What Is a Stock Screener

A stock screener is a tool that filters thousands of stocks based on criteria you define. Instead of manually reviewing every stock, you set your parameters and the screener shows you only the stocks that match.

Why Use a Stock Screener

There are over 6000 stocks listed on US exchanges alone. No human can analyze all of them. A screener narrows the field to your best opportunities in seconds.

Key Screening Criteria

Technical criteria include price above or below moving averages, RSI in oversold or overbought territory, volume spikes showing unusual activity, 52-week high and low proximity, and percentage change over different periods. Fundamental criteria include market capitalization, price-to-earnings ratio, revenue growth, profit margins, and debt levels.

Popular Screening Strategies

Momentum Strategy filters for stocks up 20 percent or more in the last month with increasing volume. Oversold Bounce filters for stocks with RSI below 30 that are still above their 200-day moving average. Breakout Scanner filters for stocks trading near their 52-week high with above-average volume.
