The iShares Russell 2000 Value Index Fund (Ticker: IWN) seeks investment results that, before fees and expenses, correspond generally to the performance of the Russell 2000 Value Index, which is a style-set of the small cap Russell 2000 Index. Companies in the index are ranked by two variables: the price-to-book ratio and the I/B/E/S forecast long-term growth mean. Variables are combined to create a composite value score (CVS) for each stock. Rank the stocks by their CVS and apply a algorithm to the distribution to determine style membership weights. 70% are classified as all value or all growth and 30% are weighted proportionately to both value & growth.
