The Accrual Anomaly as a Chinese Equity Selection Factor
Summary
This research summary examines the accrual anomaly in A-shares: accounting earnings attributable to accruals appear less persistent than earnings supported by cash flow, while market prices do not fully reflect that difference. Its regression analysis finds a smaller coefficient for the accrual component than for the cash-flow component in predicting subsequent profits, and reports that the anomaly has been pronounced in recent years.
Portfolio tests sort the broad market by an accrual factor and report long-short effects, with stronger long-side excess and hedged returns after excluding loss-making firms. Returns are especially notable around earnings announcements. The factor shows results across many industries and improves several Chinese equity indices, with the strongest reported enhancement in the CSI 1000. An indirect accrual calculation with annual rebalancing performs better in factor grouping than the direct method. These are reported historical tests, not a guarantee of future performance; the summary flags model and factor decay and changes in market style as risks.
Key ideas
- The study reports that accrual-based earnings are less persistent than cash-flow-based earnings.
- Its analysis suggests market prices do not fully account for the difference in persistence.
- Sorting stocks by accruals produces reported long-short effects, which improve after excluding loss-making companies.
- A substantial share of the low-accrual group’s excess return is reported around earnings announcements.
- The indirect accrual calculation with annual rebalancing shows better grouping performance than the direct calculation.
- The reported results may weaken if the factor decays or market conditions change.
