S&P 500 30-Year Rolling Total Returns

This is the last installment of S&P 500 Index Rolling Returns series.

The average 30-year rolling total return for the S&P 500 starting with 1926, is 2,478% or 11.21% annualized (geometric mean). There were several 30-year periods that had annual returns between 8% and 10%. Also, these numbers are not adjusted for the CPI, which would have a significant negative impact on the end results (perhaps another AFM series?).
