We Think of Ourselves as Business Owners, Not Stock Traders
One of the first letters establishing Berkshire's modern format after Buffett took control. He explicitly articulates the investment philosophy that would define Berkshire for decades: stocks are fractional ownership interests in real businesses, not tradeable symbols. Success is measured not by stock price but by growth in per-share intrinsic value.
"We prefer a small piece of a wonderful business to owning the whole of a mediocre one."
Graham's Mr. Market Parable — The Investor's Most Useful Mental Framework
Written during the year of Black Monday's market crash, this letter contains Buffett's most famous elaboration of Graham's Mr. Market concept. He explains why volatility is not risk but opportunity — as long as you have clear judgment about the intrinsic value of what you own. It remains the definitive articulation of why price swings should be exploited, not feared.
"The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company."
The Most Important Investment Question: How Wide Is the Moat?
This letter systematically articulates the moat concept that would become foundational to all later competitive-advantage analysis. Buffett explains that his first question when evaluating any investment is: "How wide is this company's moat, and how durable is it?" He uses Coca-Cola and Gillette as case studies for why he's willing to pay a fair price for a genuine moat.
"In business, I look for economic castles protected by unbreachable moats."
Buying America in a Crisis: Seeing Opportunity in Fear
During the depths of the global financial crisis, Buffett published his famous New York Times op-ed "Buy American. I Am." This year's letter details the logic behind crisis investing: when maximum fear creates maximum pessimism, it's precisely when investors with clear judgment about business value should act most decisively. He put $15 billion to work in the fall of 2008 alone.
"In the 20th century, the United States endured two world wars, a dozen or so recessions. Yet the Dow rose from 66 to 11,497."
Why Stocks Beat Gold: The Power of Productive Assets
This letter features a thought experiment comparing three asset classes: gold, a farm, and equities. Buffett demonstrates why only productive assets — farms and businesses — can genuinely protect and grow purchasing power in an inflationary environment, while non-productive assets like gold and cash are gradually eroded by time.
"Productive assets will grow in nominal value because inflation raises the prices of all goods and services."
Bet on America: It Has Never Been the Wrong Move
Against a backdrop of unusual public pessimism, Buffett makes his most forceful argument for long-term confidence in American enterprise. He surveys 240 years of American economic progress and argues that everyone who bet against America — across wars, panics, depressions, and political upheaval — lost. The simplest strategy: own a piece of American business and be patient.
"American business — and consequently a basket of stocks — is virtually certain to be worth far more in the years ahead."
The Overlooked Engine: Retained Earnings Fuel Compounding
This letter revisits a theme Buffett has emphasized for decades: the extraordinary power of retained earnings. He explains why one of Berkshire's core advantages is that its subsidiaries can reinvest large portions of their earnings at high rates of return — without needing to raise capital from shareholders or banks. Retained earnings are the fuel that powers the compounding machine.
"Retained earnings allow our businesses to expand without needing to tap shareholders or bankers. This is the heart of our compounding machine."
