Earnings quality

From 10-Q / 10-K XBRL filings. Sloan (1996) accruals: high accruals relative to assets have historically preceded earnings disappointments. Descriptive research, not a prediction.

1 / 5
Poor — accruals are doing the heavy lifting
Reported profits have been driven more by accounting accruals than cash. Latest quarter: accruals equal -2.5% of assets — in the weakest quintile of large caps.
CY2024Q3Accruals / assets (TTM)CY2026Q2

Depreciation is disclosed annually by most filers, so quarterly values blend actuals with estimates — flagged on every reading. Method: TTM Sloan accruals ÷ average assets, scored 1–5 by quintile.
