What is a Stock Screener

Mar 30, 2023 By Kelly Walker

Joseph Hogue, CFA, a former writer at My Stock Market Fundamentals and venture capital analyst, explains that stock screeners are excellent for reducing your list of probable stocks to invest in. Since there are over 3,000 equities traded on the New York State Exchange alone, excluding those that might not be excellent investments works to narrow the list.

Several stock screeners offer a free option for their most basic functions and a premium option for their more advanced features. Independent websites are home to some of the most well-known stock screeners, but some brokerage firms also offer this service.

How to get started with Stock Screeners?

Finding quality stocks takes a lot of work. Sorting through masses of data is required while creating a stock portfolio. In the U.S. markets alone, there are hundreds of publicly traded enterprises to compare and innumerable options available globally.

Finding the best stock is challenging because of the sheer volume of enterprises, and the amount of online information only helps a little. It can be challenging to separate valuable information from useless data. Nevertheless, a stock screener may guide your emphasis on the stocks that satisfy your criteria and complement your approach.

Stock screeners are useful filters when you know the types of enterprises you want to invest in. It isn't practical to track all of the millions of stocks traded on exchanges in the U. S. on your own. Stock screeners restrict exposure to just the stocks that fit your specific criteria.

How to use Stock Screeners for Day Trading

Stock screeners are typically used for day trading. These tools help day traders to determine which stocks, out of the thousands offered on international exchanges, need their attention. The stock screeners tools can help in your decision-making regarding the stocks in which you should invest your money.

Moreover, stock screening involves looking for companies that satisfy specific financial requirements.

There are three components of a stock screener:

  • A listing of companies
  • Several factors
  • A screening tool identifies the companies that meet those criteria and produces a list of matches.

A stock screener is simple to use. You must first respond to a list of questions. They might consist of the following:

  • Do you prefer small- or large-cap stocks?
  • Are you trying to find enterprises with stocks that have dropped in price or stock markets at all-time highs?
  • What price-to-earnings ratio (P/E) range do you consider to be acceptable?
  • Are you trying to find stocks in a specific sector?

You can search by using any statistic or parameter you want with the help of good screeners. Once your answers have been entered, you will be given a list of companies that fit your criteria.

Stock screeners facilitate their customers in performing quantitative analysis by concentrating on the quantifiable aspects influencing a stock's price. On the other hand, stock screening prioritizes measurable factors, including revenue, market capitalization, profit margins, volatility, and performance ratios like the debt-to-equity ratio (D/E) or P/E ratio. You must use something other than a stock screener to look for a company that produces the best products for obvious reasons.

Best Free Stock Screeners

StockFetcher, Yahoo! Finance, ChartMill, Zacks, Finviz, and Stock Rover provide some of the best free stock screeners on the internet. They all provide users with a variety of advanced and basic screeners.

Numerous stock screeners provide free, paid, basic, and premium offerings.

The fundamental screeners use a fixed set of variables you specify as your criterion, with values. You can choose to identify businesses that fall within or outside of a specific market capitalization range by using one of the parameters on the basic Finviz screener, for instance, which filters stocks by market cap.

While a few best free stock screeners are available, you will probably need to subscribe to a stock screening service if you want the most up-to-date and cutting-edge technology.

The websites listed below provide some of the best-predefined screens:

Finviz: This stock screener has a signal drop-down box that allows users to select filters for recent insider purchases, top gainers, and wedges, among other criteria.

Yahoo! Finance: This website has several preset displays. Day Gainers, Portfolio Anchors, and Undervalued Big Caps are a few of the most prominent. You can understand the guiding principles of each predefined screen by understanding the search parameters of that screen.

Limitations of Stock Screeners

Stock screeners also have some limitations, even though they are useful tools. You should consider the following limitations:

  • The majority of stock screeners simply consider statistical parameters. There are still a lot of qualitative considerations.
  • Screeners use datasets that update on various schedules, but they don't provide information on ongoing legal disputes, labor issues, or levels of customer satisfaction.
  • Always verify the data's accuracy and relevancy. Your search can be fruitless if a screener's database is not up to date.
  • Be on the lookout for sector-specific blind spots. For instance, don't expect a lot of technology companies to come up if you search for low P/E ratios.

Bottom Line

Thanks to stock screeners, you can easily select thousands of stocks based on your precise criteria. It's crucial to take some time to establish your investment objectives and approach before attempting to choose the ideal stock screener. You can more accurately determine the characteristics required for a screener if you have a strong foundation in those two areas.
