Building a Quality Factor from Profitability and Growth Stability

Summary

This report describes a fundamental equity quality framework spanning profitability, growth stability, earnings quality, cash flow, operating efficiency, and solvency. It screens factors for historical long-term return behavior, then builds a composite centered on profitability and stable growth. Profitability combines return on assets, return on equity, return on invested capital, and expected return on equity; growth stability is measured from the variability of multi-year annual growth in profit measures.

In the reported tests, profitability factors and their composite showed positive excess returns among high-ranked stocks and negative excess returns among low-ranked stocks. Growth-variability factors were used to exclude stocks with less stable growth. The resulting quality factor reportedly outperformed an earlier version across tested index universes. The report also links factor behavior to monetary conditions and earnings expectations, while noting that the relationship between liquidity and factor performance may shift. The evidence is historical and based on Chinese equities; the summary provides no detailed statistics, and the authors caution that the findings require judgment in practical use.

Key ideas

• The quality framework evaluates profitability, growth stability, earnings quality, cash flow, operations, and solvency.
• Profitability and stable growth contributed more useful selection signals than the other examined categories.
• A composite uses several profitability measures alongside measures of variability in historical profit growth.
• The updated quality factor reportedly performed better than its earlier version across the examined index universes.
• Monetary conditions and earnings expectations are associated with quality-factor performance, but their relationships may vary.
• The conclusions rely on historical evidence and should not be treated as universally reliable forecasts.
