Who is Warren Buffett?
Warren Buffett, one of the most legendary investors in history, has achieved remarkable success through his investment philosophy and methodology. His views on diversification, a concept widely regarded as essential for risk management by many experts and Nobel laureates, are unique and challenging.
Buffett’s Stance on Diversification
In the 1996 Berkshire Hathaway annual meeting, Buffett famously stated, “Diversification is protection against ignorance. It makes very little sense for those who know what they’re doing.” He further emphasized, “If you don’t understand the businesses, diversify. But if you do, why have 50 when three will suffice?”
Buffett’s Investment Philosophy
Buffett views the market as a collection of real businesses rather than interchangeable assets. When he invested in Coca-Cola, it wasn’t for its brand or taste, but for its franchise model, global distribution, and cash flow generation capabilities. However, he acknowledged that not many such businesses exist, making diversification among 50 companies impractical.
Why Buffett’s Approach Works
Buffett’s strategy is analytical, not speculative. Understanding a business deeply—its debt, margins, and crisis resilience—provides better protection than a portfolio of 50 poorly understood companies. His method involves holding stocks for decades, unaffected by short-term market noise.
Contextualizing Buffett’s Approach
Buffett doesn’t invest like most individuals. Berkshire Hathaway’s internal cash flows allow it to sustain investments without liquidity pressure. Unlike many investors, Buffett doesn’t sell during market downturns; instead, he buys. He restructures or injects capital into struggling companies rather than abandoning them. His portfolio is an interconnected ecosystem of businesses, not just a list of companies.
Implications for Other Investors
Buffett’s approach doesn’t negate the value of diversification. However, using it as a substitute for thorough analysis is not recommended. If you can identify and maintain businesses with structural advantages, concentration is viable. Otherwise, diversification remains a tool for those who lack the capacity or willingness to dedicate decades to business study.
Buffett’s Own Investment Plan
In his will, Buffett advised that 90% of his wealth for his wife should be invested in an S&P 500 ETF, while the remaining 10% should be in long-term U.S. Treasury bonds. This recommendation isn’t arbitrary; it reflects the understanding that, for those without his analytical capabilities or long-term horizon, a concentrated portfolio isn’t practical. Here, diversification is not a virtue but a tool for those unable or unwilling to dedicate decades to business study.
