.
Buffett’s career illustrates the logic behind his approach: his record of buying during genuine distress only works because he held enormous cash reserves when others were fully invested.
