Essential Screening Criteria

Stock screening success depends on selecting the right combination of fundamental metrics and technical indicators. These criteria help identify stocks that match specific investment strategies and risk tolerance levels.

Fundamental Metrics

Fundamental metrics evaluate a company’s financial health and market position through quantifiable data points:

  • Valuation Ratios

  • Price-to-Earnings (P/E): Measures stock price relative to earnings per share
  • Price-to-Book (P/B): Compares market value to book value
  • Price-to-Sales (P/S): Evaluates stock price against revenue per share
  • Growth Metrics

  • Revenue Growth Rate: Shows year-over-year sales increases
  • Earnings Growth Rate: Tracks profit expansion over time
  • Dividend Growth Rate: Indicates dividend payment increases
  • Financial Health Indicators

  • Debt-to-Equity Ratio: Measures financial leverage
  • Current Ratio: Assesses ability to pay short-term obligations
  • Return on Equity (ROE): Shows efficiency in generating profits

Technical Indicators

Technical indicators analyze price movements and trading patterns to identify market trends:

  • Trend Indicators

  • Moving Averages: 50-day, 200-day averages track price trends
  • MACD: Identifies momentum shifts and trend changes
  • Relative Strength Index (RSI): Measures price momentum
  • Volume Metrics

  • Trading Volume: Shows market participation levels
  • On-Balance Volume: Tracks buying vs selling pressure
  • Volume-Weighted Average Price: Combines price and volume data
  • Support Levels: Identifies price floors
  • Resistance Levels: Shows price ceilings
  • Chart Patterns: Flags, triangles, head and shoulders formations

Each indicator provides specific insights into market conditions and stock behavior. Combining multiple indicators creates a comprehensive screening strategy for identifying potential investments.

How to Create Custom Stock Screens

Creating custom stock screens empowers you to find investment opportunities that match your specific criteria and investment strategy. Here’s a systematic approach to building effective screens.

Setting Parameters

Stock screening starts with defining clear parameters that align with your investment goals. Set specific values for fundamental metrics like P/E ratios, market capitalization, dividend yield or earnings growth. Add technical indicators such as moving averages, RSI or volume thresholds to refine your search. Common parameter combinations include:

  • Growth metrics
  • Revenue growth rate > 10%
  • Earnings per share growth > 15%
  • Operating margin > 20%
  • Value indicators
  • P/E ratio < market average
  • Price-to-book ratio < 3
  • Debt-to-equity ratio < 1.5
  • Technical filters
  • 50-day moving average above 200-day
  • Relative Strength Index between 30-70
  • Daily trading volume > 100,000 shares

Filtering Results

The filtering process transforms raw data into actionable insights through these steps:

  1. Apply primary filters
  • Set market cap requirements
  • Choose specific sectors or industries
  • Define price range limitations
  1. Add secondary criteria
  • Include profitability metrics
  • Set minimum dividend requirements
  • Specify analyst ratings thresholds
  1. Fine-tune results
  • Sort by performance metrics
  • Remove outliers
  • Cross-reference with other indicators

Remember to adjust your filters based on market conditions and maintain flexibility in your screening criteria. Testing different parameter combinations helps optimize your screening strategy for better results.

Common Stock Screening Mistakes to Avoid

Relying on Single Metrics
Focusing on a single metric like P/E ratio or price momentum limits your screening effectiveness. Combine 3-4 complementary metrics, such as P/E ratio, debt-to-equity ratio, and earnings growth rate, to create a balanced screening approach.

Setting Unrealistic Parameters
Overly strict screening criteria eliminate too many potential opportunities. For example, setting a P/E ratio below 10 with 25% annual revenue growth excludes many quality stocks. Adjust your parameters to match current market conditions and industry standards.

Ignoring Market Context
Stock screening parameters perform differently across various market cycles. What works in a bull market might not work in a bear market. Modify your screening criteria based on:

  • Current economic conditions
  • Interest rate environment
  • Sector-specific trends
  • Overall market sentiment

Overlooking Data Quality
Stock screening results are only as reliable as their data sources. Common data issues include:

  • Outdated financial information
  • Incorrect calculations
  • Missing values
  • Inconsistent reporting periods

Neglecting Position Sizing
Stock screens identify potential opportunities but don’t indicate how much to invest. Consider these factors for position sizing:

  • Portfolio diversification requirements
  • Risk tolerance levels
  • Stock correlation with existing holdings
  • Available capital allocation

Skipping Technical Validation
Many investors jump straight from screening results to buying decisions. Take these additional steps:

  • Review price charts for entry points
  • Check trading volume for liquidity
  • Analyze recent price patterns
  • Verify market trends in the stock’s sector
  • Entry and exit rules
  • Historical performance metrics
  • Risk-adjusted returns
  • Maximum drawdowns

Tips for Maximizing Screening Results

Set Clear Investment Goals

Define specific investment objectives before configuring screening parameters. Focus on metrics that align with your strategy, such as value investing (P/E ratio, P/B ratio) or growth investing (EPS growth, revenue growth). Establish target ranges for each metric based on historical market data.

Create Multi-Layer Filters

Build screening criteria in stages to refine your results:

  • Primary filters: Market cap, trading volume, exchange listing
  • Secondary filters: Financial ratios, growth rates, profitability
  • Final filters: Technical indicators, price momentum, analyst ratings

Balance Quantitative and Qualitative Factors

Look beyond pure numbers when evaluating screening results:

  • Compare industry averages for context
  • Check recent company news for material events
  • Review competitive position in the sector
  • Examine management track record
  • Analyze market trends affecting the business

Implement Regular Review Cycles

Schedule periodic reviews of your screening strategy:

  • Weekly updates for technical indicators
  • Monthly checks of fundamental metrics
  • Quarterly reassessment of screening parameters
  • Annual evaluation of overall strategy effectiveness

Document Your Process

Track your screening decisions systematically:

  • Record parameter changes with dates
  • Note successful filter combinations
  • Log unsuccessful screening criteria
  • Keep a database of promising candidates
  • Monitor performance of screened stocks
  • Test one parameter change at a time
  • Monitor results for 3-4 weeks
  • Compare outcomes across market conditions
  • Document performance improvements
  • Remove ineffective filters promptly
