Warren Buffett's Endorsement of Vanguard S&P 500 ETF for Long-Term Investing Success

Warren Buffett recommends the Vanguard S&P 500 ETF (VOO) as a simple and effective investment strategy for most people. He believes that a low-cost index fund, such as VOO, will outperform a majority of amateur and professional managed money over the long term. Buffett has also mentioned in his will that he would invest 90% of his wife's inheritance in VOO. His endorsement of VOO is based on the idea that most people are not financial market experts and should stick to a broad index like the S&P 500.
