Stock Screener

Investing in the stock market can be overwhelming for beginners, given the many publicly traded companies. However, a screener can make a world of difference. In this blog post, we’ll delve into what a stock screener is, how it operates, and why it’s an indispensable tool for investors.

What is Stock Screener?

A screener functions like a search engine, allowing investors to filter stocks based on specific criteria. This helps them narrow the extensive array of available stocks to a more manageable number. Armed with a screener, investors can effortlessly identify stocks that align with their investment goals and criteria.

What Does a Stock Screener Do?

Investors must utilize a screener and consider various criteria to search for stocks effectively. Among these criteria, market capitalization is a crucial factor that determines the overall value of a company.  

Investors can confidently screen stocks based on their market capitalization, whether they prefer small-cap stocks (companies valued at less than $2 billion) or large-cap stocks (companies valued at over $10 billion), based on their investment strategy. In addition, investors can also use the screener to filter stocks based on their industry or sector, such as technology or healthcare.

Price: If you’re an investor looking for the best stocks, using a stock screener to filter stocks based on their share price is smart. One effective filter is to focus on stocks priced at Rs. 100 or less per share.

Dividend Yield: To narrow their investment options, investors often utilize a stock screener, which allows them to filter stocks according to their dividend yield, calculated by dividing the annual dividend payment by the stock price. Investors prioritising stocks with a 2% or higher dividend yield can use this tool.

P/E Ratio: When investing, using a stock screener is crucial. This tool enables investors to efficiently sort stocks based on their price-to-earnings (P/E) ratio. To calculate the P/E ratio, divide the price per share by the earnings per share. To ensure maximum profitability, investors should prioritize stocks with a P/E ratio below 20.

Earnings Growth: If you want to make the most out of your investments, using a reliable stock screener to sort stocks based on their earnings growth accurately is essential. Research shows that focusing on stocks with a five-year earnings growth rate of at least 10% is the key to success. Don’t settle for mediocre options – make an informed decision and invest in only the finest stocks.

Debt-to-Equity Ratio: Filtering stocks using a debt-to-equity ratio with a screener can be a practical approach for investors. This ratio is calculated by dividing the total debt by shareholder equity. Therefore, it is advisable to prioritize stocks with a debt-to-equity ratio below 0.5 for more favorable investment results.

Why is a Stock Screener Useful?

A stock screener is a valuable tool for investors for several reasons.

First, it allows investors to narrow down the universe of available stocks quickly and easily. Instead of sifting through thousands of stocks, investors can use a screener to focus on a smaller subset of stocks that meet their investment criteria.

Second, a stock screener can help investors identify investment opportunities. By filtering stocks based on specific criteria, investors can identify stocks that may be undervalued or have strong growth potential.

Third, a screener can help investors avoid potential investment pitfalls. By filtering stocks based on criteria such as debt-to-equity ratio or earnings growth, investors can avoid stocks that may be too risky or have poor financials.

Finally, a stock screener can help investors save time and effort. Instead of spending hours researching individual stocks, investors can use a screener to identify stocks that meet their investment criteria quickly.

How to Use a Stock Screener?

Using a stock screener is a simple process. Numerous free online screeners are available, and most online brokers offer a screener tool. Follow these steps to get started:

1. Determine your investment criteria: Before using a stock screener, identify the criteria you will use to filter stocks. This could involve market capitalization, industry, price, dividend yield, P/E ratio, earnings growth, debt-to-equity ratio, and more.

2. Choose a stock screener tool: Select a tool that suits your needs. Some popular free online stock screeners include Finviz, Yahoo Finance, and Google Finance.

3. Input your investment criteria: Once you’ve chosen a stock screener tool, input your investment criteria into the tool. Most stock screeners provide a range of filters and criteria, enabling you to customize your search to meet your needs.

4. Review the results: After inputting your investment criteria, the stock screener tool will generate a list of stocks that meet your criteria. Review the list of results and conduct further research on the stocks that pique your interest.

5. Evaluate the stocks: Once you’ve identified a list of potential investment opportunities, it’s time to evaluate each stock to determine if it’s a good investment. Then, conduct thorough research on the company, its financials, and its industry before making final decisions. With these steps, you can confidently use a stock screener to identify investment opportunities that align with your goals.


In summary, a screener is essential for investors who want to discover investment opportunities that meet their specific requirements. It efficiently filters through stocks based on market capitalization, industry, price, dividend yield, P/E ratio, earnings growth, and debt-to-equity ratio, allowing investors to narrow their choices quickly and easily. However, investors must thoroughly research each stock before committing to their funds.
