How to Find Undervalued Stocks Using a Screener Fast

June 20, 2026 · 13 min read

If you're an investor or trader who wants a repeatable process for surfacing cheap, high-quality companies, this guide will show you exactly how to find undervalued stocks using a screener — specifically Finviz — without falling into classic value traps. We'll cover the metrics that matter, the filter combinations professionals actually use, and the post-screen checks that separate real bargains from broken businesses.

Stock screeners exist because the U.S. market alone lists thousands of tickers. Manually reviewing them is impossible. A well-built screen takes that universe down to a workable shortlist in seconds, letting you focus your research time where it actually pays off.

What "Undervalued" Actually Means in a Screener

Before learning how to find undervalued stocks using a screener, you need a precise definition of "undervalued." In screener language, undervaluation is always relative — relative to earnings, book value, cash flow, growth, or industry peers. There is no single absolute number that means "cheap."

The four most widely used valuation lenses are:

• Price-to-Earnings (P/E): What you pay for each dollar of annual profit. A P/E of 12 means the company would take 12 years of current earnings to pay you back.
• Price-to-Book (P/B): Market price divided by net asset value per share. Useful for asset-heavy industries like banks, insurers, and industrials.
• PEG Ratio: P/E divided by expected earnings growth rate. A PEG below 1.0 suggests you're getting growth at a discount.
• EV/EBITDA: Enterprise value over operating cash earnings — better than P/E for comparing companies with different debt loads.

The Finviz screener exposes all four directly as filter dropdowns, which is why it's such a fast tool for value hunting.

Step-by-Step: How to Find Undervalued Stocks Using a Screener

Here's the exact workflow experienced Finviz users follow to build a value screen from scratch. This is the practical core of how to find undervalued stocks using a screener in under 10 minutes.

Step 1: Define Your Investable Universe

Open the Finviz Screener and start on the Descriptive tab. Set:

• Country: USA (or your home market) — for consistent accounting standards
• Average Volume: Over 500K — eliminates illiquid microcaps that can dominate cheap lists
• Market Cap: +Mid (over $2B) for safer ideas, or +Small (over $300M) if you accept more risk

This single step removes thousands of low-quality, hard-to-trade names that would otherwise pollute your results.

Step 2: Apply Core Valuation Filters

Switch to the Fundamental tab and add:

• P/E: Under 20 (broad value) or Under 15 (stricter)
• Forward P/E: Under 15 — uses next-year analyst estimates instead of trailing earnings
• P/B: Under 3
• PEG: Under 1.5

If you want income alongside value, add Dividend Yield > 2%. At this point you've usually got a few hundred results — still too many.

Step 3: Layer in Quality Filters to Kill Value Traps

This is the step amateurs skip and pros never do. Cheap businesses are often cheap for excellent reasons. Add:

• Return on Equity: Over 10% — proves the business actually generates returns on shareholder capital
• Net Profit Margin: Over 5% — confirms genuine profitability, not accounting tricks
• EPS Growth (next 5 years): Positive or over 5%
• Sales Growth (5 years): Positive
• Debt/Equity: Under 0.5 — keeps the balance sheet conservative

Step 4: Add Technical Sanity Checks

On the Technical tab, add filters that prevent you from catching falling knives:

• RSI(14): Over 40 — avoids stocks in severe downtrends
• 200-Day SMA: Price above SMA200 (optional, for confirmed uptrends) or below (for deeper contrarian plays)

Step 5: Sort, Save, and Export

Sort the resulting list by Forward P/E or PEG ascending. You should now have roughly 10–20 candidates. Save the screen URL (Finviz lets you bookmark filter combinations) and export the list to CSV for deeper analysis.

The Three Filter Buckets Every Value Screen Needs

When you understand the logic behind the workflow, you can adapt how to find undervalued stocks using a screener to any market regime. Every robust screen blends three filter buckets:

Bucket 1: Valuation ("Is it cheap?")

P/E, P/B, P/S, PEG, EV/EBITDA, Price/Free Cash Flow. These tell you what you're paying. Use at least two — never rely on a single ratio because each can be distorted (P/E by one-off items, P/B by intangible-heavy businesses, etc.).

Bucket 2: Quality ("Is it a good business?")

ROE, ROA, ROIC, net margin, gross margin, debt/equity, current ratio. These tell you whether management is actually creating value. A 5% P/E on a company burning cash and drowning in debt is not a bargain — it's a warning.

Bucket 3: Trend & Risk ("Is the market about to wake up?")

RSI, distance from 52-week high/low, relative volume, short float. These tell you about timing and sentiment. A statistically cheap stock in a relentless downtrend may stay cheap — or get cheaper — for years.

"A screener's job is to compress 10,000 tickers into 20 ideas. Your job is to compress those 20 into the three you actually understand well enough to own."

Comparing Valuation Metrics: When to Use Which

Avoiding the Value Trap: What Screens Won't Tell You

A value trap is a stock that looks statistically cheap but keeps getting cheaper because the underlying business is deteriorating. Screeners can't see qualitative deterioration. Here's what to check manually after your screen:

• Industry decline: Is the entire sector in secular decline? (Print media, traditional retail, certain energy sub-sectors.)
• Earnings quality: Are reported earnings backed by cash flow, or are they accounting constructs?
• Customer concentration: Does one client represent 30%+ of revenue?
• Regulatory overhang: Pending lawsuits, antitrust action, policy changes?
• Management track record: Capital allocation history, insider buying or selling?

From Screen Output to Watchlist: The Research Workflow

Knowing how to find undervalued stocks using a screener is only half the job. Here's how to convert raw screen output into an actionable watchlist:

1. Visit each ticker's Finviz profile page — it aggregates financials, news, insider transactions, and analyst ratings on a single screen.
2. Read the most recent 10-K and last two 10-Qs on the SEC's EDGAR site. Focus on the MD&A and risk factors.
3. Build a one-page thesis: Why is the market mispricing this? What catalyst will close the gap? What's your exit if you're wrong?
4. Estimate intrinsic value using at least two methods (DCF, multiples comparison, asset-based).
5. Define your margin of safety — typically 25–40% below your intrinsic value estimate.
6. Track on a watchlist and wait. Sometimes the best action is to wait for an even better entry price.

You can browse company-level data on Finviz's quote pages for any ticker that passes your screen, or scan broader sentiment using the Finviz market map to see which sectors are getting beaten down.

Common Mistakes When Using a Stock Screener

After thousands of hours of screener time, these are the patterns that ruin results:

• Over-filtering: Stacking 15 criteria so tightly you end up with zero results, then loosening randomly until you get some. Use no more than 6–8 meaningful filters.
• Single-metric reliance: Screening only on P/E. Always pair valuation with quality.
• Ignoring sector context: A P/E of 8 is cheap for a software company, normal for an oil refiner. Compare within industries when possible.
• Forgetting one-time items: Big asset sales or write-downs distort trailing earnings. Always check the income statement.
• Treating output as a buy list: Screeners produce ideas, not decisions.
• Never refreshing the screen: Market conditions change. Re-run weekly or monthly.

Conclusion: Screeners Are Telescopes, Not Verdicts

Knowing how to find undervalued stocks using a screener is one of the highest-leverage skills an individual investor can develop. A well-designed Finviz screen takes thousands of tickers down to a focused shortlist in minutes, freeing your time for the work that actually drives returns — reading filings, building valuation models, and developing investment theses.

The framework is simple: define your universe, layer valuation filters, add quality and risk checks, then sort and shortlist. The discipline is harder: never treating screen output as a buy signal, always validating with fundamental research, and accepting that some statistically cheap stocks are cheap for good reason.
