    They use the same indexes but are allowed to change the contents that affect each index. If housing went up 30%, remove housing from the index.

      Pretty sure this is how the S & P or the Dow Jones Industrial Average works too. They just hot swap companies into and out of the index, based on their performance, to arrive at a certain number.
