Stock Screener: Definition

If you are still wondering what a stock screener is in the stock market, let's start by defining it. The investor's instrument for rapidly and simply locating investment possibilities is the stock screener. Investors may now use important financial parameters, such as market cap, using a stock screener to identify excellent investment possibilities.


Sorting through masses of data is required while creating a stock portfolio. On stock exchanges alone, there are hundreds of publicly listed firms to compare, not to mention the innumerable alternatives accessible globally. A day trader could choose shares with large volume and regular price changes, whereas a value investor might prefer businesses with quickly increasing revenues. A decent screener will provide you with a list of stocks that fit your desired parameters. Our dividend calculator for stocks is a free and easy-to-use tool that can help you invest wisely.

Advantages of Stock Screeners

Let's delve into the advantages of stock screeners in detail.

  • Stock Screeners Save Time

    The stock market has hundreds of stocks, yet stock screening databases often only cover a portion of them. The data collection may contain dozens to thousands of equities based on the database, and it would be hard for most investors to properly analyze every single one of them. It would take much too long to examine each company's financial statements, ratios, multiples, and potential for future development.

  • Stock screeners prevent behavioral biases

    The screener eliminates stocks that don't fulfil your criteria and generates a list of stocks that do once you decide which metrics will be included in your stock screen. Less stock will cross the screen when the screening parameters are tightened. For instance, you can look for companies with a price-to-earnings (P/E) ratio below a particular threshold if you're looking for inexpensive securities. If growth is more important to you than value, you may search for firms with strong year-over-year profit growth.

    Investors are susceptible to irrational inclinations that might influence their decision-making. These are typically regarded as "behavioral biases," and they can be challenging to identify and prevent. These biases may cause investors to make incorrect financial choices that, over time, reduce profits. For instance, investors frequently alter their strategies to accommodate particular equities. Traders may persuade themselves to buy the stock even if, in accordance with my investing plan, it had a price-to-earnings (P/E) ratio that was too high or had too little revenue growth. By removing these kinds of biases, stock screening aids investors in maintaining objectivity.

    However, a stock screener won't completely shield you from behavioral biases. For instance, I could adjust trader screening criteria until Target passed if the trader wanted it to pass.

  • Stock screeners identify fresh investing possibilities

    The ability to uncover possible purchases that trade would not have thought about otherwise is yet another significant advantage of stock screening. If a screening database has 6,300 stocks, it probably contains some stocks that you've never heard of. The less well-known stocks are sometimes neglected and, thus, undervalued on the market. A knowledgeable investor employing a stock screening tool has a chance with this problem.

How stock screeners work?

A stock screener is linked to a directory of stocks (such as all the stocks listed on the Bombay Stock Exchange). The tool scans a database, screens and sorts the stocks based on the user's preferences, and then presents the results. The database that the tool reads is obtained from stock exchanges or representatives that have the right to sell the data. Data includes the balance sheet, profit and loss, cash flow, quarterly and half-yearly outcomes, asset value ratio, stock ownership pattern, market performance, operating income, listing information, company profile, history of corporate action, etc.

Stock screeners are made up of three parts:

  • Database of companies, collection of variables.

  • An engine that compiles a list of firms by filtering the stocks according to the variable.

  • Stock screener Candlestick, for example, uses a strong pattern and a precise set of rules to identify trade settings.

These screeners examine the responses given by the investors.

Among the inquiries are:

  • Do stocks have a large or small-cap?

  • Stocks that are soaring, or those that have seen a decline?

  • range of equities' price-to-earnings ratios?

  • Industry-specific stocks

You will be presented with a list of these firm shares that meet your investment techniques as soon as you indicate your interest. Find screeners that allow you to enter practically any measure you choose.


Consider that you are a shareholder looking for stocks that pay dividends. A firm must pay dividends to its shareholders. Start by choosing the country in a stock screener, such as india. The index portion is next; an index evaluates the performance of a collection of distinct equities. We'll use the Nifty 50, which represents the 50 largest stocks, for this example. If you're keeping up, you'll notice that these two options have already limited the list of businesses to big Indian firms when you press the blue search button. But we can further reduce our list by using other variables.


Thousands of stocks may be easily curated based on your precise criteria thanks to stock screeners. It's crucial to take some time to establish your investment objectives and approach before attempting to select the ideal stock screener. You can more accurately determine the characteristics you would require for a screener if you have a strong foundation in those two areas. But even if you reduce the options down to only a few items, don't just blindly buy in them because they satisfy a few conditions, warns the author. Always devote a bit extra time to the stock's investigation to ensure the business is a wise investment.
