Let’s dive into the world of stock screeners and how investors can benefit from them to navigate through challenging financial markets. 

Data Stock Screeners Typically Offer

Stock screeners provide investors with a range of fundamental and technical research tools to aid in stock evaluation. Below are the types of analysis that are usually accessible with stock screeners. 

Fundamental Analysis:

Price-to-Earnings Ratio (P/E): This ratio, which is frequently used to evaluate valuation, contrasts the current stock price of a business with its earnings per share (EPS).

Earnings Per Share (EPS): This metric, which is derived by dividing net income by the total number of outstanding shares, shows how profitable a company is.

Price-to-Book Ratio (P/B): This ratio assesses how much an asset is worth by comparing its market value to its book value.

Dividend Yield: This metric expresses the return from dividends by calculating the annual dividend income as a proportion of the stock’s current price.

Debt-to-Equity Ratio: This ratio evaluates the amount of debt compared to equity held by a business, indicating its level of leverage and stability.

Return on Equity (ROE): Return on Equity is a crucial metric for assessing management effectiveness since it shows how profitable a business is in relation to the equity held by its shareholders.

Revenue Growth: Screeners may offer filters for revenue growth rates across various periods to evaluate a company’s sales success.

Technical Analysis:

Moving Averages: To spot patterns and possible buy/sell signals, users can filter stocks using moving average indicators, such as the exponential moving average (EMA) or simple moving average (SMA).

Relative Strength Index (RSI): This indicator helps spot possible reversals by assessing the size of recent price movements to determine if an asset is overbought or oversold.

The Moving Average Convergence Divergence, or MACD, is a momentum indicator that follows trends and can be used to spot shifts in a trend’s intensity, direction, momentum, and length.

Bollinger Bands: These bands reveal information about price volatility and possible breakout spots. They are made up of a simple moving average and two standard deviations above and below the average.

Volume Analysis: To find companies with unusual trading activity, which may indicate future price moves, screeners may incorporate filters for volume indicators.

Support and Resistance Levels: Using historical price data, some screeners provide tools to identify support and resistance levels, assisting investors in determining when to enter and quit the market.
