As I shared in the chart, it is easy to see that the New York Composite Index and the S&P 500 have traded in lock-step over the past 15 years. In 1999, the NYSE traded sideways for a few months while the S&P 500 continued to push higher. After this period of underperformance by the NYSE, both declined in value.
Of late the NYSE is lagging the 500's performance at (3). Humbly, I don't know why the NYSE is lagging the 500 index of late. I do respect the message it would be sending if this underperformance would continue!
