What Is Stock Screener?

A stock screener is an analytical tool that allows investors to filter the universe of publicly traded stocks based on specific criteria and parameters. Common screening criteria include market capitalization, price-to-earnings ratio, dividend yield, revenue growth, profit margins, debt-to-equity ratio, relative strength, sector, and many other fundamental and technical indicators. Stock screeners are available from financial data providers (Finviz, Yahoo Finance, Morningstar), brokerage platforms (Fidelity, Schwab, TD Ameritrade), and specialized services (Stock Rover, Zacks). Screening is a top-down approach that narrows thousands of stocks to a manageable list of candidates for deeper analysis. Famous investors have used screening methodologies extensively — Benjamin Graham's value criteria, William O'Neil's CAN SLIM methodology, and Joel Greenblatt's Magic Formula are all screener-compatible strategies. While screeners are powerful for idea generation, they should be a starting point for research rather than a final investment decision.

  • 2Using a momentum screener, a trader identified stocks hitting 52-week highs with above-average volume.
