A stock screener is a digital tool or software that enables investors and traders to filter and sort stocks based on specific, user-defined metrics. By setting certain criteria, such as market capitalization, dividend yield, or price-to-earnings ratio, users can identify trading instruments that meet their investment strategies and goals.
How Do Stock Screeners Work?
Criteria Selection
Stock screeners operate by allowing users to input various criteria that they consider important for their investment decisions. Common criteria include:
- Market Capitalization: The total market value of a company’s outstanding shares.
- Price-to-Earnings (P/E) Ratio: A valuation ratio of a company’s current share price compared to its per-share earnings.
- Dividend Yield: A financial ratio that shows how much a company pays out in dividends each year relative to its stock price.
- Volume: The number of shares traded within a particular period.
- Sector and Industry: Classification of companies based on their business activities.
Database Filtering
Once the criteria are selected, the stock screener filters through a vast database of stocks, narrowing down the list to those that match the input conditions. Advanced screeners may allow for multiple layers of criteria, combining different financial ratios, growth metrics, and technical analysis indicators.
Output Presentation
The filtered list of stocks is then presented to the user, often with an ability to sort and further analyze the results. Some screeners offer additional features such as alerts, historical data, and integration with trading platforms.
Types of Stock Screeners
Fundamental Screeners
These focus on financial health metrics such as earnings, revenue, and expenses. Fundamental screeners help investors identify undervalued or overvalued stocks based on intrinsic valuation models.
Technical Screeners
Technical screeners prioritize price patterns, volume, and other indicators to determine potential entry and exit points. These are often employed by day traders and technical analysts.
Combined Screeners
These offer a hybrid approach, incorporating both fundamental and technical analysis to provide a comprehensive evaluation of stocks.
Example Usage
Consider an investor looking for growth stocks with the following criteria:
- Market Capitalization: Greater than $2 billion
- Revenue Growth: More than 20% annually for the last three years
- P/E Ratio: Less than 30
- Dividend Yield: More than 1%
By inputting these metrics into a stock screener, the investor receives a focused list of potential investment opportunities that match their growth-oriented strategy.
Sample Screen
A user proceeds to input the criteria:
1Market Capitalization: >$2B
2Revenue Growth: >20%
3P/E Ratio: <30
4Dividend Yield: >1%
The stock screener might output stocks such as:
- Company A: Market Cap $5B, Revenue Growth 22%, P/E Ratio 28, Dividend Yield 1.2%
- Company B: Market Cap $10B, Revenue Growth 25%, P/E Ratio 25, Dividend Yield 1.5%
Historical Context and Evolution
The concept of stock screening originated with manual methods in the early 20th century, where analysts painstakingly reviewed financial statements. With the advent of computers and the internet, stock screeners evolved rapidly, becoming sophisticated tools integrated with real-time data feeds and complex algorithms.
