This spring saw the rebranding of two major Dow Jones indexes product lines.

Perhaps most importantly, the index provider’s agreement with Wilshire Associates was terminated on March 31. For several years, the two index providers jointly marketed an index family that included the rebranded version of the well-known Wilshire 5000 Index, which represents nearly all the listed stocks in the U.S.

Both parties have returned to calculating their own indexes, with the Dow Jones Wilshire index family rebranded as the Dow Jones Total Stock Market index family and Wilshire Associates’ indexes once again marketed under its own brand name. The jointly marketed indexes were identical as of April 1, but will likely diverge going forward as the two different providers interpret rules separately and modify the methodologies over time, a Wilshire representative said.

More recently, the Dow Jones – AIG Commodity Index changed its name to the Dow Jones – UBS Commodity Index as of May 7, following the acquisition of some of AIG’s assets by UBS.

The index’s methodology remains exactly the same, but new suggested ticker symbols reflecting the name change have been generated for the main index and its subindexes. Dow Jones is publishing parallel sets of indexes under the new and old ticker symbols for 30 days before phasing out the old symbols; the index values for both sets of symbols are exactly the same.
