Munger Misses Out on $200 Million by Refusing to Buy Belridge Oil
In 1977, Charlie Munger declined to purchase an additional 1,500 shares of Belridge Oil due to temporary cash flow issues. This transaction, which could have been easily completed, skyrocketed in value two years later after Shell Oil's acquisition, becoming one of Munger's "most foolish decisions" he frequently mentioned in his later years.
Initially, a broker offered Munger 300 shares of Belridge Oil at $115 per share, totaling about $34,500. Munger quickly bought this batch of shares, believing the company's liquidation value could reach about three times the market price, indicating it was an undervalued asset.
Not long after, the same broker contacted Munger again, stating there were still 1,500 shares available at the same price of $115 per share, totaling about $172,500. Munger had thoroughly researched the company's fundamentals and later described the opportunity as "one that even a fool could see was almost guaranteed to make money, with a high probability of significant gains."
The issue was cash: Munger's available cash at the time was insufficient to cover the additional investment of over $170,000. To buy the shares, he would have to sell other holdings or borrow money. After about 10 minutes of consideration, he ultimately decided against the 1,500 shares, finding the hassle of selling something too troublesome.
In 1979, Shell Oil acquired Belridge Oil for about $3.6 billion, with a per-share price of $3,665, approximately 32 times Munger's purchase price; the company owned over 20,000 acres of land with proven reserves exceeding 376 million barrels of crude oil. The initial 300 shares Munger bought also surged in value to about $1.1 million.
The real winners were companies like Shell, willing to pay a premium for scarce quality assets and capable of long-term extraction. The acquisition price was about 82 times Belridge's earnings at the time, and Shell later extracted oil worth over $60 billion from this oil field. Munger, who missed out on the 1,500 shares, estimated in his later years that had he purchased them and reinvested like the 300 shares, the principal could have grown to nearly $10 billion, missing out on compounding due to a "small cash flow issue."
Munger mentioned this incident multiple times at Daily Journal shareholder meetings, stating, "This mistake cost me $200 million, simply because I found it troublesome to sell something," lamenting, "There are not many great opportunities in life, and when the opportunity finally came, I messed it up."

This is not the only instance where Munger faced "certainty opportunities" with extreme behavior; this time, however, it serves as a negative example. In 1972, Munger advocated for Buffett to acquire See's Candies at nearly three times its book value—at the time, almost all Berkshire's old shareholders thought it was "too expensive," but this transaction is now recognized as a turning point for Berkshire from "cigar butt investing" to "long-term holding of quality companies"; around 2008, Munger again led the purchase of BYD shares through Daily Journal, holding them for over ten years without wavering. Belridge is precisely the counterexample to this principle of "thorough research and bold investment": certainty was well-researched, yet he hesitated due to a minor cash flow issue.
From a funding perspective, the 1,500 shares of Belridge were not public market orders but rather off-market agreements initiated by the broker—these types of transactions have asymmetric information and poor liquidity, making it difficult for ordinary investors to enter, representing scarce chips only available to "insiders." Munger used available cash to purchase the initial 300 shares, while the additional 1,500 shares would require selling holdings or borrowing to leverage, and he chose "not to fuss." Two years later, Shell, as an industrial capital entity, fully acquired Belridge, with a pricing logic not based on short-term stock price speculation but rather on the clear proven reserves and long-term extraction rights of Belridge—this was a typical path of "industrial capital acquiring undervalued assets," rather than short-term arbitrage by financial capital.
Similar "certainty premium" logic has run through Munger and Buffett's entire investment careers, from See's Candies to Coca-Cola, fundamentally paying for scarce certainty rather than chasing low prices. In the industry context, the late 1970s marked a wave of mergers and consolidations in the U.S. oil industry, with multinational giants like Shell and Exxon aggressively acquiring independent oil field operators to secure proven reserves, and Belridge was a typical target in this wave of resource consolidation.
Structural judgment: The core of this event is capital concentration—the extreme mismatch between Belridge's stock price and its liquidation value and reserve value means that the excess returns brought by this mismatch can only be realized through concentrated heavy investment; any dispersion or hesitation will dilute the compounding effect of returns. Munger's lesson precisely proves this mechanism in reverse: excess returns from value investing are never earned through diversified holdings but through bold concentration on a very few high-certainty opportunities; giving up on increasing positions due to cash flow issues essentially means actively forfeiting the window for compounding concentration to be realized.

The cost of hesitation is always more expensive than imagined.
When certainty is scarce, hassle should not be a reason for refusal.
Compounding favors those who dare to concentrate, punishing those who love to be comprehensive.
