How Buffett Radar Works

Buffett Radar applies historical value investing formulas to scan the S&P 500 universe daily. We provide quantitative data snapshots that identify businesses trading at a discount to their intrinsic value based on formulaic projections.

The Six Criteria

Each ticker is evaluated across six dimensions that capture the core of Buffett's historical valuation philosophy:

Criterion 1

Company Age

What we measure: Track record and business stability

Identifying veteran businesses with proven survival over multiple economic cycles.

Criterion 2

Profit Margin Consistency

What we measure: Revenue growth and sustained profitability

Consistent margins signify potential pricing power and competitive advantages.

Criterion 3

Debt-to-Equity Ratio

What we measure: Financial leverage and balance sheet strength

Conservative debt levels signal management discipline and lower financial risk.

Criterion 4

Return on Equity (ROE)

What we measure: Capital efficiency and earnings power

High ROE suggests the company generates strong returns on shareholder capital without excessive leverage.

Criterion 5

Valuation Snapshot (P/E Ratio)

What we measure: Price relative to earnings and historical norms

Identifying companies trading at prices that appear reasonable relative to their historical earnings power.

Criterion 6

Free Cash Flow

What we measure: Cash generation and capital allocation

Free cash flow is used as the basis for valuation and signals the ability to return value to shareholders.

How We Score

Each criterion is scored from 0 to 100, then weighted to produce a Formula Alignment Score (0–100).

Alignment Level Description
High AlignmentPassed our strictest historical formula thresholds
Moderate AlignmentQuality businesses at fair prices
NeutralScore within mid-range
Watch ListMonitor for data changes
Low AlignmentDoes not meet minimum research criteria

Intrinsic Value & Margin of Safety

Beyond scoring, we calculate each ticker's intrinsic value snapshot using a two-stage discounted cash flow (DCF) formula:

Margin of Safety = the percentage discount between current price and intrinsic value. This gives a concrete measure of the ticker's alignment with value investing data.
