Wilshire’s Style Indexes are benchmarks used to evaluate the performance of active managers. They were created in 2005 by separating the Wilshire 5000 into four capitalization groups (Large, Small, Mid and Micro), and then dividing the Large, Small and Mid-cap issues by float adjusted capitalization equally into growth and value indexes. Growth and value is defined by looking at six factors: Projected Price-to-earnings ratio, projected earnings growth, price-to-book ratio, dividend yield, trailing revenue growth and trailing earnings growth. The Indexes’ purpose is to help fund sponsors measure the performance of managers relative to their respective investment management style.
