Warren Buffett's 1987 Shareholder Letter: Investment Logic of Business Value and Operational Stability

In his 1987 letter to shareholders, Warren Buffett delves into the distinction between book value and business value, articulating Berkshire Hathaway's core investment philosophy. First, he explicitly states: "What counts, of course, is the rate of gain in per-share business value, not book value." To illustrate this point, he cites examples such as LTV and Baldwin-United, which displayed high book values prior to their bankruptcies, and Belridge Oil, which was sold to Shell at a price far exceeding its book value. This serves as a reminder to investors that accounting figures often fail to reflect a company's true economic condition; real value lies in the enterprise's ability to generate cash and its competitive moat.

Second, Buffett emphasizes the value of operational stability, opposing the blind pursuit of so-called "high-growth stories." He writes: "Experience, however, indicates that the best business returns are usually achieved by companies that are doing something quite similar today to what they were doing five or ten years ago." He argues that while frequent major changes may sound appealing, they also create opportunities for significant errors and make it difficult to establish durable business franchises. Citing research from Fortune magazine, he notes that only a few companies maintain extremely high return on equity over a decade, and most of these operate in seemingly mundane businesses—products or services that are not glamorous but are executed exceptionally well.

Finally, the letter showcases Berkshire's unique decentralized management system. Buffett mentions: "With managers like ours, my partner, Charlie Munger, and I have little to do with operations. In fact, it is probably fair to say that if we did more, less would be accomplished." This trust stems from identifying excellent managers, such as those leading subsidiaries like Buffalo News and See's Candies. They not only generated astonishing capital returns but also allowed headquarters to focus on capital allocation rather than micromanagement. For today's readers, this provides a clear framework: when evaluating a company, one should focus on the durability of its business model and the autonomy of its management, rather than short-term financial embellishments or aggressive strategic pivots. If you are analyzing a traditional consumer goods company whose product lines and profit models have remained stable over the past decade, and whose management enjoys high autonomy, it may possess greater long-term investment value than a tech company constantly launching new concepts but lacking a track record of execution.
