Using Asset Turnover and Profit Margin to Forecast Changes in Profitability

Financial statement analysis textbooks advocate disaggregating profitability into asset turnover and profit margin in performing financial analysis. In spite of the prominence of this technique, there is no evidence demonstrating its usefulness in a forecasting context. We provide evidence that disaggregating return on assets into asset turnover and profit margin does not provide incremental information for forecasting the change in return on assets one year ahead, but that disaggregating the change in return on assets into the change in asset turnover and the change in profit margin is useful in forecasting the change in return on assets one year ahead.

The Differential Persistence of Accruals and Cash Flows for Future Operating Income Versus Future Profitability

Prior research provides evidence that a higher proportion of accrued relative to cash earnings is associated with lower earnings performance in the subsequent fiscal year. The result has been widely interpreted as indicative of higher levels of operating accruals relative to cash flows foreshadowing a subsequent “earnings reversal,” and thus signaling earnings management. We note, however, that earnings performance in prior studies is typically defined as one-year-ahead operating income divided by one-year-ahead invested capital, or a measure of profitability. We find that accruals are more highly associated than cash flows with invested capital in the denominator of the profitability measure. In contrast, accruals and cash flows have no differential relation to one-year-ahead operating income. The evidence is not consistent with accruals having a reversal effect on earnings. This suggests that the lower persistence of accruals versus cash flows may not be due to earnings management but may rather be due to the effect of growth on future profitability.
