Berkshire Hathaway (NYSE:BRK.B) has amassed a staggering $373.5 billion in net cash and U.S. Treasury bills as of March 31, underscoring Warren Buffett's cautious outlook on current market conditions. This cash position is 1.22 times the book value of its equity and fixed-maturity securities, signaling a defensive posture that has drawn attention from investors and analysts alike.
Massive Equity Unloading in Q1
In the first quarter, Berkshire unloaded approximately $24.1 billion in equities, more than five times the $4.7 billion sold during the same period last year. This aggressive selling, combined with a reduction in its top-five stock holdings from 65% to 61% of the equity book, reflects a strategic shift away from overvalued markets. The top holdings include American Express (NYSE:AXP), Apple (NASDAQ:AAPL), Bank of America (NYSE:BAC), Coca-Cola (NYSE:KO), and Chevron (NYSE:CVX).
Buffett's Warning on Market Sentiment
At Berkshire's annual meeting on May 2, Buffett remarked, "We've never had more people in a gambling mood than now," adding that "prices for an awful lot of things will look awfully silly." This warning comes as the Shiller P/E ratio hovers near 41.6, just below the dot-com peak of 44.19, and U.S. ETF assets have surged to $15.7 trillion, up 17% since the end of 2025. The proliferation of leveraged and inverse ETFs—nearly 200 of the roughly 700 funds launched in 2026—has amplified concerns about market speculation.
Market Signals and ETF Growth
Morningstar analyst Dan Sotiroff noted that the line between investment products and casino-like instruments is blurring. The Buffett indicator, which compares total market value to GDP, now exceeds 233%, further highlighting potential overvaluation. Despite these signals, Goldman Sachs (NYSE:GS) strategist Ben Snider argues that valuations may not revert to historical averages, projecting 7% annualized S&P 500 returns over the next decade, above Goldman's prior 3% estimate but still below the long-term trend.
Berkshire's Strategic Moves Under Greg Abel
Under incoming leader Greg Abel, Berkshire has begun deploying some capital. On June 1, the company invested $16.8 billion over two days, including $10 billion in Alphabet (NASDAQ:GOOGL) shares and $6.8 billion in Taylor Morrison Home (NYSE:TMHC). "Everyone has been waiting for Greg to do his thing," said Steven Check, president of Check Capital Management. However, the overall cash pile remains substantial, with $380.2 billion at the end of March and operating profit up 18% to $11.35 billion in Q1. Stock buybacks were minimal at $234 million, reflecting a cautious approach.
Implications for Investors
Berkshire's larger Treasury-bill holdings boosted after-tax corporate investment income by $98 million in Q1, though this could decline if short-term rates fall. Conversely, a market downturn could provide opportunities to deploy cash. With the S&P 500 trading at elevated multiples and ETF complexity rising, Buffett's historical caution may once again prove prescient. As Abel noted, "It doesn't mean you need to deploy all your capital and spend all your money," while vice chair Ajit Jain admitted, "It is very difficult to sit there and do nothing."
