A tool that investors and traders can use to filter stocks based on user-defined metrics. Stock screeners are offered on many websites and trading platforms, and they allow users to select trading instruments that fit a certain profile set of criteria. For example, users are able to screen for stocks by data including price, market capitalization, P/E ratio, dividend yield and 52-week price change percentage, average volume and average five-year return on investment (ROI). Some trading platforms and software allow users to screen using technical indicator data. For example, one could filter for stocks that are trading above their 200-day moving average or whose Relative Strength Index (RSI) values are between a specified range.
