Different questions, stated rules.

A combined score: 50% value, 25% price performance and 25% financial strength.

Companies are ranked on value, price performance and financial strength, then combined using the stated weights. A high result requires support from more than one part of the record.

The lowest valuation group, ordered by six-month price performance.

The screen starts with the cheapest tenth of the market on the six-measure Value Composite 2 score, then orders that group by six-month price performance.

A combined value and financial-strength score that penalises weakness in either measure.

The geometric mean falls when either value or financial strength is weak. A low valuation therefore does not compensate fully for weak company figures.

Large, liquid and profitable non-utilities ordered by dividend yield.

The screen starts with large, profitable and liquid non-utility companies, then orders the qualifying group by dividend yield.

Low earnings valuation with a Piotroski F-Score financial-strength test.

Companies must rank cheaply on earnings and also pass the stated Piotroski F-Score threshold. The financial test is shown separately on each company page.

The cheapest tenth of the market on six valuation measures.

Value Composite 2 compares P/E, P/S, P/B, P/CF, EBITDA/EV and shareholder yield. This page shows the cheapest decile before any price-performance test.

Operating earnings before depreciation relative to enterprise value.

Enterprise value includes equity and net debt. Dividing EBITDA by enterprise value provides one earnings-based comparison across different capital structures.

Higher price-to-book companies that rank cheaply on other valuation measures.

The screen finds companies that look expensive against book value but cheaper against earnings, sales and cash flow. It is useful where book assets explain little of the business.

Companies ranked on value against others in the same sector.

Valuation levels differ by industry. This screen compares each company with its own sector so a sector-wide valuation difference does not dominate the result.

Piotroski F-Score of at least 7 with an above-median value rank.

The nine-point Piotroski test covers profitability, leverage, liquidity and operating efficiency. This screen requires at least seven points and an above-median value rank.

Return on equity above 15%, margins above 10%, debt to equity below 1 and growing revenue.

Companies must pass the stated profitability, margin, leverage and revenue-growth tests. Each underlying figure is available on the company page.

Internally funded buybacks with supporting valuation and company figures.

The screen favours companies that fund buybacks internally rather than with additional debt, while also passing the stated valuation and financial-strength tests.

At least five consecutive years of earnings growth with a value floor.

Companies must have increased earnings per share in each of at least five consecutive measured years and also pass the stated minimum value rank.

Price to sales below 1.5, five-year earnings consistency, then ordered by price performance.

The screen starts with consistent earners, requires a price-to-sales ratio below 1.5, then orders the remaining companies by 12-to-1-month price performance.

Revenue growth of at least 10% with P/E no higher than 25 and a financial-strength test.

Companies must meet the stated revenue-growth and P/E limits and pass the screen's financial-strength requirement.

Twelve-to-one-month price performance divided by one-year volatility.

Dividing the completed price return by volatility reduces the rank of companies whose return came with larger price variation.

Twelve-to-one-month price performance of at least 15% with volatility no higher than 50%.

Companies must pass the stated completed-return and one-year volatility limits, then are ordered by risk-adjusted price performance.

Dividend yield plus the net effect of shares bought back or issued.

Shareholder yield adds dividend yield and net buyback yield. The list is ordered by that combined figure and does not add a separate financial-strength test.

Dividend yield of at least 3% with free-cash-flow yield of at least 4%.

The screen applies the stated dividend and free-cash-flow yield thresholds. The company page shows the underlying cash and balance-sheet figures.

Above-average market value, shares, cash flow per share and revenue; utilities excluded.

Companies must exceed the market averages for market value, shares outstanding, cash flow per share and revenue. Utilities are excluded.

Companies valued at $25 million to $250 million, with low price to sales and positive price performance.

This screen applies the stated market-value, price-to-sales and price-performance rules. Micro-companies can have limited liquidity, sparse coverage and large price moves.

Small and micro-companies with a high value rank and a Piotroski F-Score test.

The screen combines the stated company-size range with a high relative value rank and the required Piotroski F-Score. Liquidity and funding risk still need checking.

The lowest one-year volatility readings among companies with positive price performance.

The list starts with companies whose completed price performance is positive, then orders them from lower to higher one-year volatility.
