Talk:US completion index returns

The use of dispersion may be too technical for new investors to understand. I added "variation" in the hope of clarifying. Please review the introduction carefully.

I added direct links to the completion indexes (indices - usage is inconsistent, but indexes is used on the web sites.) The Wilshire 4500 Completion Index appears to be new (versus the Wilshire 4500 Index). Do we need to change any of the other pages? --LadyGeek 17:16, 11 July 2011 (EDT)
