Stock Market Returns by Asset, 1926-1995

Stocks = S&P500; Bonds = 20 year Treasury bond

Historically, here is how various combinations of stocks and bonds would have performed, with the number of down years total, the lowest and highest annual return, and the average annual return. As expected, the higher the proportion of stocks, the greater the total return, but the greater maximum 12 month loss, and the greater the number of losing years.
