Overview
A deep value investing screener is a tool or methodology that helps investors identify stocks trading significantly below their intrinsic value. It uses quantitative filters based on valuation ratios, financial health, and profitability metrics to generate a list of potential deep value opportunities. This screening process allows investors to focus research efforts on stocks with the highest potential margin of safety.
Core Screening Criteria
- Valuation Metrics
- Price-to-Book (P/B) Ratio: Targets companies trading below book value.
- Example: P/B < 1
- Price-to-Earnings (P/E) Ratio: Stocks trading below historical or sector averages.
- Example: P/E < 10
- Price-to-Cash-Flow (P/CF) Ratio: Companies generating cash at discounted valuations.
- Example: P/CF < 5
- Dividend Yield: Higher than sector or historical averages, indicating undervaluation.
- Example: Dividend yield > 4%
- Price-to-Book (P/B) Ratio: Targets companies trading below book value.
- Financial Health Metrics
- Debt-to-Equity Ratio: Preferably below 1.0 to ensure manageable leverage.
- Current Ratio: Above 1.0 to indicate sufficient short-term liquidity.
- Free Cash Flow: Positive and ideally growing to sustain operations and dividends.
- Profitability Metrics
- Return on Equity (ROE) above 5%
- Net Profit Margin above 5%
- Earnings stability over the last 3–5 years
- Market Cap / Size Filter
- Small-cap and mid-cap companies often have higher mispricing potential.
- Example: Market cap < $5 billion for small-cap focus
Example Screening Table
| Metric | Screening Criteria | Purpose |
|---|---|---|
| P/B Ratio | < 1 | Identify undervalued assets |
| P/E Ratio | < 10 | Identify low-priced earnings |
| P/CF Ratio | < 5 | Identify undervalued cash-generating stocks |
| Dividend Yield | > 4% | Capture income and undervaluation |
| Debt/Equity | < 1 | Ensure financial stability |
| Market Cap | < $5B | Target small/mid-cap inefficiencies |
Screening Steps

- Apply Financial Health Filters

Rank stocks with the highest margin of safety first.
Final Review
- Analyze news, industry trends, and company-specific catalysts before selecting investments.
Example of Screener Output
| Ticker | Sector | P/E | P/B | P/CF | Dividend Yield | Debt/Equity | MOS |

| ABC | Industrials | 8 | 0.7 | 4 | 5% | 0.6 | 45% |
| XYZ | Consumer | 9 | 0.8 | 3 | 4.5% | 0.4 | 50% |
