In his 1987 letter to shareholders, Warren Buffett details the exceptional performance of Berkshire Hathaway, emphasizing that the company's business value consistently outpaces its book value. He attributes this success to a decentralized management style and a collection of "Sainted Seven" non-financial businesses, such as See’s Candies and the Buffalo News, which achieve high returns with minimal debt. Buffett explains his investment philosophy through the allegory of "Mr. Market," advising investors to ignore short-term volatility and focus on the long-term intrinsic value of excellent enterprises. The report also highlights the challenges of the insurance industry, noting that Berkshire’s vast financial strength and "float" provide a distinct competitive advantage during market cycles. Throughout the text, he maintains a disciplined approach to capital allocation, preferring to keep a "loaded gun" of cash ready for rare, high-quality acquisition opportunities. Finally, Buffett underscores the importance of managerial integrity, praising the talented leaders who run his subsidiaries with autonomy and expertise.
