- [Liquidity Universes](https://www.quantconnect.com/docs/v2/writing-algorithms/universes/equity/liquidity-universes.md): A liquidity universe lets you select a set of stocks with the greatest dollar volume in the market.
- [Fundamental Universes](https://www.quantconnect.com/docs/v2/writing-algorithms/universes/equity/fundamental-universes.md): A fundamental universe lets you select stocks based on corporate fundamental data from Morningstar®.
- [Morningstar Migration](https://www.quantconnect.com/docs/v2/writing-algorithms/universes/equity/morningstar-migration.md): Morningstar replaced the feeds behind the US fundamental dataset, which changes values, reporting dates, and coverage in your backtests.
- [ETF Constituents Universes](https://www.quantconnect.com/docs/v2/writing-algorithms/universes/equity/etf-constituents-universes.md): You can select a universe based on the constituents of an ETF, and then you can further filter your universe down with fundamentals.
- [Chained Universes](https://www.quantconnect.com/docs/v2/writing-algorithms/universes/equity/chained-universes.md): Chained universes let you combine universes together to fetch fundamental and alternative data on a specific subset of assets.
