The Common Belief: Buffett Is Sitting on Cash Because He Knows Something
Over $300 billion. That is the size of the cash and cash-equivalent pile Berkshire Hathaway has carried in recent years, and it has become the single most-cited exhibit in every crash-is-coming argument on the internet. As of September 26, 2026, that figure — reported by CNBC in its ongoing coverage of Berkshire's balance sheet — is routinely presented as a coded warning from the world's most famous investor. Our read: the cash pile is real, the warning is largely invented by the people quoting it.
According to Google News, The Motley Fool published a piece arguing that a stock market crash is on the way and that investors should respond using Warren Buffett's long-standing playbook. The factual spine of that argument is solid. The inference most readers draw from it is not.
Here is the part the surface reporting skips. Market analysts have flagged Berkshire's large cash position as a signal of caution, and that is fair. But Buffett has also, for six decades, told anyone who would listen that he does not attempt to forecast crashes. Those two facts are frequently stacked into a conclusion neither one supports: that Buffett has a date circled on a calendar.
Where It Breaks Down: Run the Percentage, Not the Headline Number
A raw dollar figure is the most misleading number in finance, because it scales with the size of the company holding it. Buffett keeps roughly 20% to 30% of Berkshire's portfolio in cash equivalents during periods he considers overvalued. That is the number that actually matters — and it reframes everything.
In plain terms: a 20–30% cash allocation is not a bunker. It is a conservative-but-ordinary defensive posture, the same one a cautious retiree might run. If a reader with a $50,000 investment portfolio applied Buffett's own upper-bound ratio, the math works out to $15,000 in cash and $35,000 still invested. That is a portfolio that is 70% exposed to stocks. Nobody describes a 70%-invested portfolio as a crash bet.
Now put that against his other headline number. Berkshire has delivered approximately 20% annual returns over roughly six decades, versus about 10% average annual returns for the S&P 500 over the long term. That gap — 20% against 10% — is the actual story, and it is a compounding story, not a timing story.

Compare the two ways a reader could act on this news, because they lead to opposite places. Path A treats the cash pile as a sell signal and goes to cash entirely. Path B treats it as a reminder to hold a cash buffer while staying invested. Under a crash that arrives next month, Path A wins on paper. Under a crash that arrives in four years — or never arrives in a recognizable form — Path A has forfeited years of compounding at roughly 10% a year while earning a money-market yield, and Path B has captured most of the upside with a cushion intact. Buffett's own allocation is Path B. He has never been on Path A.
The Skeptic's Pushback
A fair objection: if valuations really are stretched, isn't refusing to reduce exposure just stubbornness dressed up as discipline? There is weight to that. Buffett's line — "Only when the tide goes out do you discover who's been swimming naked" — is explicitly a warning about weak fundamentals getting exposed, and he did not say it as a compliment to buy-and-hold-anything investors.
But note what the quote targets. It targets which companies you own, not whether you own companies. The defensible version of caution is upgrading quality inside a portfolio. The indefensible version is exiting the market and hoping to guess the re-entry point. During downturns, his documented behavior is buying quality businesses at marked-down prices, not liquidating.
The second-order point that almost nobody makes: Berkshire's cash is not a market forecast, it is a liquidity weapon. A firm holding hundreds of billions in cash equivalents can act as the buyer of last resort when everyone else is forced to sell — which is exactly how Berkshire has historically profited from panics. Retail investors copying the cash percentage without the intention to deploy it are copying the posture and skipping the purpose.

What the Sources Actually Give You — and What They Don't
Worth naming the divergence. The Motley Fool's framing leads with a crash prediction and offers Buffett as the remedy. CNBC's Berkshire coverage tends to report the cash position as a data point about one company's capital allocation, without the crash overlay. Berkshire's own shareholder letters — the primary source, at berkshirehathaway.com — are where the philosophy is stated in Buffett's words rather than summarized. (Notably, that site was not directly reachable during research compilation on September 26, 2026, which is a good reminder that secondhand summaries of Buffett are far more abundant online than the letters themselves.)
The full picture across those three sources reveals something no single one states: the crash-prediction framing is an editorial layer added on top of a balance-sheet fact. Strip the layer, and what remains is a company holding a conservative cash ratio and a founder who has said, repeatedly, that timing is not the game. Market crash predictions cluster during extended bull markets and elevated valuations — which means their frequency tells you about sentiment, not about timing.
Three Moves for This Week
Add up your investable assets, then divide your cash and money-market balances by that total. If you are at 5%, Buffett's 20–30% range suggests room to build a buffer. If you are already at 40%, the honest read is that you are more defensive than Berkshire, not less. This takes ten minutes and replaces a vague feeling with a number — the same discipline behind Smart Investor AI's comparison of dividend stocks against money market yields.
Buffett's standard: "If you aren't willing to own a stock for ten years, don't even think about owning it for ten minutes." Go position by position and answer it honestly. Anything that fails is a candidate to trim now, on a calm day, rather than in a panic. This is quality upgrading, not market timing — and it is the part of the advice that survives whether or not a crash arrives.
For most investors, Buffett's actual recommendation is not a cash pile at all — it is low-cost S&P 500 index funds bought consistently. The S&P 500 has historically recovered from every major crash, averaging about 10% annually over the long term. A fixed monthly contribution converts volatility from a threat into a discount, without requiring any prediction. Set the transfer, then stop checking the stock market today every morning. Modern AI investing tools and robo-advisors can handle the rebalancing, but the automation matters more than the algorithm — and no AI investing tools available today can reliably call a crash date either. Good financial planning is mostly the removal of decisions.
Bottom Line
On balance, our analysis is that Berkshire's cash position is being read backwards. A 20–30% cash allocation held by a firm whose founder publicly rejects market timing is evidence of a patient buyer waiting for better prices — not a sell signal for a household portfolio. The more likely outcome for an investor who exits stocks on a crash prediction is not a well-timed escape but several years of missed compounding and an expensive re-entry. "Be fearful when others are greedy, and greedy when others are fearful" is a rule about your own emotional state, not a forecasting tool. The greed to be wary of, right now, includes the appetite for confident predictions.
Frequently Asked Questions
Should I sell my stocks if a market crash is coming in 2026?
Buffett's documented approach argues against it. He advocates long-term value investing over attempting to time crashes, and during downturns his behavior has been to buy quality companies at discounted prices rather than sell. Selling requires two correct guesses — when to exit and when to return — and the S&P 500's roughly 10% long-term average annual return has historically been earned by staying invested through recoveries. This is not advice for your situation; it is a description of his stated philosophy.
Is it better to hold cash during a stock market crash?
Some cash, yes — as a buffer and as ammunition. Buffett holds 20% to 30% of Berkshire's portfolio in cash equivalents when he views the market as overvalued, which leaves 70% to 80% still invested. The purpose of that cash is to deploy it into falling prices, not to sit in it indefinitely. Cash held with no plan to buy is just a slow loss to inflation.
What stocks does Warren Buffett buy during market crashes?
His stated criterion is quality businesses at discounted prices — companies with strong fundamentals that survive when, as he put it, "the tide goes out." For most individual investors, his actual public recommendation has been different and simpler: low-cost S&P 500 index funds, which spread the bet across hundreds of companies rather than requiring you to identify the survivors.
Why does Berkshire Hathaway hold over $300 billion in cash?
Berkshire has historically built large cash reserves during periods it considers overvalued, and the position has exceeded $300 billion in recent years. Market analysts read this as a signal of caution, which is reasonable. But as a percentage of the portfolio it stays within the same 20–30% band Buffett has used before, and the cash functions as buying power for opportunities rather than as a dated crash forecast.
