Warren Buffett turned $10,000 into $29,960,000 over 50 years without ever touching cryptocurrency, without ever buying a lottery ticket and without ever making a trade he didn't understand. Berkshire Hathaway Research Memorandum No. 28 is the internal document that breaks down exactly how he did it - and why 95% of investors will never replicate it. From 1965 to 2024 Berkshire Hathaway achieved 19.8% annualized return. The S&P 500 returned 10.2%. That gap compounded over 59 years turned $1 into $38,223 inside Berkshire and $1,056 in the index. Same starting point. One decision separated them by $37,167. Here's what the document shows - Buffett operates on five rules that never changed in 60 years. Preserve capital first - a permanent loss cannot compound. Invest with a margin of safety and buy businesses worth $1 for $0.60. Focus only on what you understand and walk away from everything else. Think in decades, not quarters. The valuation model behind every Berkshire position is one equation. V = sum of FCF / (1+r) + terminal value. Free cash flow discounted to present value. If the market price is significantly below V there is a margin of safety. If not, Buffett walks away. He has walked away more times than he has bought. Now watch the compounding curve [Fig. 1] - $10,000 invested for 50 years. At 5% it becomes $114,700. At 8% it reaches $4,660,000. At 10% it climbs to $11,740,000. At 12% it becomes $29,960,000. The difference between 5% and 12% is not 7%. Over 50 years it is $29,845,300. That is what compounding does to a small number in a long time. The recommended allocation for a first $100,000 profit [Fig. 3] - 40% into broad index funds as the core long-term growth engine. 20% into individual high-quality stocks for additional return potential. 15% into real estate for income and diversification. 10% into your own business - highest potential, highest risk. 10% held in cash and short-term bonds for flexibility and future opportunities. 5% into education and private investments. The document lists lottery tickets in the comparison table as a mathematically losing investment with negative expected value. Buffett has never bought one. "The best investment is often in your own knowledge and skills." Berkshire Hathaway wrote that in the conclusion. Buffett has been saying it since 1965.
