Big, Mid, and Small Cap Performance, from Philip J. McDonnell
A random look at S&P web site shows that the 10 year performance of big cap, mid cap and small caps are roughly as follows:
Big (500) 3% Mid (400) 10% Small(600) 10%
The big caps have significantly under performed the other sectors of the market. Even REIT's have had about a 12% return which seems surprising given the real estate market.
However the question that leaps to mind is why is there such a disparity between big caps and the broader market?
