How Do You Get Started with Stock Trackers?


Choosing good stock is not easy. The sheer size of companies makes it harder to focus on a good stock, and the volumes of data on the internet don't make things any easier. In fact, it is difficult to separate the useful information from all worthless data. Fortunately, a stock scanner can help you focus on stocks that meet your standards and fit your strategy. Stock scanners are effective filters when you have a specific idea about the types of companies you want to invest in. There are thousands of stocks listed on stock exchanges in the United States alone; It is not possible to follow them all alone. A stock scanner limits exposure to only stocks that meet your unique parameters.




  • Stock scanning involves searching for companies that meet certain financial criteria.
  • By answering a series of questions and entering your search criteria, the crawlers give you a list of stocks that meet your needs.
  • Yahoo! Finance, StockFetcher, ChartMill, Zacks, Stock Rover, and Finviz offer some of the best free screens on the web.
  • Make sure you get the qualifying results as a first step and don't forget to do your own research as well.


How do Stock Trackers work?


Day traders often use stock scanners to help them choose which stocks deserve attention from among the thousands of stocks available on global stock markets. You can use the same tools to help you make better decisions about the stocks you invest your money in.


  • Stock scanning is the process of searching for companies that meet certain financial criteria. A stock elimination tool has three components:
  • A database of companies
  • a set of variables
  • A scan engine that finds companies that meet these variables and generates a match list


Using a sieve is pretty easy. First, you answer a series of questions. They may include:


  • Do you like a big cap or small-cap stocks?
  • Are you looking for stock prices at all-time highs or companies with falling shares?
  • What range for price-to-earnings ratio (P/E) is acceptable to you?
  • Looking for stocks in a particular industry?


Good screeners allow you to search using pretty much any metric or criteria you want. When you're done entering your answers, you'll get a list of stocks that meet your requirements. Focusing on measurable factors that affect stock prices, stock scanners help their users to do quantitative analysis. In other words, the scan focuses on tangible variables such as market cap, revenue, volatility, and profit margins, as well as performance ratios such as the P/E ratio or debt-to-equity ratio (L/E). For obvious reasons, you can't use a screening tool to search for a company that makes the best products.


Screener Options


Some of the best free screens on the web, Yahoo! Finance, StockFetcher, ChartMill, Zacks, Stock Rover, and Finviz. All of them offer users a range of basic and advanced screeners. Many stock browsers offer both basic and advanced or free and premium services.


Basic screeners have a predefined set of variables with values you set as your criteria. For example, one of the variants in the Finviz basic browser filters stocks by market cap, giving you the option to find companies that fall below or exceed a certain market cap. Although there are some good free scanners on the market, if you want the latest and greatest technology, you will most likely need to subscribe to a scanning service.


Knowing What to Screen For


The biggest challenge of using screeners is knowing what criteria to use for your search. Hundreds of variables make the different combination possibilities almost endless. Screeners are extremely flexible, but they can't do much for you if you don't know what you're looking for or why. To assist traders, some sites have predefined stock screens with variables pre-entered.


The following sites offer some of the better-predefined screens (these are just a few of the ones out there):

  • Yahoo! Finance: This site includes several preset screens. The most notable include Undervalued Caps, Day Winners, and Portfolio Links. The search criteria for each predefined screen are clearly explained so you can understand the underlying principles of the screens. one
  • MSN Money: This includes a number of popular screens that can be further filtered and sorted by category. 
  • Finviz: This splitter includes a drop-down signal menu that filters for criteria such as top winners, latest insider buys, and wedges. 



Beware of These Limitations


Although they are useful tools, stock browsers have some limitations. Here are some things to keep in mind:

Most stock scanners only include quantitative factors. There are still many qualitative factors to keep in mind. No scanning tool provides information on issues such as pending lawsuits, worker issues, or customer satisfaction levels.


Viewers use databases that are updated in different programs. Always check the relevance and timeliness of the data. If a browser's data is not timely, your search may be pointless.

Pay attention to industry-specific blind spots. For example, if you're looking for low P/K values, don't expect too many tech companies to show up.


There are a few other general things to watch out for with these browsers. Some of the free versions come with ads, unlike many other sites. They have to make money somehow, right? This can be a bit of a hassle, especially when trying to boost your investment excitement. But if you're willing to pay a few bucks, most come with premium options that can cut through the ads. Most paid subscriptions come with better benefits like charts, real-time offers, and email alerts.


Do your research


While there are great tools like stock scans to make your life as easy as possible, you need to remember one thing: Nothing is better than doing your own research. Like any investment advice you receive, take this with a grain of salt, as a stock scanner gives you a list of stocks that match your search criteria. As noted, these viewers will not necessarily know the news that affects certain companies. So, use the stock scan results as a simple starting point and work from there. Be sure to read some of the topics that affect the companies listed in the qualifying results, such as legal or economic news - anything that could negatively impact the company's profitability. You can use this information along with the qualifying results to make better, more informed decisions about your investments. Being able to use tools with current research will make you a better trader.
