Quality Ratio Score
The Quality Ratio (not to be confused with Earnings Quality) is a quantitative factor that determines how efficiently companies use their assets to generate high gross margin sales. Recently, modern finance has been looking to the Quality Ratio as a 5th key "Factor" that explains long-term equity investment returns.*
Companies with high quality ratios tend to have a large amount of gross profits to pay for marketing and R&D costs. They are theoretically well positioned to invest in their own futures.
The Quality Ratio Score ranks stocks by their Quality Ratio, giving the highest score to companies with the highest Quality Ratios and the lowest scores to companies with the lowest Quality Ratios.
* The other four factors are the Market Factor, Size (Market Cap), Value, and Momentum.
