Warren Buffett, Investing’s Philosopher King

Now that Warren Buffett, the philosopher king of modern investing, has announced that he will step down as Berkshire Hathaway Inc.’s chief executive officer at the end of the year, it’s a good time to marvel again at his career.

Any discussion of Buffett must start with his astonishing track record. He is the greatest investor of all time. No one has even come close to what he has achieved, and I doubt anyone ever will.

Buffett learned his craft from the great Ben Graham, the father of security analysis, first as Graham’s student at Columbia Business School in the early 1950s and later working for him. In the ensuing decades, he expanded on what he learned from Graham, deepening his investing skills and fine-tuning his personal code for work and life that guided his six decades at Berkshire. Investors often talk about applying life lessons to investing; Buffett brought investing to life.

Investing is a notoriously difficult endeavor, and most people who attempt it, lay or professional, are better off in an S&P 500 index fund – an approach Buffett has long recommended. The few who beat the market might do so for a short time or by a modest amount. Legendary stock pickers who are sometimes placed in the same pantheon with Buffett were mostly at the right place at the right time.

Buffett’s record stands alone, a testament to his unusual skill and approach. The market value of Berkshire’s shares grew by an annualized 19.9% a year over six decades from 1965 to 2024, compared with a return of 10.4% a year for the S&P 500 over the same time, including dividends, according to the company. Even after accounting for the maestro’s penchant for value and quality investing, two styles of stock picking that have beaten the market historically, and the leverage inherent in Berkshire’s insurance business that amplifies his investing returns, he still beats the market.

Yet Buffett’s contributions go well beyond what shows up on a performance chart. He has spent decades trying to demystify investing and educate investors, primarily through his artfully written annual shareholder letters, a must read for any aspiring investor. There, he imparts timeless Midwestern wisdom and acknowledges his mistakes in painstaking detail, a practice practically unheard of on Wall Street. His annual letters have become so widely read that many chief executives now pen a letter of their own, but none of the imitators top the original.
