What is Stock Screener

Types of Research:

Pen & Paper:

The investor calculates the ratio for each stock with a pen and paper with formulas and data.

Algorithmic Trading:

Algo Trading is a type of trading where computer algorithms are used to execute trades based on pre-determined instructions.

But some traders want a bit of both. They want to be in control of the trades that they want to execute but also want a tool to simplify calculations.

This is where Screener comes in.

Screener is a tool that investors and traders use to filter stocks based on specific criteria, such as market capitalization, price-to-earnings ratio, or dividend yield.

The screener helps to narrow down thousands of companies to a small group of companies that meet the investor’s or trader’s specific requirements.

While screeners may use algorithms to filter stocks based on specific criteria, they do not execute trades automatically like algo trading.

Instead, the investor or trader must manually review and analyze the stocks that the screener has identified as meeting their criteria, and then decide whether to buy or sell the stocks.

Stock Screening

Stock screening is the process of selecting stocks based on specific criteria such as market capitalization, price-to-earnings ratio (P/E ratio), return on equity (ROE), debt-to-equity ratio, current ratio, earnings per share (EPS), and dividend yield. A stock screener is a tool that allows investors to screen stocks based on these criteria and more.

A stock screener helps investors narrow down thousands of companies to a small group of companies that meet their criteria.

Investors just need to enter their criteria based on thousands of ratios that are available on the screener.

Whatever type of stocks an investor is interested in, they can think of a query and the screener will show them the companies that fulfill their requirements.

How Does a Stock Screener Work?

A stock screener usually has three components: a database of companies, a set of variables, and a screening engine that matches the former two components to produce results.

One can go on to the screener, enter the criteria of their preference, for example, market cap>100 million. The companies that fit the criteria are displayed. One can enter more than one variable. Multiple ratios can be added by using “AND” and “OR” if the screener supports these rules.

The trader can access hundreds of ratios with the screener.

In a query-based screener, the investor can run the query after keying in the input and this will list the various companies that fit the criteria.

The investor can then analyze the various alternatives listed and choose the most feasible one.

Few screeners provide a collection of stocks under various categories that a user can directly look into.

An investor can use a stock screener to screen ETFs based on their preferences.

Price to Earnings Ratio

One of the most commonly used criteria for screening stocks is the price-to-earnings (P/E) ratio. The P/E ratio is the ratio of the company’s stock price to its earnings per share (EPS). The P/E ratio is an important metric as it indicates how much an investor is willing to pay for each rupee of earnings.

A low P/E ratio indicates that the stock is undervalued and has a higher potential for growth. A high P/E ratio indicates that the stock is overvalued and may not have much room for growth. A stock screener can be used to screen for stocks with a low P/E ratio, indicating that they are undervalued and have a higher potential for growth.
