🧠 What Is a Stock Screener?
A stock screener is a tool that filters stocks based on specific criteria — like P/E ratio, dividend yield, market cap, or growth rate. It helps investors narrow down thousands of public companies to a shortlist that meets their investing goals.
Whether you're looking for:
📉 Deep value plays
📈 Growth-at-a-reasonable-price (GARP) picks
💵 Dividend bargains
...a screener can do the heavy lifting.

📊 Key Metrics to Find Undervalued Stocks
Before jumping into tools, let’s look at fundamental filters every value investor should understand:
Metric What It Tells You
P/E Ratio Price vs earnings; lower may indicate undervaluation
P/B Ratio Price vs book value; <1 can signal a discount
PEG Ratio P/E adjusted for growth; <1 = value
Debt-to-Equity Shows financial health and risk
Free Cash Flow Cash available after expenses; positive = strong
Dividend Yield Higher yield may indicate value but watch for risk
Set these filters based on your goals to target the right opportunities.

🔧 Pro Tips for Screening Undervalued Stocks in 2025
✅ Customize filters: Don’t rely on default settings — adjust P/E, market cap, and debt filters to suit your strategy.
🚩 Watch value traps: A low P/E or P/B alone doesn’t mean it’s a good stock — check debt levels, margins, and industry health.
🧠 Use multiple screeners: Cross-reference picks from Finviz and Morningstar or GuruFocus for a multi-angle analysis.
📈 Re-screen regularly: Markets change fast — set weekly or monthly checks to catch new entries.
