On March 17th, 2005, Dow Jones Indexes and Wilshire Associates completed the second phase of the Dow Jones Wilshire Index relationship - the release of the Dow Jones Wilshire U.S. Style Indexes. The calculation of Wilshire Style Indexes and Wilshire Target Indexes ceased July 31, 2006. Click here to view suggested replacement indexes.

In 1986, Wilshire was the first consulting firm to introduce style indexes. Now called the Target Indexes, they are comprised of stocks with concentrated growth or value characteristics. Growth and value are defined by looking at multiple factors, including price-to-book and projected price-to-earnings ratios, sales and earnings. They differ from the Wilshire Style Indexes in that many stocks are excluded from the Target Indexes because they are not measured to be highly growth or highly value. In a way, they are ‘high octane’ style indexes that are popular for investors wishing to measure or invest passively in style categories. They are not recommended as performance benchmarks for most active managers whose style is generally not as concentrated as the Target Indexes.
