2008 Equity Market
So 2008 marks the end of a unique 10 year period: in the last 60 years (on a rolling 10 year basis) it was the only time the S&P 500 lost money.
2008 also marked the 4th year in the last 9 that the S&P 500 posted a negative total return, joining 2000, 2001 and 2002.
Since 1936, the average annual total return of the S&P 500 is 10.02% and the standard deviation is 18.17%. In other words: 68% of the time, one would expect the S&P 500 to return between -8.15% and 28.19%.
In the last 20 years, the average return is 8.33% and the standard deviation is 19.78%. More volatility, less return.
