Price relative to earnings — how many dollars you pay for each dollar the company earns. High isn’t automatically bad, but it raises the bar for what has to go right.
Free undervalued stocks screener
Is this stock cheap — or just a value trap?
Market Lens ranks large U.S. companies on classic value measures — P/E, P/B, PEG, dividend yield, and more — and sets each one against a Buffett-style quality score and margin of safety, so cheap-and-strong is easy to tell from cheap-and-broken. Free, no sign-up. It’s research, not a recommendation to buy.
Four value yardsticks, in one place.
No single number tells you whether a stock is cheap. Market Lens shows the classic value-investing measures side by side, so you see the full picture instead of one convenient metric.
Price relative to book value — useful for asset-heavy businesses where what the company owns is a meaningful anchor for value.
P/E divided by growth, plus analyst price-target upside, discount from the 52-week high, dividend yield, profit margin, and debt-to-equity. Together they make up the value score that ranks the list.
Each result also carries the Buffett-style margin of safety: price versus an intrinsic estimate that averages the Graham Number (a price ceiling, skipped for Technology, Communication Services, Healthcare, and Consumer Cyclical) with a growth-adjusted fair-P/E value.
Cheap plus strong — not cheap alone.
A low price on a failing business isn’t a bargain, it’s a warning. That’s why the screener pairs its value read with a Buffett-style quality score across circle of competence, moat (margins, return on equity, revenue growth, company size), financial strength (debt, current ratio, cash flow), and margin of safety. The combination is what separates a genuine discount from a value trap — the core of the margin-of-safetyidea.
How to use it
- 01
Enter a ticker and see its value yardsticks and estimated fair value against today’s price.
- 02
Check the quality score alongside the discount. A wide margin of safety on a strong business is worth researching; the same discount on a fragile one usually isn’t.
- 03
Do your own homework. The screen is a shortlist-builder and an estimate, not a buy signal. It doesn’t predict prices or tell you what to trade.

Frequently asked questions
What does "undervalued" mean here?+
It means a stock scores well on value measures — low P/E, P/B, and PEG, a healthy dividend, a discount from its 52-week high — and, separately, how its price compares to an intrinsic estimate built from the Graham Number and a fair-P/E value. "Undervalued" is an estimate under a set of assumptions, never a guarantee.
How does the screener decide a stock might be cheap?+
It scores a curated list of large U.S. companies on P/E, P/B, PEG, analyst upside, 52-week discount, dividend yield, profit margin, and debt-to-equity, keeps the ones above a cutoff, and shows each one’s Buffett-style quality score beside it. A low price on a weak business is a value trap, not a bargain — pairing the two is what keeps the screen honest.
Does it tell me the best undervalued stock to buy?+
No. The screener helps you analyze whether a stock looks cheap and why. It never names a "best stock to buy." It scores stocks against a rules-based checklist and labels them Meets criteria, Watch, or Fails criteria. It does not tell anyone to buy or sell, it does not predict prices, and it is not investment advice. Every result is a starting point for your own research.
Why is the Graham Number sometimes missing?+
The Graham Number only works for asset-heavy, defensive companies. Market Lens deliberately excludes it for Technology, Communication Services, Healthcare, and Consumer Cyclical stocks, so a growth business isn’t judged by a formula that doesn’t fit it.
Is the value screener free?+
Yes — the full value analysis and margin-of-safety read are free, with no account required.
