Excellent book.

Buffett recommends putting 90% in an S&P 500 index fund. He specifically identifies Vanguard’s S&P 500 index fund. Vanguard offers both a mutual fund (VFIAX) and ETF (VOO) version of this fund. He recommends the other 10% of the portfolio go to a low cost index fund that invests in U.S. short term government bonds
