Compare two fictional factor sets
| Factor | Issuer A | Issuer B |
|---|---|---|
| Net margin | 10% | 5% |
| Asset turnover | 1.0× | 2.0× |
| Equity multiplier | 2.0× | 2.0× |
| ROE product | 20% | 20% |
Describe the mathematical distinction
Issuer B has half the margin and twice the turnover in this example. Equal products do not mean the statements, operating risks or earnings quality are identical.
Investigate persistence separately
The factor values alone do not prove which company has a more sustainable return. Accounting scope, business conditions and the causes of each factor need further evidence.
