Dow jones

Methodology Overview
The Dow Jones Select MicroCap Index is designed to represent microcap stocks trading on the New York Stock Exchange, American Stock Exchange and Nasdaq that are comparatively liquid and have strong fundamentals relative to the microcap segment as a whole.
DEFINING THE SELECTION UNIVERSE
All stocks traded on the NYSE are ranked by full market capitalization, and then are divided into deciles containing equal numbers of securities. Deciles nine and ten are defined as microcaps.
All stocks traded on the NYSE, Amex and Nasdaq whose market capitalizations are within or below the microcap range defined by the NYSE stocks are included in the selection universe.
STOCK SELECTION The index composition is determined by selecting stocks from the universe based on size, trading volume and financial indicators.
Eliminated from the selection universe are any securities that do not meet all three of the following criteria:
Within the top 1,000 stocks by full market capitalization.
Within the top 1,000 stocks by three-month dollar volume
Within the top 1,500 stocks by one-month dollar volume
Excluded are stocks that rank within the bottom 20% of the filtered selection universe based on any one of the following factors:
Trailing P/E ratio (highest are excluded)
Trailing price/sales ratio (highest are excluded)
Per-share profit change for the previous quarter (lowest are excluded)
Operating profit margin (lowest are excluded)
Six-month total return (lowest are excluded)
Individual securities for which financial ratios or return data are not available are not subjected to the corresponding screens.
REVIEW FREQUENCY The index composition is reviewed annually, in August. Shares and float factors are updated quarterly, in March, June, September and December.
HISTORICAL DATA AVAILABILITY Historical index values are available daily back to August 31, 1992. The base value of the index is set at 100 as of that date.
WEIGHTING The index is weighted based on float-adjusted market capitalization back to May 3, 2004. Prior to that date the index is weighted based on full market capitalization
