How to Use Stock Book Value Screener for Better Investment Decisions [Tutorial]
A stock book value screener finds companies where the stock price is low relative to the accounting value of their net assets. That single filter, applied correctly, has underpinned value investing since Benjamin Graham published "Security Analysis" in 1934. The challenge is applying it correctly. Used alone, a low price-to-book ratio is as likely to flag a dying business as a bargain. This tutorial shows you exactly how to use the ValueMarkers screener to combine book value with quality checks, so you end up with a list worth researching rather than a list of value traps.
Key Takeaways
- Book value equals total assets minus total liabilities. Price-to-book divides stock price by book value per share.
- A low P/B in isolation means nothing. BRK.B trades at P/B 1.5 because of its capital structure, not because it is cheap relative to earnings power.
- Combine P/B with ROIC above 10% and positive free cash flow to separate genuine bargains from deteriorating businesses.
- The ValueMarkers screener lets you stack these filters in under 3 minutes across 73 exchanges.
- Sector context changes everything: financials structurally trade below P/B 1.5, while software companies at P/B 8 can still be undervalued on earnings.
- Always verify the book value composition: goodwill-heavy book values are less reliable than tangible book values.
What Book Value Actually Measures
Book value is the balance sheet number you get when you subtract all liabilities from all assets. Divide that by shares outstanding and you have book value per share. The price-to-book ratio divides the current stock price by that per-share number.
If a company has $10 billion in assets, $6 billion in liabilities, and 500 million shares outstanding, its book value per share is ($10B - $6B) / 500M = $8.00. If the stock trades at $12, the P/B is 1.5.
The idea behind using P/B in a stock book value screener is that buying at a discount to book provides a margin of safety. If the business fails, asset liquidation should return close to book value. That logic holds for asset-heavy companies. It breaks down for companies where the main assets are intangible: brands, software, patents, customer relationships.
Step 1: Open the Screener and Set Your Exchange
Go to the ValueMarkers screener. By default it shows all 73 exchanges. For most value investors, start with the exchanges you know and can research. Select "United States" or "United States + United Kingdom" to begin.
This narrows the universe to roughly 4,000 to 5,000 stocks with reliable data. You can always expand later once you have a working filter set.
Step 2: Set the Price-to-Book Filter
Find the "Valuation" tab in the screener. Set P/B maximum to 2.0 for a tight value screen, or 3.0 for a broader starting point.
At P/B below 2.0 with U.S. stocks, you will see approximately 900 to 1,200 results in most market conditions. That is still too many to research individually, which is why the next steps matter.
Note what you are seeing in the results already: banks and insurance companies dominate. Financials structurally carry low P/B because they operate with high leverage. This is not a flaw; it is sector behavior. Keep that in mind as you refine.
Step 3: Add the ROIC Quality Filter
Cheap on book value means nothing if the company cannot earn a return on that capital. Add ROIC above 10% under the "Quality" tab.
This single addition changes the character of the list dramatically. Capital-intensive businesses with low earnings power disappear. What stays are companies that are both cheap on assets and generating real returns. AAPL delivers ROIC of 45.1% with a P/B well above 2, so it rarely appears in a book value screen. But smaller industrials or financial holding companies with ROIC of 12-18% and P/B below 1.5 are exactly the territory a stock book value screener is designed to find.
Step 4: Add Debt-to-Equity Below 1.5
A company can show a low P/B partly because it carries so much debt that equity is depressed. That is not value; it is financial risk.
Filter for debt-to-equity below 1.5 (or, for financials, use the Tier 1 Capital filter instead). This removes the overleveraged names where book value is more fiction than fact.
Step 5: Require Positive Free Cash Flow
Add the free cash flow filter: positive FCF for at least 2 consecutive years. This removes turnaround stories and companies where assets exist on the balance sheet but cash generation is absent.
| Filter | Setting | Rationale |
|---|---|---|
| P/B | Below 2.0 | Core value signal |
| ROIC | Above 10% | Quality gate |
| Debt-to-Equity | Below 1.5 | Balance sheet health |
| Free Cash Flow | Positive, 2+ years | Cash reality check |
| Market Cap | Above $500M | Minimum liquidity |
| Piotroski F-Score | 6 or above | Multi-factor quality |
After applying all six filters, your list should be 40 to 80 stocks. That is a manageable watchlist.
Step 6: Sort by VMCI Score
The VMCI Score aggregates five pillars: Value (35%), Quality (30%), Integrity (15%), Growth (12%), and Risk (8%). After your book value filters narrow the list, sorting by VMCI Score ranks the remaining stocks by composite fundamental strength.
The top 20 names by VMCI Score from your filtered list are your primary research candidates. These are companies that are cheap on book value, earn real returns, carry reasonable debt, and generate cash.
Step 7: Check Tangible Book Value for High-Goodwill Names
Book value includes goodwill from past acquisitions. Goodwill is an intangible asset that can be written down in a bad year, instantly shrinking book value and making a stock look more expensive than it was.
For any name that passed your filters but has a large goodwill position (check the balance sheet breakdown in the screener detail view), switch to tangible book value per share. Recalculate the P/B using that number.
A company with $8 book value per share but $5 in goodwill has tangible book value of $3. If the stock trades at $10, the P/tangible B is 3.3, not 1.25 as reported. That changes the analysis significantly.
Real Example: Running the Screen in Practice
Using these filters on the U.S. market in early 2026 produces a list that includes financial holding companies, select industrials, and a handful of healthcare names. JNJ at P/B around 5 does not appear. BRK.B at P/B 1.5 does, assuming you relax the ROIC filter slightly for holding companies.
A typical output name might look like: a regional bank holding company with P/B of 0.9, ROIC of 11.4%, debt-to-equity of 0.6 (excluding deposit liabilities), and 5 consecutive years of positive FCF. That kind of profile is what the screen is built to surface.
Run the filtered list through the DCF calculator for the top 5 names. Confirm that intrinsic value estimates from discounted cash flow also support the book value signal. When both methods agree the stock is cheap, the conviction level rises.

Frequently Asked Questions
what happens if the stock market crashes
A stock market crash reduces the prices of nearly all equities, regardless of quality. For value investors using a stock book value screener, a crash is often an opportunity: it pushes P/B ratios down across the board, creating conditions where strong companies trade at rare discounts. The key is having cash available and a pre-built watchlist ready before the crash arrives, so you can act on prices rather than panic.
what time does the stock market open
U.S. stock markets open at 9:30 a.m. Eastern Time on weekdays. Pre-market trading on most platforms starts at 4:00 a.m. Eastern, but volume is thin and spreads are wide before regular hours. For value investors running a stock book value screener, the opening time is less relevant than end-of-day prices, which is when the data underlying screener filters is updated.
are stock markets closed today
U.S. stock markets are closed on federal holidays: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. When markets are closed, screener data reflects the prior trading session's closing prices. Check the NYSE or NASDAQ website for the official holiday schedule.
what time does the stock market close
U.S. stock markets close at 4:00 p.m. Eastern Time on regular trading days. After-hours trading on major platforms runs until 8:00 p.m. Eastern. For screener purposes, P/B calculations and other fundamental data update once daily after market close, using official closing prices from exchange feeds.
when does the stock market open
The New York Stock Exchange and NASDAQ open at 9:30 a.m. Eastern Time, Monday through Friday, excluding federal holidays. The London Stock Exchange opens at 8:00 a.m. GMT. Tokyo opens at 9:00 a.m. JST. The ValueMarkers screener covers all 73 exchanges with their respective market hours reflected in data timestamps.
why is the stock market down today
Markets decline for many reasons: interest rate moves, earnings misses, geopolitical events, inflation data, or broad risk-off sentiment. For value investors, the reason matters less than the magnitude and the valuation it creates. A 5% market decline can push a stock you have been watching into book value territory it has not seen in years. That is when the stock book value screener becomes most useful: filter during downturns, buy the quality names that appear.
Start filtering now with the ValueMarkers screener and apply the book value criteria from this tutorial to build your first quality watchlist.
