I noticed that Tom uses ^DWCP instead of ^DWCPF. The F has to do with "free-float" adjusted. (has adjustment for market capitalization??)

I'm already saying more than I understand. Anyway thought it was interesting.

A quote from their press release:

"The Dow Jones Wilshire indexes will be free-float weighted, using the existing Dow Jones Indexes free-float methodologies that remove corporate shares that are not available for public trading. "

In other words, they're both market-cap weighted but the float factors used in constructing dwcpf adjust the index by removing insider-owned shares. The full-cap weighted index, dwcp, reflects ALL shares. They almost the same ( they're identical prior to July 2004), but dwcpf is probably closer to the TSP S fund.

Thanks! That actually makes sense.
