Prussell Universes
These universes are designed to mimic the Russell indices. They are not the official Russell universes. We created them following their guidelines as much as possible.
The Prussell Universes are formed by selecting the top 3000 stocks of the "Investable Universe" of stocks measured by total Market Cap. The top 3000 companies represent a significant portion of the domestic US market.
The "Investable Universe" is defined as stocks which:
- trade on NYSE, NASDAQ, or AMEX;
- are not ADRs, Preferred shares, tracking stocks/ETFs;
- are not financial vehicles such as royalty trusts and investment companies;
- are not Berkshire Hathaway;
- trade above 1.0 on the last trading day before reconstitution.
The resulting list of stocks, the investable universe, is then sorted by market capitalization. The following classification is then made:
- The top 1000 companies are assigned to the Prussell 1000
- The next 2000 companies are assigned to the Prussell 2000
- The entire list of 3000 companies are assigned to the Prussell 3000
The Prussell universes are reconstituted annually and do not have survivorship bias. If a stock moves to the OTC exchange after reconstitution dates,
it is excluded and not replaced.
Securities that leave the index between reconstitution dates, for any reason including mergers, acquisitions, or similar corporate action are not replaced.
Therefore, the number of securities in the index over the year will fluctuate according to corporate activity.
The following Market Cap based universes are available:
| Universe | Code |
| Prussell 1000 | Prussell1000 |
| Prussell 2000 | Prussell2000 |
| Prussell 3000 | Prussell3000 |
Example To screen for all stocks belonging to the Prussell 2000 Universe enter the following rule:

Deprecated Prussell Universes
The following are previous versions of our Russell universes. There are two differences with the above: they do not exclude MLPs and do not exclude stocks that move to the OTC after reconstitution.
