The Wilshire Returns: Wilshire Associates to Market the Original Wilshire 5000 Index(sm) and the Wilshire Index Family That Spans the Globe

Santa Monica, California, UNITED STATES

SANTA MONICA, Calif., April 1, 2009 (GLOBE NEWSWIRE) -- Wilshire Associates Incorporated, a leading global independent investment consulting and services firm, today announced that it will once again market the original Wilshire 5000 Total Market Index(sm) which was developed in 1974 by its Chairman and Chief Executive Officer, Dennis A. Tito.

As of April 1, only Wilshire(r) will have the authorization to provide history back to December 31, 1970 for the original Wilshire 5000(sm) which will be broadcast in real time to data vendors using the symbol W5000. The Wilshire family of indexes spans the globe and includes U.S. Size/Style, U.S. and Global Real Estate, as well as indexes representing 65 countries and regional, developed and emerging markets indexes.

"Now widely considered the best way to track the U.S. equities market and estimate market value changes, the Wilshire 5000 was not developed to create licensed products, generate media coverage or support other indexes," noted Tito. "Beginning with the Wilshire 5000, each Wilshire Index was created to assist our investment professionals and clients to measure, understand and explain the market. That is why the Wilshire Index family reflects Wilshire's performance measurement heritage as the right way to measure the market," he said.

"The rules governing the construction of the Wilshire Indexes were not driven by what was easy, sampled, sounded exciting, or imposed arbitrary rules and cutoffs. Each Wilshire index has a reason as to why it was created to measure a section of the market," Tito commented. "For example, in 1974, we were calculating betas and developing asset allocation tools. We found that a market proxy of 500 stocks missed a significant part of the investment performance story and fell short as a basis for risk measurement and diversification. We had the data and the performance software, and created the Wilshire 5000," Tito stated.

"Several years later it became useful to separate the Wilshire 5000 into two parts. We eliminated the 500 stocks in the S&P 500 Index and what was left became a new index, called the Wilshire 4500(sm)," said David Hall, senior managing director of Wilshire Associates and head of Wilshire Equity Analytics, a division of Wilshire Analytics, the investment technology business of the firm. "This greatly assisted money managers and fund sponsors in more effectively and accurately benchmarking portfolio performance. Continuing on that track, in 1986, Wilshire introduced a multi-factor style measurement metric and associated style indexes to quantify portfolios' growth, value and size characteristics based on its holdings," he added.

"Wilshire's number one requirement for all Wilshire Indexes is that they are the best measure of the market. We know we have achieved this goal as our research confirms it and index providers continue to follow our lead," said Robert Waid, vice president, Wilshire Associates, and head of Wilshire Indexes. "Our mandate as an index provider is to measure and describe the market in ways that are meaningful and important to investment professionals worldwide. We are confident that the Wilshire Index Family provides the best measure of equities markets spanning the globe," Waid concluded.
