The process begins with objective valuation measures such as price-to-earnings and price-to-book ratios, then combines them with upward price momentum. These factors are treated as complementary: value seeks an inexpensive entry point, while momentum helps avoid assuming every falling stock is a bargain. Quality overlays then remove companies whose weak balance sheets or poor profitability make their apparent cheapness hazardous. The resulting list is not a set of automatic purchases. It is a manageable research queue, and the same measures can be applied in minutes whenever a promoted or newsworthy stock appears. The output is a consistent pursue-or-walk-away decision that reduces dependence on stories, excitement, and subjective impressions.

Core principles
- 01Quantitative rules reduce narrative-driven decisions
- 02Value and momentum contribute different information
- 03Cheap stocks still require quality filters
- 04A screen identifies research candidates rather than automatic purchases
- 05The process should be simple enough to apply consistently
How to run it
- 1
Set the Value Rules
Choose objective valuation measures and thresholds before screening. Rotblut discusses low price-to-book and price-to-earnings as practical starting points.
Pro tip Test both absolute thresholds and relative comparisons with historical or peer valuations.
Watch out A low multiple alone may indicate deterioration rather than opportunity.
- 2
Require Upward Momentum
Check that the stock's price trend is moving upward according to a consistently defined momentum rule. This adds information independent from the valuation signal.
Pro tip Use one repeatable measurement period across every candidate.
Watch out Do not redefine momentum to rescue a favorite stock.
- 3
Remove Weak Balance Sheets
Exclude companies with financial structures that create an unacceptable risk of distress. Review debt, liquidity, and the ability to meet obligations.
Pro tip Compare leverage with appropriate industry peers.
Watch out Highly leveraged companies can look statistically cheap immediately before serious trouble.
- 4
Filter for Profitability
Remove businesses whose poor or unstable profitability undermines the valuation case. Favor companies with evidence that operations can support shareholder value.
Pro tip Look for consistency and cash generation, not just one unusually strong period.
Watch out Accounting earnings without supporting cash flow deserve closer scrutiny.
- 5
Rank the Survivors
Sort qualifying stocks by the combined strength of value, momentum, and quality. Use the ranking to focus limited research time.
Pro tip Keep the ranking formula simple enough to explain and reproduce.
Watch out A high rank is an invitation to investigate, not a command to buy.
- 6
Make the Pursue-or-Walk-Away Decision
Apply deeper company analysis to the highest-ranked candidates, including business risks and valuation assumptions. Reject ideas that fail the review even if their screen scores are attractive.
Pro tip Use the same quick screen when a stock is promoted in the news.
Watch out Do not let an exciting narrative override failed quantitative criteria.
In the wild
A television guest praises a little-known company. Instead of buying immediately, an investor checks its valuation, price momentum, balance sheet, and profitability. The stock is inexpensive and rising, but excessive debt causes it to fail the quality overlay.
→ The investor walks away after a five-minute first-pass analysis and avoids a narrative-driven purchase.
A broad-market screen identifies a profitable small company with a low valuation, upward price movement, manageable debt, and positive cash generation. The investor then studies filings and competitors before opening a diversified position.
→ A repeatable screen surfaces a candidate outside the heavily covered large-cap universe.
Common mistakes
Buying Cheapness Without Momentum
A falling, low-multiple stock may be a value trap. The momentum condition supplies a separate indication that market expectations may be improving.
Skipping the Quality Overlay
Weak balance sheets and poor profitability can overwhelm attractive valuation metrics. Quality filters are essential for removing the junkier candidates.
Treating the Screen as Due Diligence
A quantitative screen narrows the universe but does not explain the business, risks, or durability of earnings. Survivors still require deeper research.
Is it for you?
Best for
It is best for individual investors who need a repeatable first-pass screen for a broad stock universe.
Not ideal for
It is not ideal for investors unwilling to research individual companies or tolerate company-specific risk.

“if you just get value momentum, those two factors which are completely uncorrelated, low value and upward moving price. That alone is the cornerstone you…”
“And then just overlay some of factors to get rid of the junkier stocks, the stocks with bad balance sheets, the stocks are less profitable…”
