Market Cap Universes

The Market Cap Universes are formed from the top 99.5% of the "Investable Universe" of stocks measured by total Market Cap. The smallest companies that fall into the 0.5% of the total "Investable Universe" Market Cap are dropped to avoid penny stocks with high trading volumes.

The "Investable Universe" is defined as stocks which:

trade on NYSE, NASDAQ or AMEX;
are not ADRs, Preferred shares, or tracking stocks/ETFs;
and are among the top 75% of the companies based on its 3 month average trading volume.

The resulting list of stocks, the investable universe, is then sorted by market capitalization. The following classification is then made:

The top 79% companies are assigned to the LargeCap Universe
The stocks that fall between 79% and 93.5% are assigned to the MidCap Universe
The stocks that fall between 93.5% and 98.5% are assigned the SmallCap Universe
The stocks that fall between 98.5% and 99.5% are assigned the MicroCap Universe

The Market Cap universes are reconstituted Quarterly at the end of each quarter. The universes do not have survivorship bias. The following Market Cap based universes are available:

Universe	Code	Approx. Number Stocks	Approx. Market Cap Range
