Past performance may not be indicative of future results. The S&P 500 is an unmanaged index of 500 widely held stocks that is generally considered representative of the U.S. stock market. Keep in mind that individuals cannot invest directly in any index.

What are my conclusions of this exercise? First, at least in my lifetime, 2008 is the outlier in the data series. Second, excluding 2008 doesn't change the results that much. All it does is take both periods from a small loss to a small gain. Third, the data by itself doesn't guide me to take any specific action outside of my normal portfolio rules. I'm afraid this may be an event hyped for the news cycle but one that, historically speaking, should not have any meaningful impact on your investments.
