State Street Global Advisors (SSgA) is to use five Dow Jones Wilshire US Size and Style indexes as the basis of nine new exchange-traded funds (ETFs).

SSgA has also switched the underlying indexes of four existing ETFs to the Dow Jones Wilshire Style Indexes from the Dow Jones US Style Indexes, meaning that SSgA now offers ETFs on the full set of Dow Jones Wilshire Size and Style Indexes.

The new ETFs, which began trading today on the American Stock Exchange last week, combined with the four that switched indexes, capture the top 2,500 US stocks in the Dow Jones Wilshire 5000sm Composite Index, according to size and style.

The underlying-size indexes for the new ETFs are the Dow Jones Wilshire US Large-Cap Index, Dow Jones Wilshire US Mid-Cap Index and the Dow Jones Wilshire US Small-Cap Index. Additionally, the new Dow Jones Wilshire US Mid-Cap Growth and Dow Jones Wilshire US Mid-Cap Value ETFs will complement the transitioned Dow Jones Wilshire US Large-Cap Growth, Dow Jones Wilshire US Large-Cap Value, Dow Jones Wilshire US Small-Cap Growth and Dow Jones Wilshire US Small-Cap Value ETFs.

"The Dow Jones Wilshire Index family is the broadest measure of the US stock market," says Michael A Petronella, president, Dow Jones Indexes/Ventures. "State Street Global Advisor's decision to issue ETFs based on the full suite of Dow Jones Wilshire US Style Indexes ensures that best practices and methodology for measuring these categories are being utilized."

The four existing-style ETFs -- previously based on the Dow Jones US Large-Cap Growth Index, Dow Jones US Large-Cap Value Index, Dow Jones US Small-Cap Growth Index and Dow Jones US Small-Cap Value Index -- switched late last month to the Dow Jones Wilshire US Large-Cap Growth Index, Dow Jones Wilshire US Large-Cap Value Index, Dow Jones Wilshire US Small-Cap Growth Index and Dow Jones Wilshire US Small-Cap Value Index.

"The introduction of five new style-based ETF products derived from the Dow Jones Wilshire Index family enhances SSgA's ETF offerings and brings customers a full range of investment tools to meet their financial goals," says Jim Ross, co-head of SSgA's Advisor Strategies unit. "By adopting the remaining Dow Jones Wilshire US Style Indexes for our existing style-based street TRACKS ETFs, we have ensured that our customers can access every segment of the US equity market across a complete portfolio of investment styles."  

The Dow Jones Wilshire U.S. Indexes family comprises the Dow Jones Wilshire 5000 Composite Index, Dow Jones Wilshire RESI Index, Dow Jones Wilshire REIT Index, Dow Jones Wilshire US Industry Indexes and Dow Jones Wilshire US Style Indexes.

Dow Jones Wilshire Indexes are available on market-data vendor platforms -- many in real-time format -- and on the Dow Jones Indexes (www.djindexes.com) and Wilshire Associates (www.wilshire.com) Web sites. Style history is available to 31 December 1998. The Dow Jones Wilshire 5000 Composite Index is calculated and distributed by Dow Jones Indexes under an agreement between Dow Jones & Company and Wilshire Associates Incorporated.
