Evaluating a publicly listed company requires more than a glance at its share price. Analysts and retail investors alike rely on a layered set of quantitative metrics to assess financial health, value, and price momentum. This article explains the key indicators commonly used in stock screening and fundamental analysis, using their definitions and calculation methods as the primary focus.
Shareholder Yield
Shareholder Yield measures how much capital a company returns to its shareholders through multiple channels. It is calculated by adding the dividend yield to the percentage of shares repurchased by the company. A variant popularised by fund manager Mebane Faber extends this calculation by also including the net debt repaid yield — meaning it accounts for debt reduction as another form of returning value.
A positive Shareholder Yield suggests the company is actively returning value, while a negative figure — particularly in the Mebane Faber variant — can indicate that the company is issuing new shares or taking on net new debt, effectively diluting or burdening shareholders rather than rewarding them. Investors often use Shareholder Yield as a baseline estimate of their real rate of return from holding a stock, independent of price appreciation.
Free Cash Flow Growth and the FCF Score
Free Cash Flow (FCF) is the cash a company generates after subtracting capital expenditures from operating cash flow. It represents the money available to meet financial obligations — servicing debt, paying dividends, or funding further investment — without needing to raise external capital.
FCF Growth is calculated as:
FCF Growth = (FCF Current Year - FCF Previous Year) / FCF Previous YearA negative FCF Growth figure indicates that free cash flow has declined year-over-year, which may signal increasing capital intensity, falling revenues, or rising costs.
The FCF Score combines FCF growth with FCF stability to give a single quality indicator. Higher scores are generally preferred, as they indicate either high free cash flow, low variability in free cash flow, or both. This composite view is more useful than raw FCF growth alone, since a company with modest but highly consistent cash generation may be more reliable than one with erratic but occasionally high FCF.
Gross Margin Score
The Gross Margin Score assesses both the level of a company’s gross margin and its stability over an eight-year period. The score is expressed on a scale from 1 to 100, where 1 represents the most stable and best-performing companies and 100 represents the least stable. A lower score is therefore preferable, as it indicates a company has maintained consistent gross margins over time — a sign of durable competitive positioning and operational discipline.
Valuation Scores
Piotroski F-Score
The Piotroski F-Score, developed by accounting professor Joseph Piotroski, is a nine-point scoring system designed to determine a company’s financial strength. Each point is earned by meeting a specific criterion across three categories:
- Profitability: Return on assets (ROA), cash flow return on assets (CFROA), change in ROA, and quality of earnings (whether cash flow exceeds net income).
- Leverage and Liquidity: Change in gearing, change in current ratio, and absence of new share issuance.
- Operating Efficiency: Change in gross margin and change in asset turnover ratio.
A score of 8 or 9 indicates a financially strong company, while a score of 1 or 2 signals financial weakness. Scores in the mid-range (4–6) are neutral. The F-Score is particularly useful as a filter to avoid financially distressed companies that may appear cheap on valuation metrics alone.
ERP5 Rank
The ERP5 Rank is a composite screening tool used to identify potentially undervalued companies. It combines four factors:
- Price-to-Book ratio
- Earnings Yield
- Return on Invested Capital (ROIC)
- Five-year average ROIC
A lower ERP5 rank suggests that a company is more undervalued relative to its peers. It is used primarily as a relative ranking tool across a universe of stocks rather than as an absolute measure.
MF Rank (Magic Formula)
The Magic Formula Rank (MF Rank) is derived from the investment strategy popularised by Joel Greenblatt in his book The Little Book That Beats the Market. The formula ranks companies based on two criteria:
- Earnings Yield: EBIT divided by Enterprise Value — a measure of how cheaply you are buying the company’s earnings.
- Return on Invested Capital (ROIC): A measure of how efficiently the company generates profits from its invested capital.
Companies are ranked on both metrics and the ranks are combined. A lower combined MF Rank indicates a company that is both good (high ROIC) and cheap (high earnings yield) — the central thesis of Greenblatt’s value investing approach.
Q.i. Value
The Q.i. Value is a composite valuation score calculated from four ratios:
- EBITDA Yield
- Earnings Yield
- Free Cash Flow Yield
- Liquidity
A lower Q.i. Value score suggests the company may be undervalued on a multi-factor basis. Like the ERP5 and MF Rank, it is best used comparatively across a screened universe of stocks rather than in isolation.
Value Composite Scores (VC1 and VC2)
The Value Composite One (VC1) scores a company on a 0–100 scale using five valuation ratios:
- Price-to-Book Value
- Price-to-Sales
- EBITDA-to-Enterprise Value
- Price-to-Cash Flow
- Price-to-Earnings
A score near 0 implies the stock appears undervalued across these metrics, while a score near 100 implies overvaluation. The Value Composite Two (VC2) uses the same five ratios but adds Shareholder Yield as a sixth factor, making it sensitive to how much cash the company returns to investors alongside its valuation profile.
Price Ratios
Several standard price-based ratios complete the fundamental picture:
- Price-to-Book (P/B): The current share price divided by book value per share. A ratio below 1 suggests the market values the company at less than its net assets; a negative P/B, however, indicates negative book value — meaning liabilities exceed assets.
- Price-to-Cash Flow (P/CF): Share price divided by operating cash flow per share. Negative values indicate negative operating cash flow.
- Price-to-Earnings (P/E): Share price divided by earnings per share. One of the most widely used valuation ratios. A negative P/E indicates the company is currently reporting a net loss.
Price Index and 52-Week Range
The Price Index measures the relative performance of a share price over a defined period. It is calculated by dividing the current share price by the share price at a set point in the past (e.g., one month or twelve months ago):
- A Price Index greater than 1.0 indicates the share price has increased over that period.
- A Price Index less than 1.0 indicates a price decline.
The 52-Week Price Range shows the ratio between the current price and the stock’s 52-week trading range. Investors use this to understand where a stock is trading relative to its recent historical high and low, which can inform decisions about entry points and risk.
Golden Cross: SMA 50/200
The Golden Cross is a technical indicator derived by dividing the 50-day Simple Moving Average (SMA) by the 200-day SMA:
- A ratio greater than 1 means the 50-day SMA is above the 200-day SMA — a classically bullish signal indicating positive short-term price momentum relative to the longer-term trend.
- A ratio less than 1 means the 50-day SMA has crossed below the 200-day SMA — often interpreted as a bearish signal, sometimes called a “Death Cross.”
While the Golden Cross is widely followed, it is a lagging indicator — it confirms trends that have already developed rather than predicting future moves. It is most useful when combined with fundamental analysis rather than used in isolation.
Using These Metrics Together
No single metric is sufficient to make an informed investment decision. Each indicator captures a different dimension of company performance:
- Valuation scores (VC1, VC2, ERP5, MF Rank, Q.i. Value) help identify whether a stock appears cheap or expensive relative to fundamentals.
- Quality metrics (Piotroski F-Score, Gross Margin Score, FCF Score) assess the underlying financial strength and consistency of the business.
- Return metrics (Shareholder Yield, FCF Growth) indicate how efficiently the company generates and distributes cash.
- Price and momentum indicators (Price Index, 52-Week Range, Golden Cross) provide context on recent market sentiment and trend direction.
Combining these dimensions — particularly screening for companies that score well on both valuation and quality metrics — is a cornerstone of systematic, quantitative value investing. Investors who understand what each metric measures, and more importantly what it does not measure, are better equipped to make disciplined, evidence-based portfolio decisions.
