Warren Buffett's Stock-Selling Spree: What $187 Billion Tells Us About Market Risk

Berkshire Hathaway’s recent financial disclosures paint a sobering picture: the investment powerhouse has been a net seller of equities for 13 consecutive quarters, liquidating $187 billion in stock holdings since late 2022. This sustained divestment by Warren Buffett and fellow portfolio manager Ted Weschler sends a powerful message to investors watching the market climb higher. The question is no longer what Buffett is buying—it’s why he’s selling.

The $187 Billion Signal: Why Warren Buffett Stopped Buying

Back in 2018, Warren Buffett declared that it was “hard to think of very many months when we haven’t been a net buyer of stocks.” Fast forward to today, and the script has completely flipped. Over the past 13 quarters, Berkshire Hathaway has consistently divested more shares than it acquired, accumulating $187 billion in net stock sales. While it’s true that the company initiated positions in some notable names like Alphabet, UnitedHealth Group, and The New York Times last year, these purchases were dwarfed by overall selling activity.

The company’s argument for this shift is straightforward: Berkshire’s tangible book value has surpassed $580 billion—more than double what it was in 2018. With such a vast capital base, few investments are large enough to meaningfully impact the portfolio. Yet even with over $300 billion sitting idle in cash and equivalents, Buffett and Weschler continued selling in every single quarter. This sustained divestment despite massive dry powder isn’t a liquidity issue—it’s a valuation concern.

Market Valuations Hit Dangerous Levels: The CAPE Ratio Warning

The culprit becomes clear when you examine the S&P 500’s cyclically adjusted price-to-earnings (CAPE) ratio. In February 2026, this metric reached 39.8—a valuation level that hadn’t been witnessed since the dot-com crash of October 2000. To put this in perspective, the S&P 500 has recorded a CAPE multiple exceeding 39 in only 26 months across its entire 69-year history. That means we’re in extraordinarily rare territory.

Economist Robert Shiller developed the CAPE ratio precisely to identify when stock market indexes become overextended relative to earnings. The metric smooths out earnings over a 10-year period to filter out temporary business cycles, revealing the true underlying valuation. By this standard, today’s market is not just expensive—it’s among the most expensive it has ever been.

What History Says About Today’s Stock Market

The historical data offers a stark warning. Whenever the S&P 500’s monthly CAPE multiple has exceeded 39, the index has followed a predictable pattern of weakness:

• Within 6 months: 0% average return
• Within 1 year: -4% average decline
• Within 2 years: -20% average decline
• Within 3 years: -30% average decline

If current trends align with historical precedent, the S&P 500 could decline by 4% within the next year, 20% by February 2028, and potentially 30% by February 2029. These are significant drawdowns that would test investor discipline.

Of course, historical patterns don’t guarantee future outcomes. One critical variable that wasn’t present during previous CAPE extremes is artificial intelligence. If enterprises rapidly adopt AI technology and earnings accelerate beyond current expectations, the index could continue climbing while the CAPE ratio naturally compressed to more reasonable levels. In that scenario, today’s valuations might prove justified, not reckless.

How Investors Should Respond to Buffett’s Cautious Stance

The takeaway from Warren Buffett’s prolonged selling spree isn’t that the market will inevitably crash—it’s that conditions no longer offer the margin of safety that value investors have historically demanded. This should prompt a fundamental reassessment of investment strategy.

Rather than chasing current market momentum, consider building a portfolio around Buffett’s stated investment criteria: seek equities trading at reasonable valuations where earnings are likely to be meaningfully higher five years from now. Equally important is temperament management. Sell any positions you would feel uncomfortable holding through a significant market correction—typically defined as a 20-30% decline from peak levels.

The broader lesson is that Warren Buffett’s $187 billion in stock sales represents not a market forecast but a values statement. He’s signaling that at today’s prices and valuations, the risk-to-reward tradeoff is unfavorable. Whether the market heeds that warning or ignores it, individual investors should use this moment to honestly appraise their own holdings and ensure they align with fundamentals rather than momentum.
