If you are not a professional investor and don't want to worry about your investment every day, buy an index fund.
In 2007, Buffett once again recommended index funds: "For the vast majority of small and medium-sized investors who don't have time to do sufficient stock research, low-cost index mutual funds may be the best choice for them to invest in the stock market."
? "I often recommend low-cost S&P 500 index funds, but only a few modest friends will believe me."
Buffett admitted in an interview that he advised his wife to buy index funds after his death: if she holds the S&P 500 index fund, she will have enough liquidity to provide the needed funds. For those who want to get the least worry, index funds are the best investment.
Buffett also praised Jack Bogle, founder of Vanguard, at the shareholders' meeting, saying that stock selection was a waste of time and money. The old man said, "Jack Bogell has probably done more for American investors than anyone else."
