Berkshire Hathaway Annual Shareholder Letters (1965–present)

by Warren Buffett

Summary

Warren Buffett’s shareholder letters, compiled from 1965 to 2012, argue that long-term intrinsic value creation—measured by growth in per-share book value and operating earnings—outweighs short-term market fluctuations or stock price movements. The letters detail Berkshire’s acquisition criteria, such as buying businesses with durable competitive advantages (“moats”), honest management, and predictable earnings, while avoiding debt and speculative investments. Buffett emphasizes the importance of retaining earnings to generate future value, the folly of timing markets, and the necessity of a rational capital allocation policy. Readers learn how to evaluate businesses through a lens of economic reality rather than accounting conventions, and how to maintain discipline during market cycles. The collection serves as a practical manual for value investing, corporate governance, and long-term wealth building, grounded in decades of real-world decisions and results.

  • FloatInsurance premiums collected before claims are paid, providing low-cost or negative-cost capital for investments when underwriting is profitable.
