How to Set Up A Stock Screener?

6 minutes read

Setting up a stock screener involves narrowing down the universe of stocks to find opportunities that match specific criteria. To begin, define your investment goals and criteria such as market capitalization, sector, price-to-earnings ratio, and dividend yield. Choose a stock screening tool that meets your needs and has the features you require. Input your criteria into the stock screener, adjusting as needed to refine your search results. Evaluate the output to identify potential investment opportunities that align with your goals. Regularly update and adjust your screening criteria to stay ahead of market trends and make informed investment decisions.


What criteria should I consider when setting up a stock screener?

When setting up a stock screener, consider the following criteria:

  1. Market capitalization: Define the size of companies you are interested in investing in by specifying a range of market capitalizations.
  2. Industry/sector: Filter stocks based on their industry or sector to focus on a specific area of interest or sector that you believe will perform well.
  3. Price/Earnings ratio (P/E): Look for stocks with a low P/E ratio to find undervalued opportunities or filter for high P/E ratios for growth stocks.
  4. Dividend yield: If you are interested in income-generating stocks, specify a minimum dividend yield to filter for dividend-paying stocks.
  5. Earnings per share (EPS) growth: Look for stocks with consistent or accelerating EPS growth to identify companies with strong fundamentals and potential for future growth.
  6. Price/Book value ratio (P/B): Filter for stocks with a low P/B ratio to identify potentially undervalued stocks relative to their book value.
  7. Technical indicators: Consider adding technical indicators such as moving averages, RSI, or MACD to identify trends or potential entry/exit points for trading.
  8. Analyst ratings: Include criteria such as analyst ratings, price targets, and recommendations to get insight from professionals in the field.
  9. Financial metrics: Consider including criteria such as revenue growth, profit margins, debt levels, and return on equity to analyze a company's financial health and performance.
  10. News and events: Stay updated on current news, events, and market trends that could impact stock prices and performance.


Overall, customize your stock screener based on your investment goals, risk tolerance, and investment strategy to identify stocks that align with your criteria and preferences.


What is the difference between a stock screener and a stock filter?

A stock screener and a stock filter are both tools used by investors to narrow down and filter through a large number of stocks to find potential investment opportunities. However, there are some differences between the two:

  1. Stock Screener:
  • A stock screener is a tool that allows investors to set specific criteria or parameters, such as market capitalization, industry sector, P/E ratio, etc., to screen and filter through a large database of stocks to identify potential investment opportunities that meet their specific requirements.
  • Stock screeners typically generate a list of stocks that match the specified criteria, providing investors with a shortlist of potential investment opportunities.
  • Stock screeners are often more detailed and customizable, allowing investors to set multiple criteria and refine their search to find stocks that meet their investment objectives.
  1. Stock Filter:
  • A stock filter is a more basic tool that allows investors to apply simple filters or search terms to narrow down a list of stocks based on specific criteria, such as price range, volume, or dividend yield.
  • Stock filters are usually less customizable and less detailed compared to stock screeners, as they typically only offer a limited set of filters or search options.
  • Stock filters are often used for quick searches or to scan through a large number of stocks based on basic criteria, without the need for detailed analysis or customization.


In summary, the main difference between a stock screener and a stock filter lies in their level of customization and complexity. Stock screeners are more detailed and customizable tools that allow investors to set specific criteria and refine their search to find potential investment opportunities, while stock filters are simpler tools that offer basic filters or search options to quickly narrow down a list of stocks.

What are the most common mistakes to avoid when using a stock screener?

  1. Using only one factor: Many investors make the mistake of using only one screening factor, such as price or volume, to identify stocks to invest in. It's important to consider a combination of factors, including fundamental and technical indicators, to get a more comprehensive picture of a stock's potential.
  2. Ignoring the importance of screening criteria: It's essential to carefully select the criteria you use to screen stocks. Failing to do so can result in missing out on potential investment opportunities or selecting stocks with higher risks.
  3. Overlooking liquidity: Liquidity is crucial when trading stocks, as it can impact your ability to buy or sell shares at a fair price. Make sure to include liquidity criteria in your stock screening process to avoid getting stuck in illiquid positions.
  4. Neglecting to update your screener regularly: Markets are constantly changing, and what may have been a suitable stock yesterday may not be today. Make sure to update your screening criteria regularly to keep up with market trends and changes.
  5. Relying too heavily on the screener's output: While stock screeners can be helpful tools, they should not be the sole basis for making investment decisions. Always conduct further research and analysis on the stocks identified by the screener to ensure they align with your investment goals and risk tolerance.
