Warren Buffett spent 60 years proving that assumption wrong, building one of the greatest fortunes in history through patience and simplicity rather than complexity. What Warren Buffett actually recommends for most investorsBuffett has made his position clear in shareholder letters, interviews, and annual meetings going back years. At Berkshire's 2021 annual meeting, he said: "In my view, for most people, I think that the best thing to do is buy an S&P 500 index fund." Why the Vanguard S&P 500 ETF fits exactly what Buffett describesVanguard S&P 500 ETF (VOO) tracks the S&P 500, charges 0.03% a year, and has grown to more than $950 billion in assets. That's what Buffett means when he says low cost, and that's why he keeps naming Vanguard specifically when people ask which fund.
